A vehicle includes a radio receiver configured to receive emergency alert messages initiated by an alerting authority and broadcast by an alerting disseminator. The radio receiver is normally inactive when the vehicle is in the dormant state. A user monitor is configured to track a user during a time that the vehicle is in the dormant state to detect whether the user remains in the vehicle or is within a predetermined distance of the vehicle. A controller coupled to the radio receiver and to the user monitor is configured to activate the radio receiver during the dormant state when the user is present. The controller detects the existence of a relevant emergency alert message and initiates an annunciation signal which is generated by the vehicle and perceptible to the user to inform the user that the relevant emergency alert message is available.
