Once through water, always try the brakes.
Wet brakes will not stop your vehicle as
quickly as dry brakes. Apply light pressure
to the brake pedal while slowly moving the
vehicle to dry the brakes.
Note:
Driving through deep water could
cause damage to 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 could 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. Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, and you
could lose control of your vehicle.
When descending a steep hill, do not
descend the hill in neutral. Avoid sudden
hard braking to keep the front wheels rolling
and to maintain your vehicle's steering.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
Note: If your vehicle gets stuck driving on
hilly or sloping terrain, it may be rocked out
by shifting between forward and reverse
gears, stopping between shifts in a steady
pattern. Press lightly on the accelerator in
each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat. 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.
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 an all-wheel
drive vehicle accelerates 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 of the road conditions.

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 driving from a car wash or
standing water to dry the brakes. 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 could 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 334).
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 turns off if
there is a malfunction or if you excessively
rev the engine.
