pedal when changes in vehicle speed are
required. Avoid abrupt steering, acceleration
and braking. This could result in an increased
risk of vehicle roll over, loss of vehicle control
and personal injury. Use all available road
surface to bring your vehicle to a safe
direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of surface
to another (i.e. from concrete to gravel) there
can be a change in the way your vehicle
responds to a maneuver, i.e. steering,
acceleration or braking.
DRIVING IN SAND
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation can
maximize the engine and transmission
cooling capability.
Avoid driving at excessive speed. This
causes vehicle momentum to work against
you and your vehicle could become stuck to
the point that assistance may be required
from another vehicle. Remember, you may
be able to back out the way you came if you
proceed with caution.
DRIVING THROUGH MUD AND WATER
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander. Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can lose
traction in slick mud. If your vehicle does
slide, steer in the direction of the slide until
you regain control of your vehicle. After
driving through mud, clean off residue stuck
to rotating driveshafts and tires. Excess mud
stuck on tires and rotating driveshafts can
cause an imbalance that could damage drive
components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited. When driving through water,
determine the depth and avoid water higher
than the bottom of the hubs. If the ignition
system gets wet, your vehicle may stall. Once
through water, test the brakes. Wet brakes
do not stop your vehicle as effectively as dry
brakes. Drying improves by applying light
pressure to the brake pedal while moving
slowly.

(If Equipped)

Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
DRIVING ON HILLY OR SLOPING
TERRAIN
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should try to drive
straight up or straight down.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you can use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer. When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turnaround
because this could cause vehicle roll over.
It is better to reverse back to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power can cause
the tires to slip, spin or lose traction, resulting
in loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your vehicle.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes. DRIVING ON SNOW AND ICE
Four-wheel drive vehicles have advantages
over two-wheel drive 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. Although a four-wheel drive vehicle
can accelerate better than a two-wheel drive
vehicle in snow and ice, it cannot stop any
faster as 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.
Do not pump the brake pedal. See Anti-Lock
Braking System Limitations (page 233).

BRAKE PRECAUTIONS
WARNING: Driving your vehicle with
the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or driving
from standing water to dry the brakes.
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop. ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and travel further.
Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 415).
CHECKING THE BRAKE FLUID WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to pull
away when your vehicle is on a slope without
using the parking brake.
HOW DOES HILL START ASSIST
WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake pedal
to the accelerator pedal. The brakes release
when the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope.
HILL START ASSIST PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system will turn off
if a malfunction is apparent. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. HILL START ASSIST –

WHAT IS TRACTION CONTROL
The traction control system helps to avoid
drive wheel spin and loss of traction.
HOW DOES TRACTION CONTROL
WORK
If your wheels begin to spin, the loss of
traction can compromise steering control
and stability of the vehicle. The traction
control system applies the brakes to
individual wheels and when needed, reduces
engine power at the same time to increase
traction.
SWITCHING TRACTION CONTROL
ON AND OFF WARNING: 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 traction control system turns on each
time you switch the ignition on.
The button for the stability and traction
control system is on the instrument panel.
Press and release the button to switch
traction control off. The stability control
system remains fully active, to switch it off,
press and hold the button for a few seconds,
then release.
When you switch traction control off, a
message and an illuminated icon appear on
the instrument cluster.Press the switch again to turn the traction
control system back on to normal operation.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Your vehicle may have MyKey restrictions
regarding this feature.
See What Is MyKey
(page 82).
TRACTION CONTROL INDICATOR
Stability and Traction Control Indicator If the indicator does not illuminate
when you switch the ignition on,
or remains on when the engine is
running, this indicates a malfunction. Have
your vehicle checked by an authorized
dealer as soon as possible. The traction control off indicator
illuminates when you switch the
traction control system off, or when
an alternative stability control mode is
selected that requires the traction control off
depending on the drive mode selected.
