Check 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 ''CHECK FUEL CAP'' message
appears on the 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
display, press the trip button. The
''CHECK 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 187 .
