Hill Climbing
Hill climbing requires good judgment and a good
understanding of your abilities and your vehicle's
limitations. Hills can cause serious problems.
Some are just too steep to climb and should not be
attempted. You should always feel confident with
the vehicle and your abilities. You should always
climb hills straight up and down. Never attempt to
climb a hill on an angle.
BEFORE CLIMBING A STEEP HILL
As you approach a hill, consider its grade or
steepness. Determine if it is too steep. Look to see
what the traction is on the hill side trail. Is the trail
straight up and down? What is on top and the other
side? Are there ruts, rocks, branches or other
obstacles on the path? Can you safely recover the
vehicle if something goes wrong? If everything
looks good and you feel confident, shift the
transmission into a lower gear with 4L engaged,
and proceed with caution, maintaining your
momentum as you climb the hill.
DRIVING UP HILL
Once you have determined your ability to proceed
and have shifted into the appropriate gear, line
your vehicle up for the straightest possible run.
Accelerate with an easy constant throttle and apply
more power as you start up the hill. Do not race
forward into a steep grade; the abrupt change of grade could cause you to lose control. If the front
end begins to bounce, ease off the throttle slightly
to bring all four tires back on the ground. As you
approach the crest of the hill, ease off the throttle
and slowly proceed over the top. If the wheels start
to slip as you approach the crest of a hill, ease off
the accelerator and maintain headway by turning
the steering wheel no more than a quarter turn
quickly back and forth. This will provide a fresh
"bite" into the surface and will usually provide
enough traction to complete the climb. If you do
not make it to the top, place the vehicle in
REVERSE and back straight down the grade using
engine resistance along with the vehicle brakes.
DRIVING DOWNHILL
Before driving down a steep hill, you need to
determine if it is too steep for a safe descent. What
is the surface traction? Is the grade too steep to
maintain a slow, controlled descent? Are there
obstacles? Is it a straight descent? Is there plenty
of distance at the base of the hill to regain control
if the vehicle descends too fast? If you feel
confident in your ability to proceed, then make sure you are in 4L and proceed with caution. Allow
engine braking to control the descent and apply
your brakes, if necessary, but do not allow the tires
to lock.
DRIVING ACROSS AN INCLINE
If at all possible, avoid driving across an incline. If
it is necessary, know your vehicle's abilities. Driving
across an incline places more weight on the
downhill wheels, which increases the possibilities
of a downhill slide or rollover. Make sure the
surface has good traction with firm and stable
soils. If possible, transverse the incline at an angle
heading slightly up or down.WARNING!
Never attempt to climb a hill at an angle or turn
around on a steep grade. Driving across an
incline increases the risk of a rollover, which may
result in severe injury.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine
braking. Descending a grade too fast could
cause you to lose control and be seriously
injured or killed.
WARNING!
Driving across an incline increases the risk of a
rollover, which may result in severe injury.

CROSSING DITCHES, STREAMS, SHALLOW
RIVERS OR OTHER FLOWING WATER
Flowing water can be extremely dangerous. Never
attempt to cross a fast running stream or river
even in shallow water. Fast moving water can
easily push your vehicle downstream, sweeping it
out of control. Even in very shallow water, a high
current can still wash the dirt out from around your
tires putting you and your vehicle in jeopardy.
There is still a high risk of personal injury and
vehicle damage with slower water currents in
depths greater than the vehicle's running ground
clearance. You should never attempt to cross
flowing water which is deeper than the vehicle's
running ground clearance. Even the slowest
current can push the heaviest vehicle downstream
and out of control if the water is deep enough to
push on the large surface area of the vehicle's
body. Before you proceed, determine the speed of
the current, the water's depth, approach angle,
bottom condition and if there are any obstacles.
Then cross at an angle heading slightly upstream
using the low and slow technique.
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After going
off-road, it is always a good idea to check for
damage. That way you can get any problems taken
care of right away and have your vehicle ready
when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, driveline, and exhaust system for
damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness, partic -
ularly on the chassis, drivetrain components,
steering, and suspension. Retighten them, if
required, and torque to the values specified in
the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They might
hide damage to fuel lines, brake hoses, axle
pinion seals, and propeller shafts.
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan,
brake rotors, wheels, brake linings, and axle
yokes inspected and cleaned as soon as
possible.
NOTE:Inspect the clutch vent holes in the manual trans -
mission bell housing for mud and debris and clean
as required.
If you experience unusual vibration after driving
in mud, slush or similar conditions, check the
wheels for impacted material. Impacted mate -
rial can cause a wheel imbalance and freeing
the wheels of it will correct the situation.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the
radiator.
WARNING!
Never drive through fast moving deep water. It
can push your vehicle downstream, sweeping it
out of control. This could put you and your
passengers at risk of injury or drowning.
WARNING!
Abrasive material in any part of the brakes may
cause excessive wear or unpredictable braking.
You might not have full braking power when you
need it to prevent a collision. If you have been
operating your vehicle in dirty conditions, get
your brakes checked and cleaned as necessary.

power to lessen the chance that wheel lift will
occur. ERM can only reduce the chance of wheel
lift occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due to
other factors, such as road conditions, leaving the
roadway, striking objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). See Ú page 281 for a
complete explanation of the available ESC modes.
Electronic Stability Control (ESC)
The ESC system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the brake of the appropriate wheel(s) to counteract the
above conditions. Engine power may also be
reduced to help the vehicle maintain the desired
path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the oversteer or understeer
condition.
The ESC Activation/Malfunction Indicator Light
located in the instrument cluster will start to flash
as soon as the ESC system becomes active. The
ESC Activation/Malfunction Indicator Light also
flashes when the Traction Control System (TCS) is
active. If the ESC Activation/Malfunction Indicator
Light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving
to the prevailing road conditions.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence the
chance that wheel lift or rollover may occur. ERM
cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.
WARNING!

Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from acting
on the vehicle, nor can it increase the traction
afforded by prevailing road conditions. ESC
cannot prevent accidents, including those
resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC
also cannot prevent accidents resulting from
loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent acci -
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or
dangerous manner which could jeopardize the
user’s safety or the safety of others.

Vehicle modifications, or failure to properly
maintain your vehicle, may change the handling
characteristics of your vehicle, and may nega -
tively affect the performance of the ESC system.
Changes to the steering system, suspension,
braking system, tire type and size or wheel size
may adversely affect ESC performance. Improp -
erly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modifi-
cation or poor vehicle maintenance that
reduces the effectiveness of the ESC system
can increase the risk of loss of vehicle control,
vehicle rollover, personal injury and death.

Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others. If
you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you in
a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air Bag
System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters

Occupant Classification System
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the ignition switch is in the OFF position
or in the ACC position, the air bag system is not on
and the air bags will not inflate.
The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
first in the ON/RUN position. After the self-check,
the Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.
WARNING!
Do not place the seat belt webbing behind the
rear seat stow clip when using the seat belt to
restrain an occupant. The seat belt will not be
positioned properly on the occupant and they
could be more seriously injured in an accident
as a result.
