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

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).
