Controls in detail Driving systems Rwith Rif the electronic parking brake engaged the ESP® has switched off due to a malfunction DISTRONIC Plus Safety notes 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. RIf 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. RIf there is no vehicle directly ahead of you, the DISTRONIC Plus will function in the same way as standard cruise control (Y page 347). G Warning! The DISTRONIC Plus is a convenience system. Its speed adjustment reduction capability is intended to make 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's speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver. The DISTRONIC Plus cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by the DISTRONIC Plus. This could result in wrong or missing distance warnings. G Warning! The DISTRONIC Plus adaptive cruise control is not a substitute for active driving involvement. It does not react to pedestrians or on stationary objects, nor does it recognize or predict the curvature and lane layout or the movement of preceding vehicles. The DISTRONIC Plus can only apply a maximum of 40% of the vehicle's braking power. The 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 the road, weather and traffic conditions. Additionally, the driver must provide the steering, braking and other driving inputs necessary to remain in 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. G Warning! The DISTRONIC Plus requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. G Warning! The DISTRONIC Plus cannot take road and traffic conditions into account. Only use the DISTRONIC Plus if the road, weather and traffic conditions make it advisable to travel at a constant speed. G Warning! Use of the DISTRONIC Plus can be dangerous on slippery roads. Rapid 350
