1997 PONTIAC FIREBIRD engine

Voltmeter
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.
Brake System Warning Light
Your Pontiac’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can
still work and stop you.
For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem or the brake fluid level could
be low. Have your
brake system inspected right away.
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 air conditioning and audio system.
BRAKE
This light should come on
briefly when you turn
the ignition key to
RUN. If
it doesn’t come on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
If the light comes on while you are driving, pull off the
road and stop carefully.
You may notice that the pedal is
harder to push. Or, the pedal may
go closer to the floor.
It may take longer to stop. If the light is still on, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake

System Warning Light” and “Towing Your Vehicle” in Anti-Lock 1- System Warning Eight
the Index.)
Your braKe s cem may not be working properly

Traction Control System Warning Light
(If Equipped)
I
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 off the road
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
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
TCS
OFF
This warning light should
come on briefly as you start
the engine.
If the. warning
light doesn’t come on then,
have it fixed
so it will be
ready to warn you if there’s
a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.
If your brakes begin to overheat, the brake portion of the
traction control system will shut down, but the throttle
and engine spark control will continue
to work. The
warning light will not come on when this happens.

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.
Low Coolant Light (VS Engine)
This warning light should
come on while you are
starting your engine.
If the
light doesn’t
come on, have
it repaired.
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 manual shows what to
do. See “Engine Overheating” in the Index. 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.

NOTICE:
Driving with the LOW COOLANT light on could
cause your Pontiac
to overheat. See 66Engine
Overheating”
in the Index. Your Pontlac could
be damaged and
it wou1dn”t be covered by
your warranty.
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. 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. This 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,
2-84

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
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.
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 vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are 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, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
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.
2-85

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.

\‘O ii
0
V6 Engine VS Engine
One of these gages may tell you 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 kPa (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.
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and
is not covered by
your warranty.
