Electronic Stability Program (ESP)
The Electronic Stability Program (ESP) enhances direc-
tional control and stability of the vehicle under various
driving conditions. ESP corrects for over/under steering
of the vehicle by applying the brake of the appropriate
wheel to assist in counteracting 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.
•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.ESP On
This mode is the normal operating mode for ESP on
two-wheel drive vehicles. Whenever the vehicle is
started, the ESP system will be in this mode. This mode
should be used for most driving situations. ESP should
only be turned off for specific reasons as noted below.
ESP Partial Off
This mode is entered by momentarily pressing the “ESP
OFF” switch (located in the center switch bank, next to
the hazard flasher switch).
When in the “Partial Off” mode, the TCS
portion of ESP, except for the “limited slip”
feature described in the TCS section, has been
disabled and the “ESP/TCS Indicator Light”
will be illuminated. When in the “Partial Off” mode, ESP
will operate without engine torque management. This
mode is intended to be used if the vehicle is in deep
snow, sand or gravel conditions and more wheel spin
350 STARTING AND OPERATING

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 tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire placard pressure
in order for the “TPMS Warning Lamp” to be turned off.
The system will automatically update and the “TPMS
Warning Lamp” 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 (25 km/h) to
receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire 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 sufficiently low enough to turn on the “TPMSWarning Light.” Driving the vehicle may cause the tire
pressure to rise to approximately 30 psi (207 kPa), but the
“TPMS Warning Light” will still be on. In this situation,
the “TPMS Warning 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 have
been established for the tire size equipped on your
vehicle. Undesirable system operation 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 dam-
age. Do not use aftermarket sealants or balance
beads if your vehicle is equipped with a TPMS, as
damage to the sensors may result.

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 TPMS 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 pressure
gage, even if under-inflation has not reached the level
to trigger illumination of the “TPMS Warning Lamp.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. 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.
372 STARTING AND OPERATING

The Basic TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•TPMS Telltale Warning Light
Tire Pressure Monitoring Low Tire Pressure
Warnings
The “TPMS Telltale Warning Light” will illu-
minate in the instrument cluster, and an au-
dible 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
tire pressure value (located on the placard on the
driver’s-side B-Pillar). The system will automatically
update and the “TPMS Warning Lamp” will extinguish
once the updated tire pressures have been received. NOTE:
The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) to receive this
information.
The “TPMS Warning Lamp” 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. If the
ignition switch is cycled, this sequence will repeat, pro-
viding the system fault still exists. The “TPMS Warning
Lamp” will turn off when the fault condition no longer
exists. A system fault can occur with any of the following
scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.

STARTING AND OPERATING 373

3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles with Compact Spare
1. The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the “TPMS Telltale Warning Light” will turn
on.
3. After driving for up to 20 minutes above 15 mph
(25 km/h), the “TPMS Telltale Warning Light” will flash
on and off for 75 seconds and then remain on solid.4. For each subsequent ignition switch cycle, a chime will
sound, the “TPMS Telltale Warning 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
tire, the TPMS will automatically update, and the “TPMS
Telltale Warning 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 (25 km/h) for
the TPMS to receive this information.
Premium System – If Equipped
The TPMS uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pressure lev-
els. Sensors mounted to each wheel as part of the valve
stem transmit tire pressure readings to the Receiver
Module.
374 STARTING AND OPERATING

NOTE:It is particularly important to regularly check
and maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following compo-
nents:
•Receiver Module
•Four TPMS Sensors
•Three Trigger Modules (mounted in three of the four
wheel wells)
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and graph-
ics displaying tire pressures
•Yellow TPMS Telltale Warning Light
TPMS Low Pressure Warnings
The “TPMS Telltale Warning Light” will illuminate in the
instrument cluster, and an audible chime will be acti-
vated when one or more of the four active road tire pressures are low. In addition, the EVIC will display a
Low Pressure message for three seconds and a graphic
display of the pressure value(s) with the low tire(s)
flashing.Low Tire Pressure Display

STARTING AND OPERATING 375

Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value. The system will automatically update, the graphic
display of the pressure value(s) will stop flashing, and
the “TPMS Telltale Warning 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 (25 km/h) to receive this information.
Check TPMS Message
The “TPMS Telltale Warning 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
EVIC will display aCHECK TPM SYSTEM message for
three seconds. This text message is then followed by a
graphic display, with --in place of the pressure value(s)
indicating which TPMS 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 “TPMS Telltale Warning Light” will
no longer flash, the
CHECK TPM SYSTEM text messageCheck TPM System Display

will not be present, and a pressure value will be dis-
played instead of dashes. 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 TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
Vehicles with Compact Spare
1. The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the pressure
in the compact spare tire.2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, the “TPMS
Telltale Warning Light” will remain on, a chime will
sound, and the EVIC will still display a flashing pressure
value in the graphic display.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the “TPMS Telltale Warning Light”
will flash on and off for 75 seconds and then remain on
solid. In addition, the EVIC will display a CHECK TPM
SYSTEM message for three seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition switch cycle, a chime will
sound, the “TPMS Telltale Warning Light” will flash on
and off for 75 seconds and then remain on solid, and the
EVIC will display a CHECK TPM SYSTEM message for
three seconds and then display dashes (- -) in place of the
pressure value.
