TTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on motorways and trunk
roads. If indicators of fatigue or increasing lapses
in concentration on the part of the driver are
detected, the system suggests taking a break.
ATTENTION ASSIST is only an aid. It cannot
always detect fatigue or lapses in concentration in
time. The system is not a substitute for a well-res-
ted and attentive driver. On long journeys, take
regular breaks in good time that allow for ade-
quate recuperation.
You can choose between two settings:
St Standar
andard: d: normal system sensitivity.
R
Sensitive: e: higher system sensitivity. The driver

tion are detected, the
