Controls in detail Driving systems The Parktronic system monitors the surroundings of your vehicle with six sensors in the front bumper and four sensors in the rear bumper. Warning! G Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them. The Parktronic system is an electronic aid designed to assist the driver during parking maneuvers. It visually and audibly indicates the relative distance between the vehicle and an obstacle. The Parktronic system is automatically activated when you switch on the ignition, release the parking brake, and placed the gear selector lever in position D, R, or N. The Parktronic system deactivates at speeds over approximately 11 mph (18 km/h). At lower speeds the Parktronic system turns on again. The Parktronic system also deactivates when you place the gear selector lever in position P or depress the parking brake pedal. 1 Sensors in the front bumper Range of the sensors To function properly, the sensors must be free of dirt, ice, snow and slush. Clean the sensors regularly, being careful not to scratch or damage the sensors, see "Cleaning the Parktronic system* sensors" ( page 368). 264
