- with CODE (359) TELE AID emergency call system

The operating description is comprised as follows:
^ Manual emergency call (E-Call)
^ Automatic emergency call (E-Call)
^ Vehicle tracking
^ Breakdown assistance (Roadside Assistance)
^ MB-Info call
^ Vehicle remote door unlock
^ Vehicle remote door lock

Manual emergency call
A manual emergency call can be accomplished by pressing the emergency call system button (S93/3), denoted by the letters "SOS", integrated into the overhead control panel control unit (N70). The emergency call system button is covered up with a locking flap. Pressing the protective lid unlocks the lid, and it automatically opens with the aid of a spring mechanism. The actual emergency call system button is designed as a normally closed contact.
When the emergency call system button is pressed for at least t = 0.5 s, the emergency call system is activated. When a manual emergency call is initiated, the red light emitting diode in the emergency call system button flashes for the time the manual emergency call is effective. This is also indicated in the instrument cluster (A1) and on the Audio/COMAND display (A40/8).

automatic alarm call
A vehicle crash is detected by the supplemental restraint system control unit (N2/10). The emergency call system control unit (N123/4) receives this crash information (crash event) as a digital crash signal from the supplemental restraint system control unit over a direct line and redundantly over the following path:
- Chassis CAN (CAN E)
- Front SAM control unit with fuse and relay module (N10/1)
- Diagnostic CAN (CAN D)

In the event of a crash signal, an emergency call is automatically sent out immediately. The severity of the crash detected does not play a part. Following crash deployment, the red light emitting diode in the emergency call system button starts to flash and keeps doing so for as long as the emergency call lasts. This is also indicated in the instrument cluster and on the Audio/COMAND display.
The crash level is also sent over the Controller Area Network (data bus/CAN bus) (CAN) to the emergency call system control unit.

Vehicle tracking
After triggering (e.g. due to theft message from customer by telephone), the vehicle position and vehicle condition data is transferred to the Service Center by mobile telephone. From there, the data is relayed to the police or security services.
The position is transferred cyclically or on the basis of various events:
- When a specific distance is exceeded
- Recognition of damage or manipulation to vehicle
- Status "Circuit 15 ON" or "Circuit 15 OFF" (ignition switched on or off)

Roadside assistance
The breakdown assistance button (S93/6s2) is integrated into the overhead control panel control unit. A breakdown assistance call is triggered by the breakdown assistance button. For this purpose, it is necessary to press the breakdown assistance button for t > 0.5 s. Activation is indicated by the LED in the breakdown assistance button flashing. This is also indicated in the instrument cluster and on the Audio/COMAND display.
When the breakdown assistance button is pressed, data (vehicle identification number (VIN), vehicle model, etc.) is automatically sent to the Service Center.
Detailed circumstances and other service requirements can then be discussed between the driver and the Service Center over the still existing voice connection. If required, the Service Center informs the Mercedes-Benz field organization, which then takes suitable action.

MB information call
The MB-Info button (S93/6s1) is integrated into the overhead control panel control unit. Pressing the MB-Info button for t > 0.5 s triggers activation of the MB information service; this is indicated by the LED in the MB Info button flashing on and off. This is also indicated in the instrument cluster and on the Audio/ COMAND display.
When the MB-Info button is pressed, data (vehicle data (VIN, vehicle model, etc.) is automatically sent to the Service Center. The customer request can then be processed over the still existing voice connection.

Vehicle remote unlocking
If the driver has locked himself out (transmitter key (A8/1) locked in vehicle or lost), he can report to the Service Center, identify himself and request remote door unlocking of the vehicle. The driver and the Service Center agree on a time period, for which the trunk lid external operation switch (S88/8) (model 212.0) or liftgate external operation switch (S88/8) (model 212.2) has to be operated. The external operation switch has to be pressed for at least t = 15 s within this time period. The vehicle notifies the relevant Service Center of this using the cellular telephone system. At the same time, a message appears in the instrument cluster indicating to the driver that the service is being performed. The Service Center checks whether a simultaneous request from the driver is present. At the same time, a message appears in the instrument cluster indicating to the driver that the service is being performed. The red light-emitting diode in the emergency call system button also flashes.

If plausibility is checked and found to be successful, a request is sent over mobile radio from the Service Center to unlock the vehicle.

If "Vehicle remote door unlock" is refused by the Service Center because, for example, the external operation switch was not actuated at the time agreed on or legitimization was incorrect, the vehicle remote door unlock function is disabled for t = 15 min.

Vehicle remote locking
The driver notifies the Service Center, legitimizes himself/herself and requests remote door locking of the vehicle. The system receives the command and checks whether it can be performed. The system then sends feedback to the Service Center as to whether the request can be implemented or not. The Service Center then informs the driver of the result.
