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
reservoir.
G
Overfilling the brake fluid reservoir can
result 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 multifunction display.
Read and observe messages in the
multifunction display ( page 376).
Risk of accident! Do not drive any
further. 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.
