Ok....I own a B250e but it is basic with no technology. So if I can add an image here I will but here is my questions. Starting on the left, there is the driver's seat heating button then next is a strange button for varying the fan speed for whatever ? Next is the drive mode, but what is E+ ?? Next the emergency triangle and next is what ? The range extender ( adding approx 17 miles to the range ) or what ? And next might be for Parktronic (automatic parallel parking ??) and does mean the car has front and back parking sensors that work ??? And then finally the passenger seat heating . Thanks
