- with CODE (359) TELE AID emergency call system

Actuation
Misuse of an emergency call alarm is subject to punishment.

The emergency call system must be authorized.

The emergency call system is activated using two different methods:
^ automatically in the event of an accident, rollover or airbag actuation
^ manually by actuating the SOS pushbutton switch (S93/3) in the overhead control panel control unit (N70)
In both cases, an emergency call message (SMS) is transferred to the closest emergency call center immediately.

Automatic emergency call
The automatic emergency call is actuated by the restraint system control unit (N2/7). An emergency call is sent out regardless of the severity of the accident. For this purpose, a discreet digital crash signal containing the accident information is sent to the emergency call system control unit by the restrain system control unit.
Simultaneously, redundant crash information is transferred to the emergency call system control unit over the Control Area Network bus class C (engine compartment) (CAN C), the central gateway control unit (N93) and the Control Area Network bus class D (diagnosis) (CAN D). The crash information reports on the type of accident (head-on, rear end, side or rollover accident).

Manual emergency call
The manual emergency call is actuated by pressing the SOS pushbutton switch integrated into the overhead control panel control unit. It is connected discreetly to the emergency call system control unit and must be pressed for longer than 0.5 s. When a manual emergency call is sent, the red LED in the SOS pushbutton switch flashes.

In the event of an emergency call, in addition to active telephone connections, active service calls (MB-Info, roadside assistance call) are also interrupted.

Data automatically transferred with an emergency call include:
^ Phone number
^ Vehicle data (accident data and circuit status)
^ Position data
^ Direction of travel and speed

The emergency call data are sent to the next closest emergency call center by the emergency call system control unit.
Simultaneously, a telephone connection to the emergency call center is completed in parallel.

If automatic connection to the emergency call center is not possible, a telephone connection to the emergency call number "911" is automatically completed. In this case, no emergency call data are transmitted. The emergency call must then be made verbally. In the event of a manual emergency call, this process can be configured by the user.

Emergency calls are terminated
^ normally by the emergency call center or
^ by the emergency call system control unit after five unsuccessful dialing attempts.
