If difficult to balance, break down the wheel and
tire assembly and check for loose debris inside tire.
Prior to disassembly, mark (index) the tire at the
valve stem. Use this mark in order to remount the
tire in its original orientation with respect to the
wheel.
STANDARD PROCEDURE - TIRE AND WHEEL
MATCH MOUNTING
Wheels and tires are match mounted at the factory.
This means that the high spot of the tire is matched
to the low spot on the wheel rim. This technique is
used to reduce runout in the wheel and tire assem-
bly. The high spot on the tire is marked with a paint
mark or a bright colored adhesive label on the out-
board sidewall. The low spot on the wheel is identi-
fied with a label on the outside of the rim and a dot
or line in the drop well area of the rim (inside where
the tire mounts). If the outside label has been
removed, the tire will have to be removed to locate
the dot or line on the inside of the rim. The tire can
then be match mounted to the tire.
Information on match mounting the tire to the
wheel can be found in Tire and Wheel Runout/Match
Mounting, items (2) through (5), within Diagnosis
And Testing - Tire And Wheel Vibration. (Refer to 22
- TIRES/WHEELS - DIAGNOSIS AND TESTING)
STANDARD PROCEDURE - TIRE AND WHEEL
ROTATION
NON-DIRECTIONAL TREAD PATTERN TIRES
Tires on the front and rear axles operate at differ-
ent loads and perform different functions. For these
reasons, they wear at unequal rates, and tend to
develop irregular wear patterns. These effects can bereduced by timely rotation of tires. The benefits of
rotation are especially worthwhile. Rotation will
increase tread life, help to maintain mud, snow, and
wet traction levels, and contribute to a smooth, quiet
ride.
The suggested rotation method is the forward-cross
tire rotation method (Fig. 11). This method takes
advantage of current tire industry practice which
allows rotation of radial-ply tires. Other rotation
methods may be used, but may not have all the ben-
efits of the recommended method.
NOTE: Only the 4 tire rotation method may be used
if the vehicle is equipped with a low mileage or tem-
porary spare tire.
DIRECTIONAL TREAD PATTERN TIRES
Some vehicles are fitted with special high-perfor-
mance tires having a directional tread pattern. These
tires are designed to improve traction on wet pave-
ment. To obtain the full benefits of this design, the
tires must be installed so that they rotate in the cor-
rect direction. This is indicated by arrows on the tire
sidewalls.
When wheels and tires are being installed, extra
care is needed to ensure that this direction of rota-
tion is maintained.
Refer to Owner's Manual for rotation schedule.

TIRE PRESSURE MONITORING
DESCRIPTION
Some versions of this vehicle are equipped with
Tire Pressure Monitoring (TPM). TPM monitors air
pressure in the four road tires. The system alerts the
driver when tire pressure in any of the four road
wheels falls below a predetermined threshold (pres-
sure too low).
Depending on optional equipment, a vehicle may
have four or five sensors (fifth sensor located in spare
wheel). Although a pressure sensor may be present in
the spare tire wheel of the five sensor system, pres-
sure in the spare tire is not monitored.
There are two systems available, Base and Pre-
mium. The Base system offers an indicator lamp,
warning the driver of a pressure issue. An audible
chime also sounds once when a pressure issue occurs.
In addition to these features, the Premium system
offers an Electronic Vehicle Information Center
(EVIC) display of information.
For further information, refer to the Owners Man-
ual or the appropriate diagnostic information.

OPERATION
The Tire Pressure Monitoring (TPM) system uses
radio and sensor technology to monitor tire air pres-
sure levels. Sensors, mounted to each road wheel as
part of the valve stem, transmit a low frequency indi-
cating their individual pressure to a receiver located
in the Wireless Control Module (WCM) portion of the
Sentry Key Remote Electronic Entry Module
(SKREEM). These transmissions occur approximately
once every minute at speeds over 20 mph (32 km/h).
The Tire Pressure Monitoring system remains active
even if no tire pressure related message is displayed.
The sensors lay dormant (Park Mode), then wake
and start transmitting (Drive Mode) when the vehicle
first reaches speeds over 20 mph (32 km/h). Once the
wheels stop rotating for a period of approximately 30
minutes, the sensors shut down until again awaken.
Although not transmitting as when in Drive Mode,
while in Park Mode, the sensors still transmit
approximately once every 13 hours to let the receiver
know air pressure status at that time.
The receiver only receives information from the
four rotating tires. A fifth sensor may be located in
the spare tire wheel, depending on vehicle options.
Although this fifth sensor may be present, it does not
broadcast any information because it does not rotate.
When the system detects that a tire is going low,
below the Low Pressure (lamp) ON Threshold (See
following table), the driver is alerted to the situation.
The Base system illuminates an indicator lamp,
warning the driver of a pressure issue and sounds an
audible chime. In equipped with the Premium sys-
tem, the information is also displayed on the Elec-
tronic Vehicle Information Center (EVIC).
Once pressure in the suspect tire raises above the
Low Pressure (lamp) OFF Threshold, the lamp will
go out and the system returns to normal.
TPM THRESHOLD PRESSURES
DESCRIPTION SPECIFICATION
Placard Pressure (Cold) 36 PSI (248 kPa)
Low Pressure OFF Threshold 33 PSI (228 kPa)
Low Pressure ON Threshold 28 PSI (193 kPa)
SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each road
wheel (Fig. 18), and depending on factory wheel
options, a sensor may be located in the spare tire
wheel. Both aluminum and steel wheels are used in
this system, although sensors for one type wheel can-
not be used in the other type wheel.Each sensor has an internal battery that lasts up
to 10 years. The battery is not serviceable. At the
time of battery failure, the sensor must be replaced.
The serviceable components of the tire pressure sen-
sor 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 attempt to install a tire pressure
sensor in an aftermarket wheel. Use only in original
style factory wheels.
OPERATION
The battery operated tire pressure sensors lay dor-
mant (Park Mode), then wake and start transmitting
(Drive Mode) when the vehicle first reaches speeds
over 20 mph (32 km/h). Once the wheels stop rotat-
ing for a period of approximately 30 minutes, the
sensors shut down until again awaken. Although not
transmitting as when in Drive Mode, while in Park
Mode, the sensors still transmit approximately once
every 13 hours to let the receiver know air pressure
status at that time.
Each sensor transmits tire pressure data approxi-
mately once every minute. Each sensor's (transmit-
ter) broadcast is uniquely coded so that the wireless
control module (WCM) can monitor the state of each
of the sensors on the four rotating road wheels. The
WCM (located in the SKREEM) automatically learns
and stores the sensor's ID while driving after a sen-
sor has been replaced. There is no retraining neces-
sary.
The receiver only receives information from the
four rotating tires. A fifth sensor may be located in
the spare tire wheel, depending on vehicle options.
Although this fifth sensor may be present, it does not
broadcast any information because it does not rotate.
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, inspectallthe tires.
If the gauge-read pressure in the tires does not
indicate a tire pressure issue, refer to the appropri-
ate 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. 17), 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. 18).
(4) Remove sensor from wheel (Fig. 18).
INSTALLATION
NOTE: Before reinstalling a tire pressure sensor,
replace sealing grommet at base of valve stem.
(1) Wipe area clean where sensor sealing grommet
contacts wheel. Make sure surface of wheel is not
damaged.
(2) Install sensor in wheel as shown (Fig. 18). Do
not attempt to mount sensor otherwise, damage may
occur.
(3) Using a thin wall socket, install special sensor
nut (Fig. 18). Tighten nut to 4 N´m (35 in. lbs.)
torque.

CAUTION: Over-torquing the sensor nut by as little
as 12 N´m (106 in. lbs.) may result in sensor sepa-
ration from the valve stem. Under this condition,
the sensor may still function, however, the condi-
tion should be corrected immediately.
(4) Mount tire on wheel following tire changer
manufacturers instructions, paying special attention
to the following to avoid damaging tire pressure sen-
sor:
(a) Rotating Wheel Tire Changers - Once the
wheel is mounted to the changer, position the sen-
sor valve stem approximately 210É from the head
of the changer in a clockwise direction before rotat-
ing the wheel (also in a clockwise direction) to
mount the tire (Fig. 19). Use this procedure on
both the upper and lower tire beads.
(b) Rotating Tool Tire Changers - Position the
wheel on the changer so that the sensor valve stem
is approximately 210É from the head of the changer
in a clockwise direction from the mounting end of
the tool (Fig. 20) Make sure the sensor is clear of
the lower bead breaker area to avoid damaging the
sensor when the breaker rises (Fig. 20). Rotate the
tool in a counterclockwise direction to mount the
tire. Use this procedure on both the upper and
lower tire beads.
(5) Install wheel and tire assembly on vehicle.

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.
