Renault Lagune service light on air bag light on no speedo or revs

I used my car this morning and it was fine.

Came to use it this afternoon and it was fine



Used again 10mins later and the service light, stop light and cruise control lights were on. Plus I had no indicators, and the revs and speedo did not work.



Apart from a little grumble in the engine it drove fine, but now these lights remain on and the car seems to be not switching its management system off?

HELP!

Thanks
