GM Service Manual Online
For 1990-2009 cars only

General Motors of Canada Limited warrants to owners of passenger cars, light duty trucks and vans sold in Canada, that the vehicle (1) was designed, built and equipped so as to conform at the time of sale with the Emission Regulations under the Canadian Environmental Protection Act and (2) is free from defects in material and workmanship which cause the vehicle to fail to conform with those regulations for a period of the coverage outlined below.

How to Determine the Applicable Emission Control System Warranty

Federal or provincial agencies may require different emission control system warranties for light duty trucks depending on whether the truck is certified with a light duty or heavy duty emission control system.

Do the following to determine emission eligibility:

  1. Determine if the vehicle is equipped with a gasoline or diesel engine.
  2. Locate the underhood emission control label located inside the engine compartment on the air cleaner assembly or the engine.
  3. The language on the bottom left side of the label will describe if the vehicle is equipped with a light or heavy duty emissions control system.

Emission Control Warranty

The Emission Control Systems Warranty period described below shall begin on the date the vehicle is first delivered to the first retail purchaser or, on the date the vehicle is first placed in service as a demonstrator or company vehicle prior to sale at retail. Emission related defects in the genuine GM components including related diagnostic costs, parts and labour, are covered by this warranty.

    • Passenger Cars, Light Duty Trucks (A Gross Vehicle Weight Rating (GVWR) of 3856 kg (8500 lbs) or less) and Vans Equipped with Light Duty Gasoline Engine
       - For Chevrolet, Pontiac, and GMC, 3 year or 60 000 kilometres whichever comes first; for Buick and Hummer, 4 year or 80 000 kilometres whichever comes first on the Components in the Emission Control Systems Warranty Parts List; and 8 years or 130 000 kilometres, whichever comes first, on the Specified Major Emission Components.
    • Light Duty Truck (A Gross Vehicle Weight Rating (GVWR) of 3856 kg (8500 lbs) or greater) Equipped with Heavy Duty Gasoline Engine
       - 5 years or 80 000 kilometres, whichever comes first.
    • Light Duty Truck (A Gross Vehicle Weight Rating (GVWR) of 3856 kg (8500 lbs) or greater) Equipped with Heavy Duty Diesel Engine
       - 5 years or 80 000 kilometres, whichever comes first.

Emission Performance

Some provinces and local jurisdictions have established periodic vehicle Inspection and Maintenance (I/M) programs to encourage proper maintenance of your vehicle. If a provincial I/M program is enforced in your area you may also be eligible for Emission Performance coverage when all of the following three conditions are met:

  1. The vehicle has been maintained and operated in accordance with the instructions for proper maintenance and use set forth in the Owner Manual and the New Vehicle Limited Warranty, Maintenance and Owner Assistance Information booklet supplied with your vehicle;
  2. The vehicle fails a provincial I/M test during the emission warranty period indicated above; and
  3. The failure results, or will result, in the owner of the vehicle having to bear a penalty or other sanctions (including the denial of the right to use the vehicle) under local, provincial, or federal law.

General Motors of Canada Limited warrants that your dealer will replace, repair, or adjust to GM specifications, at no charge to you, any of the parts listed under the "Emission Warranty Parts List" later in this section which may be necessary to conform to the applicable emission standards. Non-GM parts labelled "Certified to EPA Standards" are covered by the Federal Emission Performance Warranty.

Claims Procedure

Make your vehicle available to any authorized GM dealer as soon as possible after failing a provincial I/M test or at any time you suspect a defect in a part. If all the above conditions are met, GM warrants that your dealer will replace, repair, or adjust to GM specifications, at no charge to you, any of the parts listed under "Emission Control Systems Warranty Parts List" which may be necessary to cause your vehicle to conform to the applicable emission standards.

Repairs which do not qualify will be charged to you.

In the event a warranty matter is not handled to your satisfaction, refer to the Customer Satisfaction Procedure in this booklet under Owner Assistance .
