ATTENTION ASSIST can assist you on long, monotonous journeys, e.g. on motorways and trunk roads. If ATTENTION ASSIST detects indicators of fatigue or increased lapses in concentration on the part of the driver, it suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot always detect drowsiness or increased lapses in concentration in good time. The system is not a substitute for a well-rested and attentive driver. On long journeys, take regular and timely breaks that allow you to rest properly.
If fatigue or increased lapses in concentration are detected, the ATTENTION ASSIST: Take a break! warning appears in the instrument cluster.
You can acknowledge the message and take a break if necessary. If you do not take a break and ATTENTION ASSIST continues to detect increased lapses in concentration, you will be warned again after a minimum of 15 minutes.
You can have the current ATTENTION ASSIST assessment displayed using the Assistance graphic menu in the on-board computer More.
the journey length since the last break
the attention level determined by ATTENTION ASSIST:
the fuller the bar is, the higher the detected attention level is
the bar empties as attentiveness decreases
If ATTENTION ASSIST cannot calculate the attention level and cannot issue a warning, the System suspended message appears.
The bar display is then dimmed. This is the case, for example, if you are predominantly driving at a speed below 60 km/h or above 200 km/h.
ATTENTION ASSIST is active in the 60 km/h to 200 km/h speed range.
