Honda Civic Hybrid honks horn 3 times every time I start it up?
 

I just got a Civic Hybrid recently that I love...but every time I start it up it will honk it's horn 3 times rapidly. It's not warning me about anything, as I've checked it out and nothing's out of the ordinary. I've also scoured the manual and still no answers...has anyone dealt with this before?































It's really getting annoying, because everyone thinks I'm honking at them when I'm not! I've been flipped off a few times already (I guess it's a California thing)
