How do you remove headliner on 2003 Hyundai Santa Fe?

To remove the headliner from a 2003 Hyundai Santa Fe, start by removing any trim pieces, such as the A, B, and C pillar covers, and any grab handles or sun visors. Carefully detach the headliner from the adhesive or clips holding it in place, being mindful of any wiring for lights or sensors. Once loose, gently lower the headliner and slide it out through the rear of the vehicle. Ensure you have assistance if needed, as the headliner can be cumbersome to maneuver.
