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 emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though 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 control system. It
could also affect fuel economy and driveability.
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
608 MAINTAINING YOUR VEHICLE

“Electronic Vehicle Information Center (EVIC)” in ”Un-
derstanding Your Instrument Panel” for further informa-
tion. 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 message 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.
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 that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
Indicator Light (MIL)” is functioning and is not
on when the engine is running, and that the OBD II
system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.

MAINTAINING YOUR VEHICLE 609

Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any of these conditions
are present, clean the wiper blades or replace as neces-
sary.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the engine
compartment and should be checked at regular intervals.
Fill the reservoir with windshield washer solvent (not
radiator antifreeze) and operate the system for a few
seconds to flush out any residual water.
The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates.
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.
After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. MOPAR® All
Weather Windshield Washer Solution or equivalent, used

MAINTAINING YOUR VEHICLE 623

•Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
•Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering and fill as needed.
•Check function of all interior and exterior lights .
Required Maintenance Intervals.
Refer to the maintenance schedules on the following
page for the required maintenance intervals.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter.
•Rotate the tires.Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system
turns on.
•Inspect battery and clean and tighten terminals as required.
•Inspect brake pads, shoes, rotors, drums, hoses and park brake.
•Inspect engine cooling system protection and hoses.
•Inspect exhaust system.
•Inspect engine air cleaner if using in dusty or off-road conditions.
