Not a button? Just a light I think.
If you open the passenger door, insert the key in the slot on the A-pillar and turn it, then this light will illuminate to tell you that the passenger airbag is disabled.

I always thought that was the passenger seat ejection button :roll:
3.0si roadster. Requisite stubby. Sound gen mod. LED numberplate lights. LED boot strip. Interior lights LED too. ZHP gearknob. Daily drive :driving:
Motor in boot. Bilstein B8 dampers. New radio, much better sounds :thumbsup:

It’s the airbag light. Not on all models, my Z4M doesn’t have it.

It’s only on the lower powered 321bhp variants

As far as i know the S54 in the Z4M has always been around the 338BHP. The only car that 321BHP was the E36 M3 EVO variant, i'm guessing the S50 engine

Oh I assumed it was a sly dig at standard 3.0i owners and the 3 and 2 were round the wrong way.
Anyway, my mere 231bhp 3.0i has this facility fitted, but I've not seen it on any other models yet.

I think it may have become standard in the UK some time in 2007 as all the later facelifts seem to have it - my 57 plate 1 Series did too.
