Hello I'm looking for advice.  Have a 2007 pontiac g6 gt. I worry about the top malfunctioning and I want to do as much prevention as possible. I have the oil for the pump I haven't tried to add any extra oil. So far the top has been working fine.  

If your top doesn't come up is there a manual way to bring it up?

Unfortunately there is no provision to operate the top manually. So much so that if the top is in between full up & full down the vehicle must towed by flatbed & must be facing backwards to prevent a lift effect resulting in damage.

Thank you for this information.

One other known weakness  in the G6 GT convertible is there is a sensor switch that can fail. The problem is GM discontinued this sensor switch almost a decade ago and there is absolutely no NOS parts left. You're only hope is to find a used one off another wrecked / parted out G6 convertible. Even though GM produced flip-top hardtops in the Cadillac XLR and Chevy SSR during this same time frame, this sensor switch is unique to just the G6.

I will say this about your top question! Not always, but more the rule than not, there is usually more that one way to skin a cat as they say! So while I do not the the top & it’s mechanisms very well I would say there is a way to lower or raise the top with out power! And the switch that Frosty speaks of might be able to be changed to another type of device. 
Presuming this to be true now would be a good time, before a failure, to determine what those two things might be. For example, the top has to have some type of scissor arrangement. That must be connected in some manner to a drive of some kind. Disconnecting that drive & or it’s components might release the top to enable it to be moved manually, give you have the right force. For example, a small 12v gear drive with the right connection or a simple breaker  bar with the right interface connection & the right leverage. The sensor might be able to be replaced with micro switches that would need brackets made & attached in proper locations + whatever wiring that would require. 
 

Hopefully you see the point here! If you plan to keep the car long term now is the time to figure out what those things need to be or start acquiring the needed parts to replace bad ones if you can.

My two cents!
