Caution
The system is intended to help the

range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any
other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do
not relieve the driver from full
responsibility for vehicle
operation.

Lane keep assist

Lane keep assist supports the driver
to avoid unintentional crossing of lane
markings. The front camera observes
the lane markings between which the
vehicle is driving. If the vehicle
Driving and operating
approaches a lane marking without
activated turn signal, the steering
wheel is gently turned to position the
vehicle back into the lane. Turn
steering wheel in same direction, if
system steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.
The Lane Keep Assist informs the
driver with an optical warning during
the trajectory correction. If the system
is not able to avoid the lane crossing
an additional acoustic warning is
issued.
Unintended lane departure is
assumed:
● without using the turn lights
● using the turn lights in the
opposite direction of the lane
departure
● without braking
● without acceleration
● without active steering
Notice
The system might be inactive when
the detected lane markings are
ambiguous or insufficient, e.g. in
construction areas.
