1-4. Theft deterrent system
■ Alarm-operated door lock
In the following cases, depending on the sit-
uation, the door may automatically lock to
prevent improper entry into the vehicle:
● When a person remaining in the vehicle
unlocks the door and the alarm is acti-
vated.
● While the alarm is activated, a person
remaining in the vehicle unlocks the door.
● When recharging or replacing the bat-
tery
If a door is unlocked with the mechani-
cal key while the alarm is being set, the
pre-alarm will sound for 10 seconds.
If either the door is locked again or the
pre-alarm is stopped within those 10
seconds, an alarm will sound.
Do any of the following in order to
deactivate or stop the pre-alarm:

Close the doors, and lock all doors
by smart access system or wireless
remote control.
 Turn the engine switch to ACC or
ON, or start the engine. (The alarm
will be deactivated or stopped after
a few seconds.)
