The belt will automatically retract to its stowed position.
If necessary, slide the latch plate down the webbing to
allow it to retract fully.
WARNING!
A frayed or torn belt could rip apart in an accident
and leave you with no protection. Inspect the belt
system periodically, checking for cuts, frays, or loose
parts. Damaged parts must be replaced immediately.
Do not disassemble or modify the system. Seat belt
assemblies must be replaced after an accident if they
have been damaged (bent retractor, torn webbing,
etc.).
