1998 PONTIAC FIREBIRD fuel

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.
L
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 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” 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
Checking Things Under the Hood
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:
0 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.
inside
of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
0 Bring the fill nozzle in contact with the
0 Don’t smoke while pumping gasoline.
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,
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.

Before closing the hood, be sure all the filler caps are on.
Then just pull the hood down and close it firmly.
Engine Oil
LOW
OIL
If the LOW OIL 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 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 is the yellow loop near
the
back of the engine.
Note: Do not check the
5.7L engine oil level after the
engine has sat overnight.
A higher than normal reading
might be obtained. Check oil level with the oil warm.
Shut
off the engine, wait a few minutes, and then
check the oil.
Turn
off the engine and give the oil a few minutes
to
drain back into the oil pan. If you don’t, the oil
dipstick might
not show the actual level.

SAE 5W-30 is best for your vehicle. However, you can
use SAE 1OW-30 if it’s going to be 0°F (-18°C) or

As shown in the chart, if you have the 3800 engine,
SAE low-30 is best for your vehicle. However, you
can use
SAE 5W-30 if it’s going to be colder than
60°F (16°C) before your next oil change. When it’s
very cold,
you should use SAE 5W-30. These numbers
on
an oil container show its viscosity, or thickness. Do
not use other viscosity oils, such as SAE 20W-50.
I NOTICE:
Use only engine oil with the American Petroleum
Institute Certiaed For Gasoline Engines
‘‘Starburst” symbol. Failure to use the
recommended oil can result in engine damage not
covered
by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20°F (-29”C), consider using either an SAE SW-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for
your engine
at extremely low temperatures.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
driver’s door, shows the correct inflation pressures
for
your tires when they’re cold. “Cold” means your vehicle\
has been sitting for at least three hours
or driven no
more than
I mile (1.6 km).
If you’ll be driving at high speeds (e.g., speeds of
100 mph (160 km/h or higher), where it is legal, set
the cold inflation pressure to the maximum inflation
pressure shown on the tire sidewall, or to
38 psi
(265 Wa), whichever is lower. See the example below.
When you end this high-speed driving, return to the cold inflation pressures shown on the Tire-Loading
Information label.
Example: You’ll find maximum load and inflation pressure
molded on the tire’s sidewall, in small letters, near the
rim flange. It will read something like this: Maximum
load
690 kg (1521 lbs.) 0 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high-speed driving at
38 psi (265 Wa).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right.
It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
0 Rough ride
0 Needless damage from road hazards.

Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your dealer or other service
outlets. Larger areas of finish damage can be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not
removed, accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan and
exhaust system even though they have corrosion
protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can
do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular
dark spots etched
into the paint surface.
Although no defect in
the paint job causes this, Pontiac
will repair, at no charge to the owner,
the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20
000 km) of purchase,
whichever
occurs first.
