Possible cause
You are driving with the parking brake set.
There is a malfunction in the SBC brake
system.
There is insufficient brake fluid in the res-
ervoir.
G
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.
Suggested solution
Release the parking brake.
Observe the additional message in
the display.
Risk of accident! Do not drive any fur-
ther. Consult a Mercedes-Benz
Service Center. Under no circum-
stances should you top up the brake
fluid. This will not solve the problem.
!
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.
