2002 PONTIAC GRAND PRIX warning

2-80
Charging System Indicator Light
The charging system
light will come on briefly
when you turn on the
ignition, as a check to
show you it's working.
Then it will go out.
If it stays on, 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 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 vehicle'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 is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on when you turn the 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.

2-81
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 ªTowing Your Vehicleº in
the Index.
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, the light will
come on when your engine
is started and may stay
on for three seconds.
That's normal.
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 vehicle needs service. If the
light is on 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.

2-82
Traction Control System Warning Light
(3800 Supercharged V6 Engine Only)
The traction control
system warning light
may come on for the
following reasons:

If you turn the system off by pressing the TCS
button located on the far right side of the trip
computer, 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 ªTraction Control Systemº in the Index
for more information.

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Enhanced Traction System Warning Light
(3100 V6 or 3800 V6 Engine)
The Enhanced Traction
System warning light
may come on for the
following reasons:

If you turn the system off by pressing the TRAC
button on the far right side of the Driver Information
Center or trip computer (if equipped), 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 ªEnhanced Traction Systemº in
the Index for more information.

If the Enhanced Traction System warning light
comes on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. Adjust your driving accordingly.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
When this warning light is on, the system will not limit
wheel spin. Adjust your driving accordingly.

2-84
Engine Coolant Temperature Gage
United States Canada
Your vehicle has a gage that shows the engine coolant
temperature. If the gage pointer moves into the shaded
area, the engine is too hot.
That reading means the same thing as the warning light.
It means that the engine coolant has overheated. If you
have been operating the vehicle under normal
conditions, you should pull off the road, stop the
vehicle, and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
the system is low on
coolant and the engine
may overheat.
See ªEngine Coolantº in the Index and have the vehicle
serviced as soon as possible.

2-90
Fuel Gage
United States Canada
The fuel gage tells you about how much fuel you have
left when the ignition is on. When the indicator nears
empty, you still have a little fuel left, but you should get
more soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not indicate
a problem with the fuel gage:

At the gas station, the pump shuts off before the gage
reads full.
It takes more (or less) fuel to fill up than the gage
indicates. For example, the gage reads half full, but it
took more (or less) than half the tank's capacity to
fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate full when the ignition is
turned off.
Low Fuel Warning Light
If your fuel is low, the
warning light near the fuel
gage will go on.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working
properly. If it doesn't come on then, see your dealer
for service.

Functions
(Door Ajar): If one of the doors is ajar, this
light will appear next to that door on the vehicle outline.
CHANGE OIL SOON: This light will appear when the
system indicates that it's time for an oil change. The
system predicts remaining oil life using data from length
of drives, coolant temperature, engine rpm and vehicle
speed. It alerts you to change the oil on a schedule
consistent with the vehicle's driving conditions. After
changing the oil, the system must be reset. See ªHow to
Reset the GM Oil Life System
º in the Index.
LOW: This light will come on when the ignition is
on and the fluid in the washer fluid container is low.
AJAR: This light alerts you that the trunk is not
fully closed.LOW TRAC (Low Traction): This light will come on
when the enhanced traction system is limiting wheel
spin. See ªEnhanced Traction Systemº or ªLow Traction
Lightº in the Index.
TRAC OFF (Traction Off): This light lets you know
that the enhanced traction system has been disabled and
will not limit wheel spin. See ªEnhanced Traction
System Warning Lightº or ªLow Traction Lightº in
the Index.
TRAC (Traction): If the vehicle has the enhanced
traction system, you will have a disable button on the far
right side of the DIC. The enhanced traction system is
automatically activated when you turn the ignition on.
This button will activate/deactivate the system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.

2-96
TRAC OFF (Traction Off) or TCS OFF (Traction
Control System Off): This light lets you know that the
enhanced traction system (3100 or 3800 V6 engine) or
the traction control system (3800 supercharged V6
engine) has been disabled and will not limit wheel spin.
See ªTraction Control System Warning Light,º
ªEnhanced Traction System Warning Lightº and ªLow
Traction Lightº in the Index.
TRAC (Traction) or TCS (Traction Control System):
If the vehicle has the enhanced traction system (3100 or
3800 V6 engine) or the traction control system
(3800 supercharged V6 engine), you will have a disable
button on the far right side of the trip computer. The
enhanced traction system and traction control system are
automatically activated when you turn the ignition on.
This button will activate/deactivate the system. If you
need to disable the system, such as when you are stuck
and are rocking the vehicle back and forth, push this
button. See ªStuck: In Sand, Mud, Ice or Snowº in
the Index.Head-Up Display (HUD) (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the Head-Up
Display (HUD), you can
see the speedometer reading
(in English or metric units)
and a brief display of the
current radio station or CD
track, displayed ªthroughº
the windshield.

2-97
When you sit up straight in your seat, the HUD image
will appear straight ahead near the front bumper.
The HUD also shows the following lights when they are
lit on the instrument panel cluster:

Turn Signal Indicators

High
-Beam Indicator Symbol

Low Fuel Symbol
The HUD will display CHECK GAGES when the
following items are lit on the instrument panel cluster:

Oil Warning Symbol

Coolant Temperature Symbol

Charging System Symbol
When the ignition key is turned to RUN, the entire HUD
image will come on. Then the Head
-Up Display will
operate normally.
NOTICE:
Although the HUD image appears to be near
the front of the vehicle, do not use it as a parking
aid. The HUD was not designed for that purpose.
If you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.
When the HUD is on, the speedometer reading will be
displayed continually. The current radio station or CD
track number will only be displayed for three seconds
after the radio or CD track status changes. This will
happen whenever one of the radio controls is pressed,
either on the radio itself or on the optional steering
wheel controls.
