*: Door mirror operation starts with the start of seat sliding operation.
Storing Memory Procedure
1. Turn ignition switch to ON.
2. Shift A/T selector lever to P position.
3. Adjust position of driver seat, steering and mirror position.
4. Press set switch.
Indicator LED for which driver seat positions are already retained in memory is illuminated for 5 sec-
onds.
Indicator LED for which driver seat positions are not retained in memory is illuminated for 0.5 second.
5. Press memory switch for which driver seat positions are to be entered in memory for more than 0.5 sec-
ond within 5 seconds after pressing the set switch (during the indicator LED is illuminated).
To enter driver seat positions in blank memory, indicator LED will be illuminated for 5 seconds.
To modify driver seat positions, indicator LED will be turned OFF for 0.5 second then illuminated for 5
seconds.
6.
If you need setting of INTELLIGENT KEY INTERLOCK OPERATION, continue this procedure.
If you don't need setting of INTELLIGENT KEY INTERLOCK OPERATION, the procedure is finished.
Conform the operations of each part with the MEMORY OPERATION.
7. Press intelligent key unlock button within 5 seconds after pressing memory switch.
(While memory switch LED is illuminated.)
8. Conform the operations of each part with MEMORY OPERATION and INTELLIGENT KEY INTERLOCK
OPERATION.
NOTE:
Driving position is erased from the memory when battery cable is disconnected.

EXITING OPERATION
When exiting, when 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 and front position.
The seat slide amount and the steering operation at entry/exit operation can be changed by set switch, CON-
SULT-II and display (located in the instrument panel). Refer to SE-16, "
SETTING CHANGE FUNCTION" .
Operation Condition
Ignition switch: OFF / Driver side door switch: ON (OPEN)
If the following conditions are not satisfied, exiting operation is not performed.
Ignition switch is in OFF position.
A/T selector lever position is in P position.
Vehicle speed is less than 7 km/h. (4 MPH).
Driver side power seat switch and ADP steering switch are not operated.
Seat memory switch and set switch is not operated.
Door mirror control switch is not operated at change over switch is in LH or RH position.
Output malfunction is not detected.
Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF and vehicle speed is higher
than 7 km/h. (4 MPH).]
CAN communications are normal.
Initialization has been done. Refer to SE-16, "INITIALIZATION PROCEDURE" .
ENTRY OPERATION
When the seat is in the exiting position when either condition (1 or 2) is satisfied, the seat returns from exiting
position to the previous driving position.
Operation Condition
1. Ignition switch: ON
2. Ignition switch: ACC / Driver side door switch: OFF (CLOSE)
If the following conditions are not satisfied, entry operation is not performed.
Ignition switch is in OFF position.
A/T selector lever position is in P position.
Vehicle speed is less than 7 km/h (4 MPH).
Driver side power seat switch, ADP steering switch and door mirror control switch are not operated.
Seat memory switch and set switch is not operated.
Output malfunction is not detected.
Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF and vehicle speed is higher
than 7 km/h (4 MPH).]
CAN communications are normal.
Exiting positions have not been changed during and after exiting operation.

INTELLIGENT KEY INTERLOCK OPERATION
When pressing unlock button on Intelligent Key or request switch, the system performs memory operation,
exiting operation and entry operation.
Operation procedure
1. Press unlock button on Intelligent Key or request switch.
2. The system performs MEMORY OPERATION, and then performs EXITING OPERATION continually.
NOTE:
If the seat position is in memorized position before push unlock button, MEMORY OPEPATION dose not per-
form.
3. Turn ignition switch ON or close driver side door when ignition switch is in “ACC” position.
4. The system performs ENTRY OPERATION. (Seat and steering positions are moved to memorized posi-
tions. The memorize position is related to key ID.)
Operation Condition
If the following conditions are not satisfied, memory switch operation is not performed.
Ignition switch is in OFF position.
Driver side power seat switch and door mirror control switch are not operated.
Seat memory switch and set switch are not operated.
Output malfunction is not detected.
CAN and UART communications are normal.
A/T selector lever position is in P position.
Detention position switch malfunction is not detected.
[Detention position switch malfunction is sensed when detention switch remains OFF and vehicle speed is
higher than 7 km/h (4 MPH).]
Linking Intelligent Key to the Stored Memory Procedure
NOTE:
If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.
If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.
If entry / exiting operation is cancelled, perform memory operation only.
FAIL-SAFE MODE
If any of the parts move more than a period “T” without any switch operation, MEMORY OPERATION, EXIT-
ING OPERATION, ENTRY OPERATION, INTELLIGENT KEY INTERLOCK OPERATION and the malfunction
part of manual operations are not operated (output malfunction).
Canceling Fail-safe Mode
The mode is cancelled by either of the following operations.
When the selector lever is shifted to P position from any other position (detention switch is turned OFF).

INITIALIZATION PROCEDURE
After reconnecting battery cable, perform initialization procedure A or B. If initialization has not been per-
formed, EXITING OPERATION will not operate.
Procedure A
1. Turn ignition switch from ACC to OFF position.
2. Driver door switch is ON (open) → OFF (close) → ON (open).
3. END
Procedure B
1. Drive the vehicle at more than 25 km/h (16 MPH).
2. END
SETTING CHANGE FUNCTION
The settings of the automatic driving positioner system can be changed, using CONSULT-II and the display
unit in the center of the instrument panel.
×: Applicable –: Not applicable
It is possible to set sliding driver seat for entry/exit of vehicle by pressing set switch.
CAN Communication System DescriptionNIS0025S
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0025T
Refer to LAN-50, "CAN System Specification Chart" .
