ISIS Emergency Call Function: Notes

Two different emergency calls are possible by telephone. An automatic emergency call triggered by the SIM, which has detected a corresponding crash severity, as well as a manually triggered emergency call via the emergency (SOS) call button.

To place an emergency call by telephone, the telephone and the telephone interface, including antenna system, must be on standby and supplied with sufficient power.

After triggering of the emergency call, an SMS message (Short Message Service: info such as vehicle location, how many airbags were deployed and what speed the crash occured at) is sent to the service provider and a voice connection is set up.

Two numbers are set for the two emergency call functions; these are dialled alternately until a connection is set up. If no connection has been set up after 60 seconds, the telephone dials the emergency number 911.

To support any recovery activity that might be necessary, the Light Module switches on the interior lighting and the hazard warning lights.

The central locking system is also unlocked by the CAS (Car Access System).
