AUTOMATIC DRIVE POSITIONER

AUTOMATIC DRIVE POSITIONERPFP:28491
System Description BIS0012G

The system automatically moves the driver seat to facilitate entry/exit to/from the vehicle. The automatic
drive positioner control unit can also store the optimum driving positions (driver seat) for 2 people. If the
driver is changes, one-touch operation allows changing to the other driving position.

Using CONSULT-II, the seat slide amount at entry/exit setting can be changed.
MANUAL OPERATION
The driving position (seat position) can be adjusted with the power seat switch.
NOTE:
The seat can be manually operated with the ignition switch OFF.
A U T O M AT I C O P E R AT I O N
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the driver door switch ON (open)→OFF (close)→ON
(open), the Entry/ Exiting operation becomes possible.

After exiting operation is carried out, entry 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.Function Description
Memory switch operation The seat move to the stored driving position by pushing memory switch (1 or 2).
Entry/Exiting functionExiting operation At exit, the seat moves backward.
Entry operation At entry, the seat returns from the exiting position to the previous driving position.
Keyfob interlock operation Perform memory operation and exiting operation by pressing keyfob unlock button.
Auto operation temporary stop
conditions.When ignition switch turned to START during memory switch operation and return opera-
tion, memory switch operation and entry operation is stopped.
Auto operation stop conditions.

When the vehicle speed becomes 7 km/h (4 MPH) or higher.

When the setting switch, memory switch 1, or 2 are pressed.

When A/T or CVT selector lever is in any position other than P.

When power seat switch turned ON.

When driver seat sliding Entry/Exiting setting is OFF (only entry/exiting operation).
