Tire Pressure Monitor System
The Tire Pressure Monitor System (TPM) monitors
the pressure in all tires. The TPM system uses
wireless technology to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the valve stem,
transmit tire pressure readings to a computer which
monitors for low pressure. If low pressure is measured,
the TPM Indicator Light will illuminate.
The TPM system informs you of a low tire pressure
condition. If this occurs, correct your tire inflation pres-
sure as soon as possible, and inspect all of your tires. Be
sure to use a high quality gauge when adjusting pressure.
The TPM system is designed to periodically monitor your
tire pressure but cannot be expected to function as a tire
pressure gauge. There can be a delay between the instant
you adjust the air pressure in a tire and when the system
updates the display. The TPM system is not intended to
provide you with notification of rapid air loss.
The TPM system will cause the indicator lamp in the
instrument cluster to illuminate whenever the pressure in
one tire falls 25% below the recommended pressure
shown on the tire label.
NOTE:A TPM system does not replace normal tire
maintenance.
CAUTION!
The TPM system has been optimized for the original
equipment tires and wheels. TPM system pressures
have been established for the tire size equipped on
your vehicle. Undesirable operation or sensor dam-
age 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 aftermarket tire sealant or balance beads as
damage to the sensors may result. The standard
TIREFIT system (see Tirefit Tire Repair and Jacking
Instructions in the What To Do In Emergencies
section) is specifically designed to operate in con-
junction with the TPM system, and will not damage
the sensors.

NOTE:The pressure in your tires changes with tem-
perature. A significant decrease in temperature could
reduce cold inflation pressure below the TPM setpoint.
For example, tires inflated to the proper cold inflation
pressure on a warm day or in a warm garage could
illuminate the TPM indicator lamp on the following day
if the temperature is very cold.ALWAYScheck the
pressure in your tires if the TPM lamp is illuminated.
Tire Chains
The RUD-maticDISC is the only tire chain system
approved for use on the Chrysler Crossfire.
Chains should only be used on the rear wheels and only
with the recommended winter mud and snow (M+S)
tires and wheels. Follow the manufacturer’s mounting
instructions.
Tire chains should only be driven on snow-covered roads
at speeds not to exceed 30 mph (48 km/h). Remove
chains as soon as possible when driving on roads without
snow.
When driving with tire chains, press the ESP control
switch to OFF.
CAUTION!
Damage to the vehicle may result if unapproved tire
chains are used.
Original Equipment Tires
Your vehicle is equipped with either sport performance
tires or all-season performance tires. The sport perfor-
mance tires offer the maximum road handling capability
in dry and wet weather conditions. The all-season per-
formance tires, while offering slightly less road handling
capability, are able to provide traction capability in snow
and ice conditions. Both types of tires are rated for high
speed operation. It is important that you know what type
of tires your vehicle is equipped with so that you
understand their traction and handling characteristics for
various road conditions. Replacement tires should be of
the same size and speed rating to continue to provide the
same level of performance you are accustomed to.
158 STARTING AND OPERATING

Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves and will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the indicators appear
in two or more adjacent grooves, the tire should be
replaced.Many states have laws requiring tire replacement at this
point.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion placard for the size designation of your tire. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.
160 STARTING AND OPERATING

WARNING!
Cuts or punctures larger than approximately 0.16 in.
(4 mm), tire damage caused by driving with ex-
tremely low tire pressure or on a flat tire, or a
damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances.
Do not drive the vehicle under such circumstances.
Contact your nearest authorized dealer for assistance.
Take care not to allow the contents of TIREFIT to
come in contact with hair, eyes or clothing. TIREFIT
is harmful if inhaled, swallowed or absorbed
through the skin: It causes skin, eye and respiratory
irritation. Any contact with eyes or skin should be
flushed immediately with plenty of water. If cloth-
ing comes in contact with TIREFIT, change clothing
as soon as possible.
In case of allergic reaction or rash, consult a physician
immediately. Keep TIREFIT out of reach of children.
If swallowed, rinse mouth immediately with plenty
of water and drink plenty of water. Do not induce
vomiting! Consult a physician immediately.
Keep away from open flame or heat source.
Sealing tire with TIREFIT
1. Set the parking brake and turn on the hazard warning
flashers.
2. Move the transmission selector lever to the PARK
position (manual transmission to FIRST or REVERSE
gear) and turn off the engine.
3. Remove the TIREFIT kit and electric air pump from
the area below the cargo compartment carpet.
4. Open flap (2) on the electric air pump.
5. Pull the power plug (4) and air hose (5) along with the
pressure gauge out of the air pump housing.
6. Screw the air hose (5) onto the hose connection on the
TIREFIT sealant bottle (1).
7. Holding the sealant bottle by the top, insert it down-
wards into the recess (3) on the air pump.
8. Unscrew the valve cap from the valve on the deflated
tire.
9. Screw the filler hose from the sealant bottle on the tire
valve.

10. Insert the power plug (4) into the power point on the
instrument panel.
11. Turn the ignition key to the ON/RUN position.
12. Press the switch on the air pump to 1. The air pump
should start to inflate the tire.
13. After five minutes, the tire should be inflated to at
least 26 psi (180 kPa) on the pressure gauge.
14. If the tire doesn’t inflate to this level, press the air
pump switch to 0, disconnect the TIREFIT system from
the tire, and drive the vehicle back and forth approxi-
mately 30 feet (9.1 m) to distribute the sealant more
evenly within the tire.
15. Attach the air pump hose directly to the tire, press the
switch to 1, and inflate the tire again.NOTE:If a tire
pressure of 26 psi (180 kPa) is not reached after five
minutes, the tire is too badly damaged. Do not attempt to
drive the vehicle further, and call for assistance.16. If a tire pressure of 26 psi (180 kPa) is obtained, press
the air pump switch to 0, turn the ignition switch to the
OFF/LOCK position, and disconnect the TIREFIT sys-
tem.
17. Drive the vehicle for about 10 minutes to ensure
optimum distribution of the tire sealant within the tire.
18. Check the pressure in the tire. If the pressure is above
19 psi (130 kPa), inflate the tire to the pressure indicated
on the tire pressure label on the driver side latch pillar.
19. Have the tire inspected at the earliest opportunity at
an authorized dealer or tire service center.
NOTE:Do not exceed 50 mph (80 km/h) until the tire
has been inspected.
NOTE:If a pressure of at least 19 psi (130 kPa) cannot
be maintained in the tire, the tire is too badly damaged.
Do not attempt to drive the vehicle further, and call for
assistance.
176 WHAT TO DO IN EMERGENCIES

•Turn on the hazard warning flashers and park the
vehicle on a firm, level surface; avoid ice or slippery
areas.
•Firmly set the parking brake and shift the transmission
selector lever into PARK (manual transmission to
FIRST or REVERSE gear).
•Turn off the engine.
•Block the wheel diagonally opposite the flat tire.
•Passengers must not remain in the vehicle when the
vehicle is jacked.
NOTE:The jack is designed exclusively for jacking up
the vehicle at the specified jack location points built
beneath either side of the vehicle.
Jack Location and Instructions
1. Remove the jack and jack handle from stowage be-
neath the cargo compartment carpet.
178 WHAT TO DO IN EMERGENCIES

Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when roads are
slushy.
2. Slow down if the road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain enough distance between your vehicle and
the vehicle in front to avoid a collision in a sudden stop.
FREEING A STUCK VEHICLE
In order to free a stuck vehicle you must turn off the
Electronic Stability Program (ESP) before attempting to
“rock” the vehicle.
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverse
and Drive. Usually the least accelerator pedal pressure to
maintain the rocking motion without spinning the
wheels is most effective.
NOTE:ESP should be turned on again after freeing the
vehicle from a stuck condition.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
184 WHAT TO DO IN EMERGENCIES

Check the battery every four to six weeks to ensure that
the voltage is above 12.40. Voltage will drop more rapidly
in hot temperatures. If battery voltage drops below 12.40,
follow the battery recharge procedure in the Service
Manual.
•Check that the radiator coolant level of protection is to
at least -20°F (-29°C).
•Block the wheels. Do not apply the parking brake.
•Make sure that all tires are inflated to the optimum
pressure.
•Cut blocks of plywood about the same size of the tires.
Cover each block with indoor/outdoor carpeting and
place them between the tires and concrete. This will
prevent tire flat spotting.
•For long term storage, remove the tires and put the
vehicle up on blocks. Stack the tires on plywood and
cover with a tarp to prevent flat spotting.
•Move the wiper blades away from the windshield.
NOTE:To help prevent the battery from discharging
during shorter periods of inactivity, perform the follow-
ing:
1. Make sure that the rear liftgate/decklid, hood, and
doors are completely closed.
2. Make sure that the remote transmitter is operating and
that the battery is good.
3. Make sure that the hood, rear liftgate and door
switches are in adjustment.
4. Use the remote transmitter to set the alarm.
