Some driving and driving safety systems use radar or ultrasonic sensors to monitor the area in front of, behind or next to the vehicle (depending on the vehicle's equipment).

Depending on the vehicle's equipment, the radar sensors are integrated behind the bumpers and/or behind the radiator grille. The ultrasonic sensors are located in the front and rear bumpers. Keep these parts free of dirt, ice and slush More. The sensors must not be covered, for example by bicycle racks, overhanging loads, stickers, foil or foils to protect against stone chipping. Additional licence plate brackets can likewise impair the function of the ultrasonic sensors. In the event of damage to the bumpers or radiator grille, or following a collision impacting the bumpers or radiator grille, have the function of the sensors checked at a qualified specialist workshop. If the sensors are damaged, some driving systems and driving safety systems may no longer function properly.
