Abstract: An vehicle with abandoned occupant alert system incorporates a pad having a global positioning tracking device, a radio-frequency identification (RFID) chip, a wireless transmitter, and a temperature gauge. The pad also comprises a heating and cooling mechanism which is activated in response to the interior temperature of the vehicle. The pad is configured to transmit a signal to an electronic device equipped with an application which alerts a user to the presence of an individual of sufficient weight sitting upon the pad in an unoccupied vehicle the engine of which has been shut off.
