FUEL FILL CAP
Gasoline is highly flammable
and explosive. You can be
burned or seriously injured
when handling fuel.
Stop the engine and keep
heat, sparks, and flame away.
Handle fuel only outdoors.
Wipe up spills immediately.

Shift to Park or Neutral and set
the parking brake. Pull the hood
release handle located under the
lower lef t corner of the dashboard.
The hood will pop up slightly.
Push the f uel f ill door closed until
it latches.
Stop f illing the tank af ter the f uel
nozzle automatically clicks of f . Do
not try to ‘‘top of f ’’ the tank, leave
some room f or the f uel to expand
with temperature changes.
Your car has an on-board ref ueling
vapor recovery system to help
keep f uel vapors f rom going into
the atmosphere. If the fuel nozzle
keeps clicking of f even though the
tank is not f ull, there may be a
problem with this system. Consult
your dealer.
Screw the f uel f ill cap back on,
tighten it until it clicks several
times. If you do not properly
tighten the cap, the Malfunction
Indicator Lamp may come on (see
page ).
Put the attachment on the fuel fill
cap into the slit on the f uel f ill door.

inspect your car if this indicator
comes on repeatedly, even though it
may turn of f as you continue driving.
This indicator should light when the
ignition switch is ON (II), and go out
af ter the engine starts. If it comes on
at any other time, it indicates one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your car’s perf ormance, it can
reduce your f uel economy and cause
your car to put out excessive
emissions. Continued operation may
cause serious damage. If you have recently ref ueled your
car, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is
missing. Tightening the cap will not
make the indicator turn of f
immediately; it takes at least one
driving trip.
If the indicator remains on, or the
f uel cap was not loose or missing,
have the car checked by the dealer
as soon as possible. Drive
moderately until the dealer has
inspected the problem. Avoid f ull-
throttle acceleration and driving at
high speed.
