					As soon as the road is clear, the vehicle accel‐  
					erates to the desired speed.  
					Vehicle features and options  
					This chapter describes all standard, country-  
					specific and optional features offered with the  
					series. It also describes features that are not  
					necessarily available in your car, e. g., due to  
					the selected options or country versions. This  
					also applies to safety-related functions and  
					systems. The respectively applicable country  
					provisions must be observed when using the  
					respective features and systems.  
					The speed is also maintained downhill, but  
					may not be maintained uphill if engine power is  
					insufficient.  
					General information  
					Depending on the driving settings, the features  
					of the cruise control can change in certain  
					areas.

					Personal responsibility  
					Even an active system holds the driver  
					responsible for his or her driving, particularly  
					for staying in your lane, adjusting your speed,  
					keeping your distance and for your driving  
					style all in relation to traffic.  
					The concept  
					Use this system to select a desired speed that  
					the vehicle will maintain automatically on clear  
					roads.  
					Technically the system has its limits, it cannot  
					independently react to all traffic situations.  
					To the extent possible, the system automati‐  
					cally adjusts the speed to a slower vehicle  
					ahead of you.  
					Monitor your driving, be on the alert, observe  
					the vehicle surroundings and other traffic and  
					react when needed, e.g. through braking,  
					steering or make evasive maneuvers - risk of  
					accident.◀  
					The distance that the vehicle maintains to the  
					vehicle ahead of you can be varied.  
					For safety reasons, it depends on the speed.  
					To maintain a certain distance, the system au‐  
					tomatically reduces the speed, applies the  
					brakes lightly, or accelerates again if the vehi‐  
					cle ahead begins moving faster.  
					Unfavorable weather conditions  
					In the event of unfavorable weather and  
					light conditions, e. g. if there is rain, snowfall,  
					slush, fog or glare, this may result in poorer  
					recognition of vehicles as well as short-term  
					interruptions for vehicles that are already de‐  
					tected. Drive attentively, and react to the cur‐  
					rent traffic situation. Intervene actively when  
					necessary, e.g., by braking, steering or making  
					an evasive maneuver, otherwise, there is the  
					risk of an accident.◀  
					If the vehicle ahead of you brakes to a halt, and  
					then proceeds to drive again within a brief pe‐  
					riod, the system is able to detect this within the  
					given system limits. Your own vehicle will  
					brake automatically and then accelerate again.  
					If the vehicle ahead of you drives away again  
					after a prolonged period, briefly press the ac‐  
					celerator pedal or press the appropriate button  
					to reactivate the system. The vehicle will auto‐  
					matically accelerate.
