ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST can assist you on long,
monotonous journeys, e.g. on motorways and
trunk roads. If ATTENTION ASSIST detects indica‐
tors of fatigue or increased lapses in concentra‐
tion 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.
You can choose between two settings:
Standard: normal system sensitivity
R
Sensitive: higher system sensitivity. The
R
driver is warned earlier and the attention level
detected by the system (Attention Level) is
adapted accordingly.
If fatigue or increased lapses in concentration are
detected, the ATTENTION ASSIST: Take a break!
warning appears in the Instrument Display. You
can acknowledge the message and take a break if
necessary. If you do not take a break and ATTEN‐
TION ASSIST continues to detect increased lap‐
ses in concentration, you will be warned again
after a minimum of 15 minutes.

If ATTENTION ASSIST cannot calculate the atten‐
tion level and cannot issue a warning, the
tion level message appears.
If a warning is displayed 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 é
symbol appears in the assistance graphic in the
instrument display when the engine is running.
ATTENTION ASSIST is activated automatically
when the engine is re-started. The last selected
sensitivity level remains stored.
