Audi A4: Overview - Rearview Camera System
The rear view camera system (KA2) assists the driver during
back-up driving for diagonal and parallel parking for trailer
towing and watching cross traffic by providing the driver with
an image of the traffic situation behind the vehicle via the
Front Information Display Control Head -J685-.
The rear view camera system is switched on when engaging the
reverse gear. The system can be activated manually by pressing
the Parking Aid Button -E266- in the instrument panel
(optional).
The rear view camera system consists of the following
components:
- Rearview Camera -R189-
- The Rearview Camera System Control Module -J772- is
integrated in the Rearview Camera -R189-
- Information Electronics Control Module 1 -J794-
- Front Information Display Control Head -J685-
Other control modules may be installed as optional
equipment.
It is not permitted to install an auxiliary license plate
for vehicles with rear view camera system as it could impair the
function of the rear view camera system.
