I take it you mean the light strange shaped blob symbol. I had this after a couple of weeks, and it turned out just to be a loose wiring connection. Also, on my dads Fiesta Zetec the temp high warning kept coming on repeatedly when he was just setting off, again was just just an electrical fault. It could be the same for both cases with you.

But whichever, definitely take it in to your dealer to get it sorted out right away. Hopefully it won't be anything more than an electrical problem.
