ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your Crossfire is equipped with a sophisti-
cated onboard diagnostic system called OBD II. This
system monitors the performance of the emissions and
engine control systems. When these systems are operat-
ing properly, your vehicle will provide excellent perfor-
mance and fuel economy, as well as engine emissions
well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the CHECK ENGINE Light. It will also store
diagnostic codes and other information to assist your
service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.CAUTION!
Prolonged driving with the CHECK ENGINE light
on could cause further damage to the emission
control system. It could also affect fuel economy and
drivability. The vehicle must be serviced before any
state emissions tests can be performed.
If the CHECK ENGINE light is flashing, severe catalytic
converter damage and power loss will soon occur. Im-
mediate service is required.
If the gas cap is not tightened properly, the CHECK
ENGINE light may come on. Be sure the gas cap is
tightened every time you add fuel. Tighten the cap until
you hear it “click” once.

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies
the following: the CHECK ENGINE Light is functioning
and is not on when the engine is running, and that the
OBD (Onboard Diagnostic) system is ready for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle’s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.2. Turn the ignition to the ON/RUN position, but do not
crank or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON/RUN
position, you will see your CHECK ENGINE light come
on as part of a normal bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The CHECK ENGINE light will flash for about 10
seconds and then return to being fully illuminated
until you turn off the ignition key or start the
engine. This means that your vehicle’s OBD system
isnot readyand you shouldnotproceed to the I/M
station.
b. The CHECK ENGINE light will not flash at all
and will remain fully illuminated until you turn off
the ignition key or start the engine. This means that
your vehicle’s OBD system isreadyand you can
proceed to the I/M station.

If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD system is
ready or not ready, if the CHECK ENGINE light is
illuminated during normal vehicle operation, you should
have your vehicle serviced before going to the I/M
station. The I/M station can fail your vehicle because the
CHECK ENGINE light is on with the engine running.REPLACEMENT PARTS
Use of genuine Moparparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Moparparts for maintenance
and repairs will not be covered by the warranty offered
by DaimlerChrysler Corporation.
DEALER SERVICE
Your dealer has the qualified service personnel, special
tools and equipment to perform all service operations in
an expert manner. Service Manuals are available which
include detailed service information for your Crossfire.
Refer to these manuals before attempting any procedure
yourself.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
208 MAINTAINING YOUR VEHICLE
Change Engine Oil
The oil change interval for your Crossfire is initially set at
7,000 miles (Canada: 11,000 km).
The Flexible Service System (FSS) in your vehicle evalu-
ates engine temperature, oil level, vehicle speed, engine
speed, distance driven, and the time elapsed since your
last service. It determines when your vehicle needs
maintenance service and alerts you in advance. The next
necessary service is indicated by the FSS in your instru-
ment cluster.
NOTE:Also see the FSS system details in the Under-
standing Your Instrument Panel section of this manual.
Very light duty driving cycles (most trips more than 10
miles [16 km] at moderate speeds in moderate tempera-
ture conditions) can extend the service interval beyond
7,000 miles (Canada: 11,000 km).
IfANYof the following apply to your driving, the oil
change interval can be reduced significantly:
•Day and night temperatures are below 32°F (0°C)
•Stop-and-go driving
•Extensive engine idling
•Driving in dusty conditions
•Short trips of less than 10 miles (16 km)
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
•Taxi, Police, or delivery service (commercial service)
Observe the oil change interval indicated by your FSS
system. This system will monitor the driving conditions
seen by your vehicle, and will recommend the best
interval for servicing your vehicle to maintain it in top
condition.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly serviced to assure proper catalyst
operation and prevent possible catalyst damage.
If the CHECK ENGINE light is flashing, immediate
service is required.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In the
event of engine malfunction, particularly involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera-
tion of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in possible
damage to the converter and the vehicle.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to DaimlerChrysler Corpo-
ration’s specifications, should be obtained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.

Windshield Washer Reservoir
The washer fluid reservoir is located in the engine
compartment and should be checked for fluid level at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) rated not to
freeze at -25°F (-31°C). Operate the system for a few
seconds to flush out the residual water.WARNING!
Do not overfill the washer reservoir. Do not attempt
to fill to the top of the filler neck. Fluid may leak out
onto the floor or driveway causing a potential slip
and fall hazard. When the indicator light first illu-
minates, the maximum fill amount is 1 gallon or 4
liters.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
220 MAINTAINING YOUR VEHICLE
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. Fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be checked
when pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.Use brake fluid approved to MB 331.0, or a DOT 4 brake
fluid with: minimum dry boiling point (ERBP) 500°F,
minimum wet boiling point (WERBP) 356°F, maximum
viscosity 1500 mm
2/s, conforming to FMVSS 116 and
ISO 4925.
WARNING!
Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident.
WARNING!
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign mat-
ter. Use of contaminated fluid may result in reduced
brake performance or a sudden brake failure. You
could have an accident.

ammonia based cleaners to clean your leather upholstery.
Application of a leather conditioner is not required to
maintain the original condition.
CAUTION!
The use of vinyl, leather or plastic protectants may
cause excessive gloss and/or discoloration of interior
trim parts.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with any commercial household-type glass cleaner.
Never use an abrasive-type cleaner. Use caution when
cleaning inside rear windows equipped with electric
defrosters. Do not use scrapers or other sharp instru-
ments which may scratch the elements.
Instrument Panel Cover
The instrument panel cover has a low glare surface which
minimizes reflections in the windshield. Do not use
protectants or other products which may cause undesir-
able reflections. Use soap and warm water to restore the
low glare surface.
