1. REAR POWER SEAT CONTROL SYSTEM DESCRIPTION
- Power seats are standard equipment for the front seats and optional for the rear seats.

2. FUNCTION OF MAIN COMPONENT

3. SYSTEM OPERATION

Each of rear power seat's memory adjustment and positions are shown in the chart.
- By operating the rear power seat reset switch, the position of the rear seat that has been adjusted can be returned to the factory setting.
- To improve the ease of entry/exit into the vehicle, the door open linked return function is available. For this function, when a rear door is opened, the rear seat adjacent to the opened door is moved to the rearmost position.

At this time, the rear seat ECU checks the shift lever position, brake operation, ignition switch position and vehicle speed. It then makes a judgement of the vehicle's status before activating motors to move rear seat to rearmost position.

- The door open linked return function can be enabled or disabled by operating the C switch in the rear door trim.
- The right and left rear ECUs memorize seat positions for their own respective rear seat sides.
- To activate the rear vibrator function, first turn the ignition switch ON. Then press the START side of the vibrator ON switch. A vibration of 30 Hz should begin. Keep the START side of the vibrator switch held down and the vibration should increase to 60 Hz. Thereafter, the vibration drops down to 1 Hz and increases again (the sweep time is approximately 10 seconds).
