2008 CHRYSLER PT CRUISER Owners Manual

WARNING!
²Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and wheel
sizes with load ratings approved for your vehicle.
²Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have an accident.
²Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer
readings.
Alignment and Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your
authorized dealer for proper diagnosis.
STARTING AND OPERATING 329

Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE CHAINS
Due to limited clearance, tire chains are not recom-
mended.
CAUTION!
Damage to the vehicle may result if tire chains are
used.
SNOW TIRES
Some areas of the country require the use of snow tires
during Winter. Standard tires are of the all-season type
and satisfy this requirement as indicated by the M+S
designation on the tire sidewall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of four; failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and should
not be operated at sustained speeds over 75 mph (120
km/h).
330 STARTING AND OPERATING

TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, driving,
and braking functions. For these reasons, they wear at
unequal rates and tend to develop irregular wear pat-
terns.
These effects can be reduced by timely rotation of the
tires. The benefits of rotation are especially worthwhile
with aggressive tread designs such as those on all-season
type tires. Rotation will increase tread life, help to main-
tain mud, snow, and wet traction levels and contribute to
a smooth, quiet ride.Follow the recommended tire rotation frequency for your
type of driving found in the ªMaintenance Schedulesº
Section of this manual. More frequent rotation is permis-
sible, if desired. The reason(s) for any rapid or unusual
wear should be corrected before rotating. The suggested
rotation method is the ªforward-crossº shown in the
diagram below.

TIRE PRESSURE MONITOR SYSTEM (TPMS) Ð IF
EQUIPPED
²
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
²The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12ÉF (7ÉC). This means that
when the outside temperature decreases, the tire pres-
sure 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 mi (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
ªTires ± General Informationº in this section for
information on how to properly inflate the vehicle'stires.The tire pressure will also increase as the vehicle
is driven - this is normal and there should be no
adjustment for this increased pressure.
²TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning
limit for any reason, including low temperature effects
and natural pressure loss through the tire.
²TPMS will continue to warn the driver 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 TPM Light to turn off.
The system will automatically update and the TPM
Light will turn off once the system receives the up-
dated tire pressures. The vehicle may need to be
332 STARTING AND OPERATING

driven for up to 10 minutes above 15 mph (25 km/h)
in order for the TPMS to receive this information.
þFor example, your vehicle may have a recom-
mended cold (parked for more than three hours)
placard pressure of 33 psi (227 kPa). If the ambient
temperature is 68É F (20É C) and the measured tire
pressure is 28 psi (193 kPa), a temperature drop to
20É F (-7É C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is
sufficiently low enough to turn ON the TPM Light.
Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPM
Light will still be ON. In this situation, the TPM
Light will turn OFF only after the tires are inflated to
the vehicle's recommended cold placard pressure
value.
CAUTION!
²The 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
operation or sensor damage may result when us-
ing replacement 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.
²After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
STARTING AND OPERATING 333

NOTE:
²TPMS is not intended to replace normal tire care and
maintenance, or to provide warning of a tire failure or
condition.
²TPMS 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.
²TPMS 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 TPM Light.
²Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
BASE SYSTEM Ð IF EQUIPPED
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. 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 check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²Four Tire Pressure Monitoring Sensors
²Tire Pressure Monitoring Telltale Light
334 STARTING AND OPERATING

Tire Pressure Monitoring Low Pressure Warnings
The TPM 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 TPM Light will turn off. The vehicle may
need to be driven for up to 10 minutes above 15 mph (25
km/h) in order for the TPMS to receive this information.
Check TPMS Warning
The TPM Light will flash on and off for 75 seconds 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, providing the systemfault still exists. The TPM 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 as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials which 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 TPM sensors.
NOTE:
1. The compact spare tire (if so equipped) does not have
a tire pressure monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the compact spare tire.

2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will turn ON due to the
low tire.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPM Telltale Light will flash on and
off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPM Telltale
Light will turn OFF, as long no tire pressure is below the
low-pressure warning limit in any of the four active roadtires. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
