System DescriptionEIS0 01 R6
OUTLINE
Power door lock system with super lock and key reminder is controlled by time control unit. Super lock has a
higher anti-theft performance than conventional power door lock systems.
When super lock is in released condition, lock knob operation locks or unlocks door.
When super lock is in set condition, lock knob operation cannot lock nor unlock door.
OPERATION
Power door lock/unlock and super lock set/release operation by door key cylinder
lWith the key inserted into driver door key cylinder, turning it to LOCK will lock all doors and set super lock.
(Super lock will not be set while key is inserted in the ignition key cylinder.)
lWith the key inserted into driver door key cylinder, turning it to UNLOCK will unlock all doors and release
super lock.
Power door lock/unlock and super lock set/release operation by multi-remote controller (If
equipped)
lPressing multi-remote controller LOCK button will lock all doors and set super lock. (Super lock will not be
set while key is inserted in the ignition key cylinder.)
lPressing multi-remote controller UNLOCK button once will unlock driver door and release super lock.
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
Power door lock and super lock release operation (by NATS IMMU signal)
lWhen the super lock is set, turning the ignition key switch to ON will release the super lock. All doors will
unlock once, but then immediately lock again.
Power door lock/unlock operation by lock/unlock switch
lWith lock/unlock switch on driver door trim setting to LOCK will lock all doors.
lWith lock/unlock switch on driver door trim setting to UNLOCK will unlock all doors.
