Dirt can cause current loss and a shorter battery life. To clean the battery, you do not need to remove it. Before starting any operation, disconnect the battery.

Clean the connectors with a cleaner, then scrape off any old residue. Wash the terminals with water and then dry them.

Once the terminal cleaning is complete, reposition the cables, connecting the positive terminal first and then the negative, tightening the nuts with a wrench. After that, replace the tape covering the terminals.

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.
