WARNING Risk of accident despite
Active Lane Keeping Assist warning
A lane-correcting brake application cannot
always bring the vehicle back into the origi‐
nal lane.

WARNING Risk of accident despite inter‐
vention of Active Lane Keeping Assist

driving over a solid lane marking.
The brake application can be interrupted at
any time if you steer slightly in the opposite
direction.
#
Always make sure that there is suffi‐
cient distance to the side for other traf‐
fic or obstacles.
&

not give a warning

Always pay particular attention to the
traffic situation and keep within the
lane, especially if Active Lane Keeping
Assist alerts you.
Be sure to observe the system limitations of
