Controls in detail Driving systems When travelling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system* ( page 272). Canadian law does not permit the use of the radar sensor system* ( page 272) for vehicles from outside of Canada. When you switch off the radar sensor system*, the following functions are deactivated: BAS Plus* ( page 67) DISTRONIC Plus* ( page 411) Park Assist PRE-SAFE® Brake* ( page 73) It visually and audibly indicates the relative distance between the vehicle and an obstacle. Park Assist is automatically activated when the engine is running and the transmission is in position D, R or N. The Park Assist system deactivates at speeds over approximately 11 mph (18 km/h). At lower speeds the Parktronic system turns on again. Park Assist is also switched off when you set the automatic transmission to P or switch off the engine. While the transmission is in position N, Park Assist is switched off if you secure the vehicle in place with the electronic parking brake. The Park Assist system monitors the surroundings of your vehicle with four sensors in the front bumper and two sensors in the rear bumper. Range of the sensors The sensors of the Park Assist system are integrated in the front and rear bumpers. Make sure that the bumpers are clear of dirt, ice and slush in the area of the sensors, as otherwise, Park Assist may not function properly, see "Cleaning the Park Assist* system sensors" ( page 559). 436
