Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that the front wheels are spinning too much
or are beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power by closing the throttle and managing engine spark
to limit wheel spin.
This light will ash when
your traction control
system is limiting
wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. When road conditions allow you to safely
use it again, you may re-engage the cruise control.
SeeCruise Control on page 3-10.When this light is on solid
and either the SERVICE
TRACTION or TRACTION
OFF message is
displayed, the system will
not limit wheel spin.
Adjust your driving accordingly. SeeDIC Warnings and
Messages on page 3-46for more information.
The Traction Control System is automatically enabled
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system enabled. You can turn TCS
off if you ever need to.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your vehicle is stuck in sand, mud,
ice or snow, and you want to “rock” your vehicle
to attempt to free it. It may also be necessary to turn off
the system when driving in extreme off-road conditions
where high wheel spin is required. SeeIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 4-21.
4-6

To turn the system off or
on, press and release this
button located on the
instrument panel.
The DIC will display the appropriate message as
described previously when you press the button.
Traction Control Operation
Traction control limits wheel spin by reducing engine
power to the wheels (engine speed management)
and by applying brakes to each individual wheel
(brake-traction control) as necessary.
The traction control system is enabled automatically
when you start your vehicle, and it will activate and ash
the ESC/TCS light and display the LOW TRACTION
message if it senses either of the front wheels are
spinning or beginning to lose traction while driving. For
more information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-43.
Notice:If you allow the wheel(s) of one axle
to spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC
and/or SERVICE TRACTION messages are
displayed, you could damage the differential.The repairs would not be covered by your warranty.
Reduce engine power and do not spin the wheel(s)
excessively while these lights and this message
are displayed.
Notice:When traction control is turned off, it is
possible to lose traction. If you attempt to shift with
the front wheels spinning with a loss of traction,
it is possible to cause damage to the transmission.
Do not attempt to shift when the front wheels do
not have traction. Damage caused by misuse of the
vehicle is not covered. See your warranty book
for additional information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, you may
notice a reduction in acceleration, or may hear a noise
or vibration. This is normal.
If your vehicle is in cruise control when the system
activates, the ESC/TCS light will ash and the cruise
control will automatically disengage. When road
conditions allow you to use cruise control again,
you may re-engage the cruise control. SeeCruise
Control on page 3-10.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
4-7

Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability
Control (ESC) system which combines antilock brake,
traction and stability control systems and helps the
driver maintain directional control of the vehicle in
most driving conditions.
When you rst start your vehicle and begin to drive away,
the system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h).
If the system fails to turn on or activate, the ESC/TCS
light will be on solid, and the ESC OFF or SERVICE
ESC message will be displayed.
For more information, seeDriver Information
Center (DIC) on page 3-43.This light will ash on the
instrument panel cluster
when the ESC system
is both on and activated.
You may also feel or hear the system working; this
is normal.
When the light is on solid and either the SERVICE ESC
or ESC OFF message is displayed, the system will
not assist the driver in maintaining directional control of
the vehicle. Adjust your driving accordingly. SeeDIC
Warnings and Messages on page 3-46.
The Electronic Stability Control (ESC) system is
automatically enabled whenever you start your vehicle.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, you can turn ESC off if you
ever need to.

While refueling, hang the tethered fuel cap from the
hook on the fuel door.
{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 the fuel before removing the nozzle. Clean
fuel from painted surfaces as soon as possible.
SeeWashing Your Vehicle on page 5-80.
When replacing the fuel cap, turn it to the 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 3-36.If your vehicle has a Driver Information Center (DIC),
the CHECK GAS CAP message displays if the
fuel cap is not properly installed.
{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 3-36.

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 OIL SOON message being turned on,
reset the system.
After changing the engine oil and lter, the system
must be reset. To reset the oil life system:
1. Turn the ignition key to ON/RUN with the
engine off.
2. Fully press and release the accelerator pedal three
times within ve seconds.
If the message is not displayed, the system is reset.
If the CHANGE 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.

3. Fill the coolant surge tank with the proper mixture, to
the FULL COLD mark on the front of the surge tank.
Wait about ve minutes, then check to see if the level
is below the FULL COLD mark. If the level is below
the FULL COLD mark, add additional coolant to bring
the level up to the mark. Repeat this procedure until
the level remains constant at the FULL COLD mark
for at least ve minutes.
4. With the coolant surge tank pressure cap off, start
the engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine cooling fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the FULL COLD mark, add more of the proper
mixture to the coolant surge tank until the level
reaches the FULL COLD mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer/retailer, if necessary.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
When the windshield washer uid reservoir is low,
a LOW WASHER FLUID message displays on
the Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-46for more information.
Open the cap with the
washer symbol on it.
Add washer uid until the
tank is full. SeeEngine
Compartment Overview
on page 5-14for reservoir
location.

Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire and
wheel assembly. The TPMS sensors monitor the
air pressure in the vehicle’s tires and transmits the tire
pressure readings to a receiver located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS turns on the low
tire pressure warning light
located on the instrument
panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message come on 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 3-44andDIC Warnings and Messages on
page 3-46.
The low tire pressure warning light may come on in
cool weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label shows the size of
your vehicle’s original equipment tires and the correct
ination pressure for your vehicle’s tires when they are
cold. SeeLoading Your Vehicle on page 4-22, for an
example of the Tire and Loading Information label and
its location on your vehicle. Also seeInflation - Tire
Pressure on page 5-52.
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 5-58andTires on page 5-46.
Notice:Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved tire
sealant available through your dealer/retailer.
5-55

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message is
also displayed. The low tire warning light and DIC warning
message come on at each ignition cycle until the problem
is corrected. Some of the conditions that can cause the
malfunction light and DIC message to come on are:
The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
Replacement tires or wheels do not match your
vehicle’s original equipment tires or wheels. Tires
and wheels other than those recommended for your
vehicle could prevent the TPMS from functioning
properly. SeeBuying New Tires on page 5-60.
Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or
signal a low tire condition. See your dealer/retailer for
service if the TPMS malfunction light and DIC message
comes on and stays on.
TPMS Sensor Matching Process
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
need to be matched to the new tire/wheel location.
The sensors are matched, to the tire/wheel locations,
in the following order: driver side front tire, passenger
side front tire, passenger side rear tire, and driver
side rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can 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. To decrease the tire’s
air-pressure use the pointed end of the valve cap,
a pencil-style air pressure gage, or a key.
