TIRE PRESSURE MONITORING SYSTEM (TPMS) -
PREMIUM SYSTEM Ð IF EQUIPPED
Tire Pressure Monitoring System (TPMS)
Operation
This system uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module. The wheel sensors monitor tire pressure and
status for all four active road tires.
The TPMS consists of the following components:
²Receiver Module
²Wheel Sensors (attached to each wheel through the
valve stem mounting hole)
²Wheel Sensor 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)
²Yellow Tire Pressure Monitoring Telltale Light
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings 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. Aftermarket 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 Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light is located in
the instrument cluster. The light will illuminate and an
audible chime will sound when one or more of the tires
on your vehicle are significantly under-inflated. The
audible chime will sound once every ignition cycle for
each condition that it detects.
206 STARTING AND OPERATING

When the appropriate conditions exist, the Electronic
Vehicle Information Center (EVIC) displays the following
messages:
NOTE:Your system can be set to display pressure units
in PSI, kPA or BAR.
Should this occur, you should stop as soon as possible,
check the inflation pressure of each tire on your vehicle,
and inflate each tire to the pressure recommended by the
vehicle manufacturer. Once the proper tire pressure is set,the TPMS warning will reset automatically after driving
the vehicle for at least 2 minutes at or above 15 mph (24
km/h).
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
²
The TPMS monitors the four active road tires on the
vehicle, and can inform the driver of a low tire
pressure condition, including low temperature effects.
²It is particularly important that you check the inflation
pressure of each tire on your vehicle, including the
spare (if provided), monthly when the tires are cold.
Inflate each tire to the pressure recommended by the
vehicle manufacturer. Tire inflation pressure informa-
tion is found on the vehicle placard or tire inflation
pressure label.

²The TPMS does not monitor the temporary spare tire.
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 intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition. 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.
Check TPM System Message
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.The EVIC will display the ªCHECK TPM SYSTEMº
message for 3 seconds. In addition, a graphic will be
displayed indicating which of the Tire Pressure Monitor-
ing Sensor(s) is not being received.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the9CHECK TPM SYS-
TEM9text message will no longer display.

WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose or improperly installed, a ªGASCAPº
message will be displayed in the Odometer/Trip Odom-
eter in the instrument cluster. Refer to ªInstrument
Cluster Descriptionº in Section 4 of this manual. Tighten
the fuel filler cap properly and press the odometer/trip
odometer reset button to turn the message off. If the
problem continues, the message will appear the next time
the vehicle is started. Refer to ªOnboard Diagnostic
System Ð OBDIIº in Section 7 of this manual for more
information.
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.
WARNING!
²Never add fuel when the engine is running.
²Never have any smoking materials lit in or near
the vehicle when the fuel cap is removed or the
tank filled.

ONBOARD DIAGNOSTIC SYSTEM Ð OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the ªMalfunction Indicator Light.º It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
²Prolonged driving with the ªMalfunction Indica-
tor Lightº on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
²If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose or improperly
installed. A GASCAP message will be displayed in the
instrument cluster. Tighten the gas cap until a9clicking9
sound is heard. This is an indication that the gas cap is
properly tightened. Press the odometer reset button to
turn the message off. If the problem persists, the message
will appear the next time the vehicle is started. This

If none of these apply to you, then change your engine
oil at every interval shown on schedule ªAº in the
maintenance schedule section of this manual.
NOTE:
Under no circumstances should oil change
intervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
Engine Oil Selection - Non ACEA Categories
For best performance and maxi-
mum protection under all types of
operating conditions, the manu-
facturer only recommends engine
oils that are API certified and
meet the requirements of
DaimlerChrysler Material Stan-
dard MS-6395. Use Mopar or an
equivalent oil meeting the specifi-
cation MS-6395. These Certified Oils exhibit the Ameri-
can Petroleum Institute (API) Engine Oil Certification
Symbol on the front of the oil container. This symbol
means that the oil has been tested, certified and licensed
by the American Petroleum Institute (API) to meet the oil
standards required by the manufacturers.
Engine Oil Selection - ACEA Categories
For countries that use the ACEA European Oil Categories
for Service Fill Oils, use engine oils that meet the require-
ments of ACEA A1/B1, A3/B4 or A3/B3.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap also states the recommended engine oil vis-
cosity grade for your engine.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are certified by
the American Petroleum Institute (API) to display the
symbol on the front of the container or the proper ACEA
category and show the recommended SAE viscosity
grade. Follow the maintenance schedule that describes
your driving type.
