AUTOMATIC DRIVE POSITIONER
Revision: August 20072004 QX56
Manual OperationEIS002Y4
The driving position [seat position, steering wheel, pedal position (accelerator, brake) and door mirror position]
can be adjusted with the power seat switch LH, pedal adjusting switch, door mirror switch or ADP steering
switch.
NOTE:
The door mirrors can be manually operated with the ignition switch turned to ACC or ON.
Only when A/T selector lever is in P position, adjusting pedal operates (except when ignition switch turned
to OFF).
If A/T device (detent switch) error is detected, manual adjustable pedal operation cannot be performed
when ignition switch turns ON.
Automatic OperationEIS002Y5
NOTE:
Disconnecting the battery erases the stored memory.
After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open)→OFF (close)→ON
(open), the Entry/ Exiting function becomes possible.
After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
System DescriptionEIS002Y6
The system automatically moves the driver seat and steering wheel to facilitate entry/exit to/from the vehi-
cle. The driver seat control unit can also store the optimum driving positions (front seat, pedal position and
door mirror position) for 2 people. One-touch operation allows changing between driving positions.

Function Description
Memory operation The seat, steering wheel, pedal (accelerator, brake) and door mirror move to the
stored driving position by pushing seat memory switch (1 or 2).
Entry/Exit-
ing functionExiting operation At exit, the seat moves backward and the steering wheel raises. (Exiting position)
Entry operationAt entry, the seat and steering wheel return from Exiting position to the previous driv-
ing position before the Exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing key-
fob unlock button.
Auto operation temporary stop
conditions.When ignition switch is turned to START during seat memory switch operation and return
operation, seat memory switch operation and return operation is stopped.
Auto operation stop conditions.
When the vehicle speed becomes 7 km/h (4 MPH) or higher (memory switch operation
and entry operation).
When the setting switch, seat memory switch 1, or 2 are pressed.
When A/T selector lever is in any position other than P.
When the door mirror switch is operated (when ignition switch turned to ON).
When power seat switch turned ON.
When pedal adjusting switch turned ON.
When front seat sliding Entry/Exiting setting is OFF (entry/exiting operation).

MEMORY OPERATION
Selecting the memorized position.
NOTE:
The front seat position and pedal adjustment functions (see the following table) operate simultaneously in the
order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.
ENTRY OPERATION
When the seat is in the exiting position, the following operation moves the seat to the previous position before
the exiting operation.
EXITING OPERATION
At Entry/Exiting, the seat is automatically moved to the exiting position.

SELF-DIAGNOSIS RESULTS
DISPLAY ITEM LIST
NOTE:
If park switch error is detected, manual adjustable pedal operation cannot be performed when ignition
switch turns ON.
The displays of CAN communication and detection switch display error detecting condition from memory
erase to the present on “TIME”.
–If error is detected in the past and present error is detected, “CRNT” is displayed.
–If error is detected in the past and present error is not detected, “PAST” is displayed.
–If error has never been detected, nothing is displayed on “TIME”.
Any items other than CAN communication and park switch count error detection frequency occurred after
erase history to “1-127”.
–If error was detected in the past, error detection frequency from memory erase to the present is displayed
on “TIME”.
–If error has never been detected, nothing is displayed on “TIME”.
–Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
Error: Clear memory in error condition, error is detected again and “1” is displayed on “TIME”.
