Lane-correcting brake application
G WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake
application.
G WARNING
Active Lane Keeping Assist only detects
traffic 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 on the side for
other traffic or obstacles.
If you leave your lane, under certain
circumstances 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 lane marking
recognize as being solid or broken. 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 be recognized.
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: oncoming traffic, vehicles that
are overtaking and vehicles that are driving
parallel to your vehicle.
i A further lane-correcting brake
application can only occur after your
vehicle has returned to the original lane.
