SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each
wheel (Fig. 19). Each sensor has an internal battery
that lasts up to 10 years. The battery is not service-
able. At the time of battery failure, the sensor must
be replaced. The serviceable components of the tire
pressure sensor are:
²Sensor-To-Wheel Grommet
²Valve Stem Cap
²Valve Stem Core
Valve stem caps and cores are specifically designed
for the tire pressure monitoring sensors. Although
similar to standard valve stem caps and cores, they
are different.
CAUTION: Do not use a standard valve stem cap or
core in a tire pressure sensor. Always use the orig-
inal equipment style sensor cap and core.
CAUTION: Do not reuse the Sensor-To Wheel Grom-
met. Always use a new grommet when installing a
pressure sensor and properly torque the sensor
nut.
CAUTION: Do not try to install a tire pressure sen-
sor in a steel wheel or aftermarket wheel. Use only
in original style factory wheels.
OPERATION
Tire pressure sensors are battery operated. They
transmit tire pressure data once every minute at
speeds above 20 mph (32 km/h) or up to once every
hour when stationary (parked). For additional infor-
mation, refer to Appropriate Diagnostic Information.
CAUTION
CAUTION: The use of tire sealants is strictly prohib-
ited for vehicles equipped with the Tire Pressure
Monitoring system. Tire sealants can clog tire pres-
sure sensors.
CAUTION: Tire pressure sensor valve stem caps
and cores are specially designed for the sensors.
Due to risk of corrosion, do not use a standard
valve stem cap or core in a tire pressure sensor in
place of the original equipment style sensor cap
and core.
CAUTION: Do not attempt to install a tire pressure
sensor in a steel wheel or aftermarket wheel. Use
tire pressure sensors in original style factory
wheels only.
NOTE: TPM thresholds have been established for
the original tire size equipped on the vehicle. Use
original size tires only to maintain system accuracy.
DIAGNOSIS AND TESTING - TIRE PRESSURE
SENSOR
NOTE: Tire pressure may increase from 2 to 6 psi
(14 to 41 kPa) during normal driving conditions. Do
NOT reduce this normal pressure build up.
If a fault in the system is detected, always check
air pressure in the tires first with a known accurate
air gauge and correct the inflation pressure. If any
tire is low, inspectalltires.
If gauge-read pressure in the tires does not reflect
the reading on the EVIC, retrain the sensors, then
reevaluate (Refer to 22 - TIRES/WHEELS/TIRE
PRESSURE MONITORING/SENSOR - STANDARD
PROCEDURE). Refer to the appropriate diagnostic
information for complete diagnosis of the Tire Pres-
sure Monitoring System.

TIRES
DESCRIPTION
DESCRIPTION - TIRE
Tires are designed and engineered for each specific
vehicle. They provide the best overall performance
for normal operation. The ride and handling charac-
teristics match the vehicle's requirements. With
proper care they will give excellent reliability, trac-
tion, skid resistance, and tread life.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain, in most
cases, much greater mileage than severe use or care-
less drivers. A few of the driving habits which will
shorten the life of any tire are:
²Rapid acceleration
²Severe application of brakes
²High-speed driving
²Taking turns at excessive speeds
²Striking curbs and other obstacles
²Operating vehicle with over or under inflated
tire pressures
Radial ply tires are more prone to irregular tread
wear. It is important to follow the tire rotation inter-
val shown in the section on Tire Rotation. This will
help to achieve a greater tread-life potential.
TIRE IDENTIFICATION
Tire type, size, load index and speed rating are
encoded in the letters and numbers imprinted on the
side wall of the tire. Refer to the Tire Identification
chart to decipher the code. For example purposes, the
tire size P225/60 R 16 97 T is used in the chart. An
All Season type tire will also have eitherM+S,M&
SorM-S(indicating mud and snow traction)
imprinted on the side wall. An Extra or Light Load
marking ªXLº or ªLLº may also be listed on the side-
wall. The absence of an ªXLº or ªLLº marking infers
a standard load tire.

TIRE CHAINS
Refer to the owners manual supplied with the vehi-
cle to determine whether the use of tire chains is per-
mitted on this vehicle.
DESCRIPTION - RADIAL-PLY TIRES
Radial-ply tires improve handling, tread life, ride
quality and decrease rolling resistance.
Radial-ply tires must always be used in sets of four
and under no circumstances should they be used on
the front only. It is recommended that tires from dif-
ferent manufacturers NOT be mixed. They may be
mixed with a temporary spare tire when necessary. A
maximum speed of 80 km/h (50 mph) is recom-
mended while a temporary spare is in use.
Radial-ply tires have the same load-carrying capac-
ity as other types of tires of the same size. They also
use the same recommended inflation pressures.
DESCRIPTION - REPLACEMENT TIRES
WARNING: FAILURE TO EQUIP THE VEHICLE WITH
TIRES HAVING ADEQUATE SPEED CAPABILITY
CAN RESULT IN SUDDEN TIRE FAILURE.It is recommended that tires equivalent to the orig-
inal equipment tires be used when replacement is
needed.
Failure to use equivalent replacement tires may
adversely affect the safety and handling of the vehi-
cle.
The original equipment tires provide a proper com-
bination of many characteristics such as:
²Ride
²Noise
²Handling
²Durability
²Tread life
²Traction
²Rolling resistance
²Speed capability
The use of tires smaller than the minimum tire
size approved for the vehicle can result in tire over-
loading and failure.
Use tires that have the approved load rating for
the vehicle and never overload them. Failure to equip
the vehicle with tires having adequate speed capabil-
ity can result in sudden tire failure and loss of vehi-
cle control.
The use of oversize tires may cause interference
with vehicle components. Under extremes of suspen-
sion and steering travel, interference with vehicle
components may cause tire damage.
DESCRIPTION - SPARE TIRE (TEMPORARY)
The temporary (convenience) spare tire is designed
for emergency use only. The original tire should be
repaired and reinstalled, or replaced with a new, at
the first opportunity.
The temporary (convenience) spare tire should be
inflated to the pressure listed on its sidewall. Do not
exceed speeds of 80 km/h (50 mph) when the tempo-
rary spare tire is in use on the vehicle. Refer to the
Owner's Manual for more details.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - TIRE NOISE

WHEEL COVER
DESCRIPTION
This vehicle uses a bolt-on type wheel cover (Fig.
30).
This bolt-on wheel cover cannot be removed from
the wheel until three of the five wheel mounting nuts
shown are removed (Fig. 30). The bolt-on wheel cover
can then be removed with the remaining two wheel
nuts tightened in place.
REMOVAL
(1) Noting the location of the valve stem in rela-
tionship to the wheel mounting nuts, remove the
three wheel mounting nuts securing the wheel cover
to the wheel and hub (Fig. 30).
CAUTION: When removing the wheel cover, do not
pry the wheel cover from the wheel. This can resultin damage to the wheel cover. The wheel cover is
removed by pulling it off the wheel by hand.
(2) Grasp the wheel cover at the edges in line with
the remaining installed wheel nuts and pull straight
outward from the wheel. This will pop the wheel
cover retaining tabs over the two remaining wheel
nuts, removing the wheel cover from the wheel.
INSTALLATION
NOTE: Wheel mounting nuts must be installed on
the studs as shown to allow installation of the
wheel cover (Fig. 31).

CAUTION: Do not try to install a tire pressure sen-
sor in a steel wheel or aftermarket wheel. Use only
in original style factory wheels.
OPERATION
The tire pressure sensors are battery operated.
Each sensor transmits tire pressure data approxi-
mately once every minute at speeds above 13 mph
(20 km/h). Each sensor's (transmitter) broadcast is
uniquely coded so that the SKREEM can monitor the
states of each individual sensor on the vehicle.
Unlike prior model year TPM systems, a magnet is
not required to retrain the system. The SKREEM
automatically learns while driving after a sensor has
been replaced. (Refer to 22 - TIRES/WHEELS/TIRE
PRESSURE MONITORING/SENSOR - STANDARD
PROCEDURE) For additional information, refer to Appropriate
Diagnostic Information.
CAUTION
CAUTION: The use of tire sealants is strictly prohib-
ited for vehicles equipped with the Tire Pressure
Monitoring system. Tire sealants can clog tire pres-
sure sensors.
CAUTION: Tire pressure sensor valve stem caps
and cores are specially designed for the sensors.
Due to risk of corrosion, do not use a standard
valve stem cap or core in a tire pressure sensor in
place of the original equipment style sensor cap
and core.
CAUTION: Do not attempt to install a tire pressure
sensor in a steel wheel or aftermarket wheel. Use
tire pressure sensors in original style factory
wheels only.
NOTE: TPM thresholds have been established for
the original tire size equipped on the vehicle. Use
original size tires only to maintain system accuracy.
DIAGNOSIS AND TESTING - TIRE PRESSURE
SENSOR
NOTE: Tire pressure may increase from 2 to 6 psi
(14 to 41 kPa) during normal driving conditions. Do
NOT reduce this normal pressure build up.
If a fault in the system is detected, always check
air pressure in the tires first with a known accurate
air gauge and correct the inflation pressure. If any
tire is low, inspect allthe tires. If the gauge-read pressure in the tires does not
indicate a tire pressure issue, refer to the appropri-
ate diagnostic information.
STANDARD PROCEDURE - TIRE PRESSURE
SENSOR RETRAIN
CAUTION: If a sensor is replaced, the vehicle must
be parked for a minimum of 15 minutes for the sys-
tem to be ready to learn the new sensor ID code.
(1) Park the car for a minimum of 15 minutes.
(2) Drive the vehicle for a minimum of five min-
utes while maintaining a continuous speed above 13
mph (20 km/h). During this time the system will
learn the new sensor ID code and will clear any
DTC's automatically.
NOTE: If a sensor cannot be trained, refer to appro-
priate diagnostic information.
REMOVAL
(1) Remove tire and wheel assembly from vehicle.
(Refer to 22 - TIRES/WHEELS - REMOVAL)
CAUTION: The cap used on this valve stem con-
tains an O-ring seal to prevent contamination and
moisture from entering the valve stem. Retain this
valve stem cap for reuse. Do not substitute a regu-
lar valve stem cap in its place.
CAUTION: The valve stem used on this vehicle is
made of aluminum and the core is nickel plated
brass. The original valve stem core must be rein-
stalled and not substituted with a valve stem core
made of a different material. This is required to pre-
vent corrosion in the valve stem caused by the dif-
ferent metals.
(2) Dismount tire from wheel following tire
changer manufacturers instructions while paying
special attention to the following to avoid damaging
the pressure sensor: (a) When breaking the tire bead loose from the
wheel rim, avoid using the Bead Breaker in the
area of the sensor. That includes both front and
rear beads of the tire. (b) When preparing to dismount the tire from
the wheel, carefully insert the mounting/dimount-
ing tool at the valve stem   10É (Fig. 1), then pro-
ceed to dismount the tire from the wheel. Use this
process on both the upper and lower tire beads.
(3) Using a thin wall socket, remove special nut
retaining sensor to wheel (Fig. 2). (4) Remove sensor from wheel (Fig. 2).
