parking brake, and it 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.
Anti4 ock Brake System Warning Light
ANTI-
LOCK
With the anti-lock brake system, this light will come on when you start your
engine and may stay on for several seconds. That’s normal.
If the light
doesn’t come on, have
it fixed so it will be ready to warn you if there is a
problem.
If the light stays on, or comes on when you’re driving, your vehicle needs
service.
If the regular brake system warning light isn’t on, you still have
brakes, but
you don’t have anti-lock brakes. If the regular brake system
warning light
is also on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier
in this part.
