LANE DEPARTURE WARNING
(LDW) SYSTEM
DESCRIPTION
50) 51) 52) 53)
The Lane Departure Warning system
makes use of a camera located on the
windscreen to detect the lane limits and
calculate the position of the vehicle
within such limits, in order to make sure
that it remains inside the lane.
When one or both lane limits are
detected and the vehicle passes over one
without the driver's say-so (direction
indicator not turned on), the system
emits an acoustic signal.
If the vehicle continues to go beyond the
line of the lane without any intervention
from the driver, the surpassed line will
light up on the display (left or right) to
urge the driver to bring the vehicle back
into the limits of the lane.
SYSTEM ON/OFF
The system is activated/deactivated by
pressing the button, fig. 186
Each time the engine is started, the
system maintains the operating mode
that was selected when it was previously
switched off.
