System Descriptions

The driver's seat and the power mirrors have a memory feature. The seat and mirror adjustments can be regulated separately. All the adjustments can be memorized by pressing the MEMO button on the driving position memory switch, and then pressing one of the two position buttons within five seconds. Pressing the appropriate position button will move the seat and the mirrors to the memorized position. Disconnecting the battery will cancel the memorized positions.

Power Seat Position Sensors:
Each motor has a Hall-effect sensor which detects motor rotation and sends a pulse to the power seat control unit when the motor rotates. The control unit stores the number of pulses in its memory, and the seat position is memorized.

Power Mirror Position Sensors:
By means of potentiometer position sensors, the power mirror control circuit in the passenger's multiplex control unit detects the voltage changes caused by the movements of the mirrors.
These voltage changes are stored in memory, and the power mirror positions are memorized.

Recline Switch (Limit Switch):
The recline switch consists of two limit switches. When the seat back is tilted forward to enter the rear seat, one of the limit switches detects the position, and the power seat control unit makes the seat move forward by sending power to the slide motor. When the seat back is returned to upright position, another limit switch detects the position, and the power seat control unit sends power to the slide motor to move the seat bottom to its original position.

Memory Retrieval:
When one of the two buttons on the driving position memory switch is pressed with the vehicle parked (A/T: shift lever in [P], M/T: parking brake lever pulled) and the driver door closed, the seat and the mirrors move to the memorized positions. The remote transmitters will also activate the DPMS.

NOTE: Vehicles with M/T also have a "push and hold" memory retrieval. If the parking brake lever is off (not pulled) the seat can be moved to a memorized position by pushing and holding one of the two position buttons until the seat stops moving.
