You can hear the Bolt engage its locking mechanism while holding the charge cord handle so you know when it's engaged. I didn't try their method in the video, but held the handle firmly against the port so it was flush and had the app ready to swipe on the phone in the other hand. It engages pretty quick after swiping. But one item they didn't mention, is make sure you pull as far forward as possible so the cable comfortably reaches the car's charging port. On my first attempts, I actually supported the cable with a sleeping bag, but later determined that was unnecessary once the Bolt had engaged its locking mechanism.
