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.
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 thethrottle lightly while holding a light brake pressure and
ease the vehicle up and over the object.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of
your vehicle.
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.

STARTING AND OPERATING 531
Crossing Large Rocks
When approaching large rocks, choose a path which
ensures you drive over the largest 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.
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.
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.
WARNING!
There is an increased risk of rollover when crossing
an obstacle, at any angle, with steep sides.
532 STARTING AND OPERATING
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 roll over, which may result in
severe injury or death.
• Driving Down Hill – 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 (Low
Range) with the transmission in first gear (manually
select first gear on automatic transmissions) and pro-
ceed with caution. Allow engine braking to control the
descent and apply your brakes if necessary, but do not
allow the tires to lock.
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.
• 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 down hill wheels, which increases
the possibilities of a down hill 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.
5
STARTING AND OPERATING 535
WARNING!
Driving across an incline increases the risk of a
rollover, which may result in severe injury.
• 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 the
compression braking of the engine and transmission to
help regulate your speed. If the brakes are required to
control vehicle speed, apply them lightly and avoid
locking or skidding the tires.
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 RE-
VERSE. Never back down a hill in NEUTRAL using
only the vehicle brakes. Never drive diagonally across
a hill, always drive straight up or down.
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. You should only drive through areas which are
designated and approved. You should tread lightly and
avoid damage to the environment. You should know
536 STARTING AND OPERATING
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.
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.
Airing Down For Off-Road Driving
Running lower tire pressure off-road can improve your
ride comfort and vehicle traction. Reducing the tire air
pressure allows the tire to bulge slightly, improving itssurface area for better flotation and ability to mold or form
to the ground contour. Different terrain, tires, and vehicles
require different tire pressure. Hard surfaces like rock and
heavier vehicles require higher pressures than softer sur-
faces such as sand and lighter vehicles. You will need to
experiment to determine what is right for your situation. It
is easier and faster to let air out than it is to replace it so,
start high and lower it as required. Remember you must
return the tires to normal air pressure before driving on
road or at highway conditions. Be sure you have a way to
return the tires to their normal on road air pressure.
CAUTION!
Reduced tire pressure increases the risk of tire dam-
age and may cause tire unseating with total loss of air
pressure. To reduce the risk of tire unseating, while at
a reduced tire pressure, drive at slower speeds and
avoid sharp turns or abrupt maneuvers.

wood dowel. This will keep the straps from becoming
knotted and is safer than using a clevis pin if the strap
breaks. Next have the tow vehicle backup, leaving two
to three feet worth of slack in the strap. Then the tow
vehicle, using light throttle, should accelerate tighten-
ing the strap providing the pulling force needed to free
the vehicle. The vehicle being recovered should assist
in the recovery, at the time of the snap, by slowly
spinning the tires in the same direction as the pulling
vehicle. After the vehicle becomes free, the driver of
the previously stuck vehicle should signal they are free
and should hit their brakes stopping both vehicles. The
driver of the pulling vehicle should let off the throttle
without using the brakes, once signaled by the other
driver. This sequence is important to avoid having the
recovered vehicle hit the pulling vehicle.WARNING!
Never use tow straps with end hooks or link two
straps with a clevis pin. These heavy metal objects
could become projectiles if a strap breaks, which
could cause severe injury. Never leave more than two
or three feet of slack in the strap. More slack than this
greatly increases the risk of injury and vehicle dam-
age. Always keep everyone at least 30 feet away from
a strapping or winching situation.
• Winching (Refer To “Winch Operation” For Addi-
tional Information) – Winching is most commonly
used in the following situations: there is no support
vehicle available, a high controlled force is required to
recover the vehicle, there is a high risk of environmen-
tal or vehicle damage, or where nothing else seems to
work. A winch can deliver a high pulling force with a
great deal of control. It allows you to walk the vehicle
542 STARTING AND OPERATING
out of the situation in a slow controlled manner. This
control works well for avoiding further vehicle dam-
age. Once you decide it is time to use the winch look
for a good anchor point. It needs to be strong enough
to hold more than the vehicle’s weight and provide a
direction of pull as straight as possible. Use block and
tackle if necessary to improve the angle of pull or
increase the winch’s pulling force. If the anchor point
is a tree use a strap around its base and hook the cable
to the strap. If it is another vehicle, then place that
vehicle in PARK and block the front tires. If you cannot
find an anchor point within reach try using your spare
tire by burying it. Once you have determined an
anchor point hook up the cable, ensuring there are a
least five wraps of cable left on the drum, and place a
floor mat or something else over the strung out cable.
Placing something over the strung out cable helps
keep the cable on the ground if it breaks. Next, place
the vehicle in first gear and apply a very light throttleas you power the winch in. Be careful not to allow
slack in the cable as you recover the vehicle. Do not try
to guide the cable into the drum. If it starts to bunch up
on one end, let it. You can re-spool the cable after-
wards. Never use a winch cable as a tow strap and
always stand back while winching.
WARNING!
Winch cables are under high tension when in use and
can become a projectile if they fail. Never stand over
or straddle the winch cable. Never jerk or overload
the winch cable. Never stand in front of the vehicle
while winching. Failure to follow these instructions
can result in serious or fatal injury.

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 sus-
pension. 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.
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.
