MODELS 230 up to 31.5.04 with CODE (855) TELE AID 

After a TELE AID telediagnosis has been triggered, the D2B telephone and TELE AID transmitter/receiver (A35/17) generates an emergency call telegram and then relays it to the Mercedes-Benz Customer Assistance Center (CAC) via mobile telephone (digital network). Then a radio connection (voice connection) is completed to the vehicle.

In the case of an emergency the D2B telephone and TELE AID transmitter/receiver (A35/17) take over the sole control of the telephone system to ensure the following:

• If the telephone had been switched off before the actuation, it must be activated
• An existing telephone connection is interrupted.

The radio link is established through the telephone system with the aid of the CTEL antenna (A2/22).

If the CTEL antenna (A2/22) is no longer operational because of an accident, the CTEL and TELE AID transmitter/receiver, D2B (A35/17) switches automatically over to the TELE AID backup antenna (A2/50). If the power supply is interrupted (for example battery interruption) the D2B telephone and TELE AID transmitter/receiver (A35/17) switches automatically over to the additional battery (G1/1).

The Mercedes-Benz Customer Assistance Center (CAC) has a graphic-capable workstation with street data base. There the information from he emergency call telegram serve for determining the vehicle location and the vehicle status and the required steps to be taken can be clarified with the Mercedes-Benz experts by telephone.

The emergency call system must be authorized to transmit an emergency call telegram.
