Brake System Warning and Parking
Brake Indicator Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on
briefly when you turn the
ignition key to ON. If it
does not come on
then, have it fixed so it will
be ready to warn you if
there is a problem.
