While refueling, hang the fuel cap by the tether using
the hook located on the inside of the ®ller door.

(counterclockwise).
{CAUTION:
If you get fuel on yourself and then something
ignites it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap too
quickly. This spray can happen if your tank is
nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any
ªhissº noise to stop. Then unscrew the cap all
the way.
Be careful not to spill fuel. Clean fuel from painted
surfaces as soon as possible. See
Cleaning the Outside
of Your Vehicle on page 5-91.

When you put the fuel cap back on, turn it to the right

sure you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. this would allow fuel to evaporate into the
atmosphere. See
Malfunction Indicator Lamp on
page 3-41.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer can get one for you.
If you get the wrong type, it may not ®t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See ªMalfunction Indicator Lampº in the
Index.
