1. Park the Lev
Find any normal parking spot in the Home Zone to park your Lev. Since you can park 3 Lev's on a spot for a single car, you shouldn't have too much trouble finding one.
2. Engage the handbrake
To turn off the engine of the Lev you have to engage the handbrake. The big handle tells you what it is in big friendly letters, so pull it tight.
3. Close windows and the roof
If you've opened up the Lev to get that nice breeze, make sure all windows and the roof are closed before you end your trip.
4. Take your stuff and close the door
Don't forget to take your stuff when you get out and close the door behind you.
5. End your trip in the Lev app
All that's left to do is end your trip in the app, and Lev locks itself.
