CAUTION:
{
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
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 fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
