•
Access, or allow others to access, information
stored in your vehicle systems, including personal
information.
For further information, refer to “Cybersecurity” in the
“Understanding Your Instrument Panel” section.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check fuel cap” message will be displayed in the instru-
ment cluster display. Refer to “Instrument Cluster Display”
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
tightened.
Push 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 may not be ready if your vehicle was recently
serviced, or recently had a dead battery or a battery
replacement. If the OBD II system should be determined
not ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is
ready , you must do the follow-
ing:
1. Cycle the ignition to the ON mode, but do not crank or
start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
