Controls in detail Driving systems "DISTRONIC PLUS Currently Unavailable See Oper. Manual" appears in the multifunction display. For cleaning and care of the DISTRONIC Plus sensor, see "Cleaning the DISTRONIC Plus*/ PRE-SAFE® Brake* system sensors (USA only)"( page 599). Turns and bends Offset driving i If the message: "DISTRONIC PLUS Currently Unavailable See Oper. Manual" disappears during driving and the last speed stored flashes for approximately 5 seconds, the dirt (e.g. slush) has dissolved; DISTRONIC Plus is available again. In turns or bends, DISTRONIC Plus may not detect a moving vehicle in front, or it may detect one too soon. This may cause your vehicle to brake late or unexpectedly. A vehicle traveling in your lane but offset from your direct line of travel may not be detected by DISTRONIC Plus. There will be insufficient distance to the vehicle ahead. Another cause might be that the radar sensors have been manually switched off in the instrument cluster control system. Please verify that the radar sensors are switched on ( page 302). 459
