Donald's got it spot on. Treat it as a one-off and keep your fingers crossed that this is the end of the matter. Any decent Renault dealer will tell you to do the same, though no doubt one or two would welcome the opportunity to charge you an hour's labour and then tell you there's nothing wrong with it.
It sounds like the dash computer has crashed for some reason. The processor has stalled, so the watchdog timer has kicked in and forced a reset. It has dealt with the situation exactly how it should have done. As for why it crashed in the first place - like most computer crashes, you'll probably never know.
Even if it does get worse (say it starts happening once a week) Renault will want to sting you about 500 quid for a new instrument cluster. On a ten year old car, I'd be inclined to just live with it.
