Lane-correcting brake application
If you leave your lane under certain circum-
stances, the vehicle will brake briefly on one
side. This is designed to help you bring the
vehicle back into the original lane.
This function is available in the range between
60 km/h and 200 km/h.
A lane-correcting brake application can only
be made after driving over a solid, recognis-
able lane marking. Before this, a warning
must be emitted by means of intermittent
vibration in the steering wheel. In addition, a
lane with lane markings on both sides must
be recognised. The brake application also
slightly reduces driving speed.
If a lane-correcting brake application occurs,
the following appears in the multifunction dis-
play:
Example: vehicles featuring automatic transmis-
sion with a DIRECT SELECT lever

A further lane-correcting brake applica-
tion can only occur after your vehicle has
returned to the original lane.
G WARNING
Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. Corrective braking may
not always be sufficient to return your vehicle
to its original lane. In such cases, you must
steer the vehicle yourself to ensure that it
does not leave the lane.

.
Active Lane Keeping Assist cannot detect the
current traffic situation or other road users.
Ensure at all times that there is sufficient lat-
eral distance between you and other road
users or obstacles. In rare cases, broken lines
or certain structures on the road surface may
be detected by the system as solid lane mark-
ings. You can, for example, countersteer gen-
tly at any time to cancel inappropriate braking
action, e.g. if you intentionally drive across a
solid lane marking.
Active Lane Keeping Assist cannot take
weather conditions into account.
You are responsible for the vehicle's speed,
correct steering and for braking in good time.
Always adapt your driving style to suit the
prevailing road and weather conditions.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
