Manual or automatic emergency call, general
If the driver finds himself/herself in an emergency situation in a remote location, a service center employee can obtain an overview of the situation inside the vehicle with the aid of the data received from the emergency call system control unit (voice connection and SMS) and initiate the appropriate action required for help. An emergency call be triggered manually or automatically. The purposes of these emergencies calls are as follows:
- Automatic alerting of the rescue services after an accident
- Alerting of rescue workers at the press of a button (own emergency situation, observed accident)
- Reduction in rescue times through fast emergency notification with details on exact location involved

The emergency call function consists of the following subfunctions:
^ Function sequence for initiating manual emergency call
^ Function sequence for initiating automatic emergency call
^ Function sequence for transmission of emergency call data and communication with the service center

Function requirements for initiating manual emergency call
^ Circuit 30g
^ Triggering of a manual emergency call by pressing the emergency call button (S93/3) for t > 0.5 s
^ A higher-priority vehicle-related service is not active

Function sequence for initiating manual emergency call
The emergency call system control unit directly reads in the emergency call system button via a direct line.

Function requirements for initiating automatic emergency call
^ C. 15R On
^ Triggering of an automatic emergency call by the crash signal and receiving the "crash level" from the supplemental restraint system control unit

Function sequence for initiating automatic emergency call
The emergency call system control unit receives the crash signal from the supplemental restraint system control unit via a direct line. Simultaneously, the emergency call system control unit receives the crash signal (redundant) and the crash level from the supplemental restraint system control unit via the following route:
- Chassis CAN (CAN E)
- Front SAM control unit with fuse and relay module (N10/1)
- Diagnostic CAN (CAN D)

Function sequence for transmission of emergency call data and communication with the service center
After a manual or automatic emergency call has been triggered, the emergency call system control unit completes a voice connection to the service center.
After the service center replies with a special tone, the emergency call system control unit automatically sends an SMS with the following data to the service center via the integrated communication module:
- Vehicle position, direction of travel and history
- Vehicle data and crash analysis (accident severity)

The communication module integrated in the emergency call system control unit transmits and receives the mobile phone signals via the following route:
- Direct line
- Multifunction antenna (A28/11)

If connection to the service center cannot be established when an automatic emergency call is triggered, a voice connection is automatically set up using the emergency number "911" and it is then necessary to communicate the listed data verbally.

If a manual or automatic emergency call is active, this is indicated by one of the two red light-emitting diodes integrated in the emergency call system button flashing. This is also indicated in the instrument cluster (A1) and on the Audio/COMAND display (A40/8).

In the event of a manual or automatic emergency call, other vehicle-related services (e.g. MB Info call) are interrupted.

In the event of a multifunction antenna failure (e.g. defective because of rollover) the emergency call system control unit automatically uses the emergency call system antenna (A2/52) to transmit the mobile phone signals.
