PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system automatically turns on each
time you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information
display showing system status.
You can switch the system off by using the
switch. Using a Switch
(If Equipped)
Use the traction control switch on the
center console near the shifter to switch
the system off or on. The traction control switch.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
•
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the systems
applies higher brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one
or more of the wheels individually.

WHAT IS HILL DESCENT
CONTROL
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
Note: The system does not function below
3 mph (5 km/h)
.
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.
The system can maintain vehicle speeds
on downhill slopes between
3– 20 mph
(5– 32 km/h). Above 20 mph (32 km/h),
the system remains on but the descent
speed cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The
amount of time that the system can
remain active before cooling varies with
conditions. The system provides a warning
in the message center and a tone sounds
when the system is about to disengage for
cooling. At this time, manually apply the
brakes as needed to maintain descent
speed. SWITCHING HILL DESCENT
CONTROL ON AND OFF Press the button on the center
console. A light illuminates in the
control and a tone sounds when
the system is active.
SETTING THE HILL DESCENT
SPEED WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission. WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.
When you reach the speed you prefer,
either by accelerating or decelerating,
remove your feet from the pedals. The
system maintains the chosen vehicle
speed.

When you shift into neutral (N), the system
only provides visual indication if your
vehicle is moving at a speed of
approximately 5 mph (8 km/h) or below,
for example, your vehicle is moving on a
slope, and the system detects an object
moving toward your vehicle. When you
stop your vehicle, visual indication stops
after four seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED) WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors.
Note: Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts. Note:
If you switch traction control off, the
side sensing system also turns off.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
Note: The system does not detect an object
that is moving toward the side of your
vehicle, for example another vehicle moving
at low speed, if it does not pass a front or
rear sensor.
The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as
your vehicle moves past them.
The sensors are on the front and rear
bumpers.
The system may not function if:
• You switch the ignition on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.
To reinitialize the system, you may have to
drive your vehicle approximately 10 ft
(3 m). 234
