Brake System Warning Light
Your Cadillac’s hydraulic brake system is divided into two parts. If one
part isn’t working, the other part can still work and stop you. For good
braking, though,
you need both parts working well.

brake system inspected right away.

come
on and turn off as you
start the vehicle. If it
doesn’t come on then,
have it fixed
so it will
be ready to warn you
if
there’s a problem.
This light will also come on when you set your parking brake, and 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. If the
light comes on while driving, pull
off the road and stop carefully. You may
-_ notice that the pedal is harder to push. Or, the pedal may go closer to the
floor. It may take longer to stop.
If the light is still on, have the vehicle
towed for service.
