How many miles/how old is your car? Check tire pressure and set it to at least 42psi when tires are cold. Navigate to your destination and the car will direct you to superchargers as needed. Stop as directed, perhaps add a few percent for just-in-case (usually wind) and you should be fine. The car should have come with an adapter to change from J1772 style of plug (non-Tesla standard plug) to the Tesla style. If you have a mobile charger, be sure it is in the car. (If not, consider buying one). When you are doing your last charge before your destination, be sure you end up with enough charge to do something the next day, unless you are staying at a place with overnight charging.
