Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
G
WARNING
Active Lane Keeping Assist only detects traf-
fic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application, e.g.
after intentionally driving over a solid lane
marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance to the side for
other traffic or obstacles.
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is intended to help you return the
vehicle to the original lane.
If a lane-correcting brake application occurs,
display : appears in the multifunction dis-
play.
A lane-correcting brake application can be
made after driving over a lane marking rec-
ognised as being solid or broken. Before this,
a warning must have been issued by means
of intermittent vibration through the steering
wheel. In addition, a lane with lane markings
on both sides must be recognised.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detec-
ted in the adjacent lane. The following vehi-
cles can have an influence on brake applica-
tion: oncoming traffic, vehicles that are over-
taking and vehicles that are driving parallel to
your vehicle.
i A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
No lane-correcting brake application occurs
if:
you clearly and actively steer, brake or
R
accelerate.
you cut the corner on a sharp bend.
R
you have adopted a sporty driving style with
R
high cornering speeds or high rates of

There is a possibility that the Active Lane
Assistant could misjudge the given traffic sit-
uation. An inappropriate brake application
may be interrupted at any time if:
you steer slightly in the opposite direction.
R
you switch on the turn signal.
R
you clearly brake or accelerate.
