Lane Departure Warning (LDW)–
introduction
This function is designed to help reduce the
risk of accidents in situations where the vehicle
leaves its lane and there is a risk of driving off
the road or into the opposite lane. LDW con-
sists of a camera that monitors the lane’s side
marker lines. The driver is alerted by an audible
signal if the vehicle crosses a side marker line
or the road’s center dividing line.
Operation and function
LDW can be switched on or off by pressing the
button on the center console. A light in the but-
ton illuminates when the function is on.
The trip computer display shows Lane Depart
Warn Unavailable when the function is in
standby mode.
When LDW is in standby mode, the function is
activated automatically after the camera has
monitored the road’s side marker lines and the
vehicle’s speed exceeds 40 mph (65 km/h).
Lane Depart Warn Available will be dis-
played.
If the camera can no longer monitor the road’s
side marker lines, or if the vehicle’s speed falls
below 37 mph (60 km/h), LDW will return to
standby mode and
Lane Depart Warn
