Loose Fuel Filler Cap Message

After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improp-
erly installed, or damaged. A loose fuel filler cap message
will be displayed in the instrument cluster. Tighten the
gas cap until a

ЉclickingЉ sound is heard. This is an

indication that the gas cap is properly tightened. 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 Malfunction Indicator Light (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 which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)

is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.

Normally, the OBD system will be ready. The OBD
system may not be ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system is determined not ready
for the I/M test, your vehicle may fail the test.
