the AXLE LOCK switch once to lock the rear
axle only (the “Rear Axle Lock Indicator
Light” will illuminate), push the bottom of
the switch again to lock the front axle (the
“Front Axle Lock Indicator Light” will illumi-
nate). When the rear axle is locked, pushing
the bottom of switch again will lock or unlock
the front axle.
NOTE:
The indicator lights will flash until the axles
are fully locked or unlocked.

Electronic Sway Bar Disconnect — If
Equipped
Your vehicle may be equipped with an elec-
tronic disconnecting stabilizer/sway bar. This
system allows greater front suspension travel
in off-road situations.This system is controlled by the SWAY BAR
switch located on the instrument panel (to
the left of the steering column).
Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate
the system. The “Sway Bar Indicator Light”
(located in the instrument cluster) will illumi-
nate when the bar is disconnected. The
“Sway Bar Indicator Light” will flash during
activation transition, or when activation con-ditions are not met. The stabilizer/sway bar
should remain in on-road mode during nor-
mal driving conditions.
WARNING!
Do not disconnect the stabilizer bar and
drive on hardsurfaced 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 neces-
sary 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 or solid “Sway Bar
Indicator Light.” Once vehicle speed is
reduced below 14 mph (22 km/h), the
system will once again attempt to return to
off-road mode.
To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR
switch to obtain the off-road position. Refer
to “Four-Wheel Drive Operation” in this sec-
Sway Bar Switch
133

tion for further information. The “Sway Bar
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 differ-
ences. This condition is due to driving sur-
face 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 on-road mode, push the SWAY
BAR switch again.
WARNING!
If the stabilizer/sway bar will not return to
on-road mode, the “Sway Bar Indicator
Light” will flash in the instrument cluster
and 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
WARNING!
in serious injury. Contact your local autho-
rized dealer for assistance.
STOP/START SYSTEM —

NOTE:
In order to ensure proper operation, the
Speed Control System has been designed toshut down if multiple Speed Control func-
tions are operated at the same time. If this
occurs, the Speed Control System can be
reactivated by pushing the Speed Control
ON/OFF button and resetting the desired ve-
hicle set speed.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
To Activate
Push the ON/OFF button. The Cruise Indica-
tor Light in the instrument cluster display will
illuminate. To turn the system off, push the
ON/OFF button a second time. The Cruise
Indicator Light will turn off. The system
should be turned off when not in use.
WARNING!
Leaving the Speed Control system on when
not in use is dangerous. You could acci-
dentally set the system or cause it to go
faster than you want. You could lose con-
trol and have an accident. Always leave the
system off when you are not using it.
To Set A Desired Speed
Turn the Speed Control on. When the vehicle
has reached the desired speed, push the SET
(-) button and release. Release the accelera-
tor and the vehicle will operate at the se-
lected speed.
NOTE:
The vehicle should be traveling at a steady
speed and on level ground before pushing the
SET (-) button.
To Vary The Speed Setting
To Increase Speed
When the Speed Control is set, you can in-
crease speed by pushing the RES (+) button.

Using Speed Control On Hills
The transmission may downshift on hills to
maintain the vehicle set speed.
NOTE:
The Speed Control system maintains speed
up and down hills. A slight speed change on
moderate hills is normal.
On steep hills, a greater speed loss or gain
may occur so it may be preferable to drive
without Speed Control.
WARNING!
Speed Control can be dangerous where the
system cannot maintain a constant speed.
Your vehicle could go too fast for the con-
ditions, and you could lose control and
have an accident. Do not use Speed Con-
trol in heavy traffic or on roads that are
winding, icy, snow-covered or slippery.
REFUELING THE VEHICLE
Fuel Filler Cap
The fuel filler cap is located on the driver's
side of the vehicle. If the fuel filler cap is lost
or damaged, be sure the replacement cap is
the correct one for this vehicle.
WARNING!
• Never have any smoking materials lit in
or near the vehicle when the gas cap is
removed or the tank is being filled.
• Never add fuel when the engine is run-
ning. This is in violation of most state
fire regulations and may cause the MIL
to turn on.
• A fire may result if gasoline is pumped
into a portable container that is inside of
a vehicle. You could be burned. Always
place gas containers on the ground while
filling.
CAUTION!
• Damage to the fuel system or emission
control system could result from using
an improper fuel filler cap. A poorly
fitting cap could let impurities into the
fuel system. Also, a poorly fitting after-
market cap can cause the “Malfunction
Indicator Light (MIL)” to illuminate, due
to fuel vapors escaping from the system.

CAUTION!
• Automatic transmissions must be
placed in PARK for recreational towing.
• Manual transmissions must be placed in
gear (not in Neutral) for recreational
towing.
• Before recreational towing, perform the
procedure outlined under “Shifting Into
NEUTRAL (N)” to be certain that the
transfer case is fully in NEUTRAL (N).
Otherwise, internal damage will result.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
• Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper
face bar will be damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your
vehicle for recreational towing.
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
position disengages both the front and rear
driveshafts from the powertrain, and will
allow the vehicle to roll, even if the auto-
matic transmission is in PARK (or manual
transmission is in gear). The parking brake
should always be applied when the driver
is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing
to prevent damage to internal parts.
1. Bring the vehicle to a complete stop on
level ground.
2. Press and hold the brake pedal.3. Shift the automatic transmission into
NEUTRAL or depress the clutch pedal on
a manual transmission.
4. Turn the engine OFF.
5. Shift the transfer case lever into NEU-
TRAL (N).
6. Start the engine.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal
on manual transmissions) for five seconds
and ensure that there is no vehicle
movement.
9. Repeat steps seven and eight with auto-
matic transmission in DRIVE or manual
transmission in first gear.
10. Turn the engine OFF and leave the igni-
tion in the unlocked ACC position.
11. Firmly apply the parking brake.
12. Shift the transmission into PARK or
place manual transmission in gear (NOT
in NEUTRAL).
