Your vehicle has anti-lock brakes, therefore
apply the brakes steadily. Do not
“pump”
the brakes.
Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire
chains or cables, then it is critical that
you drive cautiously. Keep speeds down,
allow for longer stopping distances and
avoid aggressive steering to reduce the
chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
Note: Excessive tire slippage can cause
driveline damage.
4WD vehicles have advantages over 2WD
vehicles in snow and ice but can skid like
any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking as well. Although a
4WD vehicle could accelerate better than
a two-wheel drive vehicle in snow and ice,
it will not stop any faster, because as in
other vehicles, braking occurs at all four
wheels. Do not become overconfident as
to road conditions. Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Since your vehicle comes
with a four wheel (ABS), do not
“pump”
the brakes. See Hints on Driving With
Anti-Lock Brakes (page 215).
Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty and durable load
carrying capability. For this reason, we
strongly recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
Any modifications to a vehicle that raise
the center of gravity can make it more likely
the vehicle will rollover as a result of a loss
of control. We strongly recommend that
caution be used with any vehicle equipped
with a high load or device (such as ladder
or luggage racks).
Failure to maintain your vehicle properly
could void the warranty, increase your
repair cost, reduce vehicle performance
and operational capabilities and adversely
affect driver and passenger safety.
Frequent inspection of vehicle chassis
components is recommended if the vehicle
is subjected to off-highway usage.

(If Equipped)

Note:
The system does not operate during
hard acceleration or steering.
Note: If your vehicle sustains damage to
the bumper or fascia leaving it misaligned
or bent, it could alter the sensing zone
causing inaccurate measurement of
obstacles or false alerts.
Note: Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the
system may detect the trailer and provide
an alert, or the system turns off. If the
system does not turn off, switch the system
off manually after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.
SWITCHING REVERSE
BRAKING ASSIST ON AND OFF
You can switch the system on or off
through the touchscreen. See Settings
(page 464). Note:
The system is unavailable when rear
parking aid or cross traffic alert is off.
OVERRIDING REVERSE
BRAKING ASSIST
There could be instances when
unexpected or unwanted braking occurs.
Firmly pressing the accelerator pedal or
switching the feature off overrides the
system.
REVERSE BRAKING ASSIST
INDICATORS
If the system determines that a collision
with an obstacle may occur, full braking
may apply. Bring your vehicle to a stop a
safe distance away from the obstacle. A message and warning
indicator appear when the
system applies the brakes.

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.
