If all the requirements to select a new transfer case
position have been met, the current “Transfer Case
Position Indicator Light” will turn OFF, the selected
“Transfer Case Position Indicator Light” will flash
until the transfer case completes the shift. When the
shift is completed, the “Transfer Case Position Indica-
tor Light” for the selected position will stop flashing
and remain ON.
2WD⇔4WD LOCKRotate the transfer case switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after turn-
ing the switch. If the vehicle is stopped, the ignition key
must be in the ON position with the engine either
running or off. This shift cannot be completed if the key
is in the ACC position. NOTE:
The transfer case will not allow shifts between
2WD and 4WD LOCK if the front and/or rear wheels are
spinning (no traction). In this situation, the selected
“Transfer Case Position Indicator Light” will flash and
the original “Transfer Case Position Indicator Light” will
remain ON. At this time, reduce speed and stop spinning
the wheels to complete the shift.
2WD or 4WD LOCK⇔ 4WD LOWNOTE:When shifting into or out of 4WD LOW some
gear noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With engine running, slow the vehicle to 2 to 3 mph (3
to 5 km/h).

2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the transfer case switch to the
desired position.
4. After the desired “Transfer Case Position Indicator
Light” is ON (not flashing), shift the transmission back
into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the key ON and the engine either OFF or
running, shift the transmission into NEUTRAL.
3. Rotate the transfer case switch into the desired posi-
tion.
4. After the desired “Transfer Case Position Indicator
Light” is ON (not flashing), shift the transmission back
into gear.NOTE:
•
If steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the
shift, the desired “Transfer Case Position Indicator
Light” will flash continuously while the original
“Transfer Case Position Indicator Light” is ON, until
all requirements have been met.
•
The ignition key must be ON for a shift to take place
and for the “Transfer Case Position Indicator Lights”
to be operable. If the key is not ON then the shift will
not take place and no “Transfer Case Position Indica-
tor Lights” will be on or flashing.

21 days, refer to the section on “Vehicle Storage.”
278 STARTING AND OPERATING

The locking axles are controlled by the axle locker switch
located on the center console.
The switch has three positions, AXLE UNLOCK, REAR
LOCK, and FRONT/REAR LOCK. Under normal driv-
ing conditions, the switch should be left in the AXLE
UNLOCK position. In the AXLE UNLOCK position, thefront and rear axles are unlocked. In the REAR LOCK
position, the rear axle is locked. In the FRONT/REAR
LOCK position, the front and rear axles are locked.
NOTE:
Even when the axles are in the AXLE UNLOCK
position, the limited slip differential in the rear axle still
provides torque biasing capability for moderate low
traction environments.
During the command to lock the axle, the indicator light
will flash until the axle is locked. After the lock command
has been successfully executed, the light will remain on
solid.
To lock the rear axle, place the vehicle in 4LO. Refer to
“Four Wheel Drive Operation” in this section of the
manual. Move the axle locker switch 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.
Locking Axle Switch
280 STARTING AND OPERATING

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 an accident 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 ONLYYour vehicle is equipped with an electronic disconnecting
stabilizer/sway bar. This system allows greater front
suspension 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.
This system is controlled by the electronic control sway
bar switch located on the instrument panel.The switch has two positions; On-Road and Off-Road.
The system is normally in the On-Road mode, indicated
by a solid green light. The stabilizer/sway bar should
remain in the On-Road mode during normal driving
conditions.
1 — On Road
2 — Off Road
282 STARTING AND OPERATING

WARNING!
Do not disconnect the stabilizer bar and drive on
hard surfaced roads or at speeds above 18 mph
(29 km/h), you may lose control of the vehicle, which
could result in serious injury. The front stabilizer bar
enhances vehicle stability and is necessary for main-
taining control of the vehicle. The system monitors
vehicle speed and will attempt to reconnect the
stabilizer bar at speeds over 18 mph (29 km/h). This is
indicated by a flashing off road light and solid on
road light. Once vehicle speed is reduced below
14 mph (22 km/h), the system will attempt to return to
the Off-Road mode.
To disconnect the stabilizer/sway bar, shift to either 4HI
or 4LO as shown in “Four Wheel Drive Operation” and
press the top of the stabilizer/sway bar button to obtain the Off-Road position. The amber indicator light will
flash until the stabilizer/sway bar has been fully discon-
nected.
NOTE:
The stabilizer/sway bar may be torque locked
due to left and right suspension height differences. This
condition 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; press the bottom of the
stabilizer/sway bar button.
STARTING AND OPERATING 283

WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is greatly 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. Contact your local service center for
assistance.SAFE OFF-ROAD DRIVING — POWER WAGON

Off-Road Driving Tips and Vehicle CharacteristicsYour 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 youventure 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 ProtectionSteel 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 addi-
tional protection allows the vehicle to be utilized in
severe off-road situations that would be considered im-
passable by a normal truck.
284 STARTING AND OPERATING

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 DrivingYou 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 interrain. The key is to plan your future driving route while
remembering what you are currently driving over.
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 RangeWhen 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
288 STARTING AND OPERATING

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.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of
your vehicle.Using a SpotterThere 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 RocksWhen 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 RutWhen 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.Crossing LogsTo cross a log, approach it at a slight angle (approxi-
mately 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 andaccelerator to avoid spinning the log out from under your
tires. Then ease the vehicle off the log using your brakes.
CAUTION!
Do not attempt to cross a log with a greater diameter
than the running ground clearance or the vehicle will
become high centered.Getting High CenteredIf 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. Depend-
ing 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.
