flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
hicle 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 replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion 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!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when

market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to your authorized dealer to have your
sensor function checked.
— Towing Hook Breakdown Warning
Light — If Equipped
This light illuminates when there is a failure
with the tow hook. Contact your authorized
dealer for service.
— Vehicle Security Warning Light
This telltale will illuminate when the vehicle
security alarm system has detected an at-
tempt was made to break into the vehicle.
Yellow Indicator Lights
— 4WD Lock Indicator Light
This light alerts the driver that the vehicle is
in the four-wheel drive LOCK mode. The front
and rear driveshafts are mechanically locked
together, forcing the front and rear wheels to
rotate at the same speed.
Refer to “Four-Wheel Drive Operation” in
“Starting And Operating” for further informa-
tion on four-wheel drive operation and proper
use.
— 4WD Low Indicator Light — If
Equipped
This light alerts the driver that the vehicle is
in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide in-
creased torque at the wheels.
Refer to “Four-Wheel Drive Operation — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive op-
eration and proper use.

SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to en-
sure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight clicking
sound as well as some related motor noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s).
You also may experience the following when
ABS activates:
• The ABS motor noise (it may continue to
run for a short time after the stop).
• The clicking sound of solenoid valves.• Brake pedal pulsations.
• A slight drop of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.
WARNING!
• The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by improp-
erly installed or high output radio
transmitting equipment. This interfer-
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by
qualified professionals.
• Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.
• The ABS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase braking or steering
efficiency beyond that afforded by the
WARNING!
condition of the vehicle brakes and tires
or the traction afforded.
• The ABS cannot prevent collisions, in-
cluding those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
• The capabilities of an ABS equipped
vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.
ABS is designed to function with the OEM
tires. Modification may result in degraded
ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake 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 “Anti-Lock Brake Warning Light” re-
mains on or comes on while driving, it indi-
cates that the anti-lock portion of the brake
system is not functioning and that service is
SAFETY

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 required. 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.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and Electric Power Steering (EPS) mod-
ules that provides torque at the steering
wheel for certain driving conditions in which
the ESC module is detecting vehicle instabil-
ity. The torque that the steering wheel re-
ceives is only meant to help the driver realize
optimal steering behavior in order to reach/maintain vehicle stability. The only notifica-
tion the driver receives that the feature is
active is the torque applied to the steering
wheel.
NOTE:
The DST feature is only meant to help the
driver realize the correct course of action
through small torques on the steering wheel,
which means the effectiveness of the DST
feature is highly dependent on the driver’s
sensitivity and overall reaction to the applied
torque. It is very important to realize that this
feature will not steer the vehicle, meaning
the driver is still responsible for steering the
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 be-
fore the front axle.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for
wheel lift by monitoring the driver’s steering
wheel input and the speed of the vehicle.
When ERM determines that the rate of
change of the steering wheel angle and vehi-
cle’s speed are sufficient to potentially cause
wheel lift, it then applies the appropriate
brake and may also reduce engine power to
lessen the chance that wheel lift will occur.
ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving
maneuvers; it cannot prevent wheel lift due
to other factors, such as road conditions,
leaving the roadway, or striking objects or
other vehicles.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent
all wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities

Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or
off-road use when ESC stability features
could inhibit vehicle maneuverability due to
trail conditions. This mode is entered by
pushing and holding the “ESC Off” switch for
five seconds when the vehicle is stopped and
the engine is running. After five seconds, the
"ESC OFF Indicator Light" will illuminate and
the “ESC OFF” message will appear in the
instrument cluster display.
In this mode, ESC and TCS, except for the
“limited slip” feature described in the TCS
section, are turned off until the vehicle
reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h), the system returns to
“Partial Off” mode, as described above. TCS
remains off. When the vehicle speed drops
below 30 mph (48 km/h), the ESC system
shuts off. ESC is deactivated at low vehicle
speeds so that it will not interfere with off-
road driving however, 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 when ESC is
off.To turn ESC on again, momentarily push the
“ESC Off” switch. This will restore the “ESC
On” mode of operation.
NOTE:
The “ESC OFF” message will display and an
audible chime will sound when the gear se-
lector is placed into 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!
In the "Full Off" mode, the engine torque
reduction and stability features are disabled.
In an emergency evasive maneuver, the ESC
system will not engage to assist in maintain-
ing stability. “ESC Off” mode is intended for
off-highway or off-road use only.
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The “ESC Activation/
Malfunction Indicator Light” in
the instrument cluster will come
on when the ignition is turned tothe ON mode. It should go out with the
engine running. If the “ESC Activation/
Malfunction Indicator Light” comes on con-
tinuously with the engine running, a malfunc-
tion has been detected in the ESC system. If
this light remains on after several ignition
cycles, and the vehicle has been driven sev-
eral miles (kilometers) at speeds greater than
30 mph (48 km/h), see your authorized
dealer as soon as possible to have the prob-
lem diagnosed and corrected.
The “ESC Activation/Malfunction Indicator
Light” (located in the instrument cluster)
starts to flash as soon as the tires lose trac-
tion and the ESC system becomes active. The
“ESC Activation/Malfunction Indicator
Light” also flashes when TCS is active. If the
“ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration,
ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your
speed and driving to the prevailing road con-
ditions.

• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
Base System
The Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the receiver module.
NOTE:
It is particularly important for you to check
the tire pressure in all of the tires on your
vehicle monthly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The “Tire Pressure Monitoring Tell-
tale Light” will illuminate in the in-
strument cluster, a “LOW TIRE
PRESSURE” message will display in the in-
strument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. Should this occur, you
should stop as soon as possible, check the
inflation pressure of each tire on your vehicle,
and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, the system will automatically update
and the “Tire Pressure Monitoring Telltale
Light” will turn off.NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The vehicle may
need to be driven for up to 10 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a
chime. If the ignition is cycled, this sequence
will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale
Light” will turn off when the fault condition
no longer exists. A system fault can occur due
to any of the following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.

• Lots of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with
TPMS sensors.
Vehicles With Compact Spare or non-Matching
Full Size Spare
1. The compact spare tire or non-matching
full size spare tire does not have a tire
pressure monitoring sensor. Therefore,
the TPMS will not monitor the pressure in
the spare tire.
2. If you install the compact or non-
matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, a chime will
sound and the “TPMS Telltale Light” and
“LOW TIRE PRESSURE” message will
turn on upon the next ignition cycle.
3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid.4. For each subsequent ignition cycle, a
chime will sound and the “TPMS Telltale
Light” will flash on and off for 75 seconds
and then remain on solid.
5. Once you repair or replace the original
road tire and reinstall it on the vehicle in
place of the compact spare, the TPMS will
update automatically and the “TPMS Tell-
tale Light” will turn off, as long as no tire
pressure is below the low-pressure warn-
ing limit in any of the four active road
tires. The vehicle may need to be driven
for up to 10 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.

3. After driving the vehicle for up to 10 min-
utes above 15 mph (24 km/h), the “TPMS
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, the instrument cluster will dis-
play a “SERVICE TPM SYSTEM” message
for five seconds and then display dashes
(- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a
chime will sound, the “TPMS Telltale
Light” will flash on and off for 75 seconds
and then remain on solid, and the instru-
ment cluster will display a “SERVICE
TPM SYSTEM” message for five seconds
and then display dashes (- -) in place of
the pressure value.
5. Once you repair or replace the original
road tire and reinstall it on the vehicle in
place of the compact spare, the TPMS will
update automatically. In addition, the
“TPMS Telltale Light” will turn off and the
graphic in the instrument cluster will dis-play a new pressure value instead of
dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in
any of the four active road tires. The
vehicle may need to be driven for up to
10 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this
information.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires)
with wheel and tire assemblies that do not
have TPMS Sensors, such as when installing
winter wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all four
wheel and tire assemblies (road tires) with
tires not equipped with Tire Pressure Moni-
toring (TPM) Sensors. Then, drive the vehicle
for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the "TPM Telltale Light"
will flash on and off for 75 seconds and thenremain on. The instrument cluster will dis-
play the “SERVICE TPM SYSTEM” message
and then display dashes (--) in place of the
pressure values.
Beginning with the next ignition cycle, the
TPMS will no longer chime or display the
“SERVICE TPM SYSTEM” message in the
instrument cluster but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires) with
tires equipped with TPM sensors. Then, drive
the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the
"TPM Telltale Light" will flash on and off for
75 seconds and then turn off. The instrument
cluster will display the “SERVICE TPM SYS-
TEM” message and then display pressure
values in place of the dashes. On the next
ignition cycle the "SERVICE TPM SYSTEM"
message will no longer be displayed as long
as no system fault exists.
