From the Thar Roxx's owner's manual:
"2.3.8 Passenger Occupant Detection System (PODS) & Seat Belt Reminder Indication
PODS detects the presence of occupant in the front passenger and on all rear seating locations.
If Occupant is present on front passenger and any of the rear passenger seats and not wearing the seat belt, Seat belt reminder warning symbol lamp will glow on the vehicle instrument cluster panel and will be continuous until the seat belt is buckled. It should be noted that the PODS require a minimum weight hence children may not be detected by PODS. Along with this warning symbol, a Chime in Cluster will be ON for 95 seconds for front seat belt reminder and 60 seconds for rear passenger seat belt reminder. Do keep in mind that after market seat covers also may deteriorate the occupant detection senor performance, don’t use the non recommended/non authorized seat covers."
