or the ignition switch is turned to the OFF position.
NOTE:The indicator lights will flash until the rear axle is
fully locked or unlocked.
The rear Axle Lock system may temporarily
disengage the rear locker under some conditions.
If this occurs, the rear axle will automatically
re-lock as soon as the system allows.
If an Axle Lock request cannot be completed by the
system within 5 seconds due to vehicle operating
conditions not being correct, the request will be
canceled and the driver may need to re-request the
locker to be activated.
ELECTRONIC SWAY BAR DISCONNECT —
I
F EQUIPPED
Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system
allows greater front suspension travel in off-road
situations.
WARNING!
This mode is intended for off-highway or off-road
use only and should not be used on any public
roadways.

23_JT_OM_EN_USC_t.book Page 166

STARTING AND OPERATING167
This system is controlled by the SWAY BAR switch
located on the instrument panel (to the right of the
steering column).

SWAY BAR Switch

Push the SWAY BAR switch to disconnect or
connect the sway bar. The Sway Bar Indicator Light
(located in the instrument cluster) will illuminate
when the bar is disconnected. The Sway Bar
Indicator Light will flash during activation
transition, or when activation conditions are not
met. The stabilizer/sway bar should remain in
on-road mode during normal driving conditions. To disconnect the stabilizer/sway bar, shift to
either 4H or 4L and push the SWAY BAR switch to
obtain the off-road position
Úpage 161. 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 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 on-road mode, push the SWAY BAR
switch again.WARNING!
Ensure the stabilizer/sway bar is reconnected
before driving on hard surfaced roads or at
speeds above 18 mph (29 km/h); a discon -
nected stabilizer/sway bar may contribute to the
loss of vehicle control, which could result in seri -
ous injury. Under certain circumstances, the
front stabilizer/sway bar enhances vehicle sta -
bility and assists with vehicle control. The sys-
tem monitors vehicle speed and will attempt to
reconnect the stabilizer/sway bar at speeds over
18 mph (29 km/h). This is indicated by a flash -
ing or solid Sway Bar Indicator Light. Once vehi -
cle speed is reduced below 14 mph (22 km/h),
the system will once again attempt to return to
off-road mode.
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 may be reduced. Do not attempt to drive
the vehicle over 18 mph (29 km/h). Driving
faster than 18 mph (29 km/h) with a
disconnected stabilizer/sway bar may contribute
to the loss of vehicle control, which could result
in serious injury.

STARTING AND OPERATING169
If the “SERVICE POWER STEERING”
message and a flashing icon are
displayed on the instrument cluster
screen, it indicates that the vehicle
needs to be taken to an authorized dealer for
service. It is likely the vehicle has lost power
steering assistance Ú page 121.
If the “POWER STEERING HOT” message and an
icon are displayed on the instrument cluster
screen, it indicates that extreme steering
maneuvers may have occurred, which caused an
over temperature condition in the power steering
system. You will lose power steering assistance
momentarily until the over temperature condition
no longer exists. Once driving conditions are safe,
pull over and let vehicle idle for a few moments
until the light turns off Ú page 121.
NOTE:
Even if power steering assistance is no longer
operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -cially at very low vehicle speeds and during
parking maneuvers.
If the condition persists, see an authorized
dealer for service.
STOP/START SYSTEM — AUTOMATIC
TRANSMISSION (IF EQUIPPED)
The Engine Stop/Start (ESS) function is developed
to reduce fuel consumption. The system will stop
the engine automatically during a vehicle stop if
the required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal will
automatically restart the engine.
ESS vehicles have been upgraded with a
heavy-duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
NOTE:It is recommended that the Stop/Start system be
disabled during off-road use.
Secondary Battery
Your vehicle may be equipped with a secondary
battery used to power the Stop/Start system and
the 12 Volt vehicle electrical system. The
secondary battery is located behind the wheel well
for the front passenger wheel.

CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
When engaged, the Cruise Control system takes
over accelerator operations at speeds greater than
20 mph (32 km/h).
The Cruise Control buttons are located on the right
side of the steering wheel.

To Activate
Push the on/off button to activate the Cruise
Control. The cruise indicator 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.
To Set A Desired Speed
Turn the Cruise Control on.
NOTE:The vehicle should be traveling at a steady speed
and on level ground before pushing the SET (+) or
SET (-) button.
When the vehicle has reached the desired speed,
push the SET (+) or SET (-) button and release.
Release the accelerator and the vehicle will
operate at the selected speed.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each

WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.
WARNING!
Leaving the Cruise Control system on when not
in use is dangerous. You could accidentally set
the system or cause it to go faster than you
want. You could lose control and have an
accident. Always ensure the system is off when
you are not using it.

23_JT_OM_EN_USC_t.book Page 174

STARTING AND OPERATING175
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise 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 Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANC
(cancel) button, or normal brake pressure while
slowing the vehicle will deactivate the Cruise
Control without erasing the set speed from
memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Clutch pedal is pressed (manual transmission
only)
Vehicle is operating at a low RPM (manual trans -
mission only)
Pushing the on/off button or placing the ignition in
the OFF position, erases the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently if your vehicle is not equipped
with ACC Ú page 173.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward-facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 432.
WARNING!
Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on
roads that are winding, icy, snow-covered or
slippery.

23_JT_OM_EN_USC_t.book Page 175

STARTING AND OPERATING179
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is
being used.
Resume can be used at any speed above 0 mph
(0 km/h) when ACC is active.
NOTE:
While in ACC mode when the vehicle comes to a
complete stop longer than two seconds, the
system will cancel. The driver will have to apply
the brakes to keep the vehicle at a standstill.
ACC cannot be resumed if there is a stationary
vehicle in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set
speed by pushing the SET (+) button, or decrease
speed by pushing the SET (-) button.
U.S. Speed (mph)
Pushing the SET (+) , or SET (-) button once will
result in a 1 mph speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 mph.
If the button is continually pushed, the set
speed will continue to adjust in 5 mph incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust in 10 km/h incre -
ments until the button is released. The new set
speed is reflected in the instrument cluster
display.
NOTE:When you override and push the SET (+) or SET (-)
button, the new set speed will be the current speed
of the vehicle.
When ACC Is Active
When you use the SET (-) button to decelerate, if
the engine’s braking power does not slow the
vehicle sufficiently to reach the set speed, the
brake system will automatically slow the
vehicle.
The ACC system applies the brake down to a full
stop when following a vehicle in front. If your
vehicle follows a vehicle ahead to a standstill,
your vehicle brakes will release two seconds
after coming to a full stop.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while climbing
uphill or descending downhill. This is normal
operation and necessary to maintain set speed.
When driving uphill and downhill, the ACC
system will cancel if the braking temperature
exceeds normal range (overheated).
WARNING!
The Resume function should only be used if
traffic and road conditions permit. Resuming a
set speed that is too high or too low for
prevailing traffic and road conditions could
cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or
serious personal injury.
