2009 CHRYSLER PT CRUISER TPMS

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and 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 TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

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 opera-
tion or sensor damage may result when using re-
placement 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.
8. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.
Vehicle Warning Messages
When the appropriate conditions exist, “door,” “gate,”
“LoW TirE,” “CHAngE OIL”or “GASCAP” will display
in the odometer.
NOTE:
If the instrument cluster is equipped with the
optional Electronic Vehicle Information Center (EVIC),
then all warnings including ”Low Tire,” “Door Ajar” and
“Liftgate Ajar” will only display in the EVIC. (Refer to
“Electronic Vehicle Information Center (EVIC)” in this
section for specific messages).
LoW TirE
When the appropriate condition exists, the odometer
display will toggle between LoW and TirE for three
cycles.

history information will be erased, and the averaging will
continue from where it was before the reset.
Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to a text display of LOW FUEL. This display will con-
tinue until the vehicle runs out of fuel. Adding a signifi-
cant amount of fuel to the vehicle will turn off the LOW FUEL text and a new DTE value will be displayed, based
on the current values in the DTE calculation and the
current fuel tank level.Elapsed Time
Shows the total elapsed time of travel since the last reset
when the ignition switch is in the ACC position. Elapsed
time will increment when the ignition switch is in the ON
or START position.
Tire Pressure Monitor (TPM)
Refer to Section 5 “Tire Pressure Monitoring System
(TPMS),” for system operation.
Personal Settings (Customer-Programmable
Features)
This allows the driver to set and recall features when the
shift lever is in PARK (automatic transmission) or the
vehicle is stopped (manual transmission).

TIRE PRESSURE MONITORING SYSTEM (TPMS)
The TPMS will warn you of a low tire pressure based on
the vehicle recommended cold placard pressure.The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (7°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three-hour period. The cold tire inflation pressure must
not exceed the maximum inflation pressure molded into
the tire sidewall. Refer to the “Tires – General Informa-
tion” in this section for information on how to properly
inflate the vehicle’s tires. The tire pressure will also
increase as the vehicle is driven - this is normal and there
should be no adjustment for this increased pressure.
TPMS will warn you of a low tire pressure if the tire
pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natu-
ral pressure loss through the tire.
Tire Rotation

STARTING AND OPERATING 265

TPMS will continue to warn you of low tire pressure as
long as the condition exists, and will not turn off until the
tire pressure is at or above the recommended cold
placard pressure. Once the low tire pressure warning has
been illuminated, you must increase the tire pressure to
the recommended cold placard pressure in order for the
Tire Pressure Monitoring Telltale Light to turn off. The
system will automatically update and the TPMS Telltale
Light will turn off once the system receives the updated
tire pressures. The vehicle may need to be driven for up
to 20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn ON the TPMSTelltale Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Telltale Light will still be ON. In this situation, the
TPMS Telltale Light will turn OFF only after the tires are
inflated to the vehicle’s recommended cold placard pres-
sure 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 opera-
tion or sensor damage may result when using re-
placement 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.
266 STARTING AND OPERATING

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 Tire Pressure Monitoring
Sensor.
NOTE:
•TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
•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.
•TPMS is not a substitute for proper tire maintenance,
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 TPMS Telltale Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The TPMS 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.
NOTE: It is particularly important for you to perform a
monthly tire pressure check on, and to maintain the
proper pressure of all the tires on your vehicle.

STARTING AND OPERATING 267

The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS 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. 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 vehicle’s
recommended cold placard pressure value. Once the
system receives the updated tire pressures, the system
will automatically update and the TPMS Telltale Light
will turn off. The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
The TPMS Telltale Light will flash on and off for 75 sec-
onds and then remain on solid when a system fault is
detected. The system fault will also sound a chime. If the
ignition key is cycled, this sequence will repeat, provid-
ing the system fault still exists. The TPMS Telltale Light
will turn off when the fault condition no longer exists. 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 (RF)
as the TPMS sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Excessive 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 TPMS Sensors.
