HONDA 2003 Insight - Owner's Manual - Manual (Page 251)

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.
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. If the system
still detects an evaporative system
leak after retightening the cap, the
malfunction indicator lamp may
come on (see page
).
Push the fuel fill door closed until
it latches. 6.
