Controls in detail Driving systems Warning! G Switch off DISTRONIC Plus: when changing from the left to the right lane if vehicles are moving more slowly in the left lane when entering a turn lane or highway off ramp in complex driving situations, such as in highway construction zones In these situations, DISTRONIC Plus will continue to maintain the set speed unless deactivated. DISTRONIC Plus is designed and intended only to maintain a set speed and keep a set distance from moving objects in front of it. i Do not use DISTRONIC Plus if you are driving on a road with steep uphill or downhill slopes. The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed. i Due to its radar-emitting nature DISTRONIC Plus may have an appearance similar to a radar detector to law enforcement officials. You may want to refer to this section of your Operator's Manual when asked. Warning! G Close attention to road and traffic conditions is imperative at all times, regardless of whether or not DISTRONIC Plus is activated. Use of DISTRONIC Plus can be dangerous on winding roads as conditions do not allow safe driving at a steady speed. DISTRONIC Plus may not react to stationary objects in the roadway (e.g. a stopped vehicle in a traffic jam or a disabled vehicle). DISTRONIC Plus will also not respond to oncoming vehicles. i USA only: This device has been approved by the FCC as a "Vehicular Radar System".
