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 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 LDW
(The figure is schematic - not model specific.)
A camera reads the side lines of the road/lane.
Warning with steering wheel vibration
26
.
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 var-
ies - 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 responsibility
for ensuring that the vehicle is driven safely
and that applicable laws and road traffic regu-
lations are followed.
