1996 PONTIAC FIREBIRD engine

Warning lights come on when there my be or is a
problem with one of your vehicle’s functions. As YQU
will see in the details on the next fay pages, some
warning lights come on briefly when you start the
engine
just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when
this happens.
Gages can indicate when there may be
or is a problem
with one
of your vehicle’s functions. Often gages md
warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one o’f the gages shows
there may be a problem, check the section that tells you
what to
do about it. Please follow this manual’s advice.
Waiting to
do repairs can be costly -- and even
dangerous. So please get to know your warning lights
and gages. They’re
a big help.

turn your ignition to
RUN
or START. Then the light
should go out. This means
the system is ready.

start your vehicle, or stays on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.
Voltmeter
I p4
You can read battery
voltage on
your voltmeter.
If it reads less than 11 volts
or more than 16 volts while
your engine
is running,
and it stays there, you may
have
a problem with the
electrical charging system.
Have it checked right away. Driving with the voltmeter
reading in a warning zone could drain your battery.
If you idle your engine for a while, the voltmeter
reading might move into the yellow zone, If the reading
stays in the yellow zone while you are driving, you may
have a problem with the electrical charging system.
Have it checked. While the voltmeter reads in the
yellow
zone, your battery may not be able to power certain
electrical accessories,
like ABS. (If this happens, your
ABS INOP light will come on. See “Anti-Lock Brake
System Warning Light” in this
part.)
If you must drive a short distance with the voltmeter
reading in a warning zone,
turn off all your accessories,
including your comfort control and audio system.

, may go closer to the floor. It may take longer to stop.
Your regular brake system may not be working
properly
if the anti-lock brake system warning
light is flashing. Driving with the anti-lock
brake system warning light flashing can lead
to an accident. After you’ve pulled

and stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition
off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset
the
system. If the light still stays on, or comes on again
while you’re driving, your Pontiac needs service.
If the
light is on but not flashing and the regular brake system
warning light isn’t on, you still have brakes, but you
don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on
briefly when you turn the ignition key to RUN. If the

Malfunction Indicator Lamp (Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Pontiac is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
. . , , ..** , .- ,_ , . ,I , - . 'G, .. .. . .. .-
This system is called OBD I1 (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. (In Canada, OBD
11 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
light comes on to indicate that there is a problem and
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. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may
not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running:If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0 Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service
is required.
0 Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer
or qualified service center diagnosis and
service may be required.

If the Light Is Flashing
The following may prevent more serious damage to
your s&ide:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If towing a trailer, reduce the amount of cargo being
hauled
as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.
If the light continues to flash, whenit is safe to do so, ’
stop the vehicle. Put your vehicle in PARK (P). Turn the
key
off, wait at least 10 seconds and restart the engine.
If the light remains on steady, see “If the Light Is On
Steady” following.
If the light is still flashing follow the
previous steps, and drive the vehicle to your dealer or
*qualified service center for service.
If the Light Is On Steaay
You may be able to correct the emission system
malfunction by considering
the following:
Did you just 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. This will
dow fuel to evaporate into the atmosphere. A few
driving trips
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your el’ectrical 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 bun 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.
