To ensure the Intelligent Key works effectively, use within 1 m (3 ft) range of each door, however the operable
range may differ according to surroundings.
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, blinks the hazard lamp (lock:
2 time, unlock: 1 times) and inputs horn chirp signal to IPDM E/R at the same time as a reminder.
 IPDM E/R honks horn (lock: 2 time) as a reminder
