Can't help mate, but I can honestly say that the seatbelts in this thing really (annoy) me off.
The belts in my XF ute were heaps better than these pieces of shite.
Constantly caught in the door, getting caught in the door mech......I have cleaned em, lubed em, and still the same....they do NOT retract.
Should be fun in a crash....

I would by OEM and replace them, but I understand new ones are just as shiteful.
There has to be an aftermarket replacement...better get off my clacker and find one.
Any suggestions from the more informed?
