The ABS has detected a malfunction
and has switched off.
®
The ESP and the BAS are also
deactivated.
The brake system is still functioning
normally but without the ABS avail-
able.
The ABS was deactivated because of
insufficient power supply. The charg-
ing voltage has fallen below 10 volts.
The brake system is still functioning
normally but without the ABS

Practical hints
Possible solution
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Have the system checked at an authorized
Mercedes-Benz Light Truck Center as soon
as possible.
Failure to follow these instructions increases
the risk of accident.
When the voltage is above this value again, the
ABS is operational again and the message in
the multifunction display should disappear.
If the message in the multifunction display
does not disappear:
Have the generator (alternator) and the
battery checked.
