The red brake warning lamp
comes on when the engine is
running and you hear a warn-
ing sound.
Warning!
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake sys-
tem.
Possible cause/consequence
You are driving with the parking brake set.
There is a malfunction in the
electro-hydraulic brake system.
There is insufficient brake fluid in the reser-
voir.

Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!
If you find that the brake fluid in the brake
fluid reservoir has fallen to the minimum mark or
below, have the brake system checked for brake
pad thickness and leaks.
