Controls in detail Driving systems DISTRONIC Plus* When activated, the DISTRONIC Plus adaptive cruise control system increases the driving convenience afforded by the cruise control while traveling on expressways and other major roadways. If the DISTRONIC Plus distance sensor detects a slower moving vehicle directly ahead, your vehicle speed will be reduced so that you follow that vehicle at your preset following distance. If there is no vehicle directly ahead of you, DISTRONIC Plus will function in the same way as standard cruise control ( page 405). DISTRONIC Plus functions within a speed range of 0 to 120 mph (Canada: 0 to 200 km/h). 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 Park Assist* ( page 435) PRE-SAFE® Brake* ( page 73) Warning! G DISTRONIC Plus is a convenience system. Its speed adjustment reduction capability is intended to make the cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver. DISTRONIC Plus cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by DISTRONIC Plus. This could result in wrong or missing distance warnings. 411
