• AV control unit transmits the front heated seat switch indicator signal to the display unit via AV communication.

• When the display unit receives the front heated seat switch indicator signal, it turns ON the indicator for the front heated seat switch on the display.

HEATER CONTROL

• Front seat cushion heater is integrated with the heat sensor that detect the seat temperature. Heat sensor transmit the seat temperature as the heat sensor signal to CPU integrated with the front seat cushion heater.

• CPU recognizes the seat temperature from heat sensor signal. It adjusts the seat temperature by stopping operation when the seat temperature reaches the operation stop temperature , and starting operation when the seat temperature reaches the operation start temperature .

  

  Preset temperature	Temperature °C (°F)
  	Temperature at operation stop	Temperature at operation start
  Low	38 (100.4)	36 (96.8)
  Mid	40 (104.0)	38 (100.4)
  High	42 (107.6)	40 (104.0)

Rear Heated Seat System

System Description

SYSTEM DIAGRAM

DESCRIPTION

• Rear heated seat system operates during READY and warms the rear seats.

• Rear heated seat system is operated by the rear heated seat switch on the display, or by the rear heated seat switch that is installed on the center console finisher rear upper.

• Rear heated seat system is rear seat LH and rear seat RH operate independently.

• Temperature setting of rear heated seat system can be adjusted at 3 levels (Low, Mid, High).

• Operation status of the rear heated seat system can be checked from the indicator of the rear heated seat switch on the display, and the indicator of the rear heated seat switch that is installed on the center console finisher rear upper.

OPERATION DESCRIPTION

Operation of the rear heated seat switch on the display.

• When the READY status and the rear heated seat switch on the display is operated, the display unit transmits the rear heated seat switch operation signal to the AV control unit via AV communication.

• AV control unit transmits the rear heated seat switch operation signal to the A/C auto amp. via CAN communication.

• When the A/C auto amp. receives the rear heated seat switch operation signal, it transmits the rear heated seat control signal to the rear seat heater via LIN communication to operates the rear heated seat system.

• At the same time when the rear heated seat system is operated, the A/C auto amp. transmits the rear heated seat switch indicator signal to the AV control unit via CAN communication.

• AV control unit transmits the rear heated seat switch indicator signal to the display unit via AV communication.

• When the display unit receives the rear heated seat switch indicator signal, it turns ON the indicator for the rear heated seat switch on the display.

Operation of the rear heated seat switch that is installed on the center console finisher rear upper.

• When the READY status, and the rear heated seat switch that is installed on the center console finisher rear upper is operated, the A/C control transmits the rear heated seat switch operation signal to the AV auto amp. via LIN communication.

• When the A/C auto amp. receives the rear heated seat switch operation signal, it transmits the rear heated seat control signal to the rear seat heater via LIN communication to operates the rear heated seat system.

• At the same time when the rear heated seat system is operated, the A/C auto amp. transmits the rear heated seat switch indicator signal to the A/C control via LIN communication.

• When the A/C control receives the rear heated seat switch indicator signal, it turns ON the indicator for the rear heated seat switch.

HEATER CONTROL

• Rear seat cushion heater is integrated with the heat sensor that detect the seat temperature. Heat sensor transmit the seat temperature as the heat sensor signal to CPU integrated with the rear seat cushion heater.

• CPU recognizes the seat temperature from heat sensor signal. It adjusts the seat temperature by stopping operation when the seat temperature reaches the operation stop temperature , and starting operation when the seat temperature reaches the operation start temperature .

  

  Preset temperature	Temperature °C (°F)
  	Temperature at operation stop	Temperature at operation start
  Low	38 (100.4)	36 (96.8)
