General
The MB-Info call function enables the customer to call up information on Mercedes-Benz brand products as well as further voice-based services (e.g.
hotel booking). For example, it provides information on the following services:
^
Current traffic conditions
^
Technical questions, complaints and services
^
Mercedes-Benz products and Mercedes Card
^
Leasing and financial offers
This vehicle-related service is primarily an oral information service that is provided via the communications module integrated into the emergency call
system control unit.
The MB-Info call function consists of the two following subfunctions:
^
MB-Info call function sequence
^
Function sequence for display of additional services
MB-Info call function sequence
The MB-Info button is read in directly by the emergency call system control unit via a discrete line.
The emergency call system control unit automatically transmits an SMS with the following data via the integrated communication module to the CAC:
^
Vehicle position
^
Customer identification data
^
Vehicle identification data
Additionally, the communication module integrated into the emergency call system control unit sets up a voice communication to the CAC.
The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the
following way:
^
Discrete line
^
Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada
^
Discrete line
^
Multifunction antenna (A28/11)
The MB-Info button's integrated light emitting diode (LED) flashes as long as the MB-Info call is activated.
In the event of an MB-Info call, other vehicle-related services (e.g. vehicle remote door unlock) and, for vehicles with code (389) Mobile phone
preinstallation with universal interface, USA/Canada, any active mobile phone connections are interrupted.
In the event of a multifunction antenna malfunction (e.g. defective because of rollover) the emergency call system control unit automatically uses the
emergency call system antenna (A2/52) to transmit mobile phone signals or data.
