1998 PONTIAC GRAND PRIX Owners Manual

Filling Your Tank The cap is behind the fuel door on the left side of
your vehicle.
1 A CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don’t
smoke if you’re near gasoline or refueling
your vehicle. Keep sparks, flames and
smoking
materials away from gasoline.
While refueling, hang the cap by the tether from the pin
on the fuel door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap
has a spring in it; if you let
go of the cap too soon, it will spring back to the right.

A CAUTION: I
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 Vehicle” in the Index. When you put the cap back on, turn
it 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” in the Index.
.
NOTICE:
If you need a new 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 your fuel tank and emissions system may
be damaged. See “Malfunction Indicator Lamp”
in the Index.

Filling a Portable Fuel Container
A 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.
0 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.
0 Bring the fill nozzle in contact with the
1 inside of the fill opening before operating
the nozzle. Contact should be maintained
1 until the filling is complete.
~ 0 Don’t smoke while pumping gasoline.
i
Checking Things Under the Hood
A CAUTION: I
An electric fan under the hood can start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
1 oil, coolant, brake fluid, windshield washer and
other fluids, and plastic
or rubber. You or others
could be burned. Be careful not to drop or
spill
things that will burn onto a hot engine.

3800 Supercharged Engine
(If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This air, mixed with fuel, creates increased engine
power. Since the supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the supercharger is pumping is routed through a bypass.
All of these controls working together provide high
performance character and fuel efficiency
in the
3800 Supercharged engine.
Engine Oil
LOW OIL
LEVEL
If the LOW OIL LEVEL
light on the instrument
panel comes on, it means
you need to check
your
engine oil level right away.
For more information, see “Low
Oil Level Light” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick
handle is the yellow loop
near the front of the engine.
