Lane Departure Warning (LDW)*
The purpose of Lane Departure Warning
(Lane Departure Warning) is to help the driver
to reduce the risk of the vehicle 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 LDW
(The figure is schematic - not model specific.)
A camera reads the side lines of the road/
lane.
Warning with steering wheel vibration
24
.
If the car crosses one of the side lines the
driver is alerted with an acoustic signal or
vibration in the steering wheel. Steering wheel
vibration varies - the longer the time for which
the car has crossed the side line, the longer
the vibration.
NOTE
The driver is only warned once each time
the wheels cross a line. So there is no
acoustic alarm when there is a line
between the car's wheels.
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.
