Accounting Policies [Abstract]
New Accounting Standards	Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standards Codification (“ASC”). The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have an immaterial impact on the Company’s consolidated financial statements. Adoption of new accounting standards In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270), Narrow-Scope Improvements, to provide clarity about the current requirements, rather than evaluate whether to expand or reduce interim disclosure requirements. The amendments in ASU 2025-11 result in a comprehensive list of interim disclosures that are required by GAAP. The amendments in ASU 2025-11 also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in ASU 2025-11 are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2025-11 can be applied either (1) prospectively or (2) retrospectively to any or all prior periods presented in the financial statements. The Company early adopted ASU 2025-11 prospectively in the first quarter of 2026. The adoption of ASU 2025-11 did not have a significant impact on its interim disclosures. Accounting standards issued but not yet adopted In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses, to improve financial reporting by requiring additional information about specific expense categories in the notes to the financial statements at interim and annual reporting periods. The amendments in ASU 2024-03 do not change or remove current expense disclosure requirements. The amendments require that at each interim and annual reporting period an entity should disclose the amounts of (a) purchase of inventory, (b) employee compensation, (c) depreciation and (d) intangible asset amortization included in each relevant expense caption. The amendments in ASU 2024-03 are effective for annual reporting periods beginning after December 1, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in ASU 2024-03 should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of ASU 2024-03 or (2) retrospectively to any or all periods presented in the financial statements. The adoption of ASU 2024-03 is expected to result in incremental disclosures in the Company’s financial statements. The Company will adopt the amendments in ASU 2024-03 prospectively upon the effective date. In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40), Targeted improvements to the Accounting for Internal-Use Software, to modernize the accounting for software costs that are accounted for under Subtopic 350-40. ASU 2025-06 removes all references to prescriptive and sequential software development stages throughout Subtopic 350-40. Therefore, an entity is required to start capitalizing software costs when both of the following occur: 1) Management has authorized and committed to funding the software project and 2) It is probable that the project will be completed and the software will be used to perform the function intended. The amendments in ASU 2025-06 are effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The amendments in ASU 2025-06 permit entities to use either 1) a prospective transition approach, 2) a modified transition approach, or 3) a retrospective transition approach. The Company is currently assessing the impact that ASU 2025-06 will have on its financial statements and expects to adopt the amendments in this update using the prospective transition approach. The Company expects that its capitalization of internal-use software costs will not change significantly under the amendments in ASU 2025-06. In May 2026, the FASB issued ASU 2026‑02, Environmental Credits and Environmental Credit Obligations (Topic 818). The ASU establishes a comprehensive accounting framework for the recognition, measurement, presentation, and disclosure of environmental credits and environmental credit obligations (“ECOs”). The guidance requires entities to recognize environmental credits as assets when it is probable that the credits will be used to settle an ECO, transferred in an exchange transaction, or used in a nonreciprocal transfer. Environmental credits are generally measured at cost, with subsequent accounting dependent on their intended use. Environmental credit obligations are recognized as liabilities when events occurring on or before the reporting date create an obligation, and such liabilities are measured based on the amount of credits required to settle the obligation, including both funded and unfunded portions. The ASU 2026-02 also requires entities to present environmental credits and related obligations on a gross basis in the balance sheet and to provide enhanced disclosures regarding the nature of environmental credit programs, the intended use of credits, and activity during the reporting period. The guidance is effective for public business entities for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. Adoption is required to be applied using a modified retrospective approach through a cumulative-effect adjustment to opening retained earnings as of the beginning of the annual reporting period of adoption. The Company is currently evaluating the impact of adopting ASU 2026‑02 on its consolidated financial statements and related disclosures. While the Company is continuing to assess the effect of the new guidance, the adoption may impact the recognition and presentation of environmental credits and related obligations, if applicable, as well as expand related disclosures.
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 rates 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. For certain 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 each hedge is entered into applying the same rationale concerning mitigating market risk that occurs from changes in interest rates and foreign exchange rates. The degree of judgment utilized in measuring the fair value of the instruments generally correlates to the level of pricing observability. Pricing observability is impacted by several factors, including the type of asset or liability, whether the asset or liability has an established market and the characteristics specific to the transaction. Instruments with readily active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment utilized in measuring fair value. Conversely, assets rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment utilized in measuring fair value. All the Company’s derivatives are classified as Level 2 financial instruments in the fair value hierarchy. Level 2 pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed. 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. For the three and six months periods ended June 30, 2026, the Company recorded an impairment loss of $9 million for its long-lived assets in connection with the restructuring activities in Türkiye in the second quarter of 2026.
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.
