DOOR LOCK FUNCTION
• The door lock and unlock switch (driver side) is built into power window main switch.
• The door lock and unlock switch (passenger side) is on door trim.
• Interlocked with the locking operation of door lock and
unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors are
unlocked.
Door Key Cylinder
• With the door key inserted in the door key cylinder on driver side, turning it to “LOCK”, will lock door lock
actuator of all doors.
• With the door key inserted in the door key cylinder on driver side, turning it to “UNLOCK” onc\
e unlocks the driver side door lock actuator; turning it to “UNLOCK” again within 5 seconds after the first unlock operation
unlocks all of the other doors. - (SELECTIVE UNLOCK OPERATION)
Selective unlock operation mode can be changed usi ng “DOOR LOCK-UNLOCK SET” mode in “WORK SUP-
PORT”. Refer to DLK-52, "
DOOR LOCK : CONSULT-III Function (BCM - DOOR LOCK)".
AUTOMATIC DOOR LOCKS (LOCK OPERATION)
The automatic door locks 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.

DOOR LOCK FUNCTION
DOOR REQUEST SWITCH
DOOR REQUEST SWITCH : System DiagramINFOID:0000000003775679
DOOR REQUEST SWITCH : System DescriptionINFOID:0000000003775680
Only when pressing the request switch, it is possible
to lock and unlock the door by carrying the Intelligent
Key.
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verifica-
tion using two-way communications between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver (Warning chime function).
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn reminder func-
tion).
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
• It is possible to perform a diagnosis on the system and register an Intelligent Key with the CONSULT-III.
OPERATION DESCRIPTION/DOOR LOCK/UNLOCK
• When the BCM detects that each door request switch is pressed, it starts the outside key antenna and inside
key antenna corresponding to the pressed door request swit ch and transmits the request signal to the Intelli-
gent Key. And then, check that t he Intelligent Key is near the door.
• If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
• BCM receives the key ID signal and compares it with the registered key ID.
• BCM sends the door lock/unlock signal and sounds Intelli gent Key buzzer warning (lock: 2 times, unlock: 1
time) at the same time as a reminder.
OPERATION CONDITION
If the following conditions are not satisfied, door lock/unlock operation is not performed even if the request
switch is operated.
Door switch Transmits door open/close condition to BCM.
Passenger select unlock relay Enables or disables the unlocking of rear doors when this Intelligent Key option is selected. Item

*: 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/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver and passenger door handles (1).
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of back door lock/unlock
function is in the range of approximately 80 cm (31.50 in) surround-
ing the back door handle (1).
SELECTIVE UNLOCK FUNCTION
When a LOCK signal is sent from door request switch (driver side or passenger side), all doors will be locked.
When an UNLOCK signal is sent from door request switch (driver side or passenger side) once, driver's door
will be unlocked.
Then, if an UNLOCK signal is sent from door request switch (driver side and passenger side) again within 5
seconds, all other doors will be unlocked.
HAZARD AND BUZZER REMINDER FUNCTION
During lock or unlock operation by each request switch, the hazard warning lamps and Intelligent Key warning
buzzer will blink or honk as a reminder.
When doors are locked, unlocked by each request switch, IPDM E/R honks Intelligent Key warning buzzer as
a reminder and transmits hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder.

DOOR LOCK FUNCTION
• To ensure the Intelligent Key works effectively, us
e within 80 cm range of each doors, however the operable
range may differ according to surroundings.
SELECTIVE UNLOCK FUNCTION
When a LOCK signal is transmitted from Intelligent Key, all doors will be locked.
When an UNLOCK signal is transmitted from Inte lligent Key once, driver's door will be unlocked.
Then, if an UNLOCK signal is transmitted from Intell igent Key again within 5 seconds, all other doors will be
unlocked.
When a liftgate signal is transmitted from Intelligent Key for more than 0.5 second, the back door operates to
the full open position. After opening, another signal will cause the back door to close.
HAZARD AND HORN REMINDER FUNCTION
When doors are locked or unlocked by Intelligent Key, BCM flashes hazard warning lamps as a reminder and
sends horn chirp signal to IPDM E/R. IPDM E/R sounds horn as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
Operating function of hazard and horn reminder
Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-III
Refer to DLK-56, "
CONSULT-III Function (INTELLIGENT KEY)".
Without CONSULT-III
Refer to Owner's Manual for instructions.
AUTO DOOR LOCK FUNCTION
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF, doors
are unlocked with Intelligent Key button. When BCM does not receive the following signals within 30 seconds,
all doors are locked.
• Door switch is ON (door is opened)
• Door is locked
• Ignition switch is ON
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by DOOR LOCK -UNLOCK SET mode in “WORK SUPPORT”. Refer to
DLK-52, "
DOOR LOCK : CONSULT-III Function (BCM - DOOR LOCK)".
PANIC ALARM FUNCTION
When ignition switch is OFF (ignition switch is not pr essed) and key switch is OFF, BCM receives PANIC
ALARM signal from Intelligent Key through the remote keyless entry receiver and the Intelligent Key unit.
BCM turns on and off headlamp intermittently and transmits theft warning horn signal to IPDM E/R. Then,
IPDM E/R turns on and off horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:
• After 25 seconds
• When BCM receives any signal from Intelligent Key
Panic alarm function mode can be changed by PANIC ALARM SET mode in “WORK SUPPORT”. Refer to
DLK-56, "
CONSULT-III Function (INTELLIGENT KEY)".
KEYLESS POWER WINDOW DOWN (OPEN) FUNCTION
Front power windows (with left and right front power window anti-pinch system) open when the unlock button
on Intelligent Key is activated and kept pressed for more than 3 seconds with the ignition switch OFF. The win-
dows keep opening if the unlock button is continuously pressed.
The power window opening stops when the following operations are performed:
• When the unlock button is kept pressed more than 15 seconds.
