Slowly, without breakthroughs, extend a belt and implant a uvula into the lock before click (check reliability of fixing of a belt in the lock, having pulled for a uvula). If at a pulling of a belt the blocking mechanism works, weaken a tension of a belt and then continue to extend smoothly.

If the belt is not extended:

– slowly, but strongly pull a belt, having extended it approximately on 3 cm;

– then release a belt that it was automatically involved in the pulling device;

– again extend a belt;

– if the belt is still not extended, address on the service station Renault.
