Abstract

A method and system for controlling one or more functions associated with a vehicle display includes providing a steering wheel having a left zone and a right zone. The method includes determining a left contact value and a right contact value based on at least one of a plurality of sensors of the steering wheel. Further, the method includes comparing the left contact value to a left contact threshold that maximizes contact of a left hand with the steering wheel within the left zone and comparing the right contact value to a right contact threshold that maximizes contact of a right hand with the steering wheel within the right zone. Upon determining a non-driving passenger is present in the vehicle, the one or more functions associated with the vehicle display are enabled or disabled.
