Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements have been prepared on the same basis as the prior year audited financial statements and all adjustments considered necessary for a fair presentation have been included in the financial statements. All such adjustments are of a normal recurring nature. The results for the interim period are not necessarily indicative of the results to be expected for any future period or for the fiscal year ending December 31, 2018. The Condensed Consolidated Balance Sheet at December 31, 2017 has been derived from the audited financial statements at that date, but does not include all the information and footnotes required by U.S. GAAP for complete financial statements. On June 29, 2018 (the “Distribution Date”), Autoliv completed the spin-off of its former Electronics segment (the “spin-off”) through the distribution of all of the issued and outstanding stock of Veoneer, Inc. (“Veoneer”). To effect the spin-off, Autoliv distributed to each Autoliv stockholder one share of Veoneer common stock, par value $1.00 per share, for every one share of Autoliv common stock, par value $1.00 per share, held by such person on the common stock record date, and each Autoliv Swedish Depository Receipt (SDR) holder received one Veoneer SDR for each Autoliv SDR held by such person on the applicable SDR record date. On July 2, 2018, Veoneer’s common stock began regular-way trading on the New York Stock Exchange under the symbol “VNE” and its SDRs began trading on Nasdaq Stockholm under the symbol “VNE SDB.” The Company did not retain any equity interest in Veoneer. In accordance with U.S. GAAP, the financial position and results of operations of the Electronics business are presented as discontinued operations and, as such, have been excluded from continuing operations for all periods presented. The restated historical financial statements reflecting the spin-off are unaudited, but have been derived from Autoliv’s historical audited annual reports. The sum of the individual earnings per share amounts from continuing operations and discontinued operations may not equal the total company earnings per share amounts due to rounding. The cash flows and comprehensive income related to the Electronics business have not been segregated and are included in the Condensed Consolidated Statements of Cash Flows and Comprehensive Income, respectively, for all periods presented. With the exception of Note 3, the Notes to the Unaudited Condensed Consolidated Financial Statements reflect the continuing operations of Autoliv. See Note 3 - Discontinued Operations below for additional information regarding discontinued operations. On April 1, 2018, in preparation for the spin-off, pursuant to the terms of a master transfer agreement entered into between Autoliv and Veoneer, assets related to the Electronics business were transferred to, and liabilities related to the Electronics business were retained or assumed by Veoneer, however, responsibility for certain product, warranty and recall liabilities for Electronics products manufactured prior to April 1, 2018 was retained by Autoliv as provided in the Distribution Agreement between Autoliv and Veoneer. Certain amounts in the prior year’s condensed consolidated financial statements and related footnotes thereto have been reclassified to conform with the current year presentation as a result of the spin-off of Veoneer. Upon completion of the spin-off, Autoliv has concluded at June 30, 2018 that it has one reportable segment, based on the way the Company evaluates its financial performance and manages its operations. Prior to the completion of the spin-off, the Company had two reportable segments, Electronics and Passive Safety. The Company’s Passive Safety reportable segment includes the Company’s airbag and seatbelt products and components. Statements in this report that are not of historical fact are forward-looking statements that involve risks and uncertainties that could affect the actual results of the Company. A description of the important factors that could cause Autoliv’s actual results to differ materially from the forward-looking statements contained in this report may be found in this report and Autoliv’s other reports filed with the Securities and Exchange Commission (the “SEC”). For further information, refer to the consolidated financial statements, footnotes and definitions thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 22, 2018.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations	3. DISCONTINUED OPERATIONS As discussed in Note 1. Basis of Presentation above, on June 29, 2018, the Company completed the spin-off of Veoneer and the requirements for the presentation of Veoneer as a discontinued operation were met on that date. Accordingly, Veoneer’s historical financial results are reflected in the Company’s unaudited condensed consolidated financial statements as discontinued operations. The Company did not allocate any general corporate overhead or interest expense to discontinued operations. The financial results of Veoneer are presented as loss from discontinued operations, net of income taxes in the unaudited Condensed Consolidated Statements of Income. The following table presents the financial results of Veoneer (dollars in millions). Three months ended Nine months ended September 30, 2018 September 30, 2017 September 30, 2018 September 30, 2017 Net sales $ — $ 547.9 $ 1,122.9 $ 1,675.3 Cost of sales — (438.5 ) (898.4 ) (1,331.9 ) Gross profit — 109.4 224.5 343.4 Selling, general and administrative expenses — (22.3 ) (59.7 ) (67.1 ) Research, development and engineering expenses, net — (89.4 ) (224.0 ) (275.7 ) Amortization of intangibles — (6.1 ) (10.5 ) (29.7 ) Other income (expense), net — (0.1 ) (53.4 ) 12.5 Operating loss — (8.5 ) (123.1 ) (16.6 ) Loss from equity method investments — (9.9 ) (29.9 ) (17.7 ) Interest income — — 0.7 — Interest expense — — (0.4 ) (0.1 ) Other non-operating items, net — 0.2 0.5 (0.1 ) Loss before income taxes — (18.2 ) (152.2 ) (34.5 ) Income tax (expense) benefit — 0.2 (43.6 ) 2.5 Loss from discontinued operations, net of income taxes — (18.0 ) (195.8 ) (32.0 ) Less: Net loss attributable to non-controlling interest — (3.1 ) (8.3 ) (7.2 ) Net loss from discontinued operations $ — $ (14.9 ) $ (187.5 ) $ (24.8 ) The Company has incurred $79.4 million in separation costs related to the spin-off of Veoneer, of which $70.9 million has been incurred 2018 year to date and is reported in Other income (expense), net. These costs are primarily related to professional fees associated with planning the spin-off, as well as spin-off activities within finance, tax, legal and information system functions and certain investment banking fees incurred upon the completion of the spin-off. The following table summarizes the carrying value of major classes of assets and liabilities of Veoneer, reclassified as assets and liabilities of discontinued operations at December 31, 2017 (dollars in millions). December 31, 2017 ASSETS Receivables, net $ 460.5 Inventories, net 154.8 Other current assets 31.9 Total current assets, discontinued operations 647.2 Property, plant and equipment, net 364.2 Investments and other non-current assets 177.5 Goodwill 291.8 Intangible assets, net 122.2 Total non-current assets, discontinued operations $ 955.7 LIABILITIES Accounts payable $ 323.5 Accrued expenses 199.1 Other current liabilities 45.6 Total current liabilities, discontinued operations 568.2 Long-term debt 11.0 Pension liability 19.1 Other non-current liabilities 34.0 Total non-current liabilities, discontinued operations $ 64.1 In connection with the spin-off, Autoliv entered into definitive agreements with Veoneer that, among other matters, set forth the terms and conditions of the spin-off and provide a framework for Autoliv’s relationship with Veoneer after the spin-off, including the following (collectively, the “Spin-off Agreements”): Distribution Agreement The Distribution Agreement sets forth the principal transactions taken by Veoneer and by Autoliv in connection with the spin-off and the terms to govern certain aspects of the parties’ relationship following the spin-off. The Distribution Agreement also provides for cross-indemnities that, except as otherwise provided in the Distribution Agreement, are principally designed to place financial responsibility for the obligations and liabilities of Veoneer’s business with Veoneer and financial responsibility for the obligations and liabilities of Autoliv’s business with Autoliv. However, Autoliv has agreed to indemnify Veoneer for certain warranty, recall and product liabilities for Electronics products manufactured prior to April 1, 2018, and has retained an indemnification liability. Amended and Restated Transition Services Agreement Pursuant to the Amended and Restated Transition Services Agreement, Autoliv or one of its subsidiaries will provide various services to Veoneer and its subsidiaries and Veoneer or one of its subsidiaries agreed to provide various services to Autoliv and subsidiaries of Autoliv for a limited time to help ensure an orderly transition following the spin-off. The services will terminate no later than March 31, 2020. Employee Matters Agreement The Employee Matters Agreement governs Autoliv’s and Veoneer’s compensation and employee benefit obligations with respect to the employees and non-employee directors of each company. Pursuant to the Agreement, the Company transferred to Veoneer pension benefits and postretirement benefits other than pension related to Veoneer employees. The transfer of assets and obligations to Veoneer resulted in a net decrease in the underfunded status of the sponsored pension and postretirement benefits other than pension of $22.8 million and the transfer of unrecognized losses in accumulated other comprehensive income of $6.3 million on the Distribution Date. Tax Matters Agreement Pursuant to the Tax Matters Agreement, Autoliv and Veoneer allocated the liability for taxes and certain tax assets between the two companies. The Tax Matters Agreement also governs the parties’ respective rights, responsibilities, and obligations with respect to U.S. federal, state, local and foreign taxes (including taxes arising in the ordinary course of business and taxes, if any, incurred as a result of any failure of the spin-off and certain related transactions to qualify as tax-free for U.S. federal income tax purposes), tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings, and assistance and cooperation in respect of tax matters. Pursuant to the Tax Matters Agreement, Autoliv is the primary obligor on all taxes which relate to any period prior to April 1, 2018. Consequently, the Company is liable for any transition taxes under the Tax Cuts and Jobs Act of 2017. Reseller Agreements Reseller agreements are primarily comprised of arrangements between Veoneer and Autoliv business units in Japan, the U. S., India and Sweden to address situations in which customers have not yet been able to update their systems to reflect Veoneer as the supplier. Under the terms of these agreements and based on the substance of the relationships with the customers, Veoneer has the responsibility to provide the products to the customers although orders may be placed with Autoliv and Autoliv may collect the cash for the associated invoices which is then remitted to Veoneer. Veoneer Capital Contribution In connection with the spin-off, Autoliv capitalized Veoneer with approximately $1 billion of cash. Net assets of $2 , The following table presents depreciation, amortization, capital expenditures, acquisition of businesses and significant non-cash items of the discontinued operations related to Veoneer (dollars in millions).

Revenue From Contract With Customer [Abstract]
Revenue	4. REVENUE In accordance with ASC 606, Revenue from Contracts with Customers In addition, from time to time, Autoliv may make payments to customers in connection with ongoing and future business. These payments to customers are generally recognized as a reduction to revenue at the time of the commitment to make these payments unless certain criteria are met warranting capitalization. The Company considers qualitative factors such as the maturity of the product and technology involved in a potential transaction as well as how current the customer relationship is, when evaluating if a payment(s) warrant capitalization. If the payments are capitalized, the amounts are amortized to revenue as the related goods are transferred. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control of a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of sales. Nature of goods and services The following is a description of principal activities from which the Company generates its revenue. The Company has after the spin-off of its Electronics business one operating segment, Passive Safety, which includes airbag and seatbelt products and components. The Company generates revenue from the sale of production parts to original equipment manufacturers (“OEMs”). The Company accounts for individual products separately if they are distinct (i.e., if a product is separately identifiable from other items and if a customer can benefit from it on its own or with other resources that are readily available to the customer). The consideration, including any price concessions or annual price adjustments, is based on their stand-alone selling prices for each of the products. The stand-alone selling prices are determined based on the cost-plus margin approach. The Company recognizes revenue for production parts primarily at a point in time. For production parts with revenue recognized at a point in time, the Company recognizes revenue upon shipment to the customers and transfer of title and risk of loss under standard commercial terms (typically FOB shipping point). There are certain contracts where the criteria to recognize revenue over time have been met (e.g., there is no alternative use to the Company and the Company has an enforceable right to payment). In such cases, at period end, the Company recognizes revenue and a related asset and associated cost of goods sold and inventory. However, the financial impact of these contracts is immaterial considering the very short production cycles and limited inventory days on hand, which is typical for the automotive industry. The amount of revenue recognized is based on the purchase order price and adjusted for variable consideration (i.e. price concessions or annual price adjustments).

Fair Value Disclosures [Abstract]
Fair Value Measurement	5. FAIR VALUE MEASUREMENTS Assets and liabilities measured at fair value on a recurring basis The carrying value of cash and cash equivalents, accounts receivable, accounts payable, other current liabilities and short-term debt approximate their fair value because of the short-term maturity of these instruments. The Company uses derivative financial instruments, “derivatives”, as part of its debt management to mitigate the market risk that occurs from its exposure to changes in interest and foreign exchange rates. The Company does not enter into derivatives for trading or other speculative purposes. The Company’s use of derivatives is in accordance with the strategies contained in the Company’s overall financial policy. All derivatives are recognized in the consolidated financial statements at fair value. Certain derivatives are from time to time designated either as fair value hedges or cash flow hedges in line with the hedge accounting criteria. For certain other derivatives hedge accounting is not applied either because non-hedge accounting treatment creates the same accounting result or the hedge does not meet the hedge accounting requirements, although entered into applying the same rationale concerning mitigating market risk that occurs from changes in interest and foreign exchange rates. The The tables below present information about the Company’s derivative financial assets and liabilities measured at fair value on a recurring basis for the continuing operations. The carrying value is the same as the fair value as these instruments are recognized in the consolidated financial statements at fair value. Although the Company is party to close-out netting agreements (ISDA agreements) with all derivative counterparties, the fair values in the tables below, in the Condensed Consolidated Balance Sheets at September 30, 2018 and December 31, 2017, have been presented on a gross basis. According to the close-out netting agreements, transaction amounts payable to a counterparty on the same date and in the same currency can be netted. The amounts subject to netting agreements that the Company chose not to offset are presented below.

Derivatives designated as hedging instruments There were no derivatives designated as hedging instruments as of September 30, 2018 and December 31, 2017 related to the continuing operations. Derivatives not designated as hedging instruments Derivatives not designated as hedging instruments relate to economic hedges and are marked to market with all amounts recognized in the Consolidated Statements of Income. The derivatives not designated as hedging instruments outstanding at September 30, 2018 and December 31, 2017 related to the continuing operations were foreign exchange swaps. For the three months ended September 30, 2018 and September 30, 2017, the gains and losses recognized in other non-operating items, net were a gain of $1.0 million and a loss of $0.9 million, respectively, for derivative instruments not designated as hedging instruments. For the nine months ended September 30, 2018 and September 30, 2017, the gains and losses recognized in other non-operating items, net were a loss of $4.3 million and a loss of $0.5 million, respectively. For the three and nine months ended September 30, 2018 and September 30, 2017, the gains and losses recognized as interest expense were immaterial. Fair Value of Debt The fair value of long-term debt is determined either from quoted market prices as provided by participants in the secondary market or for long-term debt without quoted market prices, estimated using a discounted cash flow method based on the Company’s current borrowing rates for similar types of financing. The Company has determined that each of these fair value measurements of debt reside within Level 2 of the fair value hierarchy. On June 18, 2018, Autoliv announced that it priced a 5-year bond offering of EUR 500 million in the Eurobond market (the “Notes”). The Notes were issued on June 26, 2018, at an issue price of 99.527%, and carry a coupon of 0.75% (paid annually in arrears), which implies a per annum yield of 0.847%. The fair value and carrying value of debt for the continuing operations is summarized in the table below (dollars in millions).

Assets and liabilities measured at fair value on a nonrecurring basis In addition to assets and liabilities that are measured at fair value on a recurring basis, the Company also has assets and liabilities in its balance sheet that are measured at fair value on a nonrecurring basis including certain long-lived assets, including equity method investments, goodwill and other intangible assets, typically as it relates to impairment. The Company has determined that the fair value measurements included in each of these assets and liabilities rely primarily on Company-specific inputs and the Company’s assumptions about the use of the assets and settlements of liabilities, as observable inputs are not available. The Company has determined that each of these fair value measurements reside within Level 3 of the fair value hierarchy. To determine the fair value of long-lived assets, the Company utilizes the projected cash flows expected to be generated by the long-lived assets, then discounts the future cash flows over the expected life of the long-lived assets.

Income Tax Disclosure [Abstract]
Income Taxes	6. INCOME TAXES The effective tax rate in the third quarter of 2018 was 31.1% compared to 29.5% in the same quarter of 2017. Discrete tax items, net in the third quarter of 2018 had a unfavorable impact of 0.2%. In the third quarter of 2017, discrete tax items, net had an unfavorable impact of 2.8%. The effective tax rate in the first nine months of 2018 was 23.0% compared to 29.2% for the first nine months of 2017. The effective tax rate in the first nine months of 2018 was favorably impacted by 5.3%, due to discrete tax items, principally the reversal of valuation allowances against deferred tax assets recorded in the second quarter. In December 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. For the nine months ended September 30, 2018, the Company did not have the necessary information analyzed to revise the provisional amount initially recorded for the transition tax for the year ended December 31, 2017. As a result, the Company did not make any adjustment to the provisional transition tax recorded in December 2017. Additional work is still necessary for a more detailed analysis of the Company's deferred tax assets and liabilities and its historical foreign earnings as well as potential correlative adjustments. Any subsequent adjustment to these amounts will be recorded to current tax expense in the fourth quarter of 2018 when the analysis is complete. The Company files income tax returns in the United States federal jurisdiction, and various states and non-U.S. jurisdictions. At any given time, the Company is undergoing tax audits in several tax jurisdictions covering multiple years. The Company is no longer subject to income tax examination by the U.S. federal income tax authorities for years prior to 2014. With few exceptions, the Company is no longer subject to income tax examination by U.S. state or local tax authorities or by non-U.S. tax authorities for years before 2009. As of September 30, 2018, the Company is not aware of any proposed income tax adjustments resulting from tax examinations that would have a material impact on the Company’s condensed consolidated financial statements. The conclusion of such audits could result in additional increases or decreases to unrecognized tax benefits in some future period or periods. During the third quarter of 2018, the Company recorded a net decrease of $0.2 million to income tax reserves for unrecognized tax benefits based on tax positions related to the current year, including accruing additional interest related to unrecognized tax benefits of prior years. In addition, during the third quarter of 2018, the Company recorded a decrease of $2.2 million to income tax reserves for unrecognized tax benefits of prior years due to settlements with tax authorities. Of the total unrecognized tax benefits of $29.8 million recorded at September 30, 2018, $4.1 million is classified as current tax payable and $25.7 million is classified as non-current tax payable on the Condensed Consolidated Balance Sheet.

Restructuring And Related Activities [Abstract]
Restructuring	8. RESTRUCTURING Restructuring provisions are made on a case-by-case basis and primarily include severance costs incurred in connection with headcount reductions and plant consolidations. The Company expects to finance restructuring programs over the next several years through cash generated from its ongoing operations or through cash available under existing credit facilities. The Company does not expect that the execution of these activities will have a material adverse impact on its liquidity position. The changes in the employee-related reserves have been charged against Other income (expense), net in the Consolidated Statements of Income. The majority of the reserve balance as of September 30, 2018 pertains to restructuring activities initiated in Western Europe over the past few years. The Company anticipates that its restructuring initiatives in Western Europe for a number of plants, none of which are individually or in the aggregate material as of September 30, 2018, will continue through dates ranging from 2018 through 2021. The total amount of costs expected to be incurred in connection with these restructuring activities ranges from approximately $10 million to $28 million for each individual activity. In the aggregate, the cost for these Western European restructuring initiatives is approximately $101 million and the remaining restructuring liability as of September 30, 2018 is approximately $29 million out of the $32.5 million total reserve balance.

Compensation And Retirement Disclosure [Abstract]
Retirement Plans	10. RETIREMENT PLANS The Company’s most significant retirement plan is the U.S. plan for which the benefits are based on an average of the employee’s earnings in the years preceding retirement and on credited service. In a prior year, the Company closed participation in the Autoliv ASP, Inc. Pension Plan to exclude those employees hired after December 31, 2003. Within the U.S. there is also a non-qualified restoration plan that provides benefits to employees whose benefits in the primary U.S. plan are restricted by limitations on the compensation that can be considered in calculating their benefits. In December 2017 the Company decided to amend the U.S. defined pension plan, communicating a benefits freeze that will begin on December 31, 2021. For the Company’s non-U.S. defined benefit plans the most significant individual plan resides in the U.K. The Company has closed participation in the U.K. defined benefit plan to exclude all employees hired after April 30, 2003 with few members accruing benefits. The Net Periodic Benefit Costs from continuing operations related to Other Post-retirement Benefits were not significant to the condensed consolidated financial statements of the Company for the three and nine month periods ended September 30, 2018 and September 30, 2017 and are not included in the table below.

Commitments And Contingencies Disclosure [Abstract]
Contingent Liabilities	12. CONTINGENT LIABILITIES Legal Proceedings Various claims, lawsuits and proceedings are pending or threatened against the Company or its subsidiaries, covering a range of matters that arise in the ordinary course of its business activities with respect to commercial, product liability and other matters. Litigation is subject to many uncertainties, and the outcome of any litigation cannot be assured. After discussions with counsel, and with the exception of losses resulting from the antitrust proceedings described below, it is the opinion of management that the various legal proceedings and investigations to which the Company currently is a party will not have a material adverse impact on the consolidated financial position of Autoliv, but the Company cannot provide assurance that Autoliv will not experience material litigation, product liability or other losses in the future. In October 2014, one of the Company’s Brazilian subsidiaries received a notice of deficiency from the state tax authorities from the state of São Paulo, Brazil which, primarily, alleged violations of ICMS (VAT) payments and improper warehousing documentation. The aggregate assessment for all alleged violations was R$81 million (approximately $21 million), inclusive of fines, penalties and interest. The Company believed that a loss was probable with respect to at least a portion of the assessed amount and accrued an not material to the Company’s results of operations During the first quarter of 2018, the Brazilian authorities offered an amnesty period which would allow taxpayers to reduce the penalties associated with eligible tax matters by up to 85%. Company applied to ANTITRUST MATTERS Authorities in several jurisdictions are currently conducting or have conducted broad, and in some cases, long-running investigations of suspected anti-competitive behavior among parts suppliers in the global automotive vehicle industry. These investigations include, but are not limited to, the products that the Company sells. European Commission (“EC”) Investigations: On June 7-9, 2011, representatives of the European Commission (“EC”), the European antitrust authority, visited two facilities of a Company subsidiary in Germany to gather information for an investigation of anti-competitive behavior among suppliers of occupant safety systems. On November 22, 2017, the EC concluded a discrete portion of its investigation and imposed a fine on the Company of EUR 8.1 million (approximately $9.7 million) with respect to this portion of the EC’s overall investigation while it continues the more significant portion of its investigation. The Company paid this amount during the first quarter of 2018, and had previously accrued EUR 8.3 million (approximately $9.9 million) in 2017 with respect to this discrete portion of the investigation. Management does not believe the outcome of this discrete portion of the EC’s investigation provides an indication of the total probable loss associated with the EC investigation as a whole. The Company remains unable to estimate the financial impact of what the Company believes to be the substantially more significant, continuing portion of the investigation or predict the reporting periods in which such financial impact may be recorded. Consequently, the Company has not recorded a provision for loss as of September 30, 2018 other than as noted above for the discrete portion of the investigation. However, management believes it is probable that the Company’s operating results and cash flows will be materially adversely impacted for the reporting periods in which the continuing portion of the investigation is resolved or becomes estimable. South Africa Investigation: Brazil Investigation Civil Litigation In May 2014, the Company, without admitting any liability, entered into separate settlement agreements with the direct purchasers, auto dealers, end-payors plaintiff classes, which were granted final approval by the MDL court in 2015 and 2016. The total settlement amount of $65 million (later reduced to approximately $60.5 million as a result of opt-outs from the direct purchaser settlement) was expensed in 2014. In April 2016, the Company entered into a settlement agreement with the truck and equipment dealers’ class, which was granted final approval by the MDL court in 2016, for an amount that is immaterial to the Company’s results of operations. The class settlements do not resolve any claims of settlement class members who opt-out of the settlements or the unasserted claims of any purchasers of occupant safety systems who are not otherwise included in a settlement class, such as states and municipalities. Two direct purchasers opted out of the Company’s direct purchaser class settlement and several individuals and one insurer (and its affiliated entities) opted-out of the end-payor class settlements, including the Company’s settlement. In September 2016, the insurer (and its affiliated entities) that opted out of the end-payor class settlement filed an antitrust lawsuit in the United States District Court for the Eastern District of Michigan, the venue for the MDL, against the Company and the other settling defendants in the end-payor class settlements. The defendants’ motion to dismiss the complaint on various grounds was granted in part and denied in part in August 2018. The Company understands that the insurer may attempt to correct the pleading deficiencies identified in the Court’s decision. The Company cannot predict or estimate the duration or ultimate outcome of this matter. In March 2015, the Company, without admitting any liability, reached agreements regarding additional settlements to resolve certain direct purchasers’ global (including U.S.) or non-U.S. antitrust claims that were not covered by the direct purchaser class settlement. The total amount of these additional settlements was $81 million. Autoliv expensed during the first quarter of 2015 approximately $77 million as a result of these additional settlements, net of existing amounts that had been accrued in 2014. The remaining four antitrust class action lawsuits were filed in Canada (Sheridan Chevrolet Cadillac Ltd. et al. v. Autoliv, Inc. et al., filed in the Ontario Superior Court of Justice on January 18, 2013; M. Serge Asselin v. Autoliv, Inc. et al., filed in the Superior Court of Quebec on March 14, 2013; Ewert v. Autoliv, Inc. et al., filed in the Supreme Court of British Columbia on July 18, 2013; and Cindy Retallick and Jagjeet Singh Rajput v. Autoliv ASP, Inc. et al., filed in the Queen’s Bench of the Judicial Center of Regina in the province of Saskatchewan on May 14, 2014) asserting claims on behalf of putative classes of both direct and indirect purchasers of occupant safety systems. In February 2017, the Company entered into, and the courts subsequently approved, a settlement agreement with plaintiffs in three of the four class actions to settle on a nationwide class basis for an amount that is not material to the Company’s results of operations. Settlement amounts were accrued for this matter during the period ended December 31, 2016 and final payment of the accrued amounts was made in 2017. This national settlement includes the claims of the putative members of the fourth class action. PRODUCT WARRANTY, RECALLS AND INTELLECTUAL PROPERTY Autoliv is exposed to various claims for damages and compensation if its products fail to perform as expected. Such claims can be made, and result in costs and other losses to the Company, even where the product is eventually found to have functioned properly. Where a product (actually or allegedly) fails to perform as expected, the Company may face warranty and recall claims. Where such (actual or alleged) failure results, or is alleged to result, in bodily injury and/or property damage, the Company may also face product liability and other claims. There can be no assurance that the Company will not experience material warranty, recall or product (or other) liability claims or losses in the future, or that the Company will not incur significant costs to defend against such claims. The Company may be required to participate in a recall involving its products. Each vehicle manufacturer has its own practices regarding product recalls and other product liability actions relating to its suppliers. As suppliers become more integrally involved in the vehicle design process and assume more of the vehicle assembly functions, vehicle manufacturers are increasingly looking to their suppliers for contribution when faced with recalls and product liability claims. Government safety regulators may also play a role in warranty and recall practices. A warranty, recall or product-liability claim brought against the Company in excess of its insurance may have a material adverse effect on the Company’s business. Vehicle manufacturers are also increasingly requiring their outside suppliers to guarantee or warrant their products and bear the costs of repair and replacement of such products under new vehicle warranties. A vehicle manufacturer may attempt to hold the Company responsible for some, or all, of the repair or replacement costs of products when the product supplied did not perform as represented by us or expected by the customer. Accordingly, the future costs of warranty claims by the customers may be material. However, the Company believes its established reserves are adequate. Autoliv’s warranty reserves are based upon the Company’s best estimates of amounts necessary to settle future and existing claims. The Company regularly evaluates the adequacy of these reserves, and adjusts them when appropriate. However, the final amounts actually due related to these matters could differ materially from the Company’s recorded estimates. In addition, as vehicle manufacturers increasingly use global platforms and procedures, quality performance evaluations are also conducted on a global basis. Any one or more quality, warranty or other recall issue(s) (including those affecting few units and/or having a small financial impact) may cause a vehicle manufacturer to implement measures such as a temporary or prolonged suspension of new orders, which may have a material impact on the Company’s results of operations. The Company carries insurance for potential recall and product liability claims at coverage levels based on our prior claims experience. In addition, a number of the agreements entered into by the Company, including the Spin-off Agreements, require Autoliv to indemnify the other parties for certain claims. Autoliv cannot assure that the level of coverage will be sufficient to cover every possible claim that can arise in our businesses or with respect to other obligations, now or in the future, or that such coverage always will be available should we, now or in the future, wish to extend, increase or otherwise adjust our insurance. Toyota Recall: As previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, the Company determined pursuant to ASC 450 that a loss with respect to this issue is reasonably possible. If the Company is obligated to indemnify Toyota for the costs associated with the Toyota Recall, the Company expects that its insurance will generally cover such costs and liabilities and estimates that the Company’s loss, net of expected insurance recoveries, would be less than $20 million. However, the ultimate costs of the Toyota Recall could be materially different. The main variables affecting the ultimate cost for the Company are: the determination of proportionate responsibility (if any) among Toyota, the Company, and any relevant sub-suppliers; the ultimate number of vehicles repaired; the cost of repair per vehicle; and the actual recoveries from sub-suppliers and insurers. The Company’s insurance policies generally include coverage of the costs of a recall, although costs related to replacement parts are generally not covered. In its products, the Company utilizes technologies which may be subject to intellectual property rights of third parties. While the Company does seek to procure the necessary rights to utilize intellectual property rights associated with its products, it may fail to do so. Where the Company so fails, the Company may be exposed to material claims from the owners of such rights. Where the Company has sold products which infringe upon such rights, its customers may be entitled to be indemnified by the Company for the claims they suffer as a result thereof. Such claims could be material. The table in Note 9. Product-Related Liabilities above summarizes the change in the balance sheet position of the product related liabilities.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Incentive Plan	13. STOCK INCENTIVE PLAN Eligible employees of Autoliv participate in Autoliv, Inc.1997 Stock Incentive Plan (the Plan) and received Autoliv stock-based awards which include stock options, restricted stock units and performance shares. In connection with the Veoneer spin-off, each outstanding Autoliv stock-based award as of June 29, 2018 was converted to stock awards that have underlying shares of both Autoliv and Veoneer common shares. The conversion that occurred on the Distribution Date was based on the following: • Stock Option (SOs) - A number of SOs comprising 50% of the value of the outstanding SOs calculated immediately prior to the spin-off continued to be applicable to Autoliv common stock. A number of SOs comprising the remaining 50% percent of the pre spin-off value were replaced with options to acquire shares of Veoneer common stock. Certain exceptions applied. • Restricted Stock Units (RSUs) - A number of RSUs comprising 50% of the value of the outstanding RSUs calculated immediately prior to the spin-off continued to be applicable to Autoliv common stock. A number of RSUs comprising the remaining 50% of the pre spin-off value were replaced with RSUs with underlying Veoneer common stock. Certain exceptions applied. • Performance Shares (PS) - Outstanding PSs pre spin-off were converted to time-based RSUs and shall be treated in the same manner as other outstanding RSUs (as described above) on the Distribution Date. The number of outstanding PSs pre spin-off were converted based on pro-ration of performance period such as: 1) The level of actual achievement of performance goals for each outstanding PS for the period between the first day of the performance period and December 31, 2017 (the “Performance Measurement Date”), referred to as “Level of Performance-to-Date” and; 2) The greater of the Level of Performance-to-Date and estimated target performance level (i.e., 100%) for the period between the Performance Measurement Date and the last day of the performance period. In each case above, the conversion was intended to generally preserve the intrinsic value of the original award determined as of the distribution date of Veoneer. The number of converted RSUs and SOs for Autoliv and Veoneer was based on the average of Autoliv closing stock prices for the last 5 days prior to the spin-off and the average of closing stock prices of Autoliv and Veoneer, respectively, for the first 5 days after the spin-off. As a result of the spin-off and the related conversion, it was determined that the stock based awards were modified in accordance with ASC 718, Compensation – Stock Compensation. The fair value of the RSUs and SOs immediately before and after the modification was assessed in order to determine if the modification resulted in any incremental compensation cost related to the awards, including consideration of the impact of conversion using the 5 day average. Based on the valuation performed, it was determined that the conversion did not result in any incremental compensation cost for any of the outstanding awards. The post spin-off stock-based compensation expense will be based on the original grant date fair value related to only Autoliv employees. With certain limited exceptions, including the freezing of the Performance Measurement Date to December 31, 2017 as noted above, the SOs and RSUs post spin-off are subject to the same terms and conditions (including with respect to vesting and expiration) that were applicable to such Autoliv stock-based awards immediately prior to the conversion and as described in the Audited Combined Financial Statements for the year ended December 31, 2017 and corresponding notes. The Company recorded approximately $2.3 million and $6.9 million stock-based compensation expense in continuing operations related to RSUs and PSs for the three and nine month periods ended September 30, 2018, respectively. During the three and nine month periods ended September 30, 2017, the Company recorded $2.6 million and $7.4 million, respectively, of stock-based compensation expense in continuing operations related to RSUs and PSs.

Earnings Per Share [Abstract]
Earnings per share	14. EARNINGS PER SHARE The Company calculates basic earnings per share (EPS) by dividing net income attributable to controlling interest by the weighted-average number of shares of common stock outstanding for the period (net of treasury shares). The Company’s unvested RSUs, of which some include the right to receive non-forfeitable dividend equivalents, are considered participating securities. The diluted EPS reflects the potential dilution that could occur if common stock were issued for awards under the Company’s Stock Incentive Plan and is calculated using the more dilutive method of either the two-class method or the treasury stock method. The treasury stock method assumes that the Company uses the proceeds from the exercise of stock option awards to repurchase ordinary shares at the average market price during the period. For unvested restricted stock, assumed proceeds under the treasury stock method will include unamortized compensation cost and windfall tax benefits or shortfalls. Post spin-off assumed proceeds under the treasury stock method related to RSUs will only include unamortized compensation cost related to Autoliv employees holding Autoliv RSUs. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator. For the three and nine month periods ended September 30, 2018, no shares were excluded from the computation of the diluted EPS. For the three and nine month periods ended September 30, 2017, approximately 0.1 million shares and 0.1 million shares of common stock, respectively, were not included in the computation of the diluted EPS, which could potentially dilute basic EPS in the future. During the three and nine month periods ended September 30, 2018, approximately 9 thousand and 0.2 million shares of common stock, respectively, from the treasury stock have been utilized by the Company’s Stock Incentive Plan. During the three and nine month periods ended September 30, 2017, approximately 30 thousand and 0.1 million shares of common stock, respectively, from the treasury stock were utilized by the Company’s Stock Incentive Plan. The computation of basic and diluted EPS under the two-class method were as follows: (In millions, except per share amounts) Three months ended Nine months ended September 30, 2018 September 30, 2017 September 30, 2018 September 30, 2017 Numerator: Basic and diluted: Net income from continuing operations 117.5 105.7 468.9 389.3 Net income from discontinued operations — (14.9 ) (187.5 ) (24.8 ) Net income attributable to controlling interest $ 117.5 $ 90.8 $ 281.4 $ 364.5 Participating share awards with dividend equivalent rights — — — — Net income available to common shareholders 117.5 90.8 281.4 364.5 Earnings allocated to participating share awards — — — — Net income attributable to common shareholders $ 117.5 $ 90.8 $ 281.4 $ 364.5 Denominator: Basic: Weighted average common stock 87.1 86.9 87.1 87.7 Add: Weighted average stock options/share awards 0.3 0.3 0.2 0.2 Diluted: 87.4 87.2 87.3 87.9 Basic EPS: Continuing operations $ 1.35 $ 1.22 $ 5.38 $ 4.44 Discontinued operations $ — $ (0.17 ) $ (2.15 ) $ (0.28 ) Basic EPS $ 1.35 $ 1.05 $ 3.23 $ 4.16 Diluted EPS: Continuing operations $ 1.34 $ 1.21 $ 5.37 $ 4.43 Discontinued operations $ — $ (0.17 ) $ (2.15 ) $ (0.28 ) Diluted EPS $ 1.34 $ 1.04 $ 3.22 $ 4.15

New Accounting Standards	Adoption of New Accounting Standards In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) – Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (AOCI) In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (“GILTI”) provisions of the Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. In the first quarter of 2018, the Company elected to treat any potential GILTI inclusions as a period cost.

Financial Instruments	The Company uses derivative financial instruments, “derivatives”, as part of its debt management to mitigate the market risk that occurs from its exposure to changes in interest and foreign exchange rates. The Company does not enter into derivatives for trading or other speculative purposes. The Company’s use of derivatives is in accordance with the strategies contained in the Company’s overall financial policy. All derivatives are recognized in the consolidated financial statements at fair value. Certain derivatives are from time to time designated either as fair value hedges or cash flow hedges in line with the hedge accounting criteria. For certain other derivatives hedge accounting is not applied either because non-hedge accounting treatment creates the same accounting result or the hedge does not meet the hedge accounting requirements, although entered into applying the same rationale concerning mitigating market risk that occurs from changes in interest and foreign exchange rates. The The Company has determined that the fair value measurements included in each of these assets and liabilities rely primarily on Company-specific inputs and the Company’s assumptions about the use of the assets and settlements of liabilities, as observable inputs are not available. The Company has determined that each of these fair value measurements reside within Level 3 of the fair value hierarchy. To determine the fair value of long-lived assets, the Company utilizes the projected cash flows expected to be generated by the long-lived assets, then discounts the future cash flows over the expected life of the long-lived assets.
Inventories	Inventories are stated at the lower of cost (principally FIFO) and net realizable value.
Restructuring Provisions	Restructuring provisions are made on a case-by-case basis and primarily include severance costs incurred in connection with headcount reductions and plant consolidations.
Contingent Liabilities	Autoliv’s warranty reserves are based upon the Company’s best estimates of amounts necessary to settle future and existing claims. The Company regularly evaluates the adequacy of these reserves, and adjusts them when appropriate. However, the final amounts actually due related to these matters could differ materially from the Company’s recorded estimates.

Conversion of stock description			The conversion that occurred on the Distribution Date was based on the following:  Stock Option (SOs) - A number of SOs comprising 50% of the value of the outstanding SOs calculated immediately prior to the spin-off continued to be applicable to Autoliv common stock. A number of SOs comprising the remaining 50% percent of the pre spin-off value were replaced with options to acquire shares of Veoneer common stock. Certain exceptions applied.  Restricted Stock Units (RSUs) - A number of RSUs comprising 50% of the value of the outstanding RSUs calculated immediately prior to the spin-off continued to be applicable to Autoliv common stock. A number of RSUs comprising the remaining 50% of the pre spin-off value were replaced with RSUs with underlying Veoneer common stock. Certain exceptions applied.  Performance Shares (PS) - Outstanding PSs pre spin-off were converted to time-based RSUs and shall be treated in the same manner as other outstanding RSUs (as described above) on the Distribution Date. The number of outstanding PSs pre spin-off were converted based on pro-ration of performance period such as: 1) The level of actual achievement of performance goals for each outstanding PS for the period between the first day of the performance period and December 31, 2017 (the “Performance Measurement Date”), referred to as “Level of Performance-to-Date” and; 1) The greater of the Level of Performance-to-Date and estimated target performance level (i.e., 100%) for the period between the Performance Measurement Date and the last day of the performance period. In each case above, the conversion was intended to generally preserve the intrinsic value of the original award determined as of the distribution date of Veoneer. The number of converted RSUs and SOs for Autoliv and Veoneer was based on the average of Autoliv closing stock prices for the last 5 days prior to the spin-off and the average of closing stock prices of Autoliv and Veoneer, respectively, for the first 5 days after the spin-off.
