Seat Position Memory System Description (With Seat Position Memory System)

Basic Operation 

The front passenger's power seat control unit controls each power seat motor based on signals from the front passenger's power seat adjustment switch. The front passenger's power seat control unit activates the lumbar support by operating the lumbar support adjustment switch in the front passenger's power seat adjustment switch.

Memorizing a Seat Position 

Turn the vehicle to the ON mode, then move the seat to the desired position. Press and hold the SET button on the driving position memory switch. A single beep will be heard and both of the green LED will begin to flash. Press No. 1, No. 2, or No. 3 to match the setting that is to be used. There will be two more beeps confirming that the seat positions have been memorized. The LED will remain lit, unless the seat is moved from the memorized position.

Memorized Position Recall 

With the shift position in ATP-P and one of the buttons (No. 1, No. 2, or No. 3) that has a memorized seat position set is pressed, the front passenger's seat moves to the memorized position. While the memory seat is being operated, the corresponding indicator of the front passenger's memory switch flashes, and when the operation is completed, the indicator turns off.

Failsafe Function 

When a failure occurs in the inputs of the power supply and B-CAN signals, or the control unit is abnormal, the failsafe function disables the seat position memory system function.
