Care of Your CD and DVD Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics
with lubricants internal to the CD mechanism.
Cleaning the Video Screen
Pour some isopropyl or rubbing alcohol on a clean cloth
and gently wipe the video screen. Do not spray
directly onto the screen and do not press too hard or
too long on the video screen.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. If the mast should ever
become slightly bent, you can straighten it out by hand.
If the mast is badly bent, as it might be by vandals,
you should replace it.
Check occasionally to be sure the mast is still tightened
to the cowl. If tightening is required, tighten by hand,
then with a wrench one quarter turn.
XM™ Satellite Radio Antenna
System (48 Contiguous US States)
Your XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
The performance of your XM™ system may be affected
if your sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of your XM™ system. Make
sure that the XM™ satellite antenna is not obstructed.
Chime Level Adjustment
The radio is the vehicle chime producer. To change the
volume level, press and hold pushbutton 6 with the
ignition on and the radio power off. The chime volume
level will change from the normal level to loud, and LOUD
will appear on the display. To change back to the default
or normal setting, press and hold pushbutton 6 again.
The chime level will change from the loud level to normal,
and NORMAL will appear on the display. Each time the
chime volume is changed, three chimes will sound as an
example of the new volume selected. Removing the radio
and not replacing it with a factory radio or chime module
will disable vehicle chimes.

1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other. If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved in
the jump start procedure. Put the automatic
transmission in PARK (P) before setting the parking
brake. If you have a four-wheel-drive vehicle, be
sure the transfer case is in a drive gear not in
NEUTRAL.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlets. Turn off
the radio and all the lamps that aren’t needed. This
will avoid sparks and help save both batteries.
And it could save your radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations of the other vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−) jump
starting terminal. You should always use these
remote terminals instead of the terminals on the
battery.
The remote positive (+) terminal is located behind a
red plastic cover, if equipped, near the engine
accessory drive bracket. To uncover the remote
positive (+) terminal, open the red plastic cover, if
equipped.
The remote negative (−) terminal is located on the
engine drive bracket, or on the thermostat
housing on the 8.1L engine. It is marked″GND.″
SeeEngine Compartment Overview on page 5-12
for more information on location.

Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels. If
your vehicle has this feature, sensors are mounted
on each tire and wheel assembly, except the spare tire.
The TPM sensors transmit tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition is detected, the TPM
system will display the CHECK TIRE PRESSURE
warning message on the Driver Information Center
(DIC); and at the same time illuminate the low tire
pressure warning symbol. For additional information and
details about the DIC operation and displays see DIC
Operation and Displays on page 3-58andDIC Warnings
and Messages on page 3-70.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is signicantly
under-inated.
You should stop and check your tires as soon as
possible, and inate them to the proper pressure as
indicated on the vehicle’s tire information placard.Driving on a signicantly under-inated tire causes the
tire to overheat and can lead to tire failure.
Under-ination also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability. Each tire, including the spare, should be
checked monthly when cold and set to the
recommended ination pressure as specied in the
vehicle placard and owner’s manual.
The Certication/Tire label or the Tire and Loading
Information label (tire information placard) shows the
size of your vehicle’s original tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeInation - Tire Pressure on page 5-72. For
the location of the tire and loading information label, see
Loading Your Vehicle on page 4-56.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-76andTires on page 5-63.
Notice:Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.

6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in step 5.
9. After hearing the conrming horn chirp for the left
rear tire, check to see if the TPM warning light is
still ashing. If yes, turn the ignition switch to OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Certication/Tire label or
the Tire and Loading Information label.
11. Put the valve caps back on the valve stems
The spare tire does not have a TPM sensor. If you
replace one of the road tires with the spare, the CHECK
TIRE PRESSURE message will be displayed on the
DIC screen. This message should go off once you
re-install the road tire containing the TPM sensor. The
SERVICE TIRE MONITOR message is displayed
when the TPM system is malfunctioning. One or more
missing or inoperable TPM sensors will cause the
service tire monitor message to be displayed. See your
dealer for service.Federal Communications Commission and
Industry and Science Canada

Cleaning the 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 reections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
Cleaning Interior Plastic Components
Use only a mild soap and water solution on a soft cloth
or sponge. Commercial cleaners may affect the
surface nish.
Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dust lms on interior glass. See
Vehicle Care/Appearance Materials on page 5-110.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger and the integrated radio antenna. When
cleaning the glass on your vehicle, use only a soft
cloth and glass cleaner.
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. SeeRecommended
Fluids and Lubricants on page 6-12.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
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 1-86.
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 and not snow, etc., be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers 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 xed or goes away.
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. This greatly reduces the
chance of res caused by electrical problems.
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. 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 correct
amperage. Replace it as soon as you can.
