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 rear wheels are spinning too much
or are beginning to lose traction. When this happens,
the system works the rear brakes and reduces
engine power by closing the throttle and managing
engine spark to limit wheel spin.
If your vehicle has TCS, there is a ESC/TCS button
located on the instrument panel.
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.
SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-29
for more information.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.
SeeTurn Signal/Multifunction Lever on page 3-7.
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 3-41for 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 4-22.
To turn the system off or
on, press and release the
ESC/TCS 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 that any of the wheels are spinning
or beginning to lose traction while driving. For more
information on the LOW TRACTION message,
seeDriver Information Center (DIC) on page 3-38.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, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the rear
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the rear 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.
Limited-Slip Rear Axle
Your vehicle may have a limited-slip rear differential
which provides maximum power and performance.
It is designed to 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.
During a sudden shift, such as shifting from FIRST (1)
to SECOND (2) gear at low engine speeds or suddenly
applying the clutch, you may feel or hear a clunking
or rattling noise. This is normal.
Electronic Stability Control (ESC)
Your vehicle may have an Electronic Stability Control
(ESC) system which combines antilock brake, and
traction and stability control systems that help the driver
maintain directional control of the vehicle in most
driving conditions.
When the vehicle is started and begins to move, 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 comes on, and the ESC OFF and/or SERVICE ESC
message displays.
For more information, seeDriver Information Center
(DIC) on page 3-38andElectronic Stability Control
(ESC)/Traction Control System (TCS) Indicator/Warning

This light ashes on the
instrument panel cluster
while the ESC system
is on and activated.
ESC activates when the computer senses a discrepancy
between your intended path and the direction the vehicle
is actually traveling. ESC selectively applies braking
pressure at any one of the vehicle’s brakes to help steer
the vehicle in the direction which you are steering.
When the system activates, an ESC ACTIVE message
displays on the Driver Information Center. SeeDIC
Warnings and Messages on page 3-41. This light ashes
on the instrument panel cluster when the ESC system
is on and activated. You may also hear a noise or
feel vibration in the brake pedal. This is normal.
Continue to steer the vehicle in the direction you want
it to go.
When the light is comes on and the message(s)
SERVICE ESC, ESC OFF, or both displays, the system
will not assist the driver in maintaining directional
control of the vehicle. Adjust your driving accordingly.
SeeDIC Warnings and Messages on page 3-41.SeeElectronic Stability Control (ESC)/Traction Control
System (TCS) Indicator/Warning Light on page 3-29
for more information.
The Electronic Stability Control (ESC) system is
automatically enabled whenever the vehicle is started.
To assist the driver with vehicle directional control,
especially in slippery road conditions, you should always
leave the system on. But, ESC can be turned off if
needed.
If the vehicle is in cruise control while the system begins
to assist the driver maintain directional control of the
vehicle, the ESC/TCS light ashes and the cruise control
automatically disengages. When road conditions allow
you to use cruise again, you may re-engage the
cruise control. SeeCruise Control on page 3-10.
The ESC/TCS button
is located on the
instrument panel.
The traction control system can be turned off or back on
by pressing the ESC/TCS button. To disable both
traction control and ESC, press and hold the button from
ve to ten seconds.

When the ESC system is turned off, the TRACTION
OFF and ESC OFF messages appear, and the
ESC/TCS light comes on to warn the driver that both
traction control and ESC are disabled.
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 4-22. Also,
see “Competitive Driving Mode” later in this section.
ESC may also turn off automatically if it determines that
a problem exists with the system. The ESC OFF and
SERVICE ESC messages and the ESC/TCS light comes
on to warn the driver that ESC is disabled and requires
service. If the problem does not clear after restarting
the vehicle, see your dealer/retailer for service.
SeeDIC Warnings and Messages on page 3-41for
more information.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3for more information.Competitive Driving Mode
The driver can select this optional handling mode by
pressing the ESC/TCS button on the console two times
within a ve second time period. COMPETITIVE
MODE displays in the DIC. SeeDIC Warnings and
Messages on page 3-41for more information.
Competitive Driving Mode allows the driver to have full
control of the rear wheels while the ESC system
helps maintain directional control of the vehicle by
selective brake application. The ESC/TCS light will be
on and the traction control system will not be operating.
Adjust your driving accordingly. This electronic stability
control mode is recommended only for use during closed
track events and competitive driving venues.
When the ESC/TCS button is pressed again, or the
vehicle is restarted, the ESC and TCS turn back on.
Notice:When traction control is turned off, or
Competitive Driving Mode is active, it is possible to
lose traction. If you attempt to shift with the rear
wheels spinning with a loss of traction, it is possible
to cause damage to the transmission. Do not
attempt to shift when the rear wheels do not have
traction. Damage caused by misuse of the vehicle is
not covered. See your warranty book for additional
information.

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 and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle has the Traction Control System
(TCS), remember: It helps to avoid only the acceleration
skid. SeeTraction Control System (TCS) on page 4-6.
If you do not have TCS, or if the 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.
If your vehicle has Electronic Stability Control (ESC),
the ESC might activate. SeeElectronic Stability Control
(ESC) on page 4-8.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 might 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.
Even though your vehicle has Electronic Stability
Control (ESC) with Antilock Brake System (ABS),
remember: ABS helps avoid only the braking skid.
If the ABS is ever disabled, in a braking skid, where
the wheels are no longer rolling, release enough
pressure on the brakes to get the wheels rolling again.
This restores steering control. Push the brake pedal
down steadily when you have to stop suddenly.
As long as the wheels are rolling, you will have
steering control.

Driving at Night
Night driving is more dangerous than day driving because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because your headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns
or curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.
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.
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.

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You might want to put winter emergency supplies
in your trunk.
Include an ice scraper, a small brush or broom, a
supply of windshield washer uid, a rag, some winter
outer clothing, a small shovel, a ashlight, a red
cloth, and a couple of reective warning triangles. And,
if you will be driving under severe conditions, include
a small bag of sand, a piece of old carpet, or a couple
of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Also seeTires on page 5-50.
Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation.
You have a lot less traction, or grip, and need to be
very careful.What is the worst time for this? Wet ice. Very cold snow
or ice can be slick and hard to drive on. But wet ice
can be even more trouble because it can offer the least
traction of all. You can get wet ice when it is about
freezing, 32°F (0°C), and freezing rain begins to fall.
Try to avoid driving on wet ice until salt and sand crews
can get there.

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.
You can run the engine to keep warm, but be careful.
