Passenger Compartment Air Filter
The filter is located under the instrument panel below
the glove compartment.
To replace the passenger compartment air filter do
the following:
1. Remove the bolts on the access panel and set the
panel aside. Because this operation can be a little
difficult, you may choose to have it done at your
dealer's service department.
2. Reach under the
instrument panel
towards the front of
the vehicle and pull
down on the filter
retaining bracket.
3. Remove the air filter by pulling down on the
element. Remove the second portion of the air filter
by sliding it towards the rear of the vehicle and then
pulling downward.4. Install the new filter by reversing the steps listed
previously. Be sure to follow any instructions that
may be included in the replacement filter package.
Refer to the Maintenance Schedule to determine when
to replace the passenger compartment air filter. See
ªScheduled Maintenanceº in the Index.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one
or more of these conditions:

In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.

In hilly or mountainous terrain.

When doing frequent trailer towing.

Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of
these conditions, change the fluid and filter
every 100,000 miles (166 000 km).
See ªScheduled Maintenance Servicesº in the Index.

6-42 Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See ªWhen It's Time for New Tiresº and
ªWheel Replacementº later in this section for more
information. Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench to tighten the cable. See
ªStoring a Flat or Spare Tire and Toolsº in the Index.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See ªScheduled
Maintenance Servicesº in the Index for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here. Don't include the spare tire in your
tire rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Certification/Tire label. Make certain that all wheel
nuts are properly tightened. See ªWheel Nut Torqueº in
the Index.

be dangerous. In trying to do some jobs, you can

You may use your vehicle in making deliveries.
Or you may drive it to work, to do errands or in
many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep your vehicle in good

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.

8-8
Courtesy Transportation
GMC has always exemplified quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealers are proud
to offer Courtesy Transportation, a customer support
program for new vehicles.
The Courtesy Transportation program is offered to
retail purchase/lease customers in conjunction with
the Bumper
-to-Bumper coverage provided by the
New Vehicle Limited Warranty. Several transportation
options are available when warranty repairs are
required. This will reduce your inconvenience during
warranty repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising your
service consultant of your transportation needs, your
dealer can help minimize your inconvenience. If your
vehicle cannot be scheduled into the service department
immediately, keep driving it until it can be scheduled for
service, unless, of course, the problem is safety
-related.
If it is, please call your dealership, let them know this,
and ask for instructions.If the dealer requests that you simply drop the vehicle
off for service, you are urged to do so as early in the
work day as possible to allow for same day repair.
Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait GMC helps
minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide you with shuttle service
to get you to your destination with minimal interruption
of your daily schedule. This includes a one way shuttle ride
to a destination up to 10 miles from the dealership.
Public Transportation or Fuel Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement up to $30 per day (five days maximum)
may be available for the use of public transportation
such as taxi or bus. In addition, should you
arrange transportation through a friend or relative,
reimbursement for reasonable fuel expenses up to
$10 per day (five day maximum) may be available.
Claim amounts should reflect actual costs and be
supported by original receipts.

8-9
Courtesy Rental Vehicle
When your vehicle is unavailable due to overnight
warranty repairs, your dealer may arrange to provide
you with a courtesy rental vehicle or reimburse you for
a rental vehicle you obtained, at actual cost, up to a
maximum of $30.00 per day supported by receipts.
This requires that you sign and complete a rental
agreement and meet state, local and rental vehicle
provider requirements. Requirements vary and may
include minimum age requirements, insurance coverage,
credit card, etc. You are responsible for fuel usage
charges and may also be responsible for taxes, levies,
usage fees, excessive mileage or rental usage beyond the
completion of the repair.
Generally it is not possible to provide a like
-vehicle as
a courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper
-to-Bumper warranty coverage period,
but it is not part of the New Vehicle Limited Warranty.
A separate booklet entitled ªWarranty and Owner
Assistance Informationº furnished with each new
vehicle provides detailed warranty coverage information.Courtesy Transportation is available only at
participating dealers and all program options, such as
shuttle service, may not be available at every dealer.
Please contact your dealer for specific information about
availability. All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Canadian Vehicles: For warranty repairs during the
Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult your
dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at any time
and to resolve all questions of claim eligibility pursuant to the
terms and conditions described herein at its sole discretion.
Warranty Information
Your vehicle comes with a separate warranty booklet
that contains detailed warranty information.
