The steering column position and door mirror position is adjusted to the position automatically according to the
direction and distance of seat movement when performing the manual operation of sliding, reclining or lifting
(rear). This function saves adjusting the mirror and steering column when adjusting the seat.
NOTE:
• This function is set to OFF before delivery (initial setting).
• For the system setting procedure. Refer to 

ADP-11, "SYSTEM SETTING : Description"

.

OPERATION PROCEDURE

1.

Turn ignition switch ON.

2.

Adjust seat position [sliding, reclining, lifting (rear)].

3.

The steering and outside mirror is adjusted automatically.

NOTE:
• The seat synchronization function will not operate if seat adjusting value is more than limit value.

• The seat synchronization function will not operate if the steering column or door mirror moves to the operat-

ing end while this function is operating. Perform memory function or drive the vehicle at vehicle speed of 7
km/h or more once to activate this function again.

• If the seat position is uncomfortable after the adjustment, seat position can be adjusted easily by memory

operation.

OPERATION CONDITION

Satisfy all of the following items. The seat synchronization function is not performed if these items are not sat-
isfied.

Control unit condition

1

—

—

Perform Manual operation [Sliding, reclining or lifting (rear)].

2

Sensors
[Sliding, reclining, lifting 
(rear)]

—

The driver seat control unit judges the direction and distance of 
seat movement according to the signal input from each seat sen-
sor during manual operation.

3

—

Motors
(Tilt, telescopic, out-
side mirror)

Driver seat control unit requests the operation to position accord-
ing to the direction and distance of seat movement to the automat-
ic drive positioner control unit via UART communication. The 
automatic drive positioner control unit operates each motor.

Sensors
(Tilt, telescopic, outside 
mirror)

—

Driver seat control unit stops the operation of each motor when the 
value of each sensor that is input to automatic drive positioner con-
trol unit via UART communication reaches the target address.
