The services shown in this schedule up to 100,000 miles (1 66 000 km) should be performed after 100,000 miles (166 000 km) at the same intervals. Footnotes j- The U.S. Environmental Protection Agency or the

California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

# Lubricate the front suspension, kingpin bushings,

steering linkage, transmission shift linkage, transfer case shift linkage, parking brake cable guides, rear driveline center splines, front axle propshaft splines and brake pedal springs. Ball joints and kingpin bushings should not be lubricated unless their temperature is 10°F (- 12°C) or higher, or they could be damaged.

‘k‘k Drive axle service:

Locking Differential -- Drain fluid and refill at first engine oil change. At subsequent oil changes, check fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000.km). Standard Differential -- Check fluid level and add fluid as needed at every engine oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km). More frequent lubrication may be required for heavy-duty or off-road use. 3500 HD Models with applications requiring extreme overloadtrailer towing conditions and high-speed (above 45 mph or 70 k m h ) conditions for extended periods of time must have the drive axle fluid changed every 30,000 miles (50 000 km).

Courtesy Transportation GMC Truck 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, dues 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 five day maximum.

All Courtesy Transportation arrangements will be administered by your GMC Truck dealership service management. All requests should reflect actual costs up to and not to exceed the maximum allowable dollar limits. Some state insurance regulations make it impractical to rent vehicles to people under 21 years of age. If you are under 2 1 and have difficulty renting a vehicle, GMC Truck 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 Truck 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 Truck dealer.

GM Participation in BBB AUTO LINE -- Alternative Dispute Resolution Program* *This program may not be available in all states, depending on state law. Canadian owners refer to your Warranty and Owner Assistance Information booklet. General Motors reserves the right to change eligibility limitations and/or to discontinue its participation in this program. Both GMC Truck and your GMC Truck 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 Truck voluntarily participates in BBB AUTO LINE.

BBB AUTO LINE is an out-of-court program administered by the Better Business Bureau system to settle disputes b.etween customers and automobile manufacturers. 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 4200 Wilson Boulevard Suite 800 Arlington, VA 22203 Telephone: 1-800-955-5 100

To file a claim, you will be asked to provide your name and address, your Vehicle Identification Number (VIN) and a statement of the nature of your complaint. Eligibility is limited by vehicle age and mileage, and other factors. We prefer you utilize the Customer Satisfaction 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 between you and GMC Truck. If this mediation is unsuccessful, 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 be bound by that decision. The entire dispute resolution procedure should ordinarily take about 40 days from the 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 1-800-955-5 100 or the GMC Truck Customer Assistance Center at 1 -800-GMC-TRUCK (1-800-442-8782).

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 Administration (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 in 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.

Service Manuals Service manuals contain diagnostic and repair information for all chassis and body systems. They may be useful for owners who wish to get a greater understanding of their vehicle. They are also useful for owners with the appropriate skill level or training who wish to perform “do-it-yourself’ service. These are authentic General Motors service manuals meant for professional, qualified technicians. Service Bulletins Service bulletins covering various subjects are regularly sent to all General Motors dealerships. GM monitors product performance in the field. When service methods are found which promote better service on GM vehicles, bulletins are created to help the technician perform better service. Service bulletins may involve any

number of vehicles. Some will describe inexpensive service; others will describe expensive service. Some will advise of new or unexpected conditions, and others may help avoid future costly repairs. Service bulletins are meant for qualified technicians. In some cases bulletins refer to service manuals, specialized tools, equipment and safety procedures necessary to service the vehicle. Since these bulletins are issued throughout the model year and beyond, an index is required and published quarterly to help identify specific bulletins. Subscriptions are available. You can order an index at the toll-free numbers listed previously, or ask a GM dealer to see an index or individual bulletin. Owner Publications Owner’s manuals, warranty folders and various owner assistance booklets provide owners with general operation and maintenance information.
