How to change 2003 Toyota Highlander seat belt?

To change the seat belt in a 2003 Toyota Highlander, first ensure the vehicle is parked with the engine off. Remove the lower mounting bolt using a socket wrench, then detach the upper anchor point, typically found near the roof or side pillar. Carefully pull the old seat belt out and replace it with the new one, securing both mounting points tightly. Finally, test the functionality of the new seat belt to ensure it retracts and latches properly.
