following preconditions must be fulfilled:

approx. 40 mph and 112 mph
● the turn lights are not activated
● no dynamic driving, i.e. pressure on the
brake or accelerator pedal
● lane boundaries can be clearly
detected by the system
● the vehicle is not driven in a tight
corner
● no system fault is present that prevents
corrections
Activation
Depending on version, the system is
automatically active by default every time
the engine is started, even if it was
deactivated during the last ignition cycle.

Stop the vehicle and check, if the
camera needs to be cleaned. If still

Lane Keeping Assist (LKA)
Lane keeping assist supports the driver
to avoid unintended leaving of the lane.
The front camera observes road edges,
as well as the lane markings between
which the vehicle is driving.
If the vehicle approaches a road edge
or a lane marking, the steering wheel is
gently turned so that the vehicle turns
back into the lane. The driver will notice a
turning movement of the steering wheel.
Turn steering wheel in same direction,
if the system does not steer sufficiently.
