MANUAL FUNCTION : System DescriptionINFOID:0000000006248306
The driving position (seat, steering column and door mi rror position) can be adjusted manually with power seat
switch, tilt & telescopic switch and door mirror remote control switch.
OPERATION PROCEDURE
1. Turn ignition switch ON.
2. Operate power seat switch, tilt & telescopic switch or door mirror remote control switch.
3. The driver seat, steering column or door mirror operates according to the operation of each switch.
NOTE:
Seat operates only up to two places at the same time.

Order Input Output Control unit condition
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.

EXIT ASSIST FUNCTION : System DescriptionINFOID:0000000006248310
 When exiting, the condition is satisfied, the seat is moved backward 40 mm (1.57 in) from normal sitting
position and the steering is moved to the most upper position.
 The seat slide amount and the steering oper ation at entry/exit operation can be changed.
NOTE:
 This function is set to ON before delivery (initial setting).
 Further information for the system setting procedure. Refer to ADP-54, "
SYSTEM SETTING : Description".
OPERATION PROCEDURE
1. Shift position P position.
2. Open the driver door with ignition switch in OFF position.
3. Driver seat and steering column will move to the exiting position.
OPERATION CONDITION
Satisfy all of the following items. The exit assist function is not performed if these items are not satisfied.

Order Input Output Control unit condition
1 Ignition switch — Driver seat control unit receives the signals of [ignition switch signal]
from BCM via CAN communication.
2— Motors
(Sliding, tilt)Driver side control unit operates the sliding motor when the operating
conditions are satisfied and requests the operations of tilt motor to
automatic drive positioner control unit via UART communication. The
automatic drive positioner operates each motor.
3 Sensors
(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.
