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.
