CAUTION
• The system does not actually detect
objects or people in the rear seat. By
using a rear door opened and closed
history, the system indicates that
there may be something in the rear
seat.
• The rear door opened and closed
history can be initialized only when
you turn off the engine normally, get
off the vehicle and lock the door with
the remote control key. Therefore,
there could be alarms even though
the back doors are locked.
e

x) When you get in and drive your
vehicle without locking the doors after
the alarm sounds, there could be the
alarm sounds if you turn off the engine
and open the driver’s seat door.
