94 GETTING TO KNOW YOUR VEHICLE

Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition is turned to the ON/RUN mode and may stay
on for as long as four seconds.
If the “Brake System Warning Light” remains on or comes
on while driving, it indicates that the brake system is not
functioning properly and that immediate service is re-
quired. If the “Brake System Warning Light” does not come
on when the ignition is turned to the ON/RUN mode, have
the light repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The sys-
tem detects an emergency braking situation by sensing the
rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the anti-lockbrake system (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure
during the stopping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released, the BAS is
deactivated.
WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. BAS cannot prevent collisions, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. The capa-
bilities of a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of
others.
Hill Start Assist (HSA)
The HSA system is designed to mitigate roll back from a
complete stop while on an incline. If the driver releases the
brake while stopped on an incline, HSA will continue to
hold the brake pressure for a short period. If the driver
216 SAFETY

For vehicles not equipped with an instrument cluster
display, perform the following steps:
1. Center the steering wheel (front wheels pointingstraight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than one-half turn to the left.
6. Push the “ESC Off” button located in the lower switch bank below the climate control four times within 20
seconds. The “ESC Off Indicator Light” should turn on
and turn off two times.
7. Rotate the steering wheel back to center and then an additional slightly more than one-half turn to the right.
8. Turn the ignition to the OFF mode and then back to ON. If the sequence was completed properly, the “ESC Off
Indicator Light” will blink several times to confirm HSA
is disabled.
9. Repeat these steps if you want to return this feature to its previous setting.Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counteract-
ing the over/under steer condition. Engine power may also
be reduced to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
218 SAFETY

ESC Full Off
This mode is entered by pushing and holding the ESC OFF
switch for five seconds.
In theESC Full Off mode, the engine torque reduction
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 Full Off”
mode is intended for off-highway or off-road use only. When in
ESC Full Off mode, ESC and TCS, except for the
Brake Limited Differential (BLD) feature described in the
TCS section, are turned off until the vehicle reaches an
approximate speed of 40 mph (64 km/h). For speeds at or
exceeding approximately 40 mph (64 km/h) the ESC goes
into ESC Partial Off. When the vehicle speed drops below
35 mph (56 km/h), the ESC system goes back to ESC Full
Off. To turn ESC on again, momentarily push the ESC OFF
switch. This will restore normal “ESC On” mode of opera-
tion. The ESC Off Indicator Light” will always be illumi-
nated when ESC is in ESC Partial OffandESC full Off.
WARNING!
With the ESC in ESC Full Offmode, the engine
torque reduction and stability features offered by ESC
and ERM are disabled. In an emergency evasive ma-
neuver, the ESC and ERM systems will not engage to
assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.

4L Range (4WD Models)
ESC Full Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the transfer
case (if equipped) is shifted from 4H range or NEUTRAL to
4L range, the ESC system will be in this mode. In 4L range,
ESC and TCS, except for the Brake Limited Differential (BLD)
feature described in the TCS section, are turned off until the
vehicle reaches an approximate speed of 40 mph (64 km/h).
For speeds at or exceeding approximately 40 mph (64 km/h)
the ESC goes intoESC Partial OffWhen the vehicle speed
drops below 35 mph (56 km/h), the ESC system goes back to
ESC Full Off. The ESC is in ESC Full Offat low vehicle
speeds in 4L range so that it will not interfere with off-road
driving, but the 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 in 4L range when
ESC is in ESC Full Off orESC Partial Off.
NOTE:The “ESC OFF” message will display and an audible
chime will sound when the gear selector is placed in the
PARK position from any other position, and then moved out
of the PARK position. This will occur even if the message was
previously cleared.
WARNING!
With the ESC in ESC Full Offmode, the engine
torque reduction and stability features offered by ESC
and ERM are disabled. In an emergency evasive ma-
neuver, the ESC and ERM systems will not engage to
assist in maintaining stability. The ESC Full Off
mode is intended for off-road use only.
2H Range (4WD Models) Or 2WD Models
ESC On
This is the normal operating mode for ESC in 2H range and
on 2WD vehicles.
ESC Partial Off
When in ESC Partial Off mode, the TCS portion of ESC
(except for the limited slip feature described in the TCS
section), has been disabled and the ESC Off Indicator
Light will be illuminated.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal ESC Onmode of operation.
222 SAFETY

Trac-Lok Rear Axle — If Equipped
The Trac-Lok rear axle provides a constant driving force to
both rear wheels and reduces wheel spin caused by the loss
of traction at one driving wheel. If traction differs between
the two rear wheels, the differential automatically propor-
tions the usable torque by providing more torque to the
wheel that has traction.
Trac-Lok is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maximum
traction.
WARNING!
On vehicles equipped with a limited-slip differential,
never run the engine with one rear wheel off the
ground. The vehicle may drive through the rear wheel
remaining on the ground and cause you to lose control
of your vehicle.
Axle Lock (Tru–Lok) — Rubicon Models
The AXLE LOCK switch is located on the instrument panel
(to the left of the steering column).This feature will only activate when the following condi-
tions are met:
•
Key in ignition, vehicle in 4L (Low) range.
• Vehicle speed should be 10 mph (16 km/h) or less.
To activate the system, push the bottom of 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 illuminate). When the rear axle is
locked, pushing the bottom of switch again will lock or
unlock the front axle.

STARTING AND OPERATING 305

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 stabi-
lizer 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
section 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 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 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 re-
duced. 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 authorized dealer
for assistance.

STARTING AND OPERATING 307

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.
• 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.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.
