Controls in detail Driving systems Rear Parking Assist* The Rear Parking Assist system monitors the rear area of your vehicle by means of four sensors in the rear bumper. Warning! G Rear Parking Assist (rear Parktronic) is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always rests with the driver. Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, or street curbs). Such objects may not be detected by the system and can damage the vehicle. The operational function of the Rear Parking Assist can be affected by dirty sensors, especially at times of snow and ice. See "Cleaning the Rear Parking Assist sensors" ( page 283). Interference caused by other ultrasonic signals (e.g. working jackhammers or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration. Warning! G Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them. The Rear Parking Assist system is an electronic aid designed to assist the driver during parking maneuvers. It visually and audibly indicates the relative distance between the rear of the vehicle and an obstacle. The Rear Parking Assist system is automatically activated when you switch on the ignition and shift the gear selector lever to position R. 1 Sensors 179
