Pontiac 2005 Grand Prix - Manual (Page 146)

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part
can still work and stop the vehicle. For good braking,
though, both parts should be working well.
This light should come on briefly when the ignition
key is turned to RUN. If it does not come on then,
have it fixed so it will be ready to warn you if there
is a problem.
When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means the vehicle has a brake problem.
The PARKING BRAKE ON message will also appear in
the Driver Information Center (DIC) when the parking
brake is set and the vehicle is going faster than 5 mph.
See DIC Warnings and Messages on page 3-69 for
more information.
The brake warning light may also come on when the
brake fluid is low. If this occurs, the LOW BRAKE FLUID
message will also appear in the Driver Information
Center (DIC). See DIC Warnings and Messages
on page 3-69 for more information.
If the brake warning light comes on while the vehicle
is being driven, pull off the road and stop carefully.
The brake pedal may be harder to push, or it may go
closer to the floor. It may also take the vehicle longer to
stop. If the light is still on, have the vehicle towed for
service. See Towing Your Vehicle on page 4-38.
