Zs locks up if you take seat belt off when on a steep hill

[jon newt]

My mate has a steep driveway his wife reversed down and took off seatbelt to look out of window as rear camera was dirty. The seatbelt refused to release and the car became unresponsive and just shut down. He called mg service and the guy came and stretched the rear middle seat belt over to the drivers side plugged it in and it came back to life! He said it is an inbuilt safety measure and he has seen it before.

I guess one could plug the seatbelt in and sit infront of it ... if one really felt the need.

Turn auto hold off.

Why couldn't he just plug the drivers seatbelt back in?

Is this another mk2 "improvement"?

The seatbelt would not release so he had to plug rear one in.

Confusing.. release from what?

From where it comes out from central Pilar they would not release that’s why had to use rear centre belt .

So locked up from B Pilar almost the same as when airbags deployed after a accident?

Good to know

Both fronts? I'd have tried front passenger first...

Or like when they've pretensioned whilst braking down a hill say

It's a ball bearing that rolls forward in the reel of the belt that locks it. If you're on a steep downhill slope it makes it very difficult to release, but if you can retract the belt some it should release. Moving the seat backwards or reclining the back should allow you to do it.

I always wondered how they did that

I always wondered how they worked !
(Glad it's not had a breath of "improvement" too )

Typically they can look a bit like this inside.
Either a ball bearing in a seat, or a pendulum weight that locks a pawl, which in turn locks the belt when the weight / ball swings off centre.

well you learn something new every day, thanks for that.

Tbh I’d never thought ‘how do seatbelts work’ but it’s good to know. Thanks for sharing.
