• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors and
trunk (sedan) are locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors and
trunk (sedan) are unlocked.
Functions available by operating t he front door key cylinder switch LH
• Interlocked with the locking operation of front door key cylinder switch LH, door lock actuators of all doors
and trunk (sedan) are locked.
• When front door key cylinder switch LH is unlo cked, front door lock actuator LH is unlocked.
• When front door key cylinder switch LH is unlocked for the second time within 5 seconds after the first oper- ation, door lock actuators on all doors and trunk (sedan) are unlocked.
Key reminder door system
When door lock and unlock switch is operated to lock doors with ignition key inserted in key cylinder and any
door open, all door lock actuators are locked and then unlocked.
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed.
Vehicle Speed Sensing Auto Door Lock*1
All doors are locked when the vehicle speed reaches 24 km/h (15 MPH) or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 15 MPH (24 km/h) or more.
If a door is opened and closed at any time during one ignition cycle (OFF → ON), even after initial auto door
lock has taken place, the BCM will relock all doors when the vehicle speed reaches 15 MPH (24 km/h) or more
again.
Setting change of Automatic Door Locks (LOCK) Function
The lock operation setting of the autom atic door locks function can be changed.
With CONSULT-III
The ON/OFF switching of the automatic door locks (LOC K) function and the type selection of the automatic
door locks (LOCK) function can be performed at the WO RK SUPPORT setting of CONSULT-III. Refer to BL-
41, "CONSULT-III Function (BCM)".
Without CONSULT- III
The automatic door locks (LOCK) function can be swit ched ON/OFF by performing the following operation.
1. Close all doors (door switch OFF).
2. Turn ignition switch ON.
3. Within 20 seconds of turning the ignition switch ON, press and hold the door lock and unlock switch to the LOCK position for more than 5 seconds.
4. The switching is completed when the hazard lamps blink.
5. The ignition switch must be turned OFF and ON again between each setting change.
OFF → ON : 2 blinks
ON → OFF : 1 blink

Operation Description
• When the Intelligent Key unit detects that each request sw
itch is pressed, it starts the outside key antenna
and inside key antenna corresponding to the pressed request switch and sends the request signal to the
Intelligent Key. And then, make sure that the Intelligent Key is near door.
• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and sends the key ID signal to the Intelligent Key unit.
• Intelligent Key unit receives the key ID signal and compares it with the registered key ID.
• If the key ID check result is OK, the Intelligent Ke y unit sends the door lock/unlock request signal to BCM
(Body control module) via CAN communication line.
• Intelligent Key unit sends the door lock/unlock signal and sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it oper ates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
If the following conditions are not satisfied, door lock/unlock operations are not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as Key IDs are different.
Outside Key Antenna Detection Area
The outside key antenna detection area of door lock/unloc k function is in the range of approximately 80 cm
(31.50 in) surrounding the request switch (driver side, passenger side and back door or trunk area).
Hazard and Buzzer Reminder
When all doors and trunk (sedan) are locked or unlocked by each request switch, Intelligent Key\
unit sends
hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer(s) as a reminder.
Operating function of hazard and buzzer reminder
* : Sedan only
Auto Door Lock Function
When all doors and trunk (sedan) are locked, ignition knob sw itch is OFF (when ignition switch is not pressed)
and key switch is OFF (when mechanical key is out of ignition key cylinder), all doors are unlocked with each
request switch.
When Intelligent Key unit does not receive the following signals within 1 minute, all doors are locked.
• Door switch is ON (door is opened)
• Trunk lamp switch (sedan) is ON (trunk is opened)
• Door lock signal from Intelligent Key button
• Ignition knob switch is ON (ignition switch is pressed)
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
117, "CONSULT-III Application Item".
