Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-
mitter operation instructions regarding use
of an external antenna.
iThe electrical outlet can be used to
accommodate electrical consumers
(e.g. air pump, auxiliary lamps) up to a
maximum of 180 W.
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or serious
personal injury.

Tele Aid*
Warning!
G
Please do not forget that your primary
responsibility is to drive the vehicle. A
driver’s attention to the road must always be
his /her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe loca-
tion and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
cellular telephone while driving a vehicle.
Only operate the COMAND* (Cockpit Man-
agement and Data System) and audio sys-
tem if road, weather and traffic conditions
permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
1Observe all legal requirements.
!The initial activation of the Tele Aid
system may only be performed by
completing the subscriber 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 ac-
tivation, please call the Response Cen-
ter at 1-800-756-9018 (in the USA) or

The Tele Aid system consists of three
types of response:


automatic and manual emergency


roadside assistance and


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 multifunction steering wheel. To
raise, press button æ and to lower,
press button ç. The volume can also
be adjusted using 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. Shortly after the completion of your Tele
Aid acquaintance call, you will receive a
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.
System self-check
Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button
• and the
Information button ¡ stay on longer
than ten seconds or do not come on). The
message
Tele Aid malfunction. Drive
to workshop
appears for approximately
ten seconds in the multifunction display.
iThe SOS button is located above the in-
side rear view mirror.
The Roadside Assistance button •
and the Information button ¡ are

cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency 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 264) for instruc-
tions on initiating an emergency call man-
ually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting call

appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
Call connected
appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the
vehicle (determined by the GPS satellite
location system), vehicle model, identifica-
tion number and color are generated. A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon
after the emergency call has been initiat-
ed. The Response Center will attempt to
determine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:


it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time


the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center

nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only
possible if the vehicle is able to receive
