!The Tele Aid system utilizes the cellular net-
work 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.
iWhen a Tele Aid call has been initiated, the
audio system or COMAND* system audio is mut-
ed and the selected mode (radio, tape or CD)
pauses. The optional cellular phone* (if installed)
and 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 loca-
tion. Remove the phone from the cradle 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 commands 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. After
the Tele Aid call has ended, the optional cellular
phone switches on again. A PIN entry might be
necessary.
