corrective steering intervention is not sufficient to

Lane Keep Assist is automatically deactivated before
or in the bend and no corrective steering interven-
L
tion occurs.

Information
P
The driver's steering behaviour is monitored when
Q
Lane Keep Assist is active. If no more steering ac-
tivity is detected and the vehicle is about to stray
R
from the lane several times, the instrument cluster
S
issues an acoustic and visual warning and prompts
the driver to take over the steering.
T
If the driver does not respond to this, Lane Keep As-
U
sist switches to a passive mode (see status display).
Steering intervention on the part of the driver re-
V
activates Lane Keep Assist.

If Lane Keep Assist must intervene for an extended
period, the instrument cluster issues an acoustic and
X
visual warning and prompts the driver to align the

vehicle in the centre of the lane.
