2002 BUICK PARK AVENUE fuel pump

2-87
Here are some things that some owners ask about. None
of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

It takes more (or less) fuel to fill up than the gage
indicated. For example, the gage may have indicated
half full, but it took more (or less) than half the
tank's capacity to fill it.

The gage moves up a little when you turn a corner,
speed up or make a hard stop.

The gage doesn't go back to empty when you turn
off the ignition.
Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver
Information Center (DIC). The DIC will display
information about how your vehicle is functioning,
as well as warning messages if a system problem
is detected.
The following buttons are
on the DIC control panel
located to the left of the
steering column:
ODO/TRIP (Odometer/Trip): Use this button to
display your total and trip miles.
FUEL INFO (Information): Press this button to
display fuel information such as fuel used, fuel range
and fuel economy.
GAGE INFO (Information): Use this button to display
oil pressure, oil life, coolant temperature, tire pressure
and battery information.
RESET: This button, used along with other buttons, will
reset system functions.
ENG/MET (English/Metric): Use this button to change
the display between English and metric units.

6-4 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. Gasolines
meeting these specifications could provide improved
driveability and emission control system performance
compared to other gasolines.
In Canada, look for
the ªAuto Makers'
Choiceº label on
the pump.
Canada Only
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 ªMalfunction
Indicator Lampº in the Index) 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
Some gasolines that are not reformulated for low
emissions may contain an octane
-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask the attendant where you buy gasoline whether the fuel
contains MMT. General Motors does not recommend the
use of such gasolines. Fuels containing MMT can reduce
the life of spark plugs and the performance of the emission
control system may be affected. The malfunction indicator
lamp may turn on. If this occurs, return to your authorized
GM dealer for service.

6-8
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 ªMalfunction Indicator Lampº in
the Index.
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 ªMalfunction Indicator
Lampº in the Index.
Filling a Portable Fuel Container
CAUTION:
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged if this
occurs. To help avoid injury to you and others:

Dispense gasoline only into
approved containers.

Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed or
on any surface other than the ground.

Bring the fill nozzle in contact with the
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.

Don't smoke while pumping gasoline.
