Actuation
In the event that the driver has an emergency in a remote area, a Customer Assistance Center (CAC) technician can use the data received (SMS and a voice connection) from the emergency call system control unit (N123/4) to obtain an overview of the situation in the vehicle interior and then initiate the appropriate emergency measures. A Telematic Alarm Identification on Demand (emergency call system) (TELE AID) emergency call can be initiated automatically or manually.

Manual emergency call
A manual emergency call can be made at any time. A manual emergency call is triggered by actuating the SOS pushbutton switch (S93/3) labeled with "SOS". It is integrated into the overhead control panel control unit (N70).

The SOS pushbutton switch is read in by the emergency call system control unit over a discreet line. To manually trigger an emergency call, the SOS pushbutton switch has to be actuated for more than 0.5 s. The red light emitting diode (LED) in the SOS pushbutton switch flashes on and off for the duration of the emergency call. After this, an emergency call message is sent immediately to the nearest emergency call center.

automatic alarm call
An automatic emergency call is possible after "circuit 15R ON". A vehicle crash is automatically detected by the restraint systems control unit (N2/7). The emergency call system control unit receives the crash information as a digital crash signal from the restraint systems control unit via a discrete line, and additionally (redundantly) via the interior CAN. In the event of an accident, an emergency call is automatically sent out immediately.

An emergency call is sent out regardless of the severity of the accident. In the event of a crash triggering, the red LED in the SOS pushbutton switch flashes on and off for the duration of the emergency call. The user can now get in contact with the emergency call center by telephone. After the conversation is completed, the connection is deactivated by the emergency call center. The emergency call system control unit deactivates the emergency call request both for a manual and an automatic emergency call after several unsuccessful attempts.

It is only permissible to trigger a TELE AID emergency call in case of an emergency; violations are a punishable offense.

Generating an emergency call telegram
In the event of an emergency call, all the data for an emergency call telegram are compiled by the emergency call system control unit. The following data are automatically transmitted as an SMS (not with Advanced Mobile Phone System (AMPS)) in the event of an emergency telegram:
^ Subscriber identification module (SIM) data
^ Phone number
^ Type of deployment (manual or automatic emergency call)
^ Vehicle data (e.g. circuit status)
^ Crash information (severity of accident), only for an automatic emergency call
^ Vehicle position and history
^ Direction of travel and speed

Transmitting an emergency call telegram
In the event of an emergency call, in addition to active telephone connections, active service calls (MB-Info or telediagnosis) are also interrupted. The emergency call system control unit transmits an emergency call telegram to the closest emergency call center and then establishes a telephone connection to the emergency call center. If the emergency call was started automatically and the connection to the emergency call center was not possible, a telephone connection is automatically established to the police emergency phone number "911". In this case, no emergency call data are transmitted. The emergency call data must then be communicated verbally. This process can be configured for manual calls.

The TELE AID must be authorized for transmission of an emergency call telegram.
