If none of the doors or liftgate is opened or the ignition key is not inserted in the ignition switch within 30 seconds after the doors and liftgate are unlocked using the transmitter, the ETACS-ECU will relock the doors and liftgate automatically. This is called "Timer lock function." This timer lock function prevents accidental unlocking of doors and the liftgate. The adjustment function allows you to change the timer lock period from 30 seconds (default setting) to 60, 120 or 180 seconds. For further details on using the multi-center display (middle grade type) to adjust the timer lock period, see ON-VEHICLE SERVICE .

NOTE: The timer lock period begins when the doors and liftgate are unlocked, and ends when the doors and liftgate is relocked automatically.
