Camera-based driver support systems (KAFAS): Notes

Depending on the options fitted, various camera-based systems are available. Technically, the system is implemented with a joint camera and a joint control unit, the KAFAS control unit. The functions of the camera-based driver support systems are:

• Lane departure warning
• High-Beam Assistant (not permitted in Japan)
• Road sign recognition Speed Limit Info)

If the customer exclusively orders the High-Beam Assistant (5AC), the system is implemented with its own camera and its own control unit in the inside mirror.

The lane departure warning and high-beam assistant are known systems. The road sign recognition is only  possible with the Professional navigation system.
