they may need to perform a sensor alignment.
Lower Front Fascia Installation
NOTE: This will only work if you have a helper.
1. Starting at the center of the vehicle, engage a sufficient number of tabs to support the weight of the lower
fascia (typically one or two tabs) into the upper fascia.
2. Working your way outward, engage the tabs into the slots on one side of the vehicle.
3. Return to the center of the vehicle and repeat Step 2 to the opposite side of the vehicle. NOTE:
•It may be necessary to apply additional force to
individual tabs to make sure they are fully engaged.
• Do not use any tools to apply additional force to the
tabs as damage to the upper and lower fascias may
result.
4. Reinstall the seven quarter turn fasteners.
Quadra-Lift — If Equipped
When off-roading, it is recommended that the lowest
useable vehicle height that will clear the current obstacle
or terrain be selected. The vehicle height should then be
raised as required by the changes in terrain.
The Selec-Terrain switch will automatically change the
vehicle to the optimized height based on the Selec-
Terrain switch position. The vehicle height can be
changed from the default height for each Selec-Terrain

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differ-
ential (BLD), functions similar to a limited slip differen-
tial and controls the wheel spin across a driven axle. If
one wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the spinning
wheel. This will allow more engine torque to be applied
to the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced mode.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for oversteering or understeering of the vehicle by
applying the brake of the appropriate wheel(s) to assist incounteracting the oversteer or understeer condition. En-
gine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•
Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” lo-
cated in the instrument cluster will start to flash as soon
as the ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the TCS
is active. If the “ESC Activation/Malfunction Indicator

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 condi-
tions 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 of an ERM-
equipped vehicle must never be exploited in a reck-
less 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 exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will become
active automatically once an excessively swaying trailer
is recognized. Note that TSC cannot stop all trailers from
520 STARTING AND OPERATING

For example, your vehicle has a recommended cold
(parked for more than three hours) tire placard pressure
of 33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn ON the Tire
Pressure Monitoring Telltale Light. Driving the vehicle
may cause the tire pressure to rise to approximately
28 psi (193 kPa), but 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 tire 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. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have
your sensor function checked.

CAUTION!(Continued)
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or 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 using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
558 STARTING AND OPERATING

Premium 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 regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System Messages,
which display in the Driver Information Display
(DID), and a graphic displaying tire pressures
• Tire Pressure Monitoring Telltale Light

STARTING AND OPERATING 559

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, the graphic dis-
play of the pressure value(s) will return to its original
color and the Tire Pressure Monitoring Telltale Light will
extinguish once the updated tire pressure(s) 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.
Service TPM System Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The DID will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“ in place of the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, the
SERVICE TPM SYSTEM
message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
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 housings.
