10-78 Vehicle Care
GM recommends replacing tires in
sets of four. This is because uniform
tread depth on all tires will help
keep the vehicle performing most
like it did when the tires were new.
Replacing less than a full set of
tires can affect the braking and
handling performance of the vehicle.
SeeTire Inspection on page 10‑73
and Tire Rotation on page 10‑73 for
information on proper tire rotation.
{WARNING
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or dismount
the tires.
{WARNING
Mixing tires could cause you
to lose control while driving.
If you mix tires of different sizes,
brands, or types (radial and
bias-belted tires), the vehicle
might not handle properly, and
you could have a crash. Using
tires of different sizes, brands,
or types could also cause
damage to the vehicle. Be sure
to use the same size, brand,
and type of tires on all wheels.
This vehicle may have a different
size spare than the road tires
(those originally installed on the
vehicle). When new, the vehicle
included a spare tire and wheel
assembly with a similar overall
diameter as the vehicle's road
tires and wheels, so it is all right
to drive on it. Because this spare
was developed for use on the
vehicle, it will not affect vehicle
handling.
{WARNING
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace the vehicle's
tires with those that do not have
a TPC Spec number, make sure
they are the same size, load range,
speed rating, and construction type
(radial and bias‐belted tires) as the
vehicle's original tires.

Vehicle Care 10-115
Do not use silicone or wax-based
products, or those containing
organic solvents to clean the
interior because they can alter
the appearance by increasing the
gloss in a non-uniform manner.
Instrument Panel, Vinyl and
other Plastic Surfaces
To remove dust, a soft cloth
dampened with water can be
used. If a more thorough cleaning
is necessary, a clean soft cloth
dampened with a mild soap solution
can be used to gently remove dust
and dirt. Never use spot lifters
or removers on plastic surfaces.
Many commercial cleaners and
coatings that are sold to preserve
and protect soft plastic surfaces
may permanently change the
appearance and feel of the interior
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solventsto clean the interior because they
can alter the appearance by
increasing the gloss in a
non-uniform manner.
Some commercial products may
increase gloss on the instrument
panel. The increase in gloss may
cause annoying reflections in the
windshield and even make it difficult
to see through the windshield under
certain conditions.
Notice::
Air fresheners contain
solvents that may cause damage
to plastics and painted surfaces.
Follow the manufacturer ’s
instructions when using air
fresheners in the vehicle. If air
freshener comes in contact with
paint or a plastic surface, blot
immediately with a soft cloth.
Damage caused by using air
fresheners would not be covered
by the vehicle warrant.
Care of Safety Belts
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them.
In a crash, they might not be able
to provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.

Service and Maintenance 11-7
.Evaporative control system
inspection. Check all fuel and
vapor lines and hoses for proper
hook‐up, routing, and condition.
Check that the purge valve,
if the vehicle has one, works
properly. Replace as needed.
An Emission Control Service.
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.First Engine Oil Change After
Every 160 000 km/100,000 Miles
.Automatic transmission fluid
change (normal service).
See
Automatic Transmission
Fluid (4-Speed Transmission) on
page 10‑13 orAutomatic
Transmission Fluid (6-Speed
Transmission) on page 10‑16.
.Four‐wheel drive only: Transfer
case fluid change (normal
service). Check vent hose at
transfer case for kinks and
proper installation. Check to be
sure vent hose is unobstructed,
clear, and free of debris. During
any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
output seals. High pressure
water can overcome the seals and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.
.Spark plug replacement and
spark plug wires inspection.
An Emission Control Service.
First Engine Oil Change After

.Engine cooling system drain,
flush, and refill (or every five
years, whichever occurs first).

Vehicle Data
Recording and
Privacy
This GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, the vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash, and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help the dealer technician
service the vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio pre-sets, seat positions,
and temperature settings.
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment or
hitting a road obstacle, data that
will assist in understanding how
a vehicle's systems performed.
The EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period of
time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
.How various systems in the
vehicle were operating.
.Whether or not the driver and
passenger safety belts were
buckled/fastened.
.How far, if at all, the driver was
pressing the accelerator and/or
brake pedal.
.How fast the vehicle was
traveling.
