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:

If ATTENTION ASSIST is unable to calculate the
attention level and cannot issue a warning, the
System suspended message appears.
If a warning is given in the Instrument Display, the
multimedia system offers to search for a rest
area. You can select a rest area and start naviga-
tion to this rest area. This function can be activa-
ted and deactivated in the multimedia system.
If ATTENTION ASSIST is deactivated, the Û
symbol appears in the assistance graphic in the
Instrument Display. After the vehicle is started,
ATTENTION ASSIST is automatically activated. The
last selected sensitivity level remains stored.
