Abstract: A control system for a vehicle situated device includes a shut-out arrangement denying access to, or disabling an adjustment feature of the device but permitting the device to operate in a predetermined mode of operation when the vehicle is in a first state of operation. The shut-out means is disabled or overridable when the vehicle is in an alternate state of operation, thereby permitting the respective adjustment feature to be accessed or enabled. The shut-out arrangement is typically operated to deny access to or disable the relevant adjustment feature of the vehicle situated device when the vehicle engine is running and/or when the vehicle is in motion. The arrangement reduces driver distraction and thereby reduces driver error and the risk of accident.
