Cars are definitely one of the more rare items to find in DayZ. They're also a lot of work as you need to get all the parts together in order to even use them. So, you've gotten your car compiled and you're ready to drive. It's worth noting that these vehicles aren't tough and they're glitchy. Be careful and use high levels of caution as either you, or your car will die.
I say this as so many objects can cause problems if hit, there are disconnections and crashes too. To start you'll enter on the driver side, you'll open the car door. It's worth noting that some functionality only works in the first person. To start, just open the door and sit down. You will then need to close your door with "X", or leave it open I suppose as the choice is up to you.
You'll then need to hold "RT" on Xbox One to get the engine going, this will take a few seconds. From there you're able to start driving. If you're getting into the passenger side you can also move the seat back before getting in, this will allow others to enter into the back. Once entered, they can close fold out the seat again, or you can.
Enter the vehicle to enjoy shotgun, close the door as well. At any point you can look into what your car as within the inventory. To edit what's in it, you'll need to open the hood at the front. I hope this has assisted you with generally getting the car running, as well as general tips for handling the ride. I'll also mention that it's fun to switch perspectives once inside.
