Driver Alert System - LDW*

General information on - LDW
04
The LDW (Lane Departure Warning) function
is intended to reduce the risk of so-called sin-
gle-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 lines painted on the carriageway.
If the vehicle crosses the left or right-hand
side line of the carriageway without due
cause then the driver is alerted by an acoustic
signal.
Not available as an option for the 2.5T.

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.
Operation and function
The function is switched on or off by means
of a button on the centre console. An indica-
tor lamp in the button illuminates when the
function is switched on.
This function is complemented in the com-
bined instrument panel with intuitive graphics
in different situations. Here are several exam-
ples:
The LDW function's side lines (marked in red in
the figure).
•
The LDW symbol has WHITE side lines -
the function is active and detects/"sees"
one side line, or both.
•
The LDW symbol has GREY side lines -
the function is active but detects neither
left nor right-hand side line.
or
•
The LDW symbol has GREY side lines -
the function is in standby mode because
the speed is below 65 km/h.
•
The LDW symbol has no side lines - the
function is deactivated.
