Having had a few Scenic's it is about the same as the current model (not the grand scenic though) if that helps as a rough guide. You can find these on any car sales site or the Renault UK web site.
Otherwise someone who has one of that ilk will have to get their little book out of the glove box!
A rough guide should only be a problem if you don't order enough liquid to fill it !!!!!!!!!!!!!!!! :d
