The yellow ABS indicator lamp
comes on while driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP are also
switched off (see messages in display).
The SBC brake system is still functioning nor-
mally but without ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as Parktronic*, Distronic*,
or the automatic transmission may also be
malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
Read and observe messages in the
display (

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.
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.
