Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel bolts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

position to REAR LOCK while traveling less than 3 mph
(5 km/h). The RR indicator light will remain on when the
rear axle is locked.
NOTE:Left to right wheel speed difference may be neces-
sary to allow the axle to fully lock. If the indicator light is
flashing after placing the switch in the REAR LOCK or
FRONT/REAR LOCK position, drive the vehicle in a turn
or on loose gravel to expedite the locking action.
WARNING!
Do not use the locked axle position for normal driving.
A locked front axle is intended for off-road driving
only. Locking the front axle during on-road driving
will reduce the steering ability. This could cause a
collision and you may be seriously injured.
To lock the front axle; move the axle locker switch to
FRONT/REAR LOCK while traveling less than 3 mph
(5 km/h). The indicator light will be solid when the front
axle is locked.
NOTE: The rear axle must be locked before the front axle
will lock. To unlock the front axle; move the axle locker switch to
REAR LOCK. The FRONT/REAR LOCK indicator light
will go out when the axle is unlocked.
NOTE:
The axle lockers could be torque locked due to side
to side loads on the axle. Driving slowly while turning the
steering wheel from a left hand turn to a right hand turn or
driving in REVERSE for a short distance may be required
to release the torque lock and unlock the axles.
To unlock the rear axle; move the axle locker switch to
AXLE UNLOCK. The REAR LOCK indicator light will go
out when the rear axle is unlocked.
STABILIZER/SWAY BAR SYSTEM — POWER
WAGON ONLY
Your vehicle is equipped with an electronic disconnecting
stabilizer/sway bar. This system allows greater front sus-
pension travel in off-road situations.
Due to the use of taller springs, this vehicle has an
increased ride height of approximately 1.9 in (48.3 mm) in
the front and 1.5 in (38.1 mm) in the rear. A major
advantage to increasing ride height is the positive effect it
has on approach/departure and break over angles.
5
STARTING AND OPERATING 455
NOTE:The stabilizer/sway bar may be torque locked due
to left and right suspension height differences. This condi-
tion is due to driving surface differences or vehicle loading.
In order for the stabilizer/sway bar to disconnect/
reconnect, the right and left halves of the bar must be
aligned. This alignment may require that the vehicle be
driven onto level ground or rocked from side to side.
To return to the On-Road mode; push the left hand On
Road stabilizer/sway bar button.
WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is reduced. Do not attempt to
drive the vehicle over 18 mph (29 km/h). Driving faster
than 18 mph (29 km/h) may cause loss of control of the
vehicle, which could result in serious injury or death.
Contact your local service center for assistance.
SAFE OFF-ROAD DRIVING — POWER WAGON
ONLY
Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore those
wilderness trails where few travel, providing a source of
exciting and satisfying recreation. Before you venture out,
you should contact your local governmental agency to
determine the designated off-road vehicle (ORV) trails or
recreation areas. You should always tread lightly and only
use established roads, trails or ORV recreational areas.
The National Forest Service, Bureau of Land Management,
or local Department of Natural Resources are a wealth of
information and usually have maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components of
the truck including the fuel tank, transfer case and steering
damper. In addition, this vehicle is equipped with boxed
cross members and fore/aft rails. This additional protec-
tion allows the vehicle to be utilized in severe off-road
situations that would be considered impassable by a nor-
mal truck.

STARTING AND OPERATING 457
Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree ramp
without lifting any other wheel off the ground. This
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1,000 is the RTI. This vehicle has
an RTI of 510, which means you can articulate one front
wheel 26 inches (66 cm) in the air while the other three
wheels remain in contact with the ground.
Water Fording Characteristics
Water fording characteristic is the vehicle’s ability to cross
a body of still water, where the powertrain and drivetrain
are safe from water ingestion. This vehicle has high water
fording characteristics with the ability to cross a pool of
water, without stopping, 24 inches (60 cm) deep at a
maximum speed of 10 mph (16 km/h) and a pool of water
30 inches (76 cm) deep at a maximum speed of 5 mph
(8 km/h), both with an entrance ramp angle of 1.3 degrees.
CAUTION!
The door sill height is 25 inches (63.5 cm). Water may
intrude into the interior of the vehicle at greater
depths.
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.
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 isn’t. 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.
458 STARTING AND OPERATING
CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
When To Use Low Range
When driving off-road, shift into 4LO (Low Range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and down
hills, with improved control and less effort. Also, use 4LO
(Low Range) in rain, ice, snow, mud, sand, to get heavy
loads rolling, improve traction, or whenever 4HI (High
Range) traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow – In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4LO (Low Range) 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 ¼
turn quickly back and forth, while still applying throttle.
This will allow the tires to get a fresh biteand help
maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPMs or vehicle speeds because engine brak-
ing may cause skidding and loss of control.
