Exhaust System Inspection Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts a s well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle. See ”Engine Exhaust” in the Index. Engine Cooling System Inspection Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year. Throttle System Inspection Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator and cruise control cables.

CMC dealers have the facilities, trained technicians and up-to-date information to promptly address any concerns you may have. However, if a concern has not been resolved to your complete satisfaction, take the following steps: STEP ONE -- Discuss your concern with a member of dealership management.

If the matter has already been reviewed with the sales, service or parts manager, contact the owner of the dealership or the general manager.

Courtesy Transportation GMC Commitment Plus offers courtesy transportation for customers when obtaining warranty service. This program is offered in conjunction with the 3 year/36,000 mile (60 000 km) Bumper to Bumper New Vehicle Limited Warranty. Courtesy transportation includes:

One way shuttle ride from the dealership (up to 10 miles (16 km)) for same-day warranty repairs. A loaner vehicle will be made available for overnight warranty repairs up to a five day maximum, or up to a $30 allowance for a rental vehicle, cab, bus or other transportation in lieu of a loaner. (Bringing vehicles in late in the day, for service on the next day. c10c.s not constitute overnight repairs.) Gas allowance of up to $10 a day for rides provided by another person (i.e., friend, neighbor, etc.) in lieu of rental for overnight warranty repair up to a five day maximum.

8-8

Some state insurance regulations make it impractical to rent vehicles to people under 2 1 years of age. If you are under 2 1 and have difficulty renting a vehicle, GMC will reimburse up to $30/day for documented transportation you receive. The Commitment Plus Courtesy Transportation Program is not part of the Bumper to Bumper Limited Warranty. GMC reserves the right to make any changes or discontinue the Courtesy Transportation Program at any time without notification. For additional program details, contact your GMC dealer. In Canada, please consult your GM dealer for information on Courtesy Transportation.

GM Participation in an Alternative Dispute Resolution Program This program is available in all 50 states and the District of Columbia. Canadian owners refer to your Warranty and Owoer Assistance Information booklet for information on the Canadian Motor Vehicle Arbitration Plan (CAMVAP). General Motors reserves the right to change eligibility limitations and/or to discontinue its participation in this program. Both GMC and your GMC dealer are committed to making sure you are completely satisfied with your new vehicle. Our experience has shown that, if a situation arises where you feel your concern has not been adequately addressed, the Customer Satisfaction Procedure described earlier in this section is very successful. There may be instances where an impartial third party can assist in arriving at a solution to a disagreement regarding vehicle repairs or interpretation of the New Vehicle Limited Warranty. To assist in resolving these disagreements, GMC voluntarily participates in BBB AUTO LINE.

BBB AUTO LINE is an out-of-court program administered by the Better Business Bureau system to settle automotive disputes. This program is available free of charge to customers who currently own or lease a GM vehicle. If you are not satisfied after following the Customer Satisfaction Procedure, you may contact the BBB using the toll-free telephone number, or write them at the following address:

BBB AUTO LINE Council of Better Business Bureaus, Inc. 4200 Wilson Boulevard Suite 800 Arlington, VA 22203- 1804 Telephone: 1-800-955-5 100

To file a claim, you will be asked to provide your name and address, YOLK Vehicle Identification Number (VIN) and a statement of the nature of your complaint. Eligibility is limited by vehicle age and mileage, and other factors.

8-9

We prefer you utilize the Customer Satisfxtion Procedure before you resort to AUTO LINE, but you may contact the BBB at any time. The BBB will attempt to resolve the complaint serving as an intermediary. If this mediation is unsuccessf~~l, an informal hearing will be scheduled where eligible customers may present their case to an impartial third-party arbitrator. The arbitrator will make a decision which you may accept or reject. If you accept the decision, GM will 1 bound by that decision. The entire dispute resolution procedure should ordinarily take about 40 days from time you file a claim until a decision is made. Some state laws may require you to use this program before filing a claim with a state-run arbitration program or in the courts. For further information, contact the BBB at 1-800-955-5 IO0 or the GMC Customer Assistance Center at 1 -800-GMC-8782 (1 -800-462-8782). Warranty Information Your vehicle comes with a separate warranty booklet that contains detailed warranty information.

REPORTING SAFETY DEFECTS TO THE UNITED STATES GOVERNMENT If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Adtninistration (NHTSA), in addition to notifying General Motors. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved i n individual problems between you, your dealer or General Motors. To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-800-424-9393 (or 366-0123 in the Washington, D.C. area) or write to:

NHTSA, U.S. Department of Transportation Washington, D.C. 20590

You can also obtain other information about motor vehicle safety from the Hotline.
