STARTING AND OPERATING 301
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to turning the key fob to the LOCK position. The
key fob can only be removed from the ignition switch
when the ignition is in the LOCK position and once
removed the shift lever is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
Column Shifter – If Equipped
There is an override for the BTSI that allows you to move
the shift lever out of the PARK position if an electrical
system malfunction occurs (e.g., dead battery).
1. Turn the key fob to the ACC or ON position without
starting the engine.
2. Tilt the steering wheel to the full up position
3. Firmly set the parking brake.
4. Press and maintain firm pressure on the brake pedal.

STARTING AND OPERATING 309
NOTE:Left to right wheel speed difference may be
necessary 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 ve-
hicle 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.

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 Re-
sources 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 andsteering damper. In addition, this vehicle is equipped
with boxed cross members and fore/aft rails. This addi-
tional protection allows the vehicle to be utilized in
severe off-road situations that would be considered im-
passable by a normal truck.
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 655, which means you can articulate one
front wheel 32 inches 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
5
STARTING AND OPERATING 343
high water fording characteristics with the ability to cross
a pool of water, without stopping, 24 inches deep at a
maximum speed of 10 mph (16 km/h) and a pool of
water 30 inches 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. Water may intrude
into the interior of the vehicle at greater depths.
Simultaneous Brake And Throttle Operation
Many off-road driving conditions require the simulta-
neous 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. Control-
ling 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.
344 STARTING AND OPERATING
CAUTION!
Never park your vehicle over dry grass or other
combustible 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 4L (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 4L (Low Range) in rain, ice, snow, mud, sand, to get
heavy loads rolling, improve traction, or whenever 4H
(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 4L (Low Range)
if necessary. Do not shift to a lower gear than neces-
sary 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
