00 00 ... Seat belts: checking condition of belt strap, function of inertia reel mechanism, locking reel, belt buckle

WARNING: This page is about a different car, the 2007 BMW 550i and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

Belt strap, retractor mechanism, belt interlock

Pull out strap and make sure it emerges without jerking.

Check belt strap for

folding
unravelling
pinches
cracks and tears
traces of melting

Retract belt strap; here the inertia reel mechanism must retract the strap automatically and without squeaking noises, the last section of the strap may have to be fed in.

Pull out belt strap in short tugs - locking reel must lock.

Belt buckle

The tongue on the belt strap must easily snap into place with an audible click.

When the "Press" button is pressed, the tongue must be ejected from the buckle under spring pressure.
