If you mean the limp mode after he put some fuel in the tank, then disconnect the negative battery cable in the spare tire storage area under the back floor for 20 to 30 minutes to reset the computers

As Oldblue pointed out, disconnecting the NEGATIVE battery cable will clear any stored OBD II diagnostic codes, but it's a double edged sword.
I'd limp it gently to an auto parts store to have them "Pull the Codes", it's free and easy, then post up any code numbers that will show on the printout that you're given.
Say a P0010 just as an example, that way we can get an idea if your Hubby's inattention to the fuel gauge was the cause of your HHR going into "Limp Mode", or if you've got another issue besides.
If you clear the codes before having them read, a preexisting problem can be masked until you've driven X number of miles, or you've started your HHR X number of times, then the Limp Mode might come back.

That may be the culprit Cena, after the new part is fitted, follow the Battery Disconnect info given by Oldblue, in the HHR community it's called "Giving it a Lobotomy".
You may notice your HHR drives differently for a few days, as the Lobotomy will also put the vehicle into "Learn Down Mode" where it relearns your driving style and does all sorts of high tech stuff like adjusting fuel trims, etc.
Usually in Learn Down Mode, HHR's feel a bit sluggish or brain dead until they get used to your particular driving style, from mild to wild.

Cena,
If your gonna become a mechanic to do the maintenance on your buggy I strongly suggest you get a vehicle code reader of your very own.
You can get an ELM 327 module and use your smartphone or tablet {my laptop has Bluetooth in it so I use that mostly} for as little as $7.00.
There are other really nice code readers available too. I have a nice big one I carry in my car and have a smaller one in the wife's car.
Once you have a code reader of your own you can post the codes here and we can help you more. Just think you can pull codes for your friends and get them to go online to get help fixing their cars. Just think you can buy millions of dollars in tools and open your own shop and be raking in hundreds of dollars doing automotive repair,...
{sometimes I get a little carried away but I don't let that stop me much}
Seriously having a code reader is a good thing, it really helps when you can come here with the codes.

Having your own code reader/code reader App can be a money and time saver for sure, but sometimes having the code is just the beginning.
Our own Technical Moderator donbrew, who has diagnostic skills that make him something like "The HHR Whisperer", had the code, the tools, the manuals, and the requisite skills.
And he still spent some time chasing his own tail when a code that should have been a simple replacement of Part #X, actually turned into replacing Part #Y, by the time he'd sussed everything out.
You've probably noticed by now, that when a member says I've got "Code XXXXX", those of us gray haired veterans will cage our answers by saying "it could be" or "most likely you're dealing with", rather than setting our answers in concrete.
HHR's are wily opponents when they get it into their minds to act up, some of us enjoy the challenging diagnostic puzzles, other folks are driven to frothing at the mouth in frustration.
Of course, back in my "Mechanic days" when I was working at a Firestone Tire Store/Full Service Auto Center, they gave me the Triumphs, MGs, and anything else Furrin'..."Cause Mike's one of them patient guys, he likes figuring out them pieces of junk".
