Controls in detail Driving systems Parktronic system (Parking assist)*, CLK 63 AMG (USA), Canada all models 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. 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 Warning! G Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them. 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 remains with the driver. Interference caused by other ultrasonic signals (e.g. working jackhammers, car wash, or the air brakes of trucks) can cause the system to send erratic indications, and should be taken into consideration. ! The operational function of the Parktronic system can be affected by dirty sensors, especially at times of snow and ice. Make sure that the area on the bumpers around the sensors is free of dirt, ice and/or slush, otherwise Parktronic may not function properly, see "Cleaning the Parktronic system* sensors (CLK 63 AMG (USA), Canada all vehicles)" ( page 372). ! Special attention must be paid to objects with smooth surfaces or low silhouettes (e.g. trailer couplings, painted posts, elevated crossbars or road curbs). Such objects may not be detected by the system and can damage the vehicle. 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 ( page 38) and placed the gear selector lever in position D, R, or N. 1 Sensors in the front bumper 271
