If the vehicle is braked sharply from speeds
above 50 km/h, the brake lamps flash rapidly.
This provides traffic travelling behind you with an
even more noticeable warning.
If the vehicle is travelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
the vehicle is stationary. When you pull away
again, the hazard warning lights will switch off
automatically at approximately 10 km/h. You
can also switch off the hazard warning lights
using the hazard warning button.
ATTENTION ASSIST
Function of ATTENTION ASSIST
ATTENTION ASSIST assists you on long, monoto‐
nous journeys, e.g. on motorways and trunk
roads. If indicators of fatigue or increasing lap‐
ses 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-
rested and attentive driver. On long journeys,
take regular breaks in good time that allow for
adequate recuperation.
You can choose between two settings:
Standard: normal system sensitivity.
R
Sensitive: increased system sensitivity: the
R
driver is warned earlier and the attention
level detected by the system is adapted
accordingly.
If drowsiness or increasing lapses in concentra‐
tion are detected, the
ATTENTION ASSIST: Take
a break!
warning appears in the driver display.
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.
