Pontiac 2004 GTO - Manual (Page 126)

Anti-Lock Brake System
Warning Light
To ensure that the warning
light is working, the symbol
is displayed for a short
time when the ignition is
turned to ON.
If the light doesn’t come on then, have it fixed so it will
be ready to warn you if there is a problem.
If there is a malfunction of the anti-lock brake system,
the symbol will illuminate and ABS Fault will appear
on the trip computer display. See your dealer for service.
The car’s brake system will still operate conventionally,
only the anti-lock operation is impaired.
The ABS Fault message will remain until the MODE
button on the trip computer is pressed, but the symbol
will remain until the problem is fixed.
Engine Coolant Temperature Gage
The temperature gage
shows the engine coolant
temperature when the
ignition is on.
If the gage pointer moves into the red area, the light
comes on and you hear a chime, 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.
