Abstract: A vehicle, system, and method provide determining whether a thermal risk exists for an occupant of a passenger compartment of a vehicle based on: identifying, via the temperature sensor, that the temperature within the passenger compartment is outside of a safe temperature range, identifying, via an electronic control module, that an engine of the vehicle is not running, and identifying, via the occupant sensor, that an occupant is in the passenger compartment. In response to determining that the thermal risk exists, a controller starts starting the engine via an ignition locking system, closes power-actuated windows of the passenger compartment, locks power-locked doors of the passenger compartment, and activates a heating, ventilation and air conditioning system of the vehicle via a climate control unit. The HVAC maintains the temperature of the passenger compartment within the safe temperature range to safeguard the occupant until return of a responsible party.
