Lane Keeping Aid (LKA)*
The purpose of Lane Departure Warning is to
help the driver to reduce the risk of the vehi-
cle accidentally leaving its own lane in certain
situations 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 vibra-
tion 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 deter-
mine which of the systems the car is equip-
ped 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 tor-
que in the steering 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 responsi-
bility for ensuring that the vehicle is driven
safely and that applicable laws and road
traffic regulations are followed.
