chirp and voice contact will be interrupted. Voice 
contact will resume once the retransmission is 
completed. Once a call is concluded, a chirp will be 
heard and the appropriate indicator lamp will stop 
flashing. The COMAND system operation will resume 
(only vehicles with COMAND).
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 Customer Assistance at

pressing ìbutton on the multifunction steering 
wheel.
When a Tele Aid call has been initiated, the audio 
system or the COMAND system audio (only vehicles 
with COMAND) is muted and the selected mode (radio, 
tape or CD) pauses. The optional cellular phone (if 
installed) switches off. If you must use this phone, the 
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 
available for use and spoken commands are only 
available by pressing the RPT button on the COMAND

291 Malfunction and indicator lamps
Te ch n i c a l
data Instruments 
and controlsOperation DrivingInstrument 
cluster displayPractical hints Car care Index 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. 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 of f. 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 276 for notes on antilock brake system (ABS).
