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.
If the brake system warning light comes on, there is a
brake problem. Have your brake system inspected
right away.
The brake light is located in the instrument panel
cluster.
This light should come on briey when you turn the
ignition key to RUN. If it does not come on then, have it
xed so it will be ready to warn you if there is a problem.
When the ignition is on, the brake light will come on
when you set your parking brake. The light will stay
on if your parking brake does not release fully.A chime will also sound if the parking brake is not fully
released and the vehicle is moving. If it stays on
after your parking brake is fully released, it means you
have a brake problem.
The brake light will also come on to indicate a low brake
uid level. SeeBrakes on page 5-34for more information.
If the light comes on while you are driving, 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. SeeTowing
Your Vehicle on page 4-27.
{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 StatesCanada

Antilock Brake System Warning
Light
For vehicles with
the Antilock Brake
System (ABS), this light
will come on briey
when you start the engine.
That 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.
If the ABS light stays on, turn the ignition off, if the light
comes on when you are driving, stop as soon as it is
safely possible and turn the ignition off. Then start the
engine again to reset the system. If the ABS 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 antilock brakes. If the regular brake system
warning light is also on, you do not have antilock brakes
and there is a problem with your regular brakes.
SeeBrake System Warning Light on page 3-33
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-52for all
brake related DIC messages.
Traction Control System (TCS)
Warning Light
Your vehicle has a
Traction Control
System (TCS) and
StabiliTrak
®warning light.
When the traction control is activated the light will
ash when the TCS is limiting wheel spin or when the
StabiliTrak
®system is active. You may feel or hear
the system working, but this is normal. This light may
also come on after extended heavy braking indicating
the brakes have become too hot to limit wheel spin.
This light will come on and stay on if the TCS is turned
off using the traction control on/off button, located
next to the gear shift lever.
If the TCS warning light comes on and stays on for an
extended period of time when the system is turned
on, your vehicle needs service. SeeTraction Control
System (TCS) on page 4-6andStabiliTrak
®System on
page 4-7for more information.

unnecessary accessories. Stop and turn off the vehicle
as soon as it is safe to do so. Have the electrical
system checked by your dealer/retailer immediately.
Connecting a battery charger to your vehicle while the
ignition is in any position other than LOCK/OFF may
cause this message to appear. If you need to charge
your vehicle, make sure that the key is in LOCK/OFF
or out of the ignition during charging.
SERVICE BRAKE SYSTEM
This message displays and a chime sounds when the
brake uid level is low. The brake system warning
light also appears on the instrument panel cluster when
this message appears on the DIC. SeeBrake System
Warning Light on page 3-33. Have the brake system
serviced by your dealer/retailer as soon as possible.
SERVICE POWER STEERING
On some vehicles, this message displays when a
problem is detected with the power steering system.
When this message is displayed, you may notice that
the effort required to steer the vehicle increases or feels
heavier, but you will still be able to steer the vehicle. Have
your vehicle serviced by your dealer/retailer immediately.
SERVICE STABILITRAK
This message displays if there has been a problem
detected with the StabiliTrak®System. A warning light
also appears on the instrument panel cluster. See
Traction Control System (TCS) Warning Light on
page 3-34. SeeStabiliTrak
®System on page 4-7
for more information.
If this message turns on while you are driving, pull
off the road as soon as possible and stop carefully.
Try resetting the system by turning the ignition off and
then back on. If this message still stays on or turns back
on again while you are driving, your vehicle needs
service. Have the StabiliTrak
®System inspected by
your dealer/retailer as soon as possible.

Control of a Vehicle
The following three systems help to control your vehicle
while driving — brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road can
provide. Meaning, you can lose control of your vehicle.
SeeTraction Control System (TCS) on page 4-6.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Braking
SeeBrake System Warning Light on page 3-33.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds
or more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do
alcohol, drugs, and frustration. But even in three-fourths
of a second, a vehicle moving at 60 mph (100 km/h)travels 66 feet (20 m). That could be a lot of distance in
an emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of the brakes; the weight of
the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. The brakes might not have time to cool
between hard stops. The brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal could get harder to push down. If the
engine stops, you will still have some power brake
assist. But you will use it when you brake. Once the
power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-34.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.
ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply the
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might hear
the antilock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
4-5

Braking in Emergencies
With ABS, you can steer and brake at the same time. In
many emergencies, steering can help you more than
even the very best braking.
Panic Brake Assist
Your vehicle has a Panic Brake Assist feature designed
to assist the driver in stopping or decreasing vehicle
speed in emergency driving conditions. This feature
uses the Electronic Stability Control (ESC) hydraulic
brake control module to supplement the power
brake system under conditions where the driver has
quickly and forcefully applied the brake pedal in
an attempt to quickly stop or slow down the vehicle. The
ESC hydraulic brake control module increases brake
pressure at each corner of the vehicle until the Antilock
Brake System (ABS) activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake
pedal as the driving situation dictates. The Panic Brake
Assist feature will automatically disengage when the
brake pedal is released or brake pedal pressure
is quickly decreased.
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 more of the wheels are spinning or beginning to lose
traction. When this happens, the system works the
brakes and reduces engine power to limit wheel spin.
This light ashes while the
traction control system is
limiting wheel spin.
You may feel or hear the system working, but this is
normal. This light may also come on after extended
heavy braking indicating the brakes have become too
hot to limit wheel spin.
4-6

The traction control system automatically comes on
whenever the vehicle is started. 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,
ice, or snow and rocking the vehicle is required. See
Rocking Your Vehicle to Get It Out on page 4-22.
The traction control system
can be turned off by
pressing the traction
control button, located next
to the gear shift lever.
When the traction control system is turned off, the
traction control warning light on the instrument panel
cluster comes on and TRACTION CONTROL OFF
briey displays.The traction control system can be activated again by
pressing the traction control button. While the traction
control system is activated, the traction control system
warning light on the instrument panel cluster comes
on and TRACTION CONTROL ON briey displays.
If the system is limiting wheel spin when you press the
button, the traction control off light appears on the
instrument panel cluster. The system will not turn off
until there is no longer a current need to limit wheel spin.
Turn the system back on by pressing the button
again. If the light does not come on, traction control
might not be working and your vehicle should be
serviced by a dealer/retailer.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.
StabiliTrak®System
Your vehicle has this feature. The StabiliTrak®system
is an advanced 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 and reducing engine power. The
StabiliTrak
®system comes on automatically whenever
you start your vehicle.
4-7

The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system and
StabiliTrak
®warning light on the instrument panel
cluster will be on after rst driving the vehicle and
exceeding 30 mph 48 (km/h) for 30 seconds. The
StabiliTrak
®system is off until the light has turned off.
This could take up to 15 minutes. SeeDIC Warnings
and Messages on page 3-52for more information.
The traction control system and StabiliTrak
®warning
light on the instrument panel cluster will ash when the
system is operating. You may also feel or hear the
system working. This is normal. This light may
also come on after extended heavy braking indicating
the brakes have become too hot to limit wheel spin.
StabiliTrak
®can be turned off using the traction control
button. To disable StabiliTrak®, press and hold the
traction control button for ve seconds. StabiliTrak®can
be activated again by pressing the traction control button.
The SERVICE STABILITRAK message will be displayed
and the traction control system and StabiliTrak
®warning
light on the instrument panel cluster will come on if there
is a problem with the system. When this light and the
SERVICE STABILITRAK message are on, the system is
not operational. Adjust your driving accordingly.
All-Wheel Drive (AWD) System
If your vehicle has all-wheel drive (AWD), the AWD
system operates automatically without any action
required by the driver. If the front drive wheels begin to
slip, the rear wheels will automatically begin to drive
the vehicle as required. Torque is also applied to
the rear wheels during launches. There may be a slight
engagement noise during hard use but this is normal.
This light is located on the
instrument panel cluster.
This light and the SERVICE ALL WHEEL DRIVE
message in the DIC will come on and stay on to indicate
there may be a problem with the drive system and
service is required.
SeeService All-Wheel Drive Light on page 3-42and
DIC Warnings and Messages on page 3-52for
more information.

Off-Road Recovery
You may nd that your vehicle’s right wheels have
dropped off the edge of a road onto the shoulder while
you are driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way,
steer so that your vehicle straddles the edge of
the pavement. You can turn the steering wheel up to
one-quarter turn until the right front tire contacts
the pavement edge. Then turn the steering wheel to go
straight down the roadway.
Passing
Passing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing,
we suggest the following tips:
Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass. If
in doubt, wait.
Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your side
of the lane.
Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
Wait your turn to pass a slow vehicle.
When you are being passed, ease to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
4-12

Driving in Rain and on Wet Roads
Rain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or owing water.
{CAUTION:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of
the vehicle.
After driving through a large puddle of water
or a car/vehicle wash, lightly apply the brake
pedal until the brakes work normally.
CAUTION: (Continued)
CAUTION: (Continued)
Flowing or rushing water creates strong
forces. Driving through owing water could
cause your vehicle to be carried away. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warnings
and be very cautious about trying to drive
through owing water.
Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
