ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the 
instrument cluster comes on with the key in 
steering lock position 2 and should go out 
with the engine running.
When the ABS malfunction indicator lamp in the 
instrument cluster comes on while the engine is 
running, it indicates that the ABS has detected a 
malfunction and has switched off. In this case, the brake 
system functions in the usual manner, but without 
antilock assistance.
With the ABS malfunctioning, the BAS, ESP and 4-ETS+ 
are also switched off. Both malfunction indicator lamps 
come on with the engine running.
If the charging voltage falls below 10 volts, the 
malfunction indicator lamp comes on and the ABS is 
switched off. When the voltage is above this value again, 
the malfunction indicator lamp should go out and the 
ABS is operational.
Have the system checked at your authorized 
Mercedes-Benz Light Truck Center as soon as possible.
See page 201 for notes on antilock brake system (ABS).Adjustable steering wheel – indicator lamp
