If the vehicle is braked sharply from speeds above
50 km/h, the brake lamps flash rapidly. This pro-
vides traffic travelling behind you with an even
more noticeable warning.
ATTENTION ASSIST
▌Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto-
nous journeys, e.g. on motorways and trunk
roads. If ATTENTION ASSIST detects indicators of
fatigue or increasing lapses in concentration on
the part of the driver, it 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:
Standard: normal system sensitivity.
R
Sensitive: higher system sensitivity. The driver
R
is warned earlier and the attention level detec-
ted by ATTENTION ASSIST is adapted accord-
ingly.
If drowsiness or increasing lapses in concentra-
tion are detected, the
ATTENTION ASSIST: Take
a break!
warning appears in the Instrument Dis-
play. You can acknowledge the message and take
a break where necessary. If you do not take a
break and ATTENTION ASSIST continues to detect
increasing lapses in concentration, you will be
warned again after a minimum of 15 minutes.
You can have the following status information for
ATTENTION ASSIST displayed in the assistance
menu of the on-board computer:
The length of the journey since the last break.
