Abstract

A vehicle interface input receiving method comprises operating a controller to selectively enter or refrain from entering a user input device controlling mode. While in the user input device controlling mode, the method determines a presence of first and second contact conditions at first and second predetermined locations, respectively, with the first contact condition being on a vehicle steering wheel, and controls a user input device to change from a deactivated state to an activated state in response to the simultaneous existence of the first and second contact conditions. Also, an indicator provides an indication of the activated state, and the user input device is maintained in the activated state while the first contact condition continues to exist. The user input device provides input to the controller in the activated state and refrains from providing such input in the deactivated state, and afterward returns to the deactivated state.
