A vehicle personal assistant to engage a user in a conversational dialog about vehicle-related topics, such as those commonly found in a vehicle owner's manual, includes modules to interpret spoken natural language input, search a vehicle knowledge base and/or other data sources for pertinent information, and respond to the user's input in a conversational fashion. The dialog may be initiated by the user or more proactively by the vehicle personal assistant based on events that may be currently happening in relation to the vehicle. The vehicle personal assistant may use real-time inputs obtained from the vehicle and/or non-verbal inputs from the user to enhance its understanding of the dialog and assist the user in a variety of ways.
