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 332) 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 multifunc-
tion display. When the connection is estab-
lished, the message
Call connected
appears in the multifunction display.
All information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), 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
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 system. A pop-up
window will appear in the COMAND system dis-
play 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 malfunction 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.
