Rear Occupant Alert (ROA)
System
The Rear Occupant Alert (ROA) system
is provided to help prevent exiting the
vehicle with the rear passenger left in the
vehicle. When you open the front door
after opening and closing the rear door
and turning off the engine, the “Check
rear seats” warning message appears on
the cluster.

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 will be initialized only when
the doors are locked after turning off
the engine. Therefore, there could be
alarms even though the back doors
are locked.
ex) 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.
WARNING
It does not use the actual sensors but it
provides the alarm sounds by checking
the rear door lock/unlock status as a
reminder.
