The Tele Aid system

(Telematic Alarm Identification on
Demand)

The Tele Aid system consists of three
types of response:

앫

automatic and manual emergency

앫

roadside assistance and

앫

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 using the volume control on
the MCS unit.

왘

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 ac-
quaintance call, you will receive a user ID
and password via first call mail. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, profile
and more.

System self-check

Initially, after turning the key in the steer-
ing lock to position 2, malfunctions are de-
tected and indicated (the indicator lamps
in the SOS button, the Roadside Assis-
tance button

• and the Information

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 summoned
by other means.

Emergency calls

An emergency call is initiated automatical-
ly:

앫

following an accident in which the
emergency tensioning detractors
(ETDs) or airbags deploy,

앫

if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (

briefly pressing the button located under
the cover. See below for instructions on
initiating an emergency call manually.

Warning!

G

The Tele Aid control unit is located under
the front passenger seat. If there is accumu-
lation of water or other liquid in this area,
the Tele Aid control unit could suffer an
electrical short circuit making the system in-
operative. In this case the indicator lamp in
the SOS button will not illuminate during or
will remain illuminated after the system
self-check. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button do not come on dur-
ing the system self-check or if any of these
indicators remain illuminated constantly in
red and/or the message TELE AID -
VISIT WORKSHOP is displayed in the MCS
display after the system self-check, a mal-
function in the system has been detected.

If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message

EMERGENCY CALL –

CONNECTING CALL

appears in the MCS dis-

play. When the connection is established,
the message

CALL CONNECTED

appears in the MCS dis-

play. All information relevant to the emer-
gency, such as the location of the vehicle
(determined by the GPS satellite location
system), vehicle model, identification num-
ber and color are generated.

A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
When a voice connection is established the
audio system mutes and the message

pears in the MCS display. The Response
Center will attempt to determine more pre-
cisely the nature of the accident provided
they can speak to an occupant of the vehi-
cle.

The Tele Aid system is available if:

앫

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

앫

the relevant cellular phone network
and GPS signals are available and pass
the information on to the response cen-
ter.

i

Location of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network
and pass the information on to the re-
sponse center.

Warning!

G

If the indicator lamp in the SOS button is il-
luminated continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant cellular phone network is not available).
The message EMERGENCY CALL –
CALL FAILED appears in the MCS display
for approx. ten seconds.

Should this occur, assistance must be sum-
moned by other means.
