1997 PONTIAC GRAND AM engine

Charging System Indicator Light
The charging system
indicator light will come on
briefly when you turn on the ignition, but the engine is
not running. The light will
go out when the engine
is stated.
If it stays on when your engine is running, or comes on
while you are driving, you may have a problem with the
electrical charging system.
It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while this
light is
on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.
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.
BRAKE
United States Canada
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.
2-60

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, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
A CAUTION:
Your brake system may not be working properly
if the brake system warning light is
on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on
if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes 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 regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti-lock brakes.
If the regular brake system warning
light is also on, you don’t have anti-lock brakes and
there’s a problem with your regular brakes. See “Brake
System Warning Light” earlier in this section.
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.
2-61

Enhanced Traction System Warning Light
(If Equipped)
ETS
OFF
With the Enhanced Traction
System (ETS), 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 Enhanced Traction System
and your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly. The Enhanced
Traction System warning light may come
on for the following reasons:
If you turn the system off by pressing the button on
the shift lever, the warning light will come on and
stay on.
To turn the system back on, press the button
again. The warning light should go
off. (See
“Enhanced Traction System” in the Index for
more information.)
The warning light will come on when you set your
parking brake with the engine running, and
it will
stay on if your parking brake doesn’t release fully.
If the system is turned on and the warning light stays
on after your parking brake is fully released,
it
means there’s a problem with the system.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system is turned on and the parking brake is fully
released, your vehicle needs service.
2-62

Enhanced Traction System Active Light
(If Equipped)
LOW
TRAC
When your Enhanced
Traction System is limiting
wheel spin, this light will
come on. Slippery road
conditions may exist if
the Enhanced Traction
System active light
comes on,
so adjust your
driving accordingly.
The light will stay on for a
few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
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
there to tell you when the 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!
A light will come on to the right of the gage when the
gage pointer moves beyond the normal operating zone.
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 manual shows what to
do. See “Engine Overheating” in the Index.
2-63

Low Coolant Warning Light
If this light comes on and
stays on, the vehicle should
be promptly pulled off the
road and the coolant level
checked. See “Engine
Coolant” in the Index.
If there are visible signs of steam see “Engine
Overheating” in the Index before opening the hood.
Malfunction Indicator Lamp
(Check Engine Light)
Your Pontiac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
CHECK
ENGINE
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
I1 is replaced by
Enhanced Diagnostics.) The CHECK
ENGINE 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.
2-64

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.
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.
2-65

If the Light Is On Steady
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. 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
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.
2-66

Oil Pressure Warning Light
If you have a problem with
your engine’s oil pressure,
this light may
stay on after
you start your engine, or
come on and stay on when
you are driving. This
indicates that oil is not
going through your engine
quickly enough to keep it
lubricated.
The engine could be low on oil, or could have some
other oil pressure problem. Have it fixed right away.
This light can come on briefly, which is normal and
doesn’t show a problem:
As a bulb check, the light comes on when you turn
your key to
RUN and goes off when the engine is
started.
If it doesn’t, be sure to have it fixed so it will
be there to warn you.
For the four cylinder engine, when idling at a stop
sign, the light may blink on and then off. In addition,
if you make a hard stop, the light may come on
for
a moment. 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 I
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
