Side Assist provides the driver with support for lane changing. Two radar systems at the rear monitor the areas behind the car and in the blind spots at the sides. Irrespective of whether a lane change is intended, Side Assist indicates the area which is critical for lane changing. A symbol in the relevant wing mirror is lit continuously to warn the driver of the potential risk.
If the driver operates the direction indicators despite this warning, the LED concerned lights up more brightly and flashes to warn the driver of the risk. Side Assist is active at speeds of 30 km/h and higher. Side Assist is always offered together with Rear Traffic Alert as a standard feature.
