The system can detect decreasing alertness or
fatigue of the driver during long, monotonous
trips, for instance on highways. In this situation, it
is recommended that the driver takes a break.
The system cannot serve as a substitute for the

fatigue may not be detected or not be detected
in time. There is a risk of accident. Make sure
that the driver is rested and alert. Adjust driving

The system is switched on each time drive-ready

This procedure takes the following criteria into
▷ Personal driving style, for instance steering
▷ Driving conditions, for instance time, length of
Starting at approx. 43 mph/70 km/h, the system
