Memory Retrieve

When one of the two buttons on the driving position memory switch is pressed with the vehicle parked (A/T: shift lever in P position) (M/T: shift lever in neutral, parking brake on) and the driver's door closed, the seat and the mirrors move to the memorized positions.

Power Seat Position Sensors

Each motor has a 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 a tilt position sensor and swing position sensor, the power mirror control circuit in the power mirror 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 for each stored driving position.

Reverse Mirror Control

When the vehicle is shifted to Reverse (shift lever in R position) with the power mirror selector switch in Left (or Right) position, the driver's (or passenger's) side mirror tilts down automatically to help the driver's view. The mirror will return to the previous position when the shift lever is shifted out of R position. The reverse mirror control is cancelled if the power mirror selector switch is in the center position.

With the HDS

Use the HDS to clear DTCs in the power seat/mirror mode of the body electrical system select menu.

Without the HDS

Make sure you have the anti-theft codes for the audio system and the navigation system (if equipped). Make sure the ignition switch is OFF. Disconnect the negative battery cable for at least 30 seconds. After reconnecting the battery, enter the anti-theft codes for the audio system and the navigation system, then set the clock (on vehicles without navigation).

Erasing the Driving Position from Memory

  1. Press and hold all three driving position memory switch bottoms.
  2. Turn the ignition switch ON (II).
  3. Continue to hold all three driving position memory switches for more than 5 seconds, and release them in less than 10 seconds.
  4. The buzzer will sound for 500 ms to confirm that all driving position data is erased.
