The following guide shows how to address the airbag warning light issue. You may need to replace the control unit and fuses.

In such cases, it may be helpful to take your car to a service centre where they will connect your vehicle to sophisticated software that can identify the reasons for the malfunction. This problem can occur frequently, likely due to the constant movement back and forth when someone is seated in the rear, causing one of the sensors located in the passenger seat to become loose.

The wire may not be connected properly or may be oxidised.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
