2. As soon as you cycle the ignition to the ON mode, you
will see the “Malfunction Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will
happen:
• The MIL will flash for about 10 seconds and then return
to being fully illuminated until you cycle the ignition
OFF or start the engine. This means that your vehicle’s
OBD II system is not ready and you should not proceed
to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off posi-
tion or start the engine. This means that your vehicle’s
OBD II system is ready and you can proceed to the I/M
station.
If your OBD II system is not 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 II 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 II system is
ready or not, if the MIL 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 MIL is on with the engine
running.
REPLACEMENT PARTS
Use of genuine MOPAR parts for normal/scheduled main-
tenance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by the
use of non-MOPAR parts for maintenance and repairs will
not be covered by the New Vehicle Limited Warranty.
DEALER SERVICE
Your authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your ve-
hicle. Refer to these Service Manuals before attempting any
procedure yourself.
NOTE: Intentional tampering with emissions control sys-
tems may void your warranty and could result in civil
penalties being assessed against you.450 MAINTAINING YOUR VEHICLE

conditions. This will usually clear as atmospheric condi-
