Emergency call actuation, function

A TELE AID emergency call can be triggered automatically or manually:

Manually:

 With the aid of the SOS pushbutton switch (S93/3s1), if the vehicle is not involved itself in an accident or the driver requires help.

 with the aid of the emergency alarm actuation switch (S62/6) (only with code 930, taxi emergency call).

For diagnostic purposes, manually with Star Diagnosis.

Automatically:

 via the restraint system control unit (N2/7) when an airbag/sidebag is actuated or in the event of severe rear-end collision.

-----------------------------------------------------------------------------------------

 When the external tilting cone sensor (B66) recognizes a rollover and transmits it to the D2B telephone and TELE AID transmitter/receiver (A35/17) or

 if the rollover sensor in the TELE AID control unit (A35/8) (models 208, 210, 215, 220) registers a rollover.

A TELE AID emergency call is completed when the service center terminates the voice connection.

Peculiarities on taxi emergency call (only with code 930)

A taxi emergency call should not be noticed by the person(s) posing the threat. For this purpose the emergency alarm actuation button (S62/6) is concealed in the driver's footwell. An indicator lamp, which confirms that the emergency alarm system activate button (S62/6) has been pressed, may be installed as an option. It illuminates for 2 minutes after a taxi emergency call is triggered. The indicator lamp is installed so that only the driver can recognize when it flashes. Moreover, it is ensured that in the event of a taxi emergency call:

 When no dial or ring tone can be heard,

 the dialing procedure is carried out silently,

 the status indicator is not activated in the SOS pushbutton switch (S93/3)

 the volume of the radio cannot be decreased or the radio cannot be set to mute.

 no confirmation messages can be received from the service provider or the police.

-----------------------------------------------------------------------------------------

The police monitors the passenger compartment via the hands-free system on a taxi emergency call and decides if a voice connection should be completed.

The taxi emergency call can be terminated:

 by the police

 automatically by the D2B telephone and TELE AID transmitter/receiver (A35/17) after approximately
90 minutes

 when an automatic TELE AID emergency call is triggered.

 A TELE AID emergency call or taxi emergency call can only be triggered in emergencies. The telephone system cannot be used during an emergency call.
