Controls in detail Driving systems Setting to last stored speed ("Resume" function) Warning! Distronic* Warning! When activated, the Distronic adaptive cruise control system increases the driving convenience afforded by the cruise control while traveling on expressways and other major roadways. If 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. If there is no vehicle directly ahead of you, Distronic will function in the same way as standard cruise control ( page 257). G G The set speed stored in memory should only be set again if prevailing road conditions permit. Possible acceleration or deceleration differences arising from returning to the preset speed could cause an accident and/or serious injury to you and others. 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. Distronic cannot take road and traffic conditions into account. Complex driving situations are not always fully recognized by Distronic. This could result in wrong or missing distance warnings. Briefly pull the cruise control lever in direction of arrow 4 ( page 258). The cruise control resumes to the last set speed, or if no speed is stored, it will set and store the current speed. Remove your foot from the accelerator pedal. The last set speed appears in the multifunction display for approximately 5 seconds. 262
