ONBOARD DIAGNOSTIC SYSTEM —
OBD II
Your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This
system monitors the performance of the emis-
sions, engine, and automatic transmission con-
trol systems. When these systems are operat-
ing properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the “Malfunction
Indicator Light (MIL).” It will also store diagnos-
tic 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 MIL on could
cause further damage to the emission con-
trol system. It could also affect fuel
economy and drivability. The vehicle must
be serviced before any emissions tests can
be performed.
• If the MIL is flashing while the engine is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a “gASCAP” message
will display in the odometer or a “CHECK
gASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC).
Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument
Panel” for further information. Tighten the gas
cap until a ⬙clicking⬙ sound is heard. This is an
indication that the gas cap is properly tight-
ened.
Press the odometer reset button to turn the
message off. If the problem persists, the mes-
sage will appear the next time the vehicle is
started. This might indicate a damaged cap. If
the problem is detected twice in a row, the
system will turn on the MIL. Resolving the
problem will turn the MIL light off.
REPLACEMENT PARTS
Use of genuine MOPAR姞 parts for normal/
scheduled maintenance and repairs is highly
recommended to ensure the designed perfor-
mance. Damage or failures caused by the use
of non-MOPAR姞 parts for maintenance and
repairs will not be covered by the manufactur-
er’s warranty.
