The TPMS on the Ford Fiesta operates using a direct system: this means that each wheel is equipped with a sensor mounted inside the tyre and fixed to the valve stem. These sensors constantly measure the pressure and temperature of the air inside each tyre and send the data in real-time to the onboard computer, allowing you to view the pressure values of each individual tyre on the dashboard display.

The system communicates with a warning light shaped like a section of a tyre. If it stays illuminated, at least one of the tyres has a pressure lower than recommended.

If it flashes on startup and then remains lit, the TPMS is faulty; if it turns on and off while driving, the pressure is close to the warning threshold.

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.
