A vehicle interior assembly is provided with a console having a side-wall coupled to the console and at least one storage bin that slidingly engages the side-wall. The variable valve control system is configured to perform: controlling the valve lift characteristic to be a mechanically defined small setting in response to the calibration-mode command; collecting the information when the valve lift characteristic is the small setting; and calibrating the sensing section in accordance with the collected information. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. Then, a desired lamp luminance according to the first relation table can be determined, and then the current power is determined according to the second relation table.
