GETTING TO KNOW YOUR INSTRUMENT PANEL137
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 291.
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.
Sway Bar Fault Warning Light —
If Equipped
This light will illuminate when there is a
fault in the sway bar disconnect system
Úpage 166.
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 life 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 underinflated 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.
WARNING!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding 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.

STARTING AND OPERATING165
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).
During cold weather, you may experience
increased effort in shifting until the transfer case
fluid warms up. This is normal.
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:
Ignition in ON/RUN position, vehicle in 4L
(Four-Wheel Drive Low Range).
Vehicle speed should be 10 mph (16 km/h) or
less.
Both right and left wheels on axle are at the
same speed.
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.

(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. 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
(Four-Wheel Drive High Range).
The vehicle must be in OFF ROAD+ active
Ú page 168.
Vehicle must be in ESC “Full Off” mode
Úpage 282.
Vehicle must not be actively in a high wheel slip
or tight cornering condition.
To activate the system, push the AXLE LOCK switch
down to lock the rear axle only (“REAR ONLY” will
illuminate). To unlock the rear axle, push the AXLE LOCK OFF
button.
Axle Lock will disengage if the vehicle is taken out
of 4H (Four-Wheel Drive High Range), OFF ROAD+
is turned off by the driver, ESC “Full Off” is exited,
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.

ELECTRO-HYDRAULIC POWER STEERING
Your vehicle is equipped with an Electro-Hydraulic
Power Steering system that will provide increased
vehicle response and ease of maneuverability. 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.

23_JT_OM_EN_USC_t.book Page 168

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.
