The pollen filter purifies the air in the cabin, preventing allergies for sensitive individuals. The filter is located in the engine compartment under the windscreen.

Obtain a pollen filter identical to the original model. To access it, rotate the three clips of the air grille approximately ¼ turn.

Remove the cover by lifting it. Once the filter cover is off, take out the filter from its housing by unscrewing the two side screws with a ratchet and then carefully pulling it upwards to avoid dispersing dust. Clean the housing from any dirt.

Place the new cartridge into the container, ensuring it is oriented correctly, and close the cover with the clips. Unscrew the screws of the air box, lift the cover to remove the old cartridge, and insert the new cartridge.

Close the air box securely with its screws.

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.
