General description
The telematics system combines traffic information, service call and emergency call.
The telematics control unit also always includes a mobile phone.
If necessary, an emergency call or breakdown call can be made via a telematics service centre. With Telematics II, it is also possible to call up current traffic information.
The telematics control unit determines the exact position of the vehicle using GPS data and this is also transmitted to the telematics service centre.
An emergency call is made automatically if the airbag control unit triggers a crash signal.
