General Motors' Commitment to You

We are committed to assure your satisfaction with your new General Motors Medium Duty Truck. Your General Motors Medium Duty dealer also wants you to be completely satisfied and invites you to return for all your service needs, both during and after the warranty period.

You should be aware that not all General Motors Medium Duty Truck dealers are equipped to service all General Motors Medium Duty vehicles. If you are traveling or unable to return to your selling General Motors Medium Duty dealer for any reason, call 1-800-263-3777 (English), 1-800-263-7854 (French) for the name and location of the nearest General Motors Medium Duty Truck service location.

Vehicle Operation and Care

Considering the investment you have made in your new Medium Duty Truck, we know you will want to operate and maintain it properly. We urge you, therefore, to follow the maintenance instructions contained in your Owner's Manual.

If you have any questions on how to keep your vehicle in good working condition, see your General Motors Medium Duty Truck dealer, the place many GM customers choose to have their maintenance work done. You can rely on your General Motors Medium Duty Truck dealer to use proper parts and repair practices.

Maintenance Records

General Motors of Canada Limited recommends that you retain receipts covering performance of regular vehicle maintenance. Repairs required due to damage resulting from lack of maintenance are not covered under your warranty. Receipts can be very important if a question arises as to whether a malfunction is caused by lack of maintenance or a defect in material or workmanship.

We suggest you keep these receipts in the glove box literature portfolio. Also a "Maintenance Record" form is provided in the Owners Manual (Maintenance Schedule section) for your convenience in recording services performed.

Owner Name/Address Change

General Motors encourages all owners to report, at their earliest convenience, a change in name or address by calling our Customer Communication Centre toll free at 1-800-263-3777 (English) or 1-800-263-7854 (French). If you are a subsequent owner, please be sure to advise us by calling the number above. You may also visit the General Motors dealer of your choice to report a change in vehicle ownership. The current owner name and address is essential for General Motors to provide timely notification to owners of important information related to their vehicles.

Owner Assistance

Should you ever encounter a problem during or after the warranty periods that is not resolved, talk to a member of dealer management. Under certain circumstances, GM and/or GM dealers may provide assistance after the limited warranty period has expired when the problem results from a defect in material or workmanship. These instances will be reviewed on a case-by-case basis. If the problem persists, follow the procedures outlined in Owner Assistance .

We thank you for choosing a General Motors Medium Duty Truck product.

Warranty Service -- United States and Canada

Your selling dealership has made a large investment to ensure that they have the proper tools, training, and parts inventory to make any necessary warranty repairs should they be required during the warranty period. We ask that you return to your selling dealer for warranty repairs. In the event of an emergency repair, you may take your vehicle to any authorized GM Medium Duty Truck dealer for warranty repairs. However, certain warranty repairs require special tools or training that only a dealer selling your brand may have. Therefore, not all dealers are able to perform every repair. If a particular dealership cannot assist you, then contact the Customer Assistance Center. If you have changed your residence, visit any GM Medium Duty Truck dealer in the United States or Canada for warranty service. Allison Transmission® service is provided by authorized Allison Transmission® dealers. Diesel engine service for the Isuzu 6H engine can be obtained from Isuzu diesel engine service centers that include most GM Medium Duty dealers. Engine service for the Caterpillar® C7 engine may be obtained at a Caterpillar® Engine dealer. In case you require assistance in locating a dealer to perform service on your GM Medium Duty Truck, refer to the toll-free telephone numbers under "Customer Assistance Offices" under Owner Assistance for more information.
