Can I get sued for selling my car "as is?" I forgot to get it smogged.?

I know this is a common question asked but I believe my situation is a little different. I sold my car today and wrote a written contract that clearly states the car is sold "as is." The purchaser signed it on my written out contract. I also put sold "as is" on both copies of the bill of sale, but forgot to have the purchaser sign that. I am more than willing to pay for the car to get smogged and I'm really not worried about whether or not it will pass. However, I've been contacting him persistently saying that I'd pay for the smog check and that we could meet up tomorrow morning to have it done. He is no longer responding to my texts or phone calls. He agreed to meet me at a dealership to get the smog done in person, but after that he has failed to confirm the time of our meeting. I'm worried about getting into some sort of legal issue. I intend on bringing my release of liability to the DMV tomorrow morning as a safety precaution. What should I do to avoid any issues, because I'm clearly trying to comply with the law (that I unfortunately forgot at the time of sale)?
