I know you can tell if a W210 has the sport package based on the E55 floormats, and the Navigation system is easy, but what about the Ventilated Seats? Where exactly is the button?

Thanks!

 

the ventilation button is on the bottom part of the heated seats button...on the center console to the left and right of the large red "hazard" button

if you just have heated seats....you'll have to "power" setting for the heater
the ventilated seats with heat have the heater (top of button) and ventilation (bottom of button)
