Anti-lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, this warning light on
the instrument panel will come on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.Let’s say the road is wet and you’re driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here’s what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel. United States

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signalasher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel willash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel willash 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 gearbeforeyou 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.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer, you may want to drive in
THIRD (3) instead of AUTOMATIC OVERDRIVE (
X).
Shift to a lower gear as needed.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with 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
PARK (P) yet.
2. Have someone place chocks under the trailer’s
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and shift to PARK (P).
5. Release the regular brakes.

CAUTION: (Continued)

Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind
noise and affect windshield washer performance. Check
with your dealer before adding equipment to the
outside of your vehicle.
Fuel
The 8th digit of your vehicle identification number (VIN)
shows the code letter or number that identifies your
engine. You will find the VIN at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 5-85.
Gasoline Octane
If your vehicle has the 3800 V6 engine (VIN Code K),
use regular unleaded gasoline with a posted octane
of 87 or higher. If the octane is less than 87, you may
get a heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or higer as
soon as possible. Otherwise, you might damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher-octane fuel is
necessary. If you are using 87 octane or higher-octane
fuel and you hear heavy knocking, your engine
needs service.
If your vehicle has the 3800 Supercharged V6 engine
(VIN Code 1), use only premium unleaded gasoline with
a posted octane of 91 or higher. In an emergency,
you may be able to use a lower octane — as low as
87 — if heavy knocking does not occur. Refill your tank
with premium fuel as soon as possible. Otherwise,
you might damage your engine. If you are using
91 octane or higher-octane fuel and you hear heavy
knocking, your engine needs service.

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
overow tube on the radiatorller neck.
The radiator pressure cap is located near the front of
the engine compartment on the passenger’s side of the
vehicle.
SeeEngine Compartment Overview on page 5-10for
more information on location.
Engine Overheating
You willfind a coolant temperature gage and a hot
engine warning light on your instrument panel.
SeeEngine Coolant Temperature Gage on page 3-34
andEngine Coolant Temperature Warning Light on
page 3-34.
Overheated Engine Protection
Operating Mode
The overheated engine protection operating mode
allows your vehicle to be driven to a safe place in an
emergency situation. If an overheated engine condition
exists, this mode, which alternatesfiring 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 overheated engine condition exists. Driving extended
miles (km) and/or towing a trailer in the overheated
engine protection operating 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.

Tire Pressure Monitor System
If your vehicle has the tire inflation monitor system, it
can alert you to a large change in the pressure of
one tire. The system“learns”the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 45 and 90 minutes
of driving to learn the tire pressures. This time may
be longer depending on your individual driving habits.
Learning need not be accumulated during a single
trip. Once learned, the system will remember the tire
pressures until the system is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire inflation monitor system
won’t alert you if the pressure in more than one tire is low,
if the system is not properly calibrated, or if the vehicle is
moving faster than 70 mph (110 km/h).
The tire inflation monitor system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a low
tire—but it doesn’t replace normal tire maintenance.
SeeTires on page 5-56.When the LOW TIRE light comes on, you should stop
as soon as you can and check all your tires for damage.
(If a tire isflat, seeIf a Tire Goes Flat on page 5-66.)
Also check the tire pressure in all four tires as soon as
you can. SeeInflation—Tire Pressure on page 5-57.
The LOW TIRE light will also be displayed (while
the ignition is on) until you reset (calibrate) the system.
Don’t reset the tire inflation monitor system without
first correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you
reset the system when the tire pressures are incorrect,
the system will not work properly and may not alert
you when a tire is low.
Any time you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire inflation monitor system.
You’ll also need to reset the system whenever you
buy new tires and whenever the vehicle’s battery has
been disconnected.
To reset (calibrate) the system:
1. Turn the ignition to RUN.
2. Locate the red RESET button inside of your
instrument panel fuse block.
The fuse block is located under the cover labeled
FUSES, which is at the end of the instrument panel
on the passenger’s side of the vehicle. The
RESET button is thefirst button in the top row of
the fuse block.

Top of the Instrument Panel
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
surfacefinish.
Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dustfilms on interior glass. See
GM Vehicle Care/Appearance Materials on page 5-84.
Notice:Don’t use abrasive cleaners on glass,
because they may cause scratches. Avoid placing
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.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do, 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.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. SeePart D: Recommended
Fluids and Lubricants on page 6-16.

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 1-54.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood fuse block. 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
system checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a 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, have
itfixed.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel fuse block
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 isfixed.
