four wheel drive CHRYSLER PT CRUISER 2008 1.G Owners Manual

may be possible based on collision severity and occu-
pant size. The steering wheel hub trim cover and the
upper right side of the instrument panel separate and
fold out of the way as the bags inflate to their full size.
The bags fully inflate in about 50 - 70 milliseconds.
This is about half of the time it takes to blink your eyes.
The bags then quickly deflate while helping to restrain
the driver and front passenger. The driver’s front
airbag gas is vented through vent holes in the sides of
the airbag. The passenger’s front airbag gas is vented
through vent holes in the sides of the airbag. In this
way the airbags do not interfere with your control of
the vehicle.
•
TheOccupant Classification Module (OCM) is lo-
cated beneath the front passenger seat. The OCM
classifies the occupant into categories based on the
measurements made by the seat weight sensors. The
OCM communicates with the Occupant Restraint Con-
troller (ORC). The ORC uses the occupant category to determine whether the front passenger airbag should
be turned off. It also determines the rate of airbag
inflation during a collision.
•
Your vehicle has four
Weight Sensorslocated between
the seat and the floor pan. The weight sensors measure
applied weight and transfers that information to the
OCM.
•
The Side Impact (SRS) Seat Mounted Side Airbags
(If equipped) are designed to activate only in certain
side collisions.
The ORC module determines if a side collision is
severe enough to require the side airbags to inflate.
The side airbag control module will not detect roll
over, front or rear collisions.
64 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Tire Pressures for High Speed OperationThe manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Don’t drive a vehicle loaded to the
maximum capacity at continuous speeds above 75
mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or six, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
324 STARTING AND OPERATING

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 TPM Light.
•
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
BASE SYSTEM — IF EQUIPPEDThe 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:•
Receiver Module
•
Four Tire Pressure Monitoring Sensors
•
Tire 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 WarningThe 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 system fault 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.

WARNING!
•
Improper towing can lead to an injury accident.
•
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have an accident.
•
When hauling cargo or towing a trailer, do not over-
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to brakes,
axle, engine, transmission, steering, suspension, chas-
sis structure or tires.
•
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross the
chains under the trailer tongue and allow enough
slack for turning corners.
•
Vehicles with trailers should not be parked on a grade.
When parking, apply the parking brake on the tow
vehicle. Put the tow vehicle automatic transmission in
PARK. Always, block orchockthe trailer wheels.
•
GCWR must not be exceeded.
•
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
