The system,does this
to prevent damage from
overheating.

Low Traction Light
LOW
TRAC
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
If you have the traction control system, this light will
also come on when the system is limiting wheel spin.
Slippery road conditions may exist if the low traction
light comes
on, so adjust your driving accordingly. The
light will stay on for a few seconds after the anti-lock
system stops adjusting brake pressure or the traction
control system stops limiting wheel spin.
The low traction light also comes
on briefly wlien you
turn the ignition key to
RUN. If the light doesn’t come
on then, have
it fixed so it will be there to tell you
when the anti-lock brake system or traction control
system
is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If ’
‘the gage pointer moves
into the red area, your
engine is too hot! It means
that your engine coolant
has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road”, this section
shows what to
do. See “Engine Overheating” in the Index.

LOW
COOLANT
I
This warning light should
come on while
you are
starting your engine. If the
light doesn’t come on, have
it repaired.
Your Firebird
is equipped with a LOW COOLANT
indicator which is designed to detect when the coolant
level
drops below set limits. If the low coolant level
sensor (on the radiator)
drops while the engine is
running, ‘the LOW COOLANT indicator will light
and remain lit until the ignition switch is turned to
the
OFF position. Check coolant level and add coolant
as needed. The LOW COOLANT light might stay on
after filling the radiator., Turn the ignition switch to the
OFF position, then restart the engine to verify that the
LOW COOLANT light goes out. See “Engine Coolant”
in the Index.

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.
ProCarManuals.com

Have you recently changed brands of fuel?
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
conditijons 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 this condition, 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.
Engine Oil Pressure Gage
This gage tells you if there
could be
a problem with
your engine oil pressure.
The engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) in the United
States, or Wa (kilopascals)
in Canada, when the engine
is running. Oil pressure should be 20 to 80 psi (140 to
550 kPa). On the 3800 engine the oil pressure should be
between
20 and 120 psi (140 to 827 kPa). It may vary
with engine speed, outside temperature and oil viscosity,
but readings above the red area show the normal
operating range. Readings in the red area tell
you that
the engine is low on oil, or that you might have some
other oil problem. See “Engine Oil” in the Index.

ProCarManuals.com

Don’t keep driving if the oil pressure is low. If
you do, your engine can become
so hot that it
catches fire.
You or others could be burned.
Check your
oil as soon as possible and have your
vehicle serviced.
NOTICE:
I
Damage to your engine from neglected oil
problems
can be costly and is not covered by
your warranty.
Low Oil Light
LOW OIL
Your vehicle is equipped with an oil level monitoring
system. When
you start your engine, the waning light
will come
on briefly. If the light doesn’t come on, have
it repaired.
If the light stays on after starting your engine, your
engine oil Level may be too
low. You may need to add
oil.
See “Engine Oil” in the Index.

ProCarManuals.com

NOTICE:
The oil level monitoring system only checks the oil level when you are starting your engine. It does not
keep monitoring the level once your
engine is running.
Also, the oil level check only
works when the engine has been turned
off long
enough for the oil to drain back into the oil pan.
Check Gages Light
CHECK GAGES
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.
Fuel Gage
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.

When the gage pointer first indicates EMPTY (E), you
still have a little fuel left (about one to two gallons), but
you need
to get more right away.
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.
