FM Stereo
FM stereo gives the best sound, but FM signals
only reach about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels could cause
loss of the XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Care of Your CDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a CD is
damaged, such as cracked, broken, or scratched,
the CD does not play properly or not at all. If the
surface of a CD is soiled, take a soft, lint free cloth
or dampen a clean, soft cloth in a mild, neutral
detergent solution mixed with water, and clean it.
Make sure the wiping process starts from the center
to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.
Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.

{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 390.
When replacing the fuel cap, turn it clockwise
until it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.
This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp
on page 185.The TIGHTEN GAS CAP message will be
displayed on the Driver Information Center (DIC) if
the fuel cap is not properly installed. SeeDIC
Warnings and Messages on page 199for more
information.
{CAUTION:
If a re starts while you are refueling, do
not remove the nozzle. Shut off the ow
of fuel by shutting off the pump or by
notifying the station attendant. Leave the
area immediately.
Notice:If you need a new fuel cap, be sure
to get the right type. Your dealer/retailer
can get one for you. If you get the wrong type,
it may not t properly. This may cause your
malfunction indicator lamp to light and
may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp
on page 185.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Whenever the oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change the
oil prior to a CHANGE ENGINE OIL SOON
message being turned on, reset the system.
Always reset the engine oil life to 100% after every
oil change. It will not reset itself. To reset the
Engine Oil Life System:
1. Display the OIL LIFE REMAINING on the DIC.
2. Press and hold the SET/RESET button on the
DIC for more than ve seconds. The oil life
will change to 100%.
If the CHANGE ENGINE OIL SOON message
comes back on when you start your vehicle, the
Engine Oil Life System has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that can
be unhealthy for your skin and could even cause
cancer. Do not let used oil stay on your skin for very
long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine
oil. See the manufacturer’s warnings about the use
and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil
from the lter before disposal. Never dispose of oil
by putting it in the trash, pouring it on the
ground, into sewers, or into streams or bodies of
water. Instead, recycle it by taking it to a place
that collects used oil. If you have a problem
properly disposing of used oil, ask your
dealer/retailer, a service station, or a local
recycling center for help.

{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
Occasionally check the coolant level in the
radiator. For information on how to add coolant to
the radiator, seeCooling System on page 326.
Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 306
for more information on location.
Engine Overheating
There is a coolant temperature gage and a
warning light on the instrument panel that indicate
an overheated engine condition. SeeEngine
Coolant Temperature Gage on page 184
andEngine Coolant Temperature Warning Light
on page 183.
In addition, you will nd an ENGINE
OVERHEATED IDLE ENGINE and an ENGINE
OVERHEATED STOP ENGINE message
displayed on the vehicle’s Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 199for more information.

Windshield Washer Fluid
What to Use
When you need windshield washer uid, be sure to
read the manufacturer’s instructions before use. If
you will be operating your vehicle in an area where
the temperature may fall below freezing, use a uid
that has sufficient protection against freezing.
Adding Washer Fluid
A WASHER FLUID LOW ADD FLUID message will
be displayed on the Driver Information Center (DIC)
when you need to add windshield washer uid to
your vehicle. SeeDIC Warnings and Messages on
page 199for more information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full.
SeeEngine Compartment Overview on page 306
for more information on location.Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill the washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.

How to Check
Use a good quality pocket-type gage to check
tire pressure. You cannot tell if your tires are
properly inated simply by looking at them. Radial
tires may look properly inated even when they
are under-inated. Check the tire’s ination
pressure when the tires are cold. Cold means your
vehicle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem.
Press the tire gage rmly onto the valve to
get a pressure measurement. If the cold tire
ination pressure matches the recommended
pressure on the Tire and Loading Information
label, no further adjustment is necessary. If the
ination pressure is low, add air until you reach the
recommended amount.
If you overll the tire, release air by pushing on
the metal stem in the center of the tire valve.
Re-check the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted onto each tire and wheel assembly,
except for the spare tire. The TPMS sensors
monitor the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a message to check
the pressure in a specic tire will appear on the
Driver Information Center (DIC) display. The
low tire pressure warning symbol on the instrument
panel cluster and the CHECK TIRE PRESSURE
message will appear at each ignition cycle until the
tires are inated to the correct ination pressure.
Using the DIC, tire pressure levels can be
viewed by the driver. For additional information
and details about the DIC operation and displays
seeDIC Operation and Displays on page 191
andDIC Warnings and Messages on page 199.

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will ash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low
tire pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct ination
pressure for your vehicle’s tires when theyare cold. SeeLoading Your Vehicle on page 277,
for an example of the Tire and Loading
Information label and its location on your vehicle.
Also seeInation - Tire Pressure on page 359.
Your vehicle’s TPMS system can warn you about
a low tire pressure condition but it does not
replace normal tire maintenance. SeeTire
Inspection and Rotation on page 364andTires on
page 351.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
If the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM will be shown on the DIC
display. If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message will be displayed. Once you re-install the
TPMS sensors, the error message should go
off. See your GM dealer for service if all TPMS
sensors are installed and the error message
comes on and stays on.
362

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires,
the identication codes will need to be matched
to the new tire/wheel position. The sensors
are matched, to the tire/wheel positions, in the
following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and
driver’s side rear tire using a TPMS diagnostic
tool. See your GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You will have two minutes to match each tire
and wheel position. If it takes longer than
two minutes to match any tire and wheel position,
the matching process stops and you will need
to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the LEARN TIRE POSITIONS
message displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate the receiver is ready, and
the TIRE LEARNING ACTIVE message
will display. The TPMS system is ready for
the sensor matching process to begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds.
The horn chirp, which may take up to
30 seconds to sound, conrms that the sensor
identication code has been matched to the
tire/wheel position. To decrease the tire’s
air-pressure use the pointed end of the valve
cap, a pencil-style air pressure gage, or a key.
