Self Study Program 637 – Audi Q7 (type 4M) Occupant protection and infotainment

VAG SSP 637. This self study programme describes the occupant protection and infotainment systems of the Audi Q7 (type 4M).

Passive safety

A new airbag control unit J234 was developed for occupant protection in the Audi Q7 (type 4M). It contains a sensor which measures rotation about the Z axis. In addition, the airbag control unit J234 now communicates via the FlexRay bus with other control units such as the ABS control unit J104. The ABS control unit J104 thus receives in real time data on rotation about the Z axis which is utilised by the Electronic Stability Control (ESC) system. Depending on country and trim level, pyrotechnic seat belt tensioners can be installed in the 3rd seat row of the Audi Q7 as an option.

Active safety

Depending on country, 4 Audi pre sense functions are optional for the Audi Q7. In additional to Audi pre sense basic, these are:

  • pre sense rear
  • pre sense front
  • pre sense city

Audi pre sense city is able to warn the driver about vehicles and pedestrians and brake within system limitations. Audi pre sense front brings to the Audi Q7 new functions such as evasion assist and turn assist.


Audi offers various levels of the infotainment modules for the Audi Q7. MMI Radio plus is standard in Germany. This offers interfaces for external devices such as mobile phones or memory cards. The Audi sound system delivers excellent sound quality from its ten speakers. It is controlled using the MMI terminal on the center tunnel.

MMI navigation plus also includes the module Audi connect, which connects the Audi Q7 to the Internet via the LTE standard. Rear passengers can surf via the WiFi hotspot with download speeds of up to 100 Mbit/s and send and receive e-mail. The driver can use the customised Audi connect services ranging from online traffic information to navigation with Google Earth and Google Street View to online media streaming.
