A vehicle includes a body having a door and a door latch, a display screen, front and rear seats, a seat belt, buckle and door latch sensors, and a controller. The latch sensors determine a latch state of the seat belt buckle and door latch. The controller determines the respective latch states of the seat belt buckle and the door latch via the respective latch sensors. The controller also displays a first icon/message via the display screen in response to an ignition-off event, with the icon or message prompting a driver to check the rear seat for the presence of a passenger or object. A second control action is executed by the controller in addition to the first control action in response to the latch state of the seat belt buckle and/or door latch being in the latched or closed latch state for less than a calibrated amount of time.
