Oldsmobile 2004 Alero, Owner'S Manual, Page: 228 / 360

To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has a spring in it; if
you let go of the cap too soon, it will spring back to
the right.
{
CAUTION:
If you spill fuel 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 “hiss” noise to stop.
Then unscrew the cap all the way.
Be careful not to spill fuel. Don’t top off or overfill your
tank, and wait a few seconds after you’ve finished
pumping before you remove the nozzle. Clean fuel from
painted surfaces as soon as possible. See Cleaning
the Outside of Your Vehicle on page 5-85.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
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 3-32.
{
CAUTION:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the
station attendant. Leave the area immediately.
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 fit properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. See “Malfunction Indicator Lamp” in the
Index.
