Controls in detail Driving systems Rear Park Assist* Warning! The Rear Park Assist system monitors the rear area of your vehicle by means of four sensors in the rear bumper. G Rear Park 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 Park Assist can be affected by dirty sensors, especially at times of snow and ice. See "Cleaning the Rear Park Assist sensors" ( page 234). 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 that no persons or animals are in the area in which you are maneuvering. You could otherwise injure them. The Rear Park 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 Park Assist system is automatically activated when you switch on the ignition and shift the gear selector lever to position R. 1 Sensors 165
