fic situation. An inappropriate brake applica-
tion may be interrupted at any time if you:
R steer slightly in the opposite direction
R switch on the turn signal
R
clearly brake or accelerate
A lane-correcting brake application is inter-
rupted automatically if:

(60 km/h) and lane markings are detected,
the lines in the assistance graphics display
(

Lane Keeping Assist is ready for use.
If
Standard Standard is selected, no warning vibra-
tion occurs if:
R you have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.
R a driving safety system intervenes, such
as ABS, BAS or ESP ® .
When Adaptive Adaptive is selected, no warning
vibration occurs if:
R you have switched on the turn signals. In
this event, the warnings are suppressed
for a certain period of time.

essary and in good time if you cross the lane
marking, the system recognizes certain con-
ditions and warns you accordingly.

bend.
