AUTOMATIC DRIVE POSITIONER
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.
FA I L - S A F E M O D E
When any manual and automatic operations are not performed, if any motor operations of seats or pedals are
detected for T2 or more, status is judged “Output error”.
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the A/T selector lever is shifted to P position from any other position.
NOTE:
The front seat LH 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.Function Description
Memory operation The front seat LH, steering wheel, pedals (accelerator, brake) and door mirrors 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 driving
position before the exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing keyfob
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 remote control 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).

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”.
