General information on Lane Departure
Warning - LDW
The function is intended to reduce the risk for
single-vehicle accidents – accidents where, in
certain situations, the vehicle leaves the car-
riageway and is in danger of driving either into
a ditch or into oncoming traffic.
LDW consists of a camera that detects the side
markings painted on the carriageway. The
driver is alerted by an acoustic signal if the
vehicle crosses a side marking.
Operation and function
The function is switched on or off by means of
a switch on the centre console. An indicator
lamp in the button illuminates when the func-
tion is switched on.
The trip computer display shows
Lane Depart
Warn Standby <65 km/h when the function is
in standby mode due to speed being below 65
km/h.
The LDW function is activated automatically
from standby mode after the camera has scan-
ned in the carriageway's side markings and
speed exceeds 65 km/h. The trip computer
display then shows
Lane Depart Warn
Available
.
If the camera can no longer detect the carria-
geway's side markings the display shows
Lane Depart Warn Unavailable
.
If speed decreases to below 60 km/h then the
function resumes standby mode and the dis-
play shows
Lane Depart Warn Standby
<65 km/h .
If the vehicle crosses the left or right-hand side
marking of the carriageway without due cause
then the driver is alerted by an acoustic signal.
