The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button.
OPERATION DESCRIPTION/DOOR LOCK/UNLOCK FUNCTION
• When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is transmitted
from Intelligent Key to BCM via remote keyless entry receiver.
• When BCM receives the door lock/unlock signal, it operates door lock actuator, flashes the hazard lamp
(lock: 2 times, unlock: 1 time) and horn chirp signal to IPDM E/R at the same time as a reminder.
• IPDM E/R honks horn (lock: 1 time) as a reminder.

• To ensure the Intelligent Key works effectively, use within 80 cm (31.50 inch) range of each doors, however
the operable range may differ according to surroundings. The remote control operation range is greater than
that of the Intelligent Key. Refer to Owner's Manual for more details.
SELECTIVE UNLOCK FUNCTION

unlocked.
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).
