Whenever warranty repairs are required, several transportation options and/or reimbursement of certain transportation expenses are available for your convenience at participating dealers/retailers.

ANSWER: The bumper-to-bumper New Vehicle Limited Warranty covers vehicles registered in the U.S. and Canada from the date the vehicle is first delivered until it reaches three years or 36,000 miles (whichever occurs first). It covers the vehicle from bumper to bumper on any vehicle defect related to materials or workmanship.

ANSWER: GMC vehicles are designed and built to resist corrosion. All body and sheet metal components are warranted against rust-through corrosion for 6 years/100,000 miles (whichever comes first). Application of additional rust-inhibiting materials is neither necessary nor required under the Sheet Metal Coverage. GMC makes no recommendations concerning the usefulness or value of such products. Application of after-manufacture rustproofing products may create an environment which reduces the corrosion resistance built into your vehicle. Repairs to correct damage caused by such applications are not covered under your New Vehicle Limited Warranty. See your GMC dealer for terms of this limited warranty.

ANSWER: Your local GMC dealer should be able to assist you in finding the best conversion company to fit your needs and should be able to handle the details of having the conversion done to your vehicle. Go to the GMC Dealer Locator to locate a GMC dealer in your area.

ANSWER: These repairs must be performed by an Authorized GMC dealer, except in an emergency situation when a covered part or a GMC dealer is not reasonably available to the vehicle owner. It's in your best interest to take your GMC vehicle to a GMC dealer for all repairs since they are the most knowledgeable about the particulars of your vehicle.

ANSWER: Your satisfaction and goodwill are important to your dealer and to GMC. Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer's sales or service departments. The first step is to discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. To locate a GMC dealer, please visit the GMC Dealer Locator.

ANSWER: Currently, GMC parts can only be purchased through your local GMC Dealer. However, some GMC retail websites do allow for the purchase of parts from their facilities via their websites. Therefore, please review your local GMC Dealer's websites for this information.

ANSWER: In a frontal or near-frontal impact of sufficient severity, the air bag sensing system detects that the vehicle is suddenly stopping as a result of a crash. The sensing system triggers a release of inflation gas. This gas inflates the air bag. The inflator, air bag, and related hardware are all part of the air bag module packed inside the steering wheel for the driver air bag and in the instrument panel for the right front passenger air bag.

ANSWER: The air bag is designed to inflate in moderate to severe frontal or near-frontal crashes. The air bag will inflate only if the impact speed is above the system's designed "threshold level." If your vehicle goes straight into a wall that doesn't move or deform, the threshold level is about 14 to 18 mph (23 to 29 km/h). The threshold level can vary, however, with specific vehicle design, so that it can be somewhat above or below this range. If your vehicle strikes something that will move or deform, such as a parked car, the threshold level will be higher. Inflation is determined by the angle of the impact and the vehicle's deceleration.

ANSWER: If the vehicle is equipped with seat mounted side impact or roof rail mounted head curtain air bags, those will deploy in a side impact. If the vehicle is equipped with a roll over capable head curtain air bags, a roll over sensor will deploy the head curtain air bags in a roll over incident. The frontal air bags will not deploy in a side impact or roll over, unless there is also a front or front-corner impact of sufficient severity to trigger the frontal airbags. The airbags will not deploy in a rear impact.

ANSWER: Yes! The air bag supplements the protection provided by the shoulder belts. Remember, the air bag is designed to inflate in moderate-to-severe frontal and near-frontal crashes. Safety belts can provide protection in impacts other than frontal and near-frontal collisions.

ANSWER: To learn about the specific items on your vehicle, please refer to Section 1 in your GMC Owner's Manual, "Seats and Restraint Systems." For general information please visit the safety section on the GM website.

ANSWER: There are no specific child restraints that GMC recommends or endorses, but we do have some information that might be helpful to you.

GMC's seats and safety belt systems are designed to accommodate child restraints. However, we cannot be certain that all child restraints will be compatible with GMC vehicles. Our cars conform to SAE (Society of Automotive Engineers) J1819 standard, which is a recommended guideline for automotive safety belt and child restraint compatibility. Therefore, child restraints that conform to this standard will be more compatible with the seats and safety belt systems used in GMC vehicles. Also, your GMC Dealer can install a tether anchor kit (at no charge to you) that will anchor front-facing child seats.

First, we recommend you work with a child-safety seat manufacturer, or a local retail outlet that sells child restraint seats, for possible suggestions on what type of seat would be most appropriate for your needs. You could also take your child restraint to a checkup event or contact a local CPS technician for additional assistance. There are a couple of websites that have some good information on this topic.

Try these:

NHTSA at www.nhtsa.dot.gov

National Safe Kids www.safekids.org

Safety Beltsafe USA www.carseat.org

American Academy of Pediatrics www.aap.org/family/carseatguide.htm

In addition, you might want to try checking with your local hospital, police department and fire department for any information they might have.

Simply depress the parking brake.

ANSWER: GMC has a Roadside Assistance program to aid owners during an emergency and with other services. It is a service³ that comes with each new GMC car, pickup and SUV. Services provided include:

ANSWER: Roadside Assistance is also included for 100,000 miles/5 years (whichever comes first) on all 2007 and 2008 GMC passenger cars and light-duty trucks. For model years prior to 2007, your vehicle is provided Roadside Assistance for the term that matches its bumper-to-bumper warranty. Please refer to the Owner's Manual for the specific warranty on your vehicle.

ANSWER: There is generally no charge for any of the services listed while the vehicle is covered by the complimentary Roadside Assistance service. However, additional charges may be incurred for some services, including towing the vehicle beyond the closest GMC dealer; for non-warranty parts and labor; or for lost key replacements.
