The driver seat control unit can store the optimum driving positions (seat, steering column and door mirror
position) for 2 people. If the front seat position is changed, one-touch (pressing desired memory switch) oper-
ation allows changing to the other driving position.
NOTE:
Further information for the memory storage procedure. Refer to ADP-53, "
MEMORY STORING : Description".
OPERATION PROCEDURE
1. Turn ignition switch ON.
2. Shift position P position.

1 Memory switch — The memory switch signal is inputted to the driver seat control unit
when memory switch 1 or 2 is operated.
2— Motors
(Seat, Steering,
door mirror)Driver seat control unit operates each motor of seat when it recogniz-
es the memory switch pressed for 0.5 second or more and requests
each motor operation to automatic drive positioner control unit via
UART communication. The automatic drive positioner control unit op-
erates each motor.
Memory switch Indica-
tor Driver seat control unit requests the flashing of memory indicator
while either of the motors is operating. The driver seat control unit il-
luminates the memory indicator.
3 Sensors
(Seat, steering col-
umn, door mirror) —Driver seat control unit judges the operating seat position with each
seat sensor input. The positions of the steering column and outside
mirror are monitored with each sensor signal. Driver seat control unit
stops the operation of each motor when each part reaches the record-
ed address.
4— Memory switch Indica-
torDriver seat control unit requests the illumination of memory indicator
after all motors stop. The driver seat control unit illuminates the mem-
ory indicator for 5 seconds.

1 Door switch
(Driver side)
—Driver seat control unit receives door switch signal (driver side/
open) from BCM via CAN communication.
2— Motors
(Sliding, tilt)Driver seat control unit operates the seat sliding motor, which recog-
nizes that the driver side door is opened with ignition switch OFF.
Driver seat control unit then requests the operations of tilt motor to
auto drive positioner control unit via UART communication. The au-
tomatic drive positioner control unit operates each motor for a con-
stant amount.
3 Sensor
(Sliding, tilt) —Each sensor monitors the operating positions of seat and steering,
and then stops the operation of each motor when each part reaches
the recorded address.
