Pontiac 2005 Grand Prix - Manual (Page 147)

{ 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
have pulled off the road and stopped carefully,
have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
If the vehicle has the
Anti-lock Brake System
(ABS), this light will come
on when the engine is
started and may stay on
for several seconds.
That is normal.
If the ABS warning light comes on and stays on, there
may be a problem with the anti-lock portion of the brake
system. If the brake system warning light is not on,
the vehicle still has brakes, but it does not have anti-lock
brakes. See Brake System Warning Light on page 3-40.
If the light stays on, the vehicle needs service. If the
light comes on while the vehicle is being driven, stop as
soon as possible and turn the ignition off. Then start
the vehicle again to reset the system. If the light
still stays on, or comes on again while driving, the
vehicle needs service. If the regular brake system
warning light is not on, the vehicle still has brakes, but it
does not have anti-lock brakes. If the brake system
warning light is also on, the vehicle does not have
anti-lock brakes and there is a problem with the regular
brakes. See Brake System Warning Light on page 3-40.
If both the brake system warning light and the anti-lock
brake system light is on, pull off the road and have
the vehicle towed for service.
The anti-lock brake system warning light will come on
briefly when the ignition key is turned to RUN. This
is normal. If the light does not come on then, have it
fixed so it will be ready to warn you if there is a problem.
