5. Screw the fuel fill cap back on until
it clicks at least once. If you do not
properly tighten the cap, you will
see a
‘‘TIGHTEN FUEL CAP’’
message on the multi-information
display (see right column on this
page), and the malfunction
indicator lamp may also come on
(see page
437 ).
6. Push the fuel fill door closed until
it latches.
Tighten Fuel Cap Message
Your vehicle's on board diagnostic system
will detect a loose or missing fuel fill cap as
an evaporative system leak. The first time a
leak is detected a
‘‘TIGHTEN FUEL CAP’’
message appears on the multi-information
display. Turn the engine off, and confirm
the fuel fill cap is installed. If it is, loosen it,
then retighten it until it clicks at least once.
The message should go off after several
days of normal driving once you tighten or
replace the fuel fill cap. To scroll to another
message, press the INFO button. The
‘‘TIGHTEN FUEL CAP’’ message will
appear each time you restart the engine
until the system turns the message off.
If the system still detects a leak in
the vehicle's evaporative emissions
system, the malfunction indicator
lamp (MIL) comes on. If the fuel fill
cap was not already tightened, turn
the engine off, and check or
retighten the fuel fill cap until it
clicks at least once. The MIL should
go off after several days of normal
driving once the cap is tightened or
replaced. If the MIL does not go off,
have your vehicle inspected by a
dealer. For more information, see
page
437 .
