RIf the Distronic 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 will function in the same way as standard cruise control (Y page 142). G Warning! The Distronic requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. G Warning! When the Distronic is braking, the brake pedal is retracted (i.e. depressed automatically). The pedals' range of motion must not be impeded by any obstacles: RDo not place any objects in the footwell. The Distronic 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 lane curvature or the movement of preceding vehicles. The Distronic can only apply 20% of the maximum braking power of the vehicle. 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 system to malfunction. G Warning! RMake sure that the floormats and carpets are securely in place. pedal, as it could otherwise be trapped. G Warning! RDo not rest your foot underneath the brake The Distronic cannot take road and traffic conditions into account. Only use the Distronic if the road, weather and traffic conditions make it advisable to travel at a constant speed. Z Controls in detail Briefly pull the cruise control lever in direction of arrow ?. If no speed is stored, the current speed is set and stored. X Remove your foot from the accelerator pedal. The last stored speed is deleted from memory when the engine is turned off. You could otherwise cause an accident and injure yourself and/or others. The Distronic 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 cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by the Distronic. This could result in wrong or missing distance warnings. G Warning!
