Useful features
System self-check
Initially, after switching on the ignition,
malfunctions are detected and indicated
(the indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button ¡ stay on longer
than 10 seconds or do not come on). The
message
Tele Aid inoperative appears
in the multifunction display. Emergency calls
An emergency call is initiated auto-
matically following an accident in which
the emergency tensioning devices (ETDs)
or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 231) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting
call
appears in the multifunction display.
When the connection is established, the
message
Call connected appears in the
multifunction display. All information
relevant to the emergency, such as the
location of the vehicle (determined by the
GPS satellite location system), vehicle
model, identification number and color are
generated.
iWhen a Tele Aid call has been initiated,
the COMAND system audio is muted and the
selected mode (radio, CD etc.) pauses.
The optional cellular phone (if installed) inserted
in cradle switches off. If you must use this
phone, we recommend that you use it only with
the vehicle at a standstill in a safe location.
Remove the phone from the cradle and place the
call. The navigation system (if engaged) will con-
tinue 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 system. A pop-up window will appear
in the COMAND system display to indicate that a
Tele Aid call is in progress. After the Tele Aid call
has ended, the optional cellular phone inserted
in the cradle switches on again. A PIN entry
might be necessary.
Warning!G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message
Tele Aid inoperative is displayed in the
multifunction display after the system
self-check, a malfunctio n in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.
