Take it your dealer to have them check out the SRS system, something didn't like the jump start, and you may have a damaged sensor or module.
Its best to think of the SRS systems as having "No user serviceable parts", unless you are absolutely positively without a doubt 110% certain you know what you're doing.
We have a brilliant young neighbor in our condo complex, he's a real computer expert and software designer, he's also blind for life after accidentally triggering the passenger airbag on his Subaru WRX during a stereo install.
So please take your HHR to the dealer and have them run a diagnostic on your airbags.
I was having a problem with the service air bag light coming on, having it into the delear a couple times. I got thinking about it after taking it in again and realized it was occurring after the HHR wasnt being driven over the weekend or longer. After speaking to a mechanic, we decided to try to disconnect the GPS from the lighter socket when it wasnt being driven. He said a voltage drain would cause "codes" to spit out and it did crank over slower after the disuse. Hasn't happened since.
mine shows up if i drop something on pass seat. goes out when it feels like. taking to dealer a waste unless it stays on. did that, they said no problem found. i kept the paperwork in case it causes a problem down the road. also came on after washing seats, go figure.
