Brake System Warning Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
This light should come on when you start the engine. If
it does not come on then, have it ®xed so it will be
ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer to
Parking Brake on page 2-26to see if it is set. If the parking brake is not set, have
your brake system inspected right away.If the light comes on while you are driving and you have
a LOW BRAKE FLUID message showing on the DIC,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go
closer to the ¯oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service. See
Towing Your Vehicle on page 4-32.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service. United States

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
ªService ABSº under
DIC Warnings and Messages
on page 3-57.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition on. This is normal.
If the light does not come on then, have it ®xed so it will
be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
This light should come on
brie¯y as you start the
engine. If the light does not
come on then, have it
®xed so it will be ready to
warn you if there is a
problem.
The light will also come on while the Stabilitrak
žsystem
warms up and the STABILITRAK WARMING message
will be displayed in the Driver Information Center (DIC).
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYS message when you are
driving, there is a problem with your TCS and your
vehicle needs service. When this light is on, the system
will not limit wheel spin. Adjust your driving accordingly.
If the driver turns off TCS by pressing the button on
the console, the TCS system light will come on and the
TRACTION SYSTEM-OFF message will show on
the DIC.

If the light stays on or comes on while you are driving, a
chime sounds and a SERVICE STABILITRAK message
appears on the DIC, there is a problem with your
Stabilitrak
žand the vehicle needs service.
You can acknowledge this message by pressing the
RESET button. When the SERVICE STABILITRAK
message is displayed, the Stabilitrak
žsystem will not
assist you in controlling the vehicle. You should have the
system serviced as soon as possible. Adjust your
driving accordingly.
When the system is working, you will see the
STABILITRAK ACTIVE message displayed in the DIC.
You may also feel of hear the system working. This
is normal.
If you turn off the Stabilitrak
žsystem by pressing the
button on the console, the traction control system
light will come on, a chime will sound and the
TRAC/STABILITRAK OFF message will be displayed in
the DIC. The Traction Control System will also be
turned off. See
DIC Warnings and Messages on
page 3-57for more information.
If the Stabilitrak
žsystem and Traction Control System
are turned off, pressing the console button momentarily
will turn both systems on. The DIC will display the
TRAC/STABILITRAK ON message, the instrument
cluster light will be off and a chime will sound. See
DIC
Warnings and Messages on page 3-57for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
As the pointer nears 260ÉF (125ÉC), your engine coolant
temperature is high. A message may display on the
Driver Information Center (DIC) depending on how high
the temperature is. See
DIC Warnings and Messages
on page 3-57for more information.

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa). In
certain situations such as long, extended idles on
hot days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. See
DIC Warnings and
Messages on page 3-57andEngine Oil on page 5-13.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

STABILITRAK ACTIVE:You may see the
STABILITRAK ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you
are steering. This stability enhancement system
activates when the computer senses that your vehicle is
just starting to spin, as it might if you hit a patch of
ice or other slippery spot on the road. When the system
is on, you may hear a noise or feel a vibration in the
brake pedal. This is normal.
When the STABILITRAK ACTIVE message is on, you
should continue to steer in the direction you want to go.
The system is designed to help you in bad weather
or other difficult driving situations by making the most ofwhatever road conditions will permit. If the
STABILITRAK ACTIVE message comes on, you will
know that something has caused your vehicle to start to
spin, so you should consider slowing down. A single
chime will also sound when this message is displayed.

and hear a chime, the system has completed the
functional check of the Stabilitrak
žSystem.
STABILITRAK WARMING:When you ®rst start your
vehicle and drive away, especially during cold winter
weather, the STABILITRAK WARMING message may
be displayed in the DIC along with a chime and the
traction control warning light. This is normal. You can
acknowledge this message by pressing the RESET
button. The Stabilitrak
žperformance is affected until
the STABILITRAK READY message is displayed in
the DIC.
SVC TIRE MONITOR:If this message comes on, a
part on the Tire Pressure Monitor (TPM) is not working
properly. If you drive your vehicle while any of the
four sensors are missing or inoperable, the warning will
come on in approximately 10 minutes. If all four
sensors are missing, the warning will come on in
approximately 15 to 20 minutes. (All the sensors would
be missing, for example, if you put different wheels
on your vehicle without transferring the sensors.) If the
warning comes on and stays on, there may be a
problem with the TPM. See your dealer.

Anti-lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and 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 a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. See
Anti-Lock
Brake System Warning
Light on page 3-46
.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is 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.
