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.
NOTE:The standard TIREFIT system (refer to What To
Do In Emergencies for more information) is specifically
designed to operate in conjunction with the TPM system,
and will not damage the sensors.
If your tire pressure is low, you should correct your tire
inflation pressure as soon as possible and inspect all of
your tires. Low tire pressure will cause the tire pressure
light to illuminate and the alert will sound. They will
remain on for the rest of the driving cycle, or until the tire
pressure is corrected.
In addition to monitoring tire pressures, the TPM system
also monitors faults within the system. If the TPM light
and alarm continue after the tire pressure has been
corrected, see your authorized dealer.
This device complies with part 15 of FCC rules and with
RSS-210 of Industry Canada. Operation is subject to the
following conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference that may be
received, including interference that may cause undes-
ired operation.

In the case of an emergency brake maneuver, keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the in-
creased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.
WARNING!
Significant over- or under-inflation of tires, or mix-
ing sizes of front or rear tires or wheels on the
vehicle can reduce braking effectiveness. Maintain
proper tire pressure and always use the tires and
wheels specified in this manual for your vehicle.
The anti-lock brake system conducts a low-speed self-test
at about 12 mph (20 km/h). If you have your foot lightly
on the brake while this test is occurring, you may feel
slight pedal movement. The movement can be moreapparent on ice and snow. The anti-lock brake system
pump motor makes a low humming noise during opera-
tion, which is normal.
WARNING!
Pumping of the brake pedal will diminish the effec-
tiveness of the anti-lock brakes and may lead to an
accident. Pumping makes the stopping distance
longer. Just press firmly on your brake pedal when
you need to slow down or stop.
NOTE:During severe braking conditions, a pulsing
sensation may occur and a clicking noise will be heard.
This is normal, indicating that the anti-lock brake system
is functioning.
The ABS malfunction indicator light in the instrument
cluster comes on with the key in the ignition switch
turned to the ON/RUN position, and should go out with
the engine running. If the ABS light does not illuminate

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
152 STARTING AND OPERATING

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.

Snow Tires
Some areas of the country require the use of snow tires
during winter. See the recommended snow type winter
tire applications in this section.
WARNING!
Your vehicle may be equipped with sport perfor-
mance tires that are optimized for driving in dry and
wet weather conditions. However, these tires have
reduced traction capability in snow and ice. When
driving your Crossfire in these conditions with these
tires, you must take special care to maintain control
and avoid accidents. We recommend that you equip
your vehicle with“SNOW”or“ALL SEASON”tires
on all four wheels for driving in snowy and icy
conditions.
If you need snow tires, the recommended size for the
front and rear tires is the same size as the original
equipment front tires. This size tire on the rear allows the
use of tire chains on the rear wheels. Selection of this size
tire also requires the purchase of two additional wheels
with the same size specification as the original equip-
ment front wheels.
Snow tires may have a lower speed rating than factory
equipped tires and may not match the maximum vehicle
speed.
Snow tires should not be operated at sustained speeds
over 75 mph (120 km/h).
154 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.

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, 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.
•Never 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.
•Failure to equip your vehicle with tires having
adequate 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 read-
ings. Check with your authorized dealer before
replacing tires with a different size.
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 patterns.
These effects can be reduced by timely rotation of 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 maintain
mud, snow and wet traction levels, and contribute to a
smooth, quiet ride.
Rotate your tires at intervals shown on the maintenance
schedules. More frequent rotation is permissible if de-
sired. The reasons for any rapid or unusual wear should
be corrected before rotating.
156 STARTING AND OPERATING

•If the vehicle will be subjected to freezing tempera-
tures, remove the battery and store it in a dry, well-
ventilated place. If the vehicle is not going to be driven
in the next three weeks, follow the battery recharge
procedure in the Service Manual, then disconnect the
battery at the negative terminal.
CAUTION!
Use care when disconnecting the remote positive
cable. It is connected to the battery and can short out
to any metal on the vehicle. Always tape or wrap the
exposed cable end to prevent electrical shorts.
Disconnecting the battery causes the engine control sys-
tem to lose memory of some“learned”functions. The
engine may run rough when first started after a battery
disconnect until the control module“relearns”these
functions.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.
