 When exiting, 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.
 The seat slide amount and the steering oper ation at entry/exit operation can be changed.
NOTE:
 This function is set to ON before delivery (initial setting).
 Further information for the system setting procedure. Refer to ADP-54, "

OPERATION PROCEDURE
1. Shift position P position.
2. Open the driver door with ignition switch in OFF position.
3. Driver seat and steering column will move to the exiting position.

1 Ignition switch — Driver seat control unit receives the signals of [ignition switch signal]
from BCM via CAN communication.
2— Motors
(Sliding, tilt)Driver side control unit operates the sliding motor when the operating
conditions are satisfied and requests the operations of tilt motor to
automatic drive positioner control unit via UART communication. The
automatic drive positioner operates each motor.
3 Sensors
(Sliding, tilt) —Each sensor monitors the operating positions of seat and steering,
and then stops the operation of each motor when each part reaches
the recorded address.

INTELLIGENT KEY INTERLOCK FUNCTION : System Diagram
INFOID:0000000006248313
INTELLIGENT KEY INTERLOCK F UNCTION : System DescriptionINFOID:0000000006248314
 By associating Intelligent Key and automatic drive po sitioner system, the unlock operation of Intelligent Key
or driver side door request switch performs me mory function and entry/exit assist function.
 Registration of Intelligent Key interlock function can regist er a different key ID to the driver seat control unit,
one by one, for memory switch 1 and 2. A total of 2 key IDs can be registered.
 When ignition switch is OFF (steering lock unit status ), and door unlock operation is performed using Intelli-
gent Key or driver side door request swit ch, driver seat automatically adjusts to a driving position other than
seat sliding. Seat sliding and steering column tilt perform return operation and are set to standby status.
 In standby status, when ignition switch is operated from OFF to ACC, return operation sets seat sliding and
steering column tilt to a registered position.
NOTE:
 When another key ID is newly registered to a key switch to which a key ID is already registered, the previ-
ously registered key ID is overwritten and becomes unusable.
 When starter signal turns ON during return operation, the operation is interrupted, starter signal turns from
ON to OFF, and operation restarts.
OPERATION PROCEDURE
1. Unlock driver door by Intelligent Key or driver side door request switch.
2. Operation other than memory functi on of seat sliding is performed. Seat sliding and steering column tilt
perform exit assist operation.
3. Turn ignition switch ACC.
4. Driver seat and steering column will return from the exiting position to entry position.
NOTE:
Further information for Intelligent Key interlock function. Refer to ADP-54, "
INTELLIGENT KEY INTERLOCK
STORING : Description".
OPERATION CONDITION
Satisfy all of the following items. The Intelligent Key interlock function is not performed if these items are not
satisfied.
