[Code of Federal Regulations] [Title 16, Volume 1] [Revised as of January 1, 2005] From the U.S. Government Printing Office via GPO Access [CITE: 16CFR239.4] [Page 162] TITLE 16--COMMERCIAL PRACTICES CHAPTER I--FEDERAL TRADE COMMISSION PART 239_GUIDES FOR THE ADVERTISING OF WARRANTIES AND GUARANTEES --Table of Contents Sec. 239.4 ``Lifetime'' and similar representations. If an advertisement uses ``lifetime,'' ``life,'' or similar representations to describe the duration of a warranty or guarantee, then the advertisement should disclose, with such clarity and prominence as will be noticed and understood by prospective purchasers, the life to which the representation refers. Examples: These examples are for both print and broadcast advertising. These examples are illustrative, not exhaustive. Example A: (In an advertisement mentioning a lifetime guarantee on an automobile muffler where the duration of the guarantee is measured by the life of the car in which it is installed) ``Our lifetime guarantee on the Whisper Muffler protects you for as long as your car runs--even if you sell it, trade it, or give it away!'' Example B: (In an advertisement mentioning a lifetime guarantee on a battery where the duration of the warranty is for as long as the original purchaser owns the car in which it was installed) ``Our battery is backed by our lifetime guarantee. Good for as long as you own the car!''
