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.
For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 30 psi (207 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 27 psi (186 kPa), a temperature drop to
20°F (-7°C) will decrease the tire pressure to ap-
proximately 26 psi (179 kPa). This tire pressure is
sufficiently low enough to turn ON the TPM Telltale
Light. Driving the vehicle may cause the tire pres-
sure to rise to approximately 27 psi (186 kPa), but
the TPM Telltale Light will still be ON. In this
situation, the TPM Telltale Light will turn OFF only
after the tires are inflated to the vehicle’s recom-
mended cold placard pressure value.
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
operation or sensor damage may result when us-
ing replacement equipment 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.
•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 TPM 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
gauge, even if under-inflation has not reached the
level to trigger illumination of the TPM Telltale Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
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 check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors,
266 STARTING AND OPERATING
ProCarManuals.com

•CORAX Receiver module,
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
•TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. A spare with a
pressure below the low-pressure limit will not cause the
TPM Telltale Light to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the EVIC will display one or
more low pressure messages (Left Front, Left Rear, Right Front, Right Rear) for three seconds and a graphic
showing the pressure values of each tire with the low tire
pressure values flashing.
STARTING AND OPERATING 267

Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle’s recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the TPM 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 informa-
tion.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display aCHECK TPM SYSTEM message for three seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.
268 STARTING AND OPERATING
ProCarManuals.com

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the TPM Telltale Light will no longer
flash, and theCHECK TPM SYSTEM message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors,
or equipped with the incorrect type of TPM sensors.General Information

NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the Fan control to HI. This allows the heater core to act as
a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the pointer drops back into the normal range 200–
230°F (93–110°C). If the pointer remains at 240°F
(116°C) or greater and you hear a chime, turn the
engine off immediately and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the hood
yourself, refer to Section 7 and follow the warnings
under the Cooling System Pressure Cap paragraph.
TIREFIT TIRE REPAIR
Small punctures, particularly those in the tread, can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).

WARNING!
•Do not attempt to repair a tire on the side of the vehicle close to
traffic. Pull far enough off the road to avoid the danger of being hit
when operating the jack or repairing a tire.
•Cuts or punctures larger than approximately 0.16 in (4 mm), tire
damage caused by driving with extremely low tire pressure or on
a flat tire, or a damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances. Do not drive
the vehicle under such circumstances. Contact your nearest autho-
rized dealer for assistance.
•Take care not to allow the contents of TIREFIT to come in contact
with hair, eyes or clothing. TIREFIT is harmful if inhaled, swal-
lowed, or absorbed through the skin: It causes skin, eye, and
respiratory irritation. Any contact with eyes or skin should be
flushed immediately with plenty of water. If clothing comes in
contact with TIREFIT, change clothing as soon as possible.
•In case of allergic reaction or rash, consult a physician immedi-
ately. Keep TIREFIT out of reach of children. If swallowed, rinse
mouth immediately with plenty of water and drink plenty of
water. Do not induce vomiting! Consult a physician immediately.
•Keep away from open flame or heat source.
