user ID and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, and
more.The Tele Aid system
(Tele

D
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
cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the audio system or on the multifunc-
tion steering wheel. To raise, turn the rota-
ry volume control on the audio system
clockwise or press buttonæ on the
multifunction steering wheel. To lower,
turn the rotary volume control on the audio
system control counterclockwise or press
buttonç on the multifunction steering
wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
!The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the ¡button. Failure to complete
either of these steps will result in a system that
is not activated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-800-387-0100 (in Canada).
iThe SOS button is located above the inside
rear view mirror (
page 217).
The Roadside Assistance button•
(
page 217) and the Information button¡
(
page 218) are located in the center storage
compartment.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (
Global Po-
sitioning
System) satellites for vehicle location.
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 is muted and the selected mode
(radio or CD) pauses. The mobile phone (if in-
stalled) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle at a standstill in a safe location. Remove
the phone from the cradle and place the call. The
multifunction display in the instrument cluster is
available for use. After the Tele Aid call has end-
ed, the optional mobile phone switches on again.
