2003 PONTIAC BONNEVILLE open gas tank

While refueling, hang the tethered fuel cap on the hook
on the inside of the fuel door.
-I- I u rewluve t11e luei ti~~p, ~UCI-I it Si&y t~ the kft I,- - 1
(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. 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
“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 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 improperlv
installed. This would allow fuel to evaporate into the
atmosphere. See
Malfunction Indicator Lamp on
page
3-46.

If your vehicle has the optional Driver Information
Center (DIC), the CHECK
GAS CAP message will be
displayed
if the fuel cap is not properly reinstalled.
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.
Fuel Door Lock
On models having the optional theft-deterrent system,
the fuel door is locked and unlocked together with
the driver’s power door lock.
To unlock the fuel filler
door, use the power door lock button or the remote
keyless entry transmitter (if equipped). If your
vehicle has a fuel door lock, the fuel door can be
opened manually
in case of an electrical power
failure.
The release mechanism is on the driver’s side of the
vehicle, at the top of
the trunk compartment.
Pull the tab to release the
fuel door.
Notice: Prying on a locked fuel filler door can
damage
it. Use the remote fuel door manual release
located in the trunk in the case of a power failure.
