Hi hope this doesn,t sound stupid but if I take my battery off to clean under it will I have to reset any thing will I get any warning lights on the dash any information will be welcome

If you put everything back properly you shouldn't get any warnings. You'll only have to reset the date and time, and probably have to re save all your radio stations again.

If you have the skywindow sunroof it may need resetting (most don't).
You may need the radio code (most don't unless you have an aftermarket coded radio)
