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

Reversal
The door will reverse direction during power open or close operation if the automatic door main switch, keyfob
or back door close switch is operated. A chime will sound to announce the reversal.
Anti-Pinch Function
• During auto operation, if an object is detected in the door's path, a warning chime sounds and the back door
operates in the reverse direction to prevent pinching.
• During auto close operation, if an object is detected by the pinch strips in the door's path, a warning chime sounds and the back door operates in the open direction until it is fully open.
Gas Stay Check
• During each power open operation, the back door control unit monitors motor current draw to determine ifthe gas stays are functioning properly.
• If a malfunction of the gas stays is detected, the back door control unit will close the back door while sound-
ing the warning chime. The back door cannot be opened usi ng the switches until the gas stay malfunction is
repaired.

same manner as the remote controller by operating the back door open button.
OPERATION DESCRIPTION/BACK DOOR OPEN FUNCTION
• When back door button of the Intelligent Key is press ed, the back door open signal is transmitted from the
Intelligent Key to the back door control unit via remote keyless entry receiver and the Intelligent Key unit.
• When back door control unit receives the back door open request signal, it operates the back door motor
and opens the liftgate.
OPERATION CONDITION
OPERATION AREA
• Operating Range
• To ensure the Intelligent Key works effectively, use within 80 cm range of each door, however the operable range may differ according to surroundings.
HAZARD AND HORN REMINDER FUNCTION
When doors are locked or unlocked by Intelligent Key. BCM flashes hazard warning lamps as a reminder and
transmits horn chirp signal to IPDM E/R. IPDM E/R sound horns as a reminder.
The hazard and horn reminder has a horn chirp m ode (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
