Controls in detail Driving systems Warning! G Warning! G DISTRONIC Plus adaptive cruise control is no substitute for active driving involvement. It does not react to pedestrians or stationary objects, nor does it recognize or predict the curvature and lane layout or the movement of vehicles ahead. DISTRONIC Plus can only apply a maximum of 40% of the vehicle's braking power. DISTRONIC Plus may not detect narrow vehicles possibly driving in front of you, such as motorcycles and vehicles driving in an offset formation. It is the driver's responsibility at all times to be attentive to road, weather and traffic conditions and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. High-frequency sources such as toll stations, speed measuring systems etc. can cause the DISTRONIC Plus system to temporarily cease functioning. DISTRONIC Plus requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. DISTRONIC Plus does not act upon adverse sight distance conditions. Do not use DISTRONIC Plus during conditions of fog and heavy rain, snow or sleet. Warning! G Warning! G DISTRONIC Plus cannot take weather conditions into account. Switch off DISTRONIC Plus or do not turn it on if: roads are slippery or covered with snow or ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid. the sensor is dirty or visibility is diminished due to snow, rain or fog. The distance control could be impaired. Always pay attention to traffic conditions even while DISTRONIC Plus is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident resulting in personal or fatal injury to you or others. DISTRONIC Plus cannot take street and traffic conditions into account. Only use DISTRONIC Plus if the road, weather and traffic conditions make it advisable to travel at a steady speed. Warning! G Use of DISTRONIC Plus can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. 444
