System Description

  1. GENERAL 

    The climate control seat system creates cold or warm air to increase the comfort of seats that have become hot or cold.

    The air is heated or cooled by the Peltier element on the back of the seat cushion pad and seatback. The air is then sent to the seat cushion and seatback with the fan installed under the seat. The fan is operated by pressing the climate control seat switch.

    The climate control seat switch has several modes that vary the quantity of air to be sent to the seat. There are 7 modes in total: 3 cooled air modes, 3 heated air modes and ventilation mode.

    HINT:

    When the highest level for cooled air operates for 15 minutes, the quantity of air falls 1 level.
