turn on in the event of an EBD failure. Immediate repair
of the ABS system is required in the event of an EBD
failure.
The operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should turn on for approxi-
mately two seconds and then turn off. The light will
remain on if the parking brake is applied or if a brake
fault is detected. If the parking brake is not applied and
the light remains on, or if the light does not turn on, have
the light inspected by an authorized dealer.
NOTE:The light will turn on when the ignition switch
in the ON position and the parking brake is applied. This
light shows only that the parking brake is applied. It does
not show the degree of brake application. (See page 219
for more information.)
21. Vehicle Security Alarm (VSA) Indicator Light Ð
If Equipped
The VSA indicator Light flashes rapidly when the VSA is
arming, and slowly when the VSA is armed. (See page 15
for more information.)
22. Tire Pressure Monitoring Telltale Light Ð If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires are significantly under-inflated. Ac-
cordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to over-
heat 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.

Please note that the TPMS is not a substitute for proper
tire maintenance, 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 TPMS
low tire pressure telltale.
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more tire pressures is low. The
Tire Pressure Monitoring Telltale Light will flash on and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
condition is removed and reset. (See page 246 for more
information.)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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. After-market 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.

Tire Rotation Ð All Season Tires
The suggested rotation method for vehicles equipped
with all season tires is the ªforward-crossº as shown in
the following diagram.
TIRE PRESSURE MONITOR SYSTEM (TPMS) Ð IF
EQUIPPED
²
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
²The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12ÉF (6.5ÉC). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least 3 hours, or driven less than 1 mile (1 km)
after a 3 hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure
molded into the tire sidewall. Refer to the ªTires ±
General Informationº in this section 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.
246 STARTING AND OPERATING

²The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low-
pressure warning limit for any reason, including low
temperature effects.
²The TPM System 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
the recommended cold placard pressure. Once the low
tire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire
pressure to the recommended cold placard pressure in
order for the Tire Pressure Monitoring Telltale Light to
turn off. The system will automatically update and the
Tire Pressure Monitoring Telltale Light will turn off
once the system receives the updated tire pressures.
The vehicle may need to be driven for up to 10 minutes
above 15 mph (25 km/h) in order for the TPMS to
receive this information.
þFor example, your vehicle may have a recom-
mended cold (parked for more than 3 hours) placard
pressure of 30 psi (207 kPa). If the ambient tempera-
ture is 68ÉF (20ÉC) and the measured tire pressure is
27 psi (186 kPa), a temperature drop to 20ÉF (-7ÉC)
will decrease the tire pressure to approximately 23
psi (157 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 27 psi (186 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 are inflated to the vehicle's recommended
cold placard pressure value.
NOTE:Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual tire
pressure in the tire.

CAUTION!
²The 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
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. After-market 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.
²After 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
Monitoring Sensor.
NOTE:
²
The 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, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale light.
248 STARTING AND OPERATING

Base System Ð 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 the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an audible
chime will sound when tire pressure is low in one
or more of the four active road tires. The audible chime
will sound once every ignition cycle for each condition
that it detects. Should this occur, you should stop as soonas 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 pressures, the system will
automatically update and the Tire Pressure Monitoring
Telltale Light will turn off. The vehicle may need to be
driven for up to 10 minutes above 15 mph (25 km/h) in
order for the TPMS to receive this information. Low
pressure in the spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.
NOTE:The compact spare tire (if so equipped) does not
have a tire pressure monitoring sensor. Therefore, the
TPMS will not monitor the pressure in the compact spare
tire. However, if you install the compact spare tire in
place of a road tire that has a pressure below the
low-pressure warning limit, the Tire Pressure Monitoring
Telltale Light will remain ON and a chime will still sound
each ignition key cycle. 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 Tire Pressure Monitoring Telltale Light will turn
OFF, as long 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 (25 km/h) in order for the TPMS to receive this
information.
Check TPMS Warning
The Tire Pressure Monitoring Telltale Light will flash on
and off for 60 seconds and an audible chime will sound
when a system fault is detected. The flash cycle will
repeat every ten minutes, without an audible chime, until
the fault condition no longer exists. If the ignition key is
cycled, this sequence will repeat, providing the system
fault still exists.
Premium System Ð 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 the tires on your vehicle regularly
and to maintain the proper pressure.The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²3 Trigger Modules (mounted in three of the four
wheel-wells)
²Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
²Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster and an audible
chime will sound when tire pressure is low in one
or more of the four active road tires. The audible chime
will sound once every ignition cycle for each condition
that it detects. In addition, the Electronic Vehicle Infor-
mation Center (EVIC) will display one or more Low
Pressure messages (Left Front, Left Rear, Right Front,
Right Rear) for 3 seconds and a graphic showing the
pressure values of each tire with the low tire pressure
