Function 

The type, location and number of operating elements and indicators in the upper control panel vary depending on the model and equipment. Unlike the pushbuttons used previously, the buttons on telematics unit version NTG 7 (with the exception of the hazard warning light system button) are touch-sensitive. The fingerprint sensor (model dependent) is located in the upper control panel. The display angle button (model dependent) is located in the upper control panel.

On vehicles with NTG 7, the upper control panel is connected to the vehicle's network architecture.
