Using seat belts :

Check the condition of all seat belts regularly.

Keep the seat belts clean.

Avoid allowing any foreign bodies or fluids to get on to the seat belt or latch plate or into the slot for the seat belt buckle.

Do not trap or damage the seat belt and latch plate, for example when closing the door.

Never remove, modify or repair the seat belt or any part of the belt fixture system.

Always fasten the seat belt correctly before every journey and keep it fastened while the vehicle is in motion.
Twisted seat belt
If it is difficult to remove the seat belt from the belt guide, the seat belt may have become twisted if it was returned too quickly into the side trim:
Fasten the seat belt even if you are unable to undo the twist. However, the twist should not be in part of the seat belt that comes into direct contact with the body. The twist should be corrected immediately by a qualified workshop.
