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.

Thanks to two radar sensors at the rear of the car, the Side Assist detects vehicles approaching from behind or that are in the car’s blind spot. The driver is informed of this using an LED signal on the inside of the wing mirror housings. While the existing Blind Spot Detect has a range of up to 20 m, Side Assist can detect vehicles up to 70 m away and thus also effectively warns the driver of hazardous situations on motorways and dual carriageways.

The system processes speed limit signs, no overtaking signs and any supplementary instructions, and associated restriction clearance signs. They are shown as pictograms in the multi-functional display and/or the navigation system display.

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.
