1997 PONTIAC FIREBIRD fuel cap

If the Light Is On Steady Have you recently changed brands of fuel?
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap, The diagnostic system can determine if the fuel
cap has been left
off or improperly installed. A loose or
missing fuel cap will allow fuel
to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through
a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light
off,
Are you low on fuel?
As your engine starts to run
out of fuel, your engine may
not run as efficiently
as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect
this. Adding fuel should correct this
condition. Make sure to install
the fuel cap properly. It
will take a few driving trips to turn the light off. If
so, be sure to fuel your
vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine
not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may
go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more
of these conditions,
change the fuel brand
you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none
of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment
and
diagnostic tools to fix any mechanical or electrical
problems that
may have developed.

Check Gages Light When the gage pointer first indicates EMPTY (E) you
need to get more right away.
CHECK
GAGES
Fuel Gage
I
This warning light will
come on briefly when
YOU
are starting the engine. If
the light comes on and
stays on while you are
driving, check your gages
to see if they are in the
warning areas.
Your fuel gage shows about
how much fuel is in
your
tank. The gage works only
when the ignition switch is
in the RUN position. Here are four concerns some owners have had
about the
fuel gage. All these situations are normal and do not
indicate that anything
is wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads FULL
(F).
It takes more (or less) gas to fill up than the gage
reads. For example, the gage reads
1/2 full, but it
took more (or less) than half
of the tank's capacity to
fill it.
The gage moves
a little when you turn, stop or
speed up.
When you turn the engine off, the gage doesn't go
back to
EMPTY (E).

Air Conditioning (If Equipped)
I
The air conditioning system uses the same controls as
the heating system, except that the air control knob has
two extra settings, described below.
MAX: Provides maximum cooling or quick cool-down
on very hot days. This setting recirculates most of the air
inside your vehicle.
If it is used for long periods of time,
the air may become dry. This setting directs air through
the upper air vents,
A/C: Use for normal cooling on hot days. This setting
cools outside
air and c‘kts it through the upper air vents.
The i-111- conditioner cumpressor operates in MAX, AIC,
BI-LEVEL, BLEND and DEFROST when the outside
temperature is above freezing. When the
air conditioner
is on,
you may sometimes notice slight changes in
your vehicle’s engine speed and power. This is normal
because the system is designed to cycle the compressor
on and
off to keep the desired cooling and help
fuel economy.
Cooling
The air conditioner works best if you keep your
windows closed. On very
hot days, open the windows
just long enough for the hot air to escape.
1. Turn the air control knob to A/C for normal cooling.
For faster cooling, move the
knob to MAX.
2. Turn the temperature control knob to a
comfortable setting.
3. Move the fan control knob to the desired speed.

Two labels on your vehicle show how much weight it
may properly
carry. The Tire-Loading Information l'abel
found on the driver's
door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight that you can carry,
This weight is called the vehicle capacity weight and
includes the weight of all occupants, cargo, and all
nonfactory-installed options.

The other label is the Certification label, found on the
rear edge of the driver's door. It tells you the gross
weight capacity of your vehicle,
called GVWR (Gross
Vehicle Weight Rating). The GVWR includes the weight
of the vehicle, all occupants, fuel and cargo. Never
exceed
the GVWR for your vehicle, or the Gross Axle
Weight Rating
(GAWR) for either the front or rear axle.
And, if you do have a heavy load, you should spread
it out. Don't ca more than 100 lbs. (45 kg) in your
rear area.

Towing a Trailer
If you don’t use the correct equipment and drive
properly, you can lose control when you pull a
trailer. For example, if the trailer
is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull
a trailer only if you have followed all the
steps in this section.
Ask your Pontiac dealer for
advice and information about towing
a trailer
with your vehicle.
NOTICE:
Pulling a trailer improperly can damage your
vehicle and result in costly repairs not covered by
your warranty.
To pull a trailer correctly, follow
the advice in this part, and see your Pontiac
dealer
for important information about towing a
trailer with your vehicle.
Your vehicle can tow a trailer if it is equipped with the
3800 and 5.7L engines and proper trailer towing
equipment.
To identify what the vehicle trailering capacity
is for your vehicle,
you should read the inforrnation in
“Weight of the Trailer” that appears later in
this section.
But trailering is different than just driving your vehicle by
itself. Trailering means changes in handling, durability and
fuel economy. Successful, safe trailering
takes correct
equipment, and it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and
that of
your passengers. So please read this section carefully
before
you pull a trailer.

The cap is behind a hinged door on the left side of
your vehicle.
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.
6-6

While refueling, hang the cap inside the fuel door.
To take off the cap, turn it slowly to the left
(counterclockwise).
If you get gas0 le 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 Pontiac” in the Index.
