7-22 Transfer Case and Front Axle
(All-Wheel Drive) Inspection
Every 12 months or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary. A fluid loss could indicate a problem;
check and have it repaired, if needed. Check vent hose
at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook
-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and
rotors for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. You may need to
have your brakes inspected more often if your driving
habits or conditions result in frequent braking.

Customer Satisfaction ProcedureYour 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.
Sometimes, however, despite the best intentions of
all concerned, misunderstandings can occur. If your
concern has not been resolved to your satisfaction,
the following steps should be taken:
STEP ONE -- Discuss your concern with a member
of dealership management. Normally, concerns can
be quickly resolved at that level. If the matter has
already been reviewed with the sales, service or parts
manager, contact the owner of the dealership or the
general manager.

8-3
STEP TWO -- If after contacting a member of
dealership management, it appears your concern
cannot be resolved by the dealership without further
help, contact the GMC Consumer Relations Manager by
calling 1-800-GMC-8782 (1-800-462-8782, Customer
Assistance prompt). In Canada, contact GM of Canada
Customer Communication Centre in Oshawa by calling
1-800-263-3777 (English) or 1-800-263-7854 (French).
We encourage you to call the toll-free number in order
to give your inquiry prompt attention. Please have the
following information available to give the Customer
Assistance Representative:

Vehicle Identification Number (This is available
from the vehicle registration or title, or the plate
at the top left of the instrument panel and visible
through the windshield.)

Dealership name and location

Vehicle delivery date and present mileageWhen contacting GMC, please remember that your
concern will likely be resolved at a dealer's facility.
That is why we suggest you follow Step One first
if you have a concern.
STEP THREE -- Both General Motors and
your dealer are committed to making sure you are
completely satisfied with your new vehicle. However,
if you continue to remain unsatisfied after following
the procedure outlined in Steps One and Two, you
should file with the GM/BBB Auto Line Program to
enforce any additional rights you may have. Canadian
owners refer to your Warranty and Owner Assistance
Information booklet for information on the Canadian
Motor Vehicle Arbitration Plan (CAMVAP).
