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.

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.

Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of the tires and the road surface, the angle at
which the curve is banked, and your speed. While
you are in a curve, speed is the one factor you
can control.
Suppose you are steering through a sharp curve. Then
you suddenly accelerate. Both control systems —
steering and acceleration — have to do their work where
the tires meet the road. Adding the sudden acceleration
can demand too much of those places. You can lose
control. SeeTraction Control System (TCS) on page 4-6
andStabiliTrak
®System on page 4-7.What should you do if this ever happens? Ease up on
the brake or accelerator pedal, steer the vehicle the way
you want it to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course, the posted speeds
are based on good weather and road conditions.
Under less favorable conditions you will want to
go slower.
If you need to reduce your speed as you approach a
curve, do it before you enter the curve, while the
front wheels are straight ahead.
Try to adjust your speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
4-10

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 overdriving
those conditions. But skids are always possible.
The three types of skids correspond to your vehicle’s
three control systems. In the braking skid, the 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 traction system is off,
then an acceleration skid is also best handled by easing
your foot off the accelerator pedal. SeeTraction
Control System (TCS) on page 4-6andStabiliTrak
®
System on page 4-7.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 reducing vehicle speed 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 — such as enough water, ice, or packed snow on
the road to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Antilock Brake System (ABS) helps
avoid only the braking skid.
4-13

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.
4-15

Whatever the condition — smooth ice, packed, blowing,
or loose snow — drive with caution.
Traction control improves your ability to accelerate when
driving on a slippery road. But you can turn the
traction system off if you ever need to. You should turn
the traction system off if your vehicle ever gets stuck
in sand, mud, ice, or snow. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 4-21. Even
though your vehicle has a traction system, slow down
and adjust your driving to the road conditions. Under
certain conditions, you might want to turn the traction
system off, such as when driving through deep
snow and loose gravel, to help maintain vehicle motion
at lower speeds. SeeTraction Control System (TCS)
on page 4-6andStabiliTrak
®System on page 4-7.
The Antilock Brake System (ABS) improves your
vehicle’s stability when you make a hard stop on a
slippery road. Even though you have ABS, begin
stopping sooner than you would on dry pavement.
SeeAntilock Brake System (ABS) on page 4-5.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be ne
until you hit a spot that is covered with ice. On
an otherwise clear road, ice patches can appear in
shaded areas where the sun cannot reach, such
as around clumps of trees, behind buildings,
or under bridges. Sometimes the surface of a curveor an overpass can remain icy when the surrounding
roads are clear. If you see a patch of ice ahead
of you, brake before you are on it. Try not to brake
while you are actually on the ice, and avoid
sudden steering maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with
your vehicle unless you know for sure that you are near
help and you can hike through the snow. Here are
some things to do to summon help and keep yourself
and your passengers safe:
Turn on the hazard warning ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you do not have blankets or extra clothing, make
body insulators from newspapers, burlap bags,
rags, oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.

Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right to clear
the area around the front wheels. Turn off any
traction or stability system. SeeTraction Control
System (TCS) on page 4-6andStabiliTrak
®System on
page 4-7. Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. To prevent transmission wear,
wait until the wheels stop spinning before shifting gears.
Release the accelerator pedal while you shift, and
press lightly on the accelerator pedal when the
transmission is in gear. By slowly spinning the wheels in
the forward and reverse directions, you will cause a
rocking motion that could free your vehicle. If that does
not get your vehicle out after a few tries, it might
need to be towed out. If your vehicle does need to be
towed out, seeTowing Your Vehicle on page 4-27.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. Two labels on your vehicle
show how much weight it may properly carry, the
Tire and Loading Information label and the
Vehicle Certication label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.
