The Basics Of Off-Road Driving
You will encounter many types of terrain driving off-road.
You should be familiar with the terrain and area before
proceeding. There are many types of surface conditions:
hard-packed dirt, gravel, rocks, grass, sand, mud, snow
and ice. Every surface has a different effect on your
vehicle's steering, handling and traction. Controlling your
vehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and
maintain a good driving posture. Avoid sudden
accelerations, turns or braking. In most cases, there are
no road signs, posted speed limits or signal lights.
Therefore, you will need to use your own good judgment on
what is safe and what is not. When on a trail, you should
always be looking ahead for surface obstacles and
changes in terrain. The key is to plan your future driving
route while remembering what you are currently driving
over.
NOTE:It is recommended that the Stop/Start system and the
Forward Collision Warning (FCW) system (if equipped) be
disabled during off-road use.
When To Use 4L Range
When off-road driving, shift into 4L for additional traction
and control on slippery or difficult terrain, ascending or
descending steep hills, and to increase low speed pulling
power. This range should be limited to extreme situations
such as deep snow, mud, steep inclines, or sand where
additional low speed pulling power is needed. Vehicle
speeds in excess of 25 mph (40 km/h) should be avoided
when in 4L.
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 1/4 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 1/4 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.
WARNING!
 Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an
off-road situation.
A malfunctioning catalytic converter can reach higher
temperatures than in normal operating conditions.
This can cause a fire if you drive slowly or park over
flammable substances such as dry plants, wood,
cardboard, etc. This could result in death or serious
injury to the driver, occupants or others.
CAUTION!
Do not use 4L when operating the vehicle on dry
pavement. Driveline hardware damage can result.
WARNING!
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.

180STARTING AND OPERATING
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 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.
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.
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.

STARTING AND OPERATING181
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.
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 1/4 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 to 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.
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.
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.

182STARTING AND OPERATING
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.
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing engine
braking to control the descent and apply your brakes, if
necessary, but do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. Only drive through areas which are designated
and approved. Tread lightly and avoid damage to the
environment. Know your vehicle's abilities and be able to
recover it if something goes wrong. Never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. Shift into
FIRST gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L position
and proceed very slowly with a constant slow speed of {3
to 5 mph (5 to 8 km/h) maximum} and light throttle. Keep
the vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, inspect all of the vehicle fluids for
signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick. You
need to be sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy waters;
check for hidden obstacles. Make sure you will not be
intruding on any wildlife, and you can recover the vehicle
if necessary. The key to a safe crossing is the water depth,
current and bottom conditions. On soft bottoms, the
vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
WARNING!
Driving across an incline increases the risk of a rollover,
which may result in severe injury.
WARNING!
If the engine stalls or you lose headway or cannot make
it to the top of a steep hill or grade, never attempt to
turn around. To do so may result in tipping and rolling
the vehicle, which may result in severe injury. Always
back carefully straight down a hill in REVERSE. Never
back down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill, always drive
straight up or down.
CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can
cause permanent damage to engine, driveline or
other vehicle components, and your brakes will be
less effective once wet and/or muddy.
 When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering
as a precaution, and check all fluids afterward.
Driving through water may cause damage that may
not be covered by the New Vehicle Limited Warranty.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the radiator.

23_JL_OM_EN_USC_t.book Page 182

STARTING AND OPERATING183
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, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required.
 Check threaded fasteners for looseness, particularly
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 transmission
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 material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
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.
