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
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.
1 — On Road
2 — Off Road
472 STARTING AND OPERATING
Page 475 of 806

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.
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 or death. The front
stabilizer bar enhances vehicle stability and is nec-
essary for maintaining 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 right hand Off Road stabilizer/sway bar button
to obtain the Off-Road position. The amber indicator
light will flash until the stabilizer/sway bar has been
fully disconnected.
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 left hand On
Road stabilizer/sway bar button .

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 throttle
as 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.

When driving over sand, mud, and other soft terrain,
shift to low gear and drive steadily. Apply the accelerator
slowly to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.

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.

brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESC are in
the “Partial Off” mode. Refer to “Electronic Stability
Control (ESC)” in this section of this manual. This brake
pressure modulation transfers drive torque from slipping
to non-slipping wheels to provide optimal forward trac-
tion.
Brake Assist System (BAS) — If Equipped
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
BAS detects an emergency braking situation by sensing
the rate and amount of brake application and then
applies optimum pressure to the brakes. The system
applies optimum pressure to the brakes in emergency
braking conditions. This can help reduce braking dis-
tances. The BAS complements the ABS. Applying the
brakes very quickly results in the best BAS assistance. Toreceive the benefit of BAS, you must apply continuous
braking pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired.
Once the brake pedal is released, the BAS is deactivated.
WARNING!
•
The BAS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded.
• The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.

In this mode, ESC and TCS except for the “limited slip”
feature described in the TCS section are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h) the system returns to “Partial Off”
mode, described above. When the vehicle speed drops
below 35 mph (56 km/h) the ESC system shuts off. ESC
is off at low vehicle speeds so that it will not interfere
with off-road driving but ESC function returns to provide
the stability feature at speeds above 40 mph (64 km/h).
The “ESC Off Indicator Light” will always be illuminated
when ESC is off. To turn ESC on again, momentarily
press the “ESC Off” switch. This will restore the normal
“ESC On” mode of operation.
“ESC Off” is the only operating mode for ESC in 4WD
LOW. Whenever the vehicle is started in 4WD LOW or
the transfer case (if equipped) is shifted from 4WD LOCK
or NEUTRAL, to 4WD LOW, the ESC system will be in
this mode.WARNING!
In the ESCFull Offmode, the engine torque reduc-
tion and stability features are disabled. Therefore,
the enhanced vehicle stability offered by ESC is
unavailable. In an emergency evasive maneuver the
ESC system will not engage to assist in maintaining
stability. “ESC Off” mode is intended for off-
highway or off-road use only.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If

do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.
