Malfunction Indicator Lamp (Service Engine Soon Light)
I SERVICE ~
ENGINE
SOON
..
A computer
monitors operation of your fuel, ignition
and emission control systems. This light should come on
when the ignition is on, but the engine
is not running, as
a check to show you it is working. If it does not come on
at
all, have it fixed right away. If it stays on, or it comes
on while
you are driving, the computer is indicating that
you have a problem. You should take your vehicle in for
service soon.
NOTICE:
If you keep driving your vehicle with this light
on, after a while the emission controls won’t
work as well, your fuel economy won’t be as good
and your engine may not run as smoothly. This
could lead to costly repairs not covered by your
warranty.
OBD I1 3.8L Engine (Code K)
Certain vehicles are equipped with a new emission
diagnostic system. You can tell whether your vehicle has
this system by reading our tune-up label located under
the hood.
If the label says OBD 11 on it, the following
instructions apply.
Your Pontiac Firebird is equipped with an onboard
computer which monitors operation of the emission
control system. This system is called OBD
11 (On-
Board Diagnostics-Second Generation) and is intended
to assure that emissions
are at acceptable levels for the
life
of the vehicle, helping to produce a cleaner
environment. The SERVICE
ENGINE SOON light
comes on to indicate when service is required.
Malfunctions often will be indicated by the system

before any problem is apparent, which may prevent more serious damage to your vehicle. The system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
The SERVICE ENGINE SOON light should come on,
as
a check to show you it is working, when the ignition
is on and the engine is not running. This light will also
come on during a malfunction in one or two ways:
Light on steady - - indicates a system malfunction
has been detected. Drive the vehicle to the dealer for
service at your first opportunity.
Light Flashing - - indicates a misfire has been
detected which may damage the emission control
system. The damage may be reduced'by lowering the
vehicle speed, reducing the amount of cargo being
hauled or trailered, avoiding hard acceleration, or by
avoiding steep uphill grades.
If these actions are
effective, the light will stop flashing and remain on
steady. Drive the vehicle to a dealer for service.
If
the light continues to flash, stop the vehicle. Wait for
a steady light to come on, then drive the vehicle to
the nearest dealer for service.
These following conditions also may cause the
SERVICE ENGINE
SOON light to come on.
Low Fuel/Out of Fuel - - As the vehicle starts to run out
of fuel the SERVICE ENGINE SOON light may come
on as a result of
an engine misfire. Filling your gasoline
tank should correct this condition. Make sure to install
the gas cap fully. It will require a few driving trips to
turn the light
off.
Poor Quality Fuel - - Be sure to fuel your vehicle with
quality fuel. Your engine may not run efficiently on poor
fuel. Poor fuel may cause stalling, hesitation or misfire.
These conditions may go away when the engine is
warmed-up. However, poor quality fuel may cause the
SERVICE ENGINE SOON light to come
on.
Have a dealer check the vehicle. If no problems are
found, you may want to change to another brand of fuel.
Driving Through Standing Water -- Driving your
vehicle through puddles
of deep standing -w.a&r may
result in a temporary misfire condition. This condition
will usually correct itself- shortly after the electrical
system dries out.
It will require a few driving trips to
turn the light off.

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes, or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight, and
extreme heat.
If they aren’t, they may not operate
properly
or cause failure of the tape player.
Cassettes are subject to wear and the sound quality may
degrade over time. Always verify that the cassette tape
is in good condition and that the tape player is clean
before obtaining service on your tape player.
Your tape player should be cleaned with every 50 hours
of use to provide optimum performance. Your radio may
display “Cln” to indicate that your have used your tape
player for
50 hours without resetting the tape clean
timer.
If you notice a reduction in sound quality,
regardless of when the tape player was last cleaned, try
playing a different cassette to see if the tape or the tape
player is at fault. If the second cassette results in no
improvement in sound quality, try cleaning the tape
player.
Proper tape player cleaning should be done with a
scrubbing action, nonabrasive cleaner cassette. This is a
wet-type cleaning system that uses a cleaning cassette
with pads which scrub the tape head as the hubs of the
cleaner cassette
turn. To properly clean your tape player,
follow the instructions with the cleaning cassette.
If you
use this type of cleaner, the radio may display an error
and eject the cartridge. This is normal and is the result
of an added feature in the tape player that detects broken
tapes. If an error occurs, you will need to insert the
cleaning cassette at least three times to thoroughly clean
the tape player.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head.
This type of cleaning cassette will not
eject. It may not clean as thoroughly as the scrubbing
type cleaner.
A scrubbing action cleaner is available through your
dealer
(GM Part No. 12344600).
Note: Tape adapter kits for portable CD players will not
work in your cassette player. These adapters will cause
the radio to display an error message and the adapter
cassette will be ejected.

The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to
think you are going
slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must
start when you’re not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that First part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go.
If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
Pontiac dealerships all across North America. They’ll
be ready and willing to help if you need it.
Here are some things you can check before a trip:

Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Highway Hypnosis
Is there actually such a condition as “highway
hypnosis”? Or is it just plain falling asleep at the wheel?
Call it highway hypnosis, lack
of awareness, or
whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Don’t let
it
happen to you! If it does, your vehicle can leave the
road in
less than a second, and you could crash and be
injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
0 If you get sleepy, pull off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as an emergency.

Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a
hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to
do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your parking
brake, and then shift to PARK (P), or REVERSE (R)
for a manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more on this. Things that
are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belts, cooling
system, and brake adjustment. Each
of these is covered
in this manual, and the Index will help you find them
quickly.
If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

Attach the cable at least 18 inches (45 cm) away
from the dead battery, but not near engine parts that
move. The electrical connection is just as good there,
but the chance
of sparks getting back to the battery is
much less.
Now start the vehicle with the good battery and run the engine for a while.
Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably needs
service.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.

Towing Your Car
Try to have a GM dealer or a professional towing
service tow your Pontiac. The usual towing equipment is
a sling-type
(A) or a wheel-lift (B) or car carrier (C) tow
truck.
If your vehicle has been changed or modified since it
was factory-new
by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
0
0
0
0
0
That your vehicle cannot be towed from the front or
rear with sling-type equipment.
That your vehicle has rear-wheel drive.
The make, model, and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let the tow'operator.
know that this manual contains detailed towing
instructions and illustrations. The operator may want to
see them.

When your vehicle is being towed, have the ignition key
off. The steering wheel should be clamped in a
straight-ahead position, with a clamping device
designed for towing service. Do not use the car’s
steering column lock for this. The transmission should
be in “Neutral” and the parking brake released.
Don’t have your vehicle towed on the rear wheels,
unless you must. If the vehicle must be towed on the
rear wheels, don’t go more than
35 mph (55 km/h) or
farther than
50 miles (80 km) or your transmission will
be damaged. If these limits must be exceeded, then the
rear wheels have to be supported on a dolly.
