- with CODE (359) TELE AID emergency call system


Function requirements
^ Status "circuit 30 ON" or "circuit 15R ON"
^ Telematic Alarm Identification on Demand (emergency call system) (TELE AID) system authorized and operating errorfree

Self-test
Following activation of status "circuit 15R ON" the emergency call system control unit performs a self-test (approx. t = 3.5 s). If the self-test is successful, the TELE AID system is operational.

In the event of a fault or if authorization has not been provided, an error message will be displayed in the instrument cluster (A1) depending on the fault type and the two red light emitting diodes (LED) in the emergency call system button (S93/3) are also permanently actuated. Depending on the fault type, the fault is also stored in the emergency call system control unit's memory.

General
The emergency call system control unit enables the following vehicle-related services to be realized:
^ Authorization (Provisioning)

^ MB-Info call
^ Breakdown assistance (Roadside Assistance)
^ Vehicle tracking

^ Telephone antenna selection

Prioritization supplementary information
All listed vehicle-related services run automatically in the emergency call system control unit. The emergency call system control unit has a priority management feature to ensure that it does not have to manage several vehicle-related services at the same time. This determines the point at which a vehicle-related service is to be activated and which vehicle-related service has a higher priority.

Depending on which vehicle-related service is to be activated, the emergency call system control unit releases resources in accordance with the priority list and activates the vehicle-related service or refuses activation because a vehicle-related service with a higher priority is already active. The highest priority is given to the completion of an automatic TELE AID emergency call.
