Acura 2007 TL - Owner's Manual - Manual (Page 239)

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. even
though the tank is not full, there may
be a problem with your vehicle’s fuel
vapor recovery system. The system
helps keep fuel vapor from going
into the atmosphere. Try filling at
another pump. If this does not fix the
problem, consult your dealer.
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, and the
malfunction indicator lamp may
also come on (see page
).
Push the fuel fill door closed until
it latches.
