The feature can tell when a driver strays from a lane unintentionally, providing a visual message in the instrument cluster and initiating corrective steering. The system is active on condition that there are recognisable lane markings on the road and the indicator has not been turned on prior to crossing a marking.

Driver Alert reduces the risk of a fatigue-induced emergency situation. By monitoring driver behaviour, the system assesses the degree of driver fatigue and, if necessary, warns of the need for a rest and break in the journey.
