RADIAL FORCE VARIATION
Radial Force Variation can be checked using the
Hunter GSP 9700 Vibration Control System (Wheel
Balancer) or equivalent, if available. This type of
equipment helps to correct ride disturbances by
reducing the radial force variation of an assembly
through re-indexing of the tire to wheel.
The equipment manufacturer or DaimlerChrysler
Corporation may supply reference values as guide-
lines. Radial force measurements above the reference
value may not always result in a ride disturbance,
nor do they automatically mean the assembly compo-
nents are out of specification. Do not replace compo-
nents based on radial force values alone. Balancing,
runout diagnosis, re-indexing, and subjective road
testing must be performed as outlined in previous
sections of this diagnosis and testing procedure.
Use the Radial Force equipment to identify suspect
assemblies and minimize the radial forces. After all
suspect assemblies are optimized, reinstall the
assemblies and road test the vehicle. If a disturbance
still exists and all other vibration diagnostic proce-
dures have been completed, replace one tire or one
wheel at a time, starting with the assembly having
the highest force variation. Be sure to minimize each
new assembly. Road test the vehicle following each
replacement. Continue this process until the distur-
bance is resolved.
NOTE: When using Radial Force equipment, it is
critically important to set proper tire inflation pres-
sure and ensure centering of the wheel on the
equipment spindle.

STANDARD PROCEDURE - TIRE AND WHEEL
BALANCE
NOTE: Balance equipment must be calibrated and
maintained per equipment manufacturer's specifica-
tions.
Wheel balancing can be accomplished with either
on-vehicle or off-vehicle equipment.
NOTE: If using on-vehicle balancing equipment, on
the driving axle, remove the opposite wheel and tire
assembly.
It is recommended that a two-plane dynamic bal-
ancer be used when a wheel and tire assembly
requires balancing. A static balancer should only be
used when a two-plane balancer is not available.
Balance wheel and tire assemblies dynamically and
statically to less than 0.25 (
1¤4) ounce.
For static balancing, find location of heavy spot
causing imbalance. Counter balance wheel directly
opposite the heavy spot. Determine weight required
to counterbalance the area of imbalance. Place half of
this weight on theinnerrim flange and the other
half on theouterrim flange (Fig. 8).
For dynamic balancing, the balance equipment is
designed to indicate the location and amount of
weight to be applied to both the inner and outer rim
flanges (Fig. 9).
The aluminum wheels on this vehicle use a unique
wheel weight (Fig. 10). This wheel weight is designed
to fit the contoured surface of the wheel (Fig. 10).
When balancing an aluminum wheel, this wheel
weight must be used. Do not use any other type of
wheel weight. It will not properly fit the contour of
the wheel.
Always verify the Balance. When using off-vehicle
equipment, rotate assembly 180 degrees on balance
equipment to verify balance. Variation should not be
more than 0.125 (
1¤8) ounce. If variation is more than
0.125 ounce, balancing equipment could be malfunc-
tioning.

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.

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.
