Your Hyundai has a mode (footwell/headwell) that allows warm air to be supplied through the footwell vents and cooler air to be supplied through the overhead vents. To turn on this mode:
Set the air intake mode selector switch to mode outside air intake.
Set the ventilation mode selection knob to the position (to the legs / to the head area)
Set the air temperature control knob between the "Cool" and "Warm" positions.
