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.
STABILITRAK READY:If you receive this message
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.
4-7
Traction Control System (TCS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system works the rear brakes and reduces engine
power to limit wheel spin.
The TRAC SYSTEM ACTIVE message will display on
the Driver Information Center (DIC) when the traction
control system is limiting wheel spin. See
DIC Warnings
and Messages on page 3-57. You may feel or hear
the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. See ªCruise Controlº under
Turn Signal/Multifunction Lever on page 3-5.This warning light will
come on to let you know if
there is a problem with
your traction control
system.
See
Traction Control System (TCS) Warning Light on
page 3-46. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes
on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See ªRocking Your Vehicle To Get It Outº
under
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-31.
4-9
To turn the system off,
press the traction control
button located on the
center console.
The TRACTION SYSTEM-OFF message will display on
the DIC and the traction control system warning light
will come on. If the system is limiting wheel spin when
you press the button, the TRACTION SYSTEM-OFF
message will display ± but the system will not turn
off right away. It will wait until there is no longer
a current need to limit wheel spin.
You can turn the system back on at any time by
pressing the button again. The TRACTION SYSTEM-ON
message should display brie¯y on the Driver Information
Center.Magnetic Ride Control
Magnetic Ride Control automatically adjusts the ride of
your vehicle. Automatic ride control is achieved
through a computer used to control and monitor the
suspension system. The controller receives input from
various sensors to determine the proper system
response. If the controller detects a problem within the
system, the DIC will display a SERVICE RIDE
CONTROL message. See
DIC Warnings and Messages
on page 3-57for more information. See your dealer
for service.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when one of
the rear wheels has no traction and the other does, this
feature will allow the wheel with traction to move the
vehicle.
4-10
StabilitrakžSystem
The StabilitrakžSystem is a computer controlled system
that helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle's brakes.
When you ®rst start your vehicle and begin to drive
away (6 mph (10 km/h)), especially during cold weather,
the message STABILITRAK WARMING may be
displayed in the Driver Information Center (DIC), the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The
Stabilitrak
žSystem performance is affected until the
message, STABILITRAK READY, is displayed in
the DIC.
The WAIT FOR STABILITRAK message may be
displayed in the DIC after exceeding 19 mph (30 km/h)
for 10 seconds if the steering is not centered. The
system is off until the STABILITRAK ACTIVE message
is displayed.
The STABILITRAK ACTIVE message will come on
when the system is operating. See
DIC Warnings and
Messages on page 3-57for more information. You
may also feel or hear the system working. This
is normal.The instrument cluster light
will come on and a chime
will sound to let you
know if there is a problem
with the system.
The SERVICE STABILITRAK message will also be
displayed. See
DIC Warnings and Messages on
page 3-57for more information.
When this light and the SERVICE STABILITRAK
message are on, the system is not operational. Adjust
your driving accordingly.
The system comes on automatically whenever you start
your vehicle. To help maintain directional control of
the vehicle, you should always leave the system on. You
can turn the system off if you ever need to. If you turn
the STABILITRAK
žSystem off, the Traction Control
System will also be turned off. Adjust your driving
accordingly.
4-11
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
ªoverdrivingº those conditions. But skids are always
possible.
The three types of skids correspond to your vehicle's
three control systems. In the braking skid, your wheels
are not rolling. In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip
and lose cornering force. And in the acceleration
skid, too much throttle causes the driving wheels
to spin.
A cornering skid is best handled by easing your foot off
the accelerator pedal.
Remember: Any traction control system helps avoid only
the acceleration skid. If your TCS system is off, then
an acceleration skid is also best handled by easing your
foot off the accelerator pedal.If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want
the vehicle to go. If you start steering quickly enough,
your vehicle may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel or other material is on the road. For safety,
you will want to slow down and adjust your driving to
these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration
or braking (including engine braking by shifting to a
lower gear). Any sudden changes could cause the tires
to slide. You may not realize the surface is slippery
until your vehicle is skidding. Learn to recognize warning
clues Ð such as enough water, ice or packed snow
on the road to make a ªmirrored surfaceº Ð and slow
down when you have any doubt.
Remember: Any anti-lock brake system (ABS) helps
avoid only the braking skid.

Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come in
through your engine's air intake and badly damage
your engine. Never drive through water that is
slightly lower than the underbody of your vehicle. If
you can not avoid deep puddles or standing
water, drive through them very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through ¯owing
water, as you might at a low water crossing,
your vehicle can be carried away. As little as
six inches of ¯owing water can carry away a

CAUTION: (Continued)
smaller vehicle. If this happens, you and
other vehicle occupants could drown. Do not
ignore police warning signs, and otherwise be
very cautious about trying to drive through
¯owing water.
Some Other Rainy Weather Tips
·Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared to have your
view restricted by road spray.
·Have good tires with proper tread depth. SeeTires
