Lane Keeping Aid (LKA)*
The purpose of Lane Departure Warning is to
help the driver to reduce the risk of the vehicle
accidentally leaving its own lane in certain situa-
tions on motorways and similar major routes.
Lane Departure Warning LDW or LKA
There are two versions of Lane assistance:
•
LDW -
Lane Departure Warning - alerts
the driver with an acoustic signal or vibration
in the steering wheel.
•
LKA -
Lane Keeping Aid
(Lane Keeping Aid) - steers the car back into
its lane and/or alerts the driver with an
acoustic signal or vibration in the steering
wheel.
The car is supplied with one of these two sys-
tems - market and engine alternative determine
which of the systems the car is equipped with.
In the event of uncertainty whether the car has
LDW or LKA:
•
Open the menu system MY CAR and locate
Driver support system - which specifies
Lane Departure Warning if the car has
LDW or Lane Keeping Aid for LKA.
Principle for LKA
(The figure is schematic - not model specific.)
A camera reads the side lines of the road/lane.
If the car is about to cross a side line then Lane
Keeping Aid will actively steer the car back into
the lane with a slight steering torque in the steer-
ing wheel.
If the car reaches or crosses a side line then
Lane Keeping Aid will also alert the driver with
vibration in the steering wheel.
WARNING
Lane assistance is merely a driver aid and
does not engage in all driving situations or
traffic, weather or road conditions.
The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely
and that applicable laws and road traffic regu-
lations are followed.
