The cap is behind a hinged door on the left side of
vour vehicle.
While refueling, hang the
cap inside the fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any "hiss" noise to stop. Then unscrew
the
cap
all the way.
~ ~~
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See "Cleaning the
Outside of Your Pontiac" in the Index.
