road surface, it warns you that you may be leav-
ing your lane unintentionally.
Lane Keeping Assist is ready to issue warnings:
R
above approximately 60 km/h
R
when the lane markings appear in white in the
on-board computer
When you drive over the lane marking uninten-
tionally:
R
the relevant lane marking is shown in red in
the on-board computer
R
the volume of the audio equipment and/or
hands-free system is reduced and a warning
tone sounds from the loudspeaker on the cor-
responding side of the vehicle
If the vehicle is not fully within the lane markings
after a warning has been issued, no further
warnings are possible.
Lane Keeping Assist does not issue a warning if:
R
you have switched on the turn signals
R
you clearly and actively steer, brake or accel-
erate
R
a driving safety system intervenes, e.g. Active
Brake Assist, Stability Control Assist or the
distance control assistant
The warnings are then suppressed for a certain
time period.
Lane Keeping Assist will warn you when chang-
ing lane if a turn signal has been switched on for
more than 1 minute.

is automatically activated.

puter.
Attention Assist
Important safety notes
ATTENTION ASSIST is only an aid. ATTENTION
ASSIST cannot always detect fatigue or lapses in
concentration reliably or in time. ATTENTION
ASSIST is not a substitute for a well-rested and
attentive driver.
ATTENTION ASSIST may be impaired or inoper-
ative:
R
if there is low visibility, e.g. due to insufficient
road illumination or due to snow, rain, fog or
heavy spray
R
if the windscreen is dirty in the area of the
camera, misted up, damaged or covered, e.g.
by a sticker
R
if no lane markings or several ambiguous lane
markings are present for a lane, e.g. near con-
struction sites
R
if the lane markings are worn, dark or cov-
ered, for example by dirt or snow
R
if there is glare, e.g. due to oncoming traffic,
direct sunlight or reflections (e.g. from wet
road surfaces)
R
on winding roads
R
the distance to the vehicle in front is too small
and the lane markings thus can often not be
detected
R
if attachments, e.g. a snow plough, restrict
the camera's view of the road lane markings
R
after a significant change in load with the igni-
tion switched on. Therefore, start the engine
again after a significant change in load for
ATTENTION ASSIST to be available without
any restrictions.
Make sure that the windscreen is always kept
clean and unobstructed in the area of the cam-
page 352). You can switch on the wind-
screen wiper to clean the windscreen, for exam-
ple, or you can remove snow and ice from the
windscreen.
Overview
ATTENTION ASSIST assists you during long,
monotonous journeys, such as on motorways
and trunk roads. ATTENTION ASSIST is active at
speeds above approximately 60 km/h.
If ATTENTION ASSIST detects typical indicators
of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
break. A warning is shown by ATTENTION
ASSIST irrespective of legally prescribed driving
and rest periods or digital tachograph functions.
