1983 500SL RS Warning Light on Dash??

[low farm]

While testing the water tightness of the cabrio top - which was very good, the above warning light came on when engaging reverse.
No mention of it in the handbook.

Any ideas what it means?

I'd guess something to do with the seatbelt system

but I'm not even sure I have one on mine. have you an airbag fitted?

Thanks for thye reply Myros.

No airbag fitted and there are no electrical connections to the seats or belts.

Next run out will be tomorrow night, dried out now, so we can see if the warning light is still on.

Its in the warning light bar at the end below the tacho.

Will advise if we find out what it means.
