emand)
The Tele Aid system consists of three
types of response:

Automatic and manual emergency

Roadside Assistance

Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç or use the volume knob
on your audio system or COMAND* head
unit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
iThe SOS button is located in the overhead
control panel.
The Roadside Assistance button•
(
page 265) and the Information button¡
(
page 267) are located below the center
armrest cover.
!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.
