 Temperature of seat can be adjust ed by operating on heated seat switch.
CLIMATE CONTROLLED SEAT SYSTEM
CLIMATE CONTROLLED SEAT SYSTEM : System DiagramINFOID:0000000006217376
CLIMATE CONTROLLED SEAT S YSTEM : System DescriptionINFOID:0000000006217377
 The climate controlled seat system is controll ed by the climate controlled seat control unit.
 Operation of the climate controlled switch sends heat ed or cooled airflow and adjusts the seat temperature.
SEAT CUSHION AND SEATBACK TEMPERATURE ADJUSTMENT FUNCTION
 One thermal electric unit (TEU) unit is installed in each seat cushion and seatback. The unit heats or cools,
sends airflow to the seat surface, and adjusts the seat temperature.
 The thermal electric unit (TEU) is a heat exchanger that has a function to heat or cool the airflow from the
seat cushion blower motor and seatback blower motor. (By changing the direction of the current from the
power supply, the unit takes or gives heat, and adjusts exchange process depending on voltage.
CAUTION:
 The thermal electric unit (TEU) has a dual-climate fu nction that allows one side to operate at a high
temperature and the other to operate at a low temperature simultaneously.
 Before starting always turn OFF the switch and check that the electric unit is cold.
CLIMATE CONTROLLED SEAT SYSTEM : Fail-safeINFOID:0000000006217378
