Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the Forward Collision Warning System.
Contact an authorized dealer for service
Úpage 255.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control system is not functioning
properly and service is required. Contact an
authorized dealer.
Sway Bar Fault Warning Light
This light will illuminate when there is a fault in
the sway bar disconnect system Úpage 145.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed. Should one or more tires be in the condition previously
mentioned, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under inflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoid
-
ing sharp braking and steering. If a tire puncture occurs,
repair immediately using the dedicated tire repair kit and
contact an authorized dealer as soon as possible.

CAUTION!
The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inopera -
ble. After using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an authorized
dealer to have your sensor function checked.

144STARTING AND OPERATING
4H PART TIME/4H AUTO TO 4L OR 4L TO 4H
PART TIME/4H AUTO
With the vehicle rolling at 1 to 3 mph (2 to 5 km/h), shift
an automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle
is coasting at 1 to 3 mph (2 to 5 km/h), shift the transfer case lever firmly to the desired position. Do not pause with
the transfer case in N (Neutral). Once the shift is
completed, place the automatic transmission into DRIVE
or release the clutch pedal on a manual transmission.
NOTE:Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty may occur due to
the mating teeth not being properly aligned. Several
attempts may be required for clutch teeth alignment and
shift completion to occur. The preferred method is with the
vehicle rolling at 1 to 3 mph (2 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle
moving faster than 1 to 3 mph (2 to 5 km/h).
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 proportions 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.
AXLE LOCK (TRU-LOK) FRONT AND
R
EAR — IF EQUIPPED
The AXLE LOCK switch is located on the instrument panel
(to the right of the steering column).

Axle Lock Switch Panel

This feature will only activate when the following
conditions are met:

 Vehicle speed should be 10 mph (16 km/h) or less.
 Both right and left wheels on axle are at the same
speed.
To activate the system, push the AXLE LOCK switch down
to lock the rear axle only (the “REAR ONLY” will illuminate),
push the switch up to lock the front axle and rear axle (the
“FRONT + REAR” will illuminate). 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.
To unlock the axles, push the AXLE LOCK OFF button.
Axle Lock will disengage if the vehicle is taken out of 4L, or
the ignition switch is turned to the OFF position.
The Axle Lock disengages at speeds above 30 mph
(48 km/h), and will automatically re-lock once vehicle
speed is less than 10 mph (16 km/h).
AXLE LOCK (TRU-LOK) REAR ONLY —
I
F EQUIPPED
The rear axle may be locked in 4H if the proper conditions
are met.
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not drive
the vehicle unless the transfer case is fully engaged.
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.
WARNING!
This mode is intended for off-highway or off-road use
only and should not be used on any public roadways.

23_JL_OM_EN_USC_t.book Page 144

STARTING AND OPERATING145
The AXLE LOCK switch is located on the instrument panel
(to the right of the steering column).

Axle Lock Switch Panel

This feature will only activate when the following
conditions are met:
Ignition in RUN position, vehicle in 4H.
 The vehicle must be in Off Road+ active
Úpage 146.

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.
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.
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 activate the system. Push
the switch again to deactivate the system. 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 140. 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.
WARNING!
Ensure the stabilizer/sway bar is reconnected before
driving on hard surfaced roads or at speeds above
18 mph (29 km/h); a disconnected stabilizer/sway bar may contribute to the loss of vehicle control, which
could result in serious injury. Under certain
circumstances, the front stabilizer/sway bar enhances
vehicle stability and assists with vehicle control. The
system 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 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.

ELECTRO-HYDRAULIC POWER STEERING
Your vehicle is equipped with an Electro-Hydraulic Power
Steering system that provides increased vehicle response
and ease of maneuverability. The system adapts to
different driving conditions. If the Electro-Hydraulic Power
Steering system experiences a fault that prevents it from
providing power steering assist, then the system will
provide mechanical steering capability.
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 discon -
nected stabilizer/sway bar may contribute to the loss of
vehicle control, which could result in serious injury.

CAUTION!
Extreme steering maneuvers may cause the electrically
driven pump to reduce or stop power steering
assistance in order to prevent damage to the system.
Normal operation will resume once the system is
allowed to cool.

23_JL_OM_EN_USC_t.book Page 146

STARTING AND OPERATING147
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
Úpage 108.
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
Úpage 108.
NOTE:
 Even if power steering assistance is no longer opera -
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM — AUTOMATIC
