gas type PONTIAC BONNEVILLE 2003 Owners Manual

Gasoline Specifications
It is recommended that gasoline meet specifications
which were developed by the American Automobile
Manufacturers Association and endorsed by the
Canadian Vehicle Manufacturers Association for better
vehicle performance and engine protection. Gasoline
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasoline.
Canada Only
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.
California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications.
If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may
turn on (see
Malfunction lndicator Lamp on page 3-46 )
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work
properly. You should not have to add anything to your
fuel. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be
available in your area to contribute to clean air.
General Motors recommends that you use these
gasolines, particularly if they comply with the
specifications described earlier.

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.
