STARTING AND OPERATING209
additional low speed pulling power is needed.
Vehicle speeds in excess of 25 mph (40 km/h)
should be avoided when in 4L range.
Simultaneous Brake And Throttle
Operation
Many off-road driving conditions require the
simultaneous use of the brake and throttle
(two-footed driving). When climbing rocks, logs, or
other stepped objects, using light brake pressure
with light throttle will keep the vehicle from jerking
or lurching. This technique is also used when you
need to stop and restart a vehicle on a steep
incline.
Driving In Snow, Mud And Sand
SNOW
In heavy snow or for additional control and traction
at slower speeds, shift the transmission into a low
gear and the transfer case into 4L if necessary. Do
not shift to a lower gear than necessary to maintain
headway. Over-revving the engine can spin the
wheels and traction will be lost. If you start to slow
to a stop, try turning your steering wheel no more than a quarter turn quickly back and forth, while
still applying throttle. This will allow the tires to get
fresh traction and help maintain your momentum.
MUD
Deep mud creates a great deal of suction around
the tires and is very difficult to get through. You
should use DRIVE, with the transfer case in the 4L
position to maintain your momentum. If you start to
slow to a stop, try turning your steering wheel no
more than a quarter turn quickly back and forth for
additional traction. Mud holes pose an increased
threat of vehicle damage and getting stuck. They
are normally full of debris from previous vehicles
getting stuck. As a good practice before entering
any mud hole, get out and determine how deep it
is, if there are any hidden obstacles and if the
vehicle can be safely recovered if stuck.
SAND
Soft sand is very difficult to travel through with full
tire pressure. When crossing soft, sandy spots in a
trail, maintain your vehicle's momentum and do
not stop. The key to driving in soft sand is using the
appropriate tire pressure, accelerating slowly, avoiding abrupt maneuvers and maintaining the
vehicle's momentum. If you are going to be driving
on large soft sandy areas or dunes, reduce your
tire pressure to a minimum of 15 psi (103 kPa) to
allow for a greater tire surface area. Reduced tire
pressure will drastically improve your traction and
handling while driving on the soft sand, but you
must return the tires to normal air pressure before
driving on pavement or other hard surfaces. Be
sure you have a way to reinflate the tires prior to
reducing the pressure.
Crossing Obstacles (Rocks And Other High
Points)
While driving off-road, you will encounter many
types of terrain. These varying types of terrain bring
different types of obstacles. Before proceeding,
review the path ahead to determine the correct
approach and your ability to safely recover the
vehicle if something goes wrong. Keeping a firm
grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward
CAUTION!
Do not use 4L range when operating the vehicle
on dry pavement. Driveline hardware damage
can result.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPM or vehicle speeds, because engine
braking may cause skidding and loss of control.
CAUTION!
Reduced tire pressures may cause tire
unseating and total loss of air pressure. To
reduce the risk of tire unseating, while at a
reduced tire pressure, reduce your speed and
avoid sharp turns or abrupt maneuvers.

210STARTING AND OPERATING
until it makes contact with the object. Apply the
throttle lightly while holding a light brake pressure
and ease the vehicle up and over the object.
USING A SPOTTER
There are many times where it is hard to see the
obstacle or determine the correct path.
Determining the correct path can be extremely
difficult when you are confronting many obstacles.
In these cases have someone guide you over,
through, or around the obstacle. Have the person
stand a safe distance in front of you where they
can see the obstacle, watch your tires and
undercarriage, and guide you through.
CROSSING LARGE ROCKS
When approaching large rocks, choose a path
which ensures you drive over the largest of them
with your tires. This will lift your undercarriage over
the obstacle. The tread of the tire is tougher and
thicker than the side wall and is designed to take
the abuse. Always look ahead and make every
effort to cross the large rocks with your tires.
CROSSING A RAVINE, GULLY, DITCH,
WASHOUT OR RUT
When crossing a ravine, gully, ditch, washout or a
large rut, the angled approach is the key to
maintaining your vehicle's mobility. Approach
these obstacles at a 45-degree angle and let each
tire go through the obstacle independently. You
need to use caution when crossing large obstacles
with steep sides. Do not attempt to cross any large
obstacle with steep sides at an angle great enough
to put the vehicle at risk of a rollover. If you get
caught in a rut, dig a small trench to the right or left
at a 45-degree angle ahead of the front tires. Use
the removed dirt to fill the rut ahead of the turnout
you just created. You should now be able to drive
out following the trench you just created at a
45-degree angle.
CROSSING LOGS
To cross a log, approach it at a slight angle
(approximately 10 to 15 degrees). This allows one
front tire to be on top of the log while the other just
starts to climb the log. While climbing the log,
modulate your brake and accelerator to avoid
spinning the log out from under your tires. Then
ease the vehicle off the log using your brakes.
GETTING HIGH-CENTERED
If you get hung up or high-centered on an object,
get out of the vehicle and try to determine what the
vehicle is hung up on, where it is contacting the
underbody and what is the best direction to
recover the vehicle. Depending on what you are in
contact with, jack the vehicle up and place a few
rocks under the tires so the weight is off of the high
point when you let the vehicle down. You can also
try rocking the vehicle or winching the vehicle off
the object.
WARNING!
Crossing obstacles can cause abrupt steering
system loading which could cause you to lose
control of your vehicle.
CAUTION!
Never attempt to straddle a rock that is large
enough to strike your axles or undercarriage.
Never attempt to drive over a rock which is
large enough to contact the door sills.
WARNING!
There is an increased risk of rollover when
crossing an obstacle, at any angle, with steep
sides.
CAUTION!
Do not attempt to cross a log with a greater
diameter than the running ground clearance or
the vehicle will become high-centered.
CAUTION!
Winching or rocking the vehicle off hard objects
increases the risk of underbody damage.

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.

STARTING AND OPERATING213
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.
