The present invention includes a temperature-dependent power window and sunroof system for an automotive vehicle. This system according to the present invention is activated when the vehicle is presumably parked and left unattended by a vehicle operator. One aspect of the invention is directed to the detection of actions by the vehicle operator as input for system activation and deactivation, for example, the operator removes the ignition key, opens the driver door, closes the driver door and locks the door. Advantageously, if the vehicle operator stays in the vehicle after the key is removed from the ignition cylinder, the present invention remains inactivated whereby affording the maximum flexibility to the car driver. One preferred embodiment maintains a “comfortable” temperature range for the interior of the vehicle over the time period the vehicle is parked and left unattended. Moreover, to actively maintain the “comfortable” temperature range for the vehicle interior, a separate algorithm may be used. Another aspect of the invention includes means of communications to alert the vehicle operator and others in case of exceedingly high or low temperatures in the vehicle interior that might be life-threatening to those toddlers, pets or other incapacitated living beings who are left unattended in the vehicle.
