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 Off⬙ and ⬙ESC full Off⬙.

WARNING!

With the ESC in

ⴖESC Full Offⴖ mode, 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

ⴖESC Full Offⴖ

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 into

⬙ESC Partial Off⬙

When 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 Off⬙ at 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

⬙ or ⬙ESC 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

ⴖESC Full Offⴖ mode, 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

ⴖESC Full Offⴖ

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 On⬙ mode of operation.

NOTE:

To improve the vehicle’s traction when driving

with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the

⬙ESC Partial Off⬙

mode by pushing the

⬙ESC Full Off⬙ switch. Once the

situation requiring ESC to be switched to the

⬙ESC Partial

Off

⬙ mode is overcome, turn ESC back on by momentarily

pushing the

⬙ESC Full Off⬙ switch. This may be done while

the vehicle is in motion.

The ESC will restore to normal ESC On mode after each
key on.

SAFETY

WARNING!

• When in “Partial Off” mode, the TCS functionality

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. When in
“Partial Off” mode, the engine power reduction
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.

• Trailer Sway Control (TSC) is disabled when the ESC

system is in the

ⴖPartial Offⴖ mode.

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 to the ON mode. It
should go out with the engine running. If the

“ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than

30 mph (48 km/h), see your authorized dealer as soon as
possible to have the problem diagnosed and corrected.

The “ESC Activation/Malfunction Indicator Light” (located in
the instrument cluster) starts to flash as soon as the tires lose
traction 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 conditions.

NOTE:
• The “ESC Activation/Malfunction Indicator Light” and

the “ESC OFF Indicator Light” come on momentarily
each time the ignition is turned ON.

• Each time the ignition is turned ON, the ESC system will

be on even if it was turned off previously.

• The ESC system will make buzzing or clicking sounds

when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.

SAFETY

213

The “ESC OFF Indicator Light” indicates the
customer has elected to have the Electronic Sta-
bility Control (ESC) in a reduced mode.

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 vehicle’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.

NOTE:

ERM is disabled anytime the ESC is in “Full Off”

mode (if equipped). Refer to “Electronic Stability Control
(ESC)” in this section for a complete explanation of the
available ESC modes.

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 ve-
hicles. The capabilities of an ERM-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or the
safety of others.

Trailer Sway Control (TSC)

TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati-
cally once an excessively swaying trailer is recognized.

NOTE:

TSC cannot stop all trailers from swaying. Always

use caution when towing a trailer and follow the trailer
tongue weight recommendations. Refer to “Trailer Tow-
ing” in “Starting And Operating” for further information.

214

SAFETY

When

TSC

functioning,

the

“ESC Activation/

Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being applied
to individual wheels to attempt to stop the trailer from
swaying. TSC is disabled when the ESC system is in the
“Partial Off” or “Full Off” modes.

WARNING!

If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

Hill Descent Control (HDC) — If Equipped

HDC is only intended for low speed off-road driving. HDC
maintains vehicle speed while descending hills in off-road
driving conditions by applying the brakes when necessary.

The symbol indicates the status of the Hill De-
scent Control (HDC) feature. The lamp will be on
solid when HDC is armed. HDC can only be
armed when the transfer case is in the “4WD

LOW” position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while attempting
to use the HDC feature, the HDC indicator light will flash
on/off.

When enabled, HDC senses the terrain and activates when
the vehicle is descending a hill. HDC speed may be
adjusted by the driver to suit the driving conditions. The
speed corresponds to the transmission gear selected.

SAFETY

However, the driver can override HDC operation by
applying the brake to slow the vehicle down below the
HDC control speed. If more speed is desired during HDC
control, the accelerator pedal will increase vehicle speed in
the usual manner. When either the brake or the accelerator
is released, HDC will control the vehicle at the original set
speed.

Enabling HDC

1. Shift the transfer case into 4WD LOW range. Refer to

“Four-Wheel Drive Operation” in “Starting and Oper-
ating” for further information.

2. Push the “Hill Descent” button. The “Hill Descent

Control Indicator Light” in the instrument cluster will
turn on solid.

NOTE:

• If the transfer case is not in 4WD LOW range, the “Hill

Descent Control Indicator Light” will flash for five
seconds and HDC will not be enabled.

• If the ESC senses that the brakes are overheating the

“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.

Disabling HDC

Push the “Hill Descent” button or shift the transfer case out
of 4WD LOW range. The “Hill Descent Control Indicator”
light in the instrument cluster will turn off.

SAFETY

AUXILIARY DRIVING SYSTEMS

Tire Pressure Monitor System (TPMS)

The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.

The tire pressure will vary with temperature by about 1 psi
(7.0 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after a vehicle has not been driven for more than three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires” in “Servicing and Maintenance” for
information on how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the vehicle is driven;
this is normal and there should be no adjustment for this
increased pressure.

The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural pressure loss through the tire.

The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn

off until the tire pressure is at or above recommended cold
placard pressure. Once the “Tire Pressure Monitoring Tell-
tale Light” has been illuminated, the tire pressure must be
increased to the recommended cold placard pressure in
order for the “Tire Pressure Monitoring Telltale Light” to be
turned 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 placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.

The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.

For example, your vehicle may have a recommended cold
(parked for more than three hours) air pressure of 35 psi
(241 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 30 psi (207 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to
approximately 26 psi (179 kPa). This tire pressure is suffi-
ciently low enough to turn ON the “Tire Pressure Moni-
toring Telltale Light.” Driving the vehicle may cause the
tire pressure to rise to approximately 30 psi (207 kPa), but

SAFETY

217

the “Tire Pressure Monitoring Telltale Light” will still be
ON. In this situation, the “Tire Pressure Monitoring Telltale
Light” will turn OFF only after the tires have been inflated
to the vehicle’s recommended cold placard pressure value.

CAUTION!

• The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed
for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.

• Using aftermarket tire sealants may cause the Tire

Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealership to have your sensor
function checked.

(Continued)

CAUTION! (Continued)

• After inspecting or adjusting the tire pressure, al-

ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.

NOTE:
• The TPMS is not intended to replace normal tire care and

maintenance, nor to provide warning of a tire failure or
condition.

• The TPMS should not be used as a tire pressure gauge

while adjusting your tire pressure.

• Driving on a significantly under-inflated tire causes the

tire to overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stopping
ability.

• The TPMS is not a substitute for proper tire mainte-

nance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the “Tire
Pressure Monitoring Telltale Light.”

218

SAFETY

• 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 your tires regularly and to maintain the
proper pressure.

The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light

A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size spare

tire can be used in place of any of the four road tires. A low
spare tire will not cause the “Tire Pressure Monitoring
Telltale Light” to illuminate or the chime to sound while
stowed in the spare location.

The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE

PRESSURE” message will display in the instrument cluster,
and an audible chime will be activated when one or more
of the four active road tire pressures are low. 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 recommended cold placard pres-
sure value. The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will extinguish
once the updated tire pressures have been received. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.

The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and will remain on solid when a
system fault is detected. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. The “Tire

SAFETY

219

Pressure Monitoring Telltale Light” will turn off when the
fault condition no longer exists. A system fault can occur by
any of the following scenarios:

1. Jamming due to electronic devices or driving next to

facilities emitting the same Radio Frequencies as the
TPM sensors.

2. Installing some form of aftermarket window tinting that

affects radio wave signals.

3. Lots of snow or ice around the wheels or wheel hous-

ings.

4. Using tire chains on the vehicle.

5. Using wheels/tires not equipped with TPM sensors.

Vehicles not equipped with instrument cluster display will
inform the driver which tire(s) are low but not provide
actual tire pressure. The low tire ISO telltale will illuminate
along with “LoTIrE” message displayed in the ODO and
then it will scroll to which tire location is lower than the
Placard Value.

Tire location will be displayed as follows:

LF = Left Front

rF = right Front

Lr = Left rear

rr = right rear

NOTE:
• If your vehicle is equipped with a matching full-size

spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS) when swapped
with a low pressure road tire. In the event that the
matching full-size spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the “Tire Pressure Monitoring Telltale Light” to be
ON, and a chime to sound. Driving the vehicle for up to
20 minutes above 15 mph (24 km/h) will turn OFF the
“Tire Pressure Monitoring Telltale Light” as long as none
of the road tires are below the low pressure warning
threshold.

• If your vehicle is not equipped with a matching full-size

spare wheel and tire assembly, it does not have a tire
pressure monitoring sensor in the spare tire. The TPMS
will not be able to monitor the tire pressure. If you install
the spare tire in place of a road tire that has a pressure
below the low-pressure warning limit, upon the next
ignition key cycle, a chime will sound and the “Tire
Pressure Monitoring Telltale Light” will turn ON. After

220

SAFETY

driving the vehicle for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid. For each subsequent ignition key cycle, a chime
will sound and the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid. Once you repair or replace the original
road tire, and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automatically and the
“Tire Pressure Monitoring Telltale Light” will turn OFF,
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 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.

SAFETY

TPMS Deactivation — If Equipped

The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies 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 Monitoring (TPM) Sensors. Then, drive the
vehicle for 20 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 remain on. The instrument cluster will
display 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 20 minutes above
15 mph (24 km/h). The TPMS will chime, the

⬙TPM Telltale

OCCUPANT RESTRAINT SYSTEMS

Some of the most important safety features in your vehicle
are the restraint systems:

SAFETY

225

Occupant Restraint Systems Features

• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air Bags
• Child Restraints
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask your autho-
rized dealer.

Important Safety Precautions

Please pay close attention to the information in this section.
It tells you how to use your restraint system properly, to
keep you and your passengers as safe as possible.

Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride

buckled up in a vehicle with a rear seat.

2. If a child from 2 to 12 years old (not in a rear-facing child

restraint) must ride in the front passenger seat, move the
seat as far back as possible and use the proper child
restraint (refer to “Child Restraints” in this section for
further information).

3. Children that are not big enough to wear the vehicle seat

belt properly (refer to “Child Restraints” in this section
for further information) should be secured in a vehicle
with a rear seat in child restraints or belt-positioning
booster seats. Older children who do not use child
restraints or belt-positioning booster seats should ride
properly buckled up in a vehicle with a rear seat.

4. Never allow children to slide the shoulder belt behind

them or under their arm.

5. You should read the instructions provided with your

child restraint to make sure that you are using it
properly.

6. All occupants should always wear their lap and shoul-

der belts properly.

7. The driver and front passenger seats should be moved

back as far as practical to allow the front air bags room
to inflate.

8. Do not lean against the door or window. If your vehicle

has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between occu-
pants and the door and occupants could be injured.
