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 on the side for

If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
If a lane-correcting brake application occurs,
display : appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a solid or broken lane marking.
Before this, a warning must be given by means of
intermittent vibration in the steering wheel. In
addition, a lane with lane markings on both sides
must have been detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom-
ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.

A further lane-correcting brake application
can only occur after your vehicle has returned
