uuWarranty Coverages u
Information
Replacement Battery Limited Warranty – provides prorated coverage for a
replacement battery purchased from your dealer.
Replacement Muffler Life time Limited Warranty – provides coverage for as
long as the purchaser of the muffler owns the vehicle.
Restrictions and exclusions apply to a ll these warranties. Please read the Honda
warranty information booklet that came with your vehicle for precise information on
warranty coverages. Your vehi cle’s original tires are covered by their manufacturer.
Tire warranty information is in a separate booklet.
■Statement on Warranty Coverage for Aftermarket and Recycled Parts
The Magnuson-Moss Warranty Act, 15 U.S.C. s.2301 et seq., makes it illegal for motor
vehicle manufacturers to void a motor vehi cle warranty or deny warranty coverage
solely because an aftermarket or recycled part has been used to repair the vehicle or
someone other than the authorized service provider performed service on the vehicle.
This provision does not apply to a new motor vehicle purchased solely for
commercial or industrial use.
Under federal law, a manufacturer may de ny warranty coverage and charge for
repairs to a vehicle if it is discovered that an aftermarket or recycled part installed on
the vehicle is defective or was installed incorrectly and caused damage to another
part of the vehicle otherwise covered under warranty.
The Federal Trade Commission requires th at a manufacturer demonstrate that an
aftermarket or recycled part or servic e performed by a person other than an
authorized service provider caused damage to another part of the vehicle otherwise
covered under warranty before denying warranty coverage.
Additionally, federal law allows a manufactur er to void a motor vehicle warranty or
deny warranty coverage if the manufactur er provides the article or service to
consumers free of charge under the warranty or the manufacturer has secured a
waiver from the Federal Trade Commission.
