Chevy Volt manual trunk release tool

There's a 5/16" square drive manual release for the trunk hatch on your Gen 2 Chevy Volt. If your battery dies, you need to crawl into the back of the car, and open the hatch to change/jump the battery, because Chevy couldn't put it the engine bay like a normal car. They could have at least given you a jump point under the hood like a BWM. Sigh...

Print it, keep it in your glove box.
