press the TCS button
located on the instrument
panel switchbank.
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver.
If the front drive wheels begin
to slip, the rear wheels will automatically begin to
drive the vehicle as required. There may be a slight
engagement noise during hard use but this is normal.
During heavy
AWD applications, the engine torque
may be reduced to protect AWD system components.
If the vehicle is exposed to extended heavy AWD usage,
the AWD system will shut itself
off to protect the system
from overheatinq. When the system
cools down, the
AWD system will activate itself again automatically; this

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring.
The arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you’re about
to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even
if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not.
It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
If you are towing a trailer that weighs more than
1,000 Ibs. (450 kg), you may prefer to drive in THIRD (3)
instead of AUTOMATIC OVERDRIVE (D) (or, as you
need
to, a lower gear). This will minimize heat build-up
and extend the life of your transaxle.
Parking on Hills
I
You really should not park your vehicle, u....~ a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can be injured, and both your vehicle and the
trailer can be damaged.
But
if you ever have to park your rig on a hill,
here’s how to do it:
1. Apply your regular brakes, but don’t shift into
2, Have someone place chocks under the trailer

wheels. regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift
to PARK (P).
5. Release the regular brakes.

L
Things that burn can get on hot engine parts
and start
a fire. These include liquids like fuel,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that
will burn onto a hot engine.
1. Pull the hood release handle, located on the
driver's side under the instrument panel.
2. Go to the front of the vehicle and push up on the
underhood release, located near the center under
the grille.

Radiator Pressure Cap
Notice: Your radiator cap is a pressure-type cap
and must be tightly installed to prevent coolant
loss
and possible engine damage from overheating.
Be sure the arrows on the cap line
up with the
overflow tube on the radiator filler neck.
The radiator pressure cap is located at the front of the
engine compartment on the passenger’s side of the
vehicle. See
Engine Compartment Overview on
page 5-72 for more information on location.
Engine Overheating
You will find an engine coolant temperature gage on
your vehicle’s instrument panel cluster. See
Engine
Coolant Temperature Gage
on page 3-47. You also
have an engine coolant temperature warning message
on your instrument panel. See
Engine Coolant
Temperature Warning Message
on page 3-53.
Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates firing groups of
cylinders helps prevent engine damage.
In this mode,
you will notice a significant
loss in power and engine
performance. The temperature gage will indicate
an overheat condition exists. Driving extended miles
(km) and/or towing a trailer in the overheat protection
mode should be avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair. The engine oil will be severely degraded.
Repair the cause
of coolant loss, change the oil
and reset the
oil life system. See “Engine Oil” in
the Index.

Vinyl Top of the Instrument Panel
Use warm water and a clean cloth.
e Rub with a clean, damp cloth to remove dirt.
You may have to do this more than once.
Things like tar, asphalt and shoe polish will stain if
you don't get them off quickly. Use a clean cloth
and vinyl/leather cleaner. See your dealer for
this product.
Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe
dry with a soft cloth. Then, let
the leather dry naturally.
Do not use heat to dry.
For stubborn stains, use a leather cleaner. See your
dealer for this product.
0 Never use oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish
on leather. Use
only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying reflections in the
windshield and even make it difficult
to see through
the windshield under certain conditions.
Interior Plastic Components
Use only a mild soap and water solution on a soft cloth
or sponge. Commercial cleaners may affect the
surface finish.
Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or
a liquid household glass cleaner will remove normal
tobacco smoke and dust films on interior glass.
See
GM Vehicle CardAppearance Materials on
page 5-93.
Notice: Don't use abrasive cleaners on glass,
because they may cawe s~~ratches. bvnIc! p!scing
decals on the inside rear window, since they
may have to be scraped
off later. If abrasive
cleaners are used on the inside
of the rear window,
an electric defogger element may be damaged.
Any temporary license should not be attached
across
the defogger grid.

Vehicle Identification
Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears
on a plate in the front corner of the instrument panel,
on the driver’s side. You can see it if you
look through
the windshield from outside your vehicle. The VIN
also appears on the Vehicle Certification and Service
Parts labels and the certificates of title and registration.

Electrical System
Add-on Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment can
keep other components from working as they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see
Servicing
Your Air Bag-Equipped Vehicle
on page 1-76.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go on and
off, or in
some cases to remain
off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to get it fixed.
Power Windows and Other
Power Options
Circuit breakers in the instrument panel fuse panel
protect the power windows and other power accessories.
When the current load is too heavy, the circuit breaker
opens and closes, protecting the circuit until the
problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one
of the identical
size and rating.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage or use one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can get along without
- like the radio
or cigarette lighter
- and use its fuse, if it is the
right amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle, the instrument
panel fuse block and the underhood fuse block.
