Check Fuel Cap Message
Your vehicle's onboard 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 SEL/RESET
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
your 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 340 .
