chirp will be heard and the appropriate indicator lamp 
will stop flashing. The COMAND system operation will 
resume.
Important!
If the indicator lamp continues to flash or the system 
does not reset, contact the Response Center at 
1-800-756-9018 (in the USA) or 1-888-923-8367 (in 
Canada), or Mercedes-Benz Client Assistance at

vehicle must be parked. Disconnect the coiled cord and 
place the call. The navigation system (if engaged) will 
continue to run. The display in the instrument cluster is

ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the 
instrument cluster comes on with the 
electronic key in starter switch position 2 
and should go out with the engine running.
When the ABS malfunction indicator lamp symbol and 
warning in the instrument cluster remains illuminated 
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.
A malfunctioning ABS control unit can possibly affect 
the operation of other systems (e.g. Parktronic, 
Navigation, Automatic transmission). Be guided 
accordingly with respect to the use of those systems and 
have the system checked at your authorized 
Mercedes-Benz Center as soon as possible.With the ABS malfunctioning, the BAS and ESP are also 
switched off. The malfunction indicator lamps and 
malfunction messages in the multifunction display 
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 Center as soon as possible.
See page 269 for notes on antilock brake system (ABS).
