Heated/Ventilated Seat Operation

The heated/ventilated seat system consists of the following components:

• Seat cushion heater mat
• Seat backrest heater mat
• Blower motor, located within each front seat cushion and backrest
• HVAC module (includes heated/ventilated seat buttons)
• DSM
• Cushion and backrest vent bags (part of the cushion and backrest foam)
• Air duct (bellow)
• Cushion and backrest foam
• Cushion and backrest trim covers

The driver and passenger heated/ventilated seat buttons are selected from the HVAC module. The heated/ventilated seat system functions independently from the vehicle's climate control system.

Heat Operation 

• The system control settings are indicated next to each heated/ventilated seat switch button. The first setting is HIGH (3 indicators), the second setting is MED (2 indicators) and the third is LOW (1 indicator) then OFF (no indicators).
• When activated, the DSM supplies voltage to the selected seat heater circuit. Each seat cushion heater mat and backrest heater mat is connected in a series circuit to the DSM and powered by the output circuit for that seat. The DSM monitors inputs from a temperature sensor located in each seat cushion heater mat, and maintains seat temperature by cycling the heater circuits on/off. The heated seat remains ON until the heated seat switch button is pressed to cycle the DSM OFF or the ignition is set to OFF.

Ventilation Operation 

• The seat cushion and backrest are each equipped with a blower motor assembly. Each blower motor draws air through the surface of the cushion and backrest through the foam. Once the system is activated, the DSM controls the blower speed dependant on the heated/ventilated seat settings.
• The system control settings are based on the 3 indicators next to each heated/ventilated seat switch button. The first setting is HIGH (3 indicators), the second setting is MED (2 indicators) and the third is LOW (1 indicator) then OFF (no indicators).
