HOW DOES TRACTION CONTROL
WORK
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces power at the same
time. If the wheels spin when accelerating
on slippery or loose surfaces, the system
reduces power in order to increase traction.
SWITCHING TRACTION CONTROL
ON AND OFF
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.
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off with the
traction control switch.
Using a Switch
Use the traction control switch on the
instrument panel to switch the system off or
on.

HOW DOES STABILITY CONTROL
WORK
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.
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.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control 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
Roll stability control 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.

WHAT IS THE LANE KEEPING
SYSTEM
The lane keeping system alerts you by
providing temporary steering assistance or
steering wheel vibration when it detects an
unintended lane departure.
HOW DOES THE LANE KEEPING
SYSTEM WORK
L
ane-K eeping S ystem
The lane keeping system uses a forward
looking camera mounted on the windshield
to monitor vehicle movement within the
travel lane.
When the camera detects a drift out of the
travel lane, the lane keeping system alerts
the driver by vibrating the steering wheel, or
aids the driver by providing a small steering
input to move the vehicle back into the travel
lane.
The driver can select one of three modes: •
Alert (If Equipped)
• Aid
• Alert + Aid
