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 electro-hydraulic brake system is still 
functioning normally but without ABS avail-
able. 
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 (
The charging voltage has fallen below 
10 volts and the ABS was switched off.
The battery may not be sufficiently charged.
Switch off electrical consumers that 
are currently not needed, e.g. seat 
heating.
If necessary, have the generator and 
battery checked.
When the voltage is above this value 
again, the ABS is operational again.
