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.

may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis

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.

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.
2-85
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

come on briefly when you
are starting the engine. If
the light comes on and stays
on while you are driving,

Avoid needless heavy bralung. Some people drive in
spurts --.heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool b’etween
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate
a lot of unnecessary braking. That means
better braking and longer brake
life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes.
If you do, the
pedal may get harder to push down. If your engine
stops,
you will still. have some power brake assist. But
you will use
it when you brake. Once the power assist is
used up, It may take longer to stop and the brake pedal
will be harder
to push. , ,.
Anti-Lock Brakes
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will
help
prevent a braking skid.
When you start your engine, or when you begin to drive
away, your
anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test
is going on, and you ,may even notice that your
brake pedal moves a little.
This is normal.
ABS
INOP
If there’s a problem with the
anti-lock brake system, this
warning light will stay on or
flash, See “Anti-Lock
Brake System Warning
Light”
