Useful features
Upgrade signals
The Tele Aid system processes calls using 
the following priority:
Automatic emergency – First priority
Manual emergency – Second priority
Roadside assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated 
while you are connected, an upgrade 
(alternating) tone will be heard, and the 
appropriate indicator lamp will flash. If 
certain information such as vehicle identi-
fication number or customer information is 
not available, the operator may need to 
retransmit.
During this time you will hear a beep and 
voice contact will be interrupted. Voice 
contact will resume once the retrans-
mission is completed. Once a call is 
concluded, a beep will be heard and the 
respective indicator lamp will stop flash-
ing. The COMAND* system operation will 
resume.
!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 1-800-FOR-MERCedes 
(1-800-367-6372) in the USA or 
Customer Service at 1-800-387-0100 
in Canada.iThe indicator lamp in the respective 
button flashes until the call is con-
cluded. Calls can only be terminated by 
a Response Center or Customer Assis-
tance Center representative except 
Roadside Assistance and Information 
calls, which can also be terminated by 
pressing buttonì on the multifunc-
tion steering wheel.
iWhen a Tele Aid call has been initiated, 
the audio system or the COMAND* sys-
tem audio 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. Dis-
connect the coiled cord and place the 
call. The COMAND* navigation system 
(if engaged) will continue to run. The 
display in the instrument cluster is 
available for use, and spoken com-
mands are only available by pressing 
the RPT button on the COMAND* unit. 
A pop-up window will appear in the 
COMAND* display to indicate that a 
Tele Aid call is in progress.

service indicator yourself.

tion display:SERVICE INTERVAL?
RESET WITH R BUTTON FOR 3 SEC.
To confirm, press reset button until you 
hear a signal.
The service indicator now displays the 
reset interval.
iIf the battery is disconnected, the days 
of disconnection will not be included in 
the count shown by the service indica-
tor. To arrive at the true service 
deadline, you will need to subtract 
these days from the days shown in the 
service indicator.
Do not confuse the service indicator 
with the engine oil level indicator:.
iIf the service indicator was 
inadvertently reset, have a 
Mercedes-Benz Center correct it.
Only reset if the proper service has 
been performed. Resetting the system 
without performing proper service as 
called for by the FSS will cause the FSS 
to incorrectly determine the next 
service interval which will result in 
engine damage not covered by the 
Mercedes-Benz Limited Warranty.
