Insert the seat belt tongue (C) into the seat belt buckle (D) until you hear a click
sound.
Fastening the Centre-Rear Seat Belt with Only One Buckle:
Fastening the centre-rear seat belt with only one buckle is dangerous. If only one
pair of seat belt tongues and buckles is fastened (either seat belt tongue (C) and
seat belt anchor buckle (D) or seat belt tongue (A) and seat belt buckle (B)), then
the seat belt cannot provide full protection. In a sudden stop or collision, the user
could slide under the belt and suffer serious injuries. Always make sure that both
pairs of seat belt tongues and buckles are fastened properly.
