From the Harrier.ev's owner's manual:
"Seat Belt Warning Lamp
Your vehicle is equipped with Seat Belt
Reminder (SBR) for all occupants.
If the driver or any passenger do not
fasten the seat belt, seat belt reminder
lamp will blink and a buzzer will sound
for pre-defined duration until the seat-
belt is buckled
If any passenger seat is occupied by
child (without child seat), system may
detect occupancy and warn with seat
belt warning. It is not taken to mean
child can occupy any passenger seat
and use seat belt. Please refer CRS
section for recommended seating po-
sition if child is sitting with child seat.
NOTE
Whenever an occupant is not sitting
in any seating position then seat belt
reminder beeping sound will not be
played in instrument cluster.
If any material is kept on any seat
then SBR beeping sound may be
played in instrument cluster. Please
do not keep any material on seat.
NOTE
Fitment of unauthorized seat covers
on any seating position is strictly pro-
hibited. It may affect the function of
occupant sensor."
