Radar sensors
The Side Assist radar sensors are located on the left and right side above the rear bumper ⇒ fig. 281. They cover an area of about 50 m (160 ft) behind your vehicle as well as the blind spots on the left and right vehicle side. On the left and right side of your vehicle Side Assist covers an area of about the width of one driving lane.
However, Side Assist does not recognize the exact width of the driving lanes next to your vehicle. In some cases, such as driving in the middle of 2 lanes or with very narrow lanes, this can lead to an incorrect indication. In other cases, vehicles moving on further driving lanes like the second to left lane, or even fixed objects, such as guide rails, can cause the indicator lights to light up.
