2005 CHRYSLER CROSSFIRE engine light

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.
200 MAINTAINING YOUR VEHICLE

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 con-
verter will not require maintenance. However, it is im-
portant 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 involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation 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.

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.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.If you notice a change in the sound of the exhaust system,
or if exhaust fumes can be detected inside the vehicle, or
when the underside or rear of the vehicle is damaged,
have a competent technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams
or loose connections could permit exhaust fumes to seep
into the passenger compartment. In addition, inspect the
exhaust system each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide which is colorless and odorless. Breathing
it can make you unconscious and can eventually
poison you. Follow the above precautions to keep
your exhaust system as safe as possible.
