The Tele Aid system utilizes the cellular
network for communication and the GPS (Global
Positioning System) satellites for vehicle loca-
tion. If either of these signals are unavailable, the
Tele Aid system may not function and if this
occurs, assistance must be summoned by other
means.
i
When a Tele Aid call has been initiated, the
COMAND system audio is muted and the select-
ed mode (radio, CD etc.) pauses. The optional
cellular phone (if installed) inserted in cradle
switches off. If you must use this phone, we rec-
ommend 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 naviga-
tion* system (if engaged) will continue to run.
The display in the instrument cluster is available
for use, and spoken commands are only avail-
able 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 malfunction in the system has
been detected.
