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 using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
25. Airbag Indicator
The airbag indicator light illuminates and re-
mains lit for six to eight seconds when the
ignition is first turned ON. If the light does not
come on when the ignition is first turned on, orthe light stays on or comes on while driving, have the
airbag system checked by an authorized dealer.
26. 4WD Indicator
The 4WD indicator light illuminates when the transfer
case is in 4WD position.
27. SVC (Service) 4WD Indicator
The SVC 4WD light will illuminate when the ignition key
is turned to the ON position and will stay on for two
seconds. If the light stays on or comes on during driving,
it means that the 4WD system is not functioning properly
and that service is required.

Automatic Temperature Control (ATC) Ð If Equipped
The control can be turned on by pressing the Power knob.
When the control is turned on, it will be in the last mode
prior to being turned off. Pressing the Power knob again
will turn off the control. The control can also be turned on
by pressing any button and it will display the corre-
sponding operation mode for that button.
Automatic Control
The ATC system can maintain a steady comfort level in
various weather conditions with a simple operation:
²Select your desired temperature setting by pressing
the + or - side of the Temp rocker switches. A digital
temperature setting for driver and passenger will be
displayed. The ATC system uses an infrared sensor
located in the overhead console to measure the tem-
perature of the driver and passengers. Based on the
sensor input, the system will automatically control
comfort by varying the temperature, fan speed, and
mode. This maintains a comfortable temperature, even
under changing conditions. It is important that objects
are not blocking the infrared sensor. It is also impor-
tant that objects are not used that may scratch or
damage it in any way.

Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
²Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
²Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESP/TCS Indicator Light
The ESP/TCS Indicator Light starts to flash as
soon as the tires lose traction and the TCS or
ESP system becomes active. It will also flash
once a swaying trailer is detected and the
Trailer Sway Control (TSC) system activates. If the ESP/
TCS 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.
WARNING!
²ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.

NOTE:When the vehicle is in 4WD LOW, a feature of
the ESP system remains active whether the ESP is on or
off. This feature functions similar to a limited slip differ-
ential and controls the wheel spin across an axle. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that
is not spinning.
WARNING!
In the Partial Off mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize a swaying
trailer and will take the appropriate actions to attempt to
stop the sway. The system will reduce engine power andapply individual brakes that will counter act the sway of
the trailer. TSC will become active automatically once the
swaying trailer is recognized. No driver action is re-
quired. TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and follow the
tongue weight recommendations. For additional infor-
mation on towing a trailer with your vehicle, refer to
9Trailer Towing9in Section 5.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ESP/BAS Warning Light
and the yellow ESP/TCS Indicator Light in the instru-
ment cluster both come on when the ignition switch is
turned to the ON position. They should both go out with
the engine running. If the ESP/BAS Warning Light comes
on continuously with the engine running, a malfunction
has been detected in either the ESP or BAS system, or
both. If this light remains on after several ignition cycles,
306 STARTING AND OPERATING

For example, your vehicle has a recommended cold
(parked for more than three hours) placard pressure of 33
psi (227 kPa). If the ambient temperature is 68ÉF (20ÉC)
and the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20ÉF (-7ÉC) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn on the TPMS
light. Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPMS light
will still be ON. In this situation, the TPMS 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 have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use aftermarket tire sealants or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture and dirt from entering the valve stem, which
could damage the tire pressure monitoring sensor.

NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving 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.
²The 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
Lamp.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System ± If Equipped
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 TPMS consists of the following components:
²Receiver module
²Four tire pressure monitoring sensors
²Tire Pressure Monitoring Telltale Lamp
