To the right.
When parking downhill, whether there is a curb or not, always point your wheels toward the curb or the edge of the road. This way, if the vehicle begins to roll, it will be directed toward the curb, preventing it from rolling into traffic. If there is no curb, turn the wheels toward the roadside to minimize the risk of your vehicle rolling into the path of other vehicles.
Toward the shoulder. If you are parked on the right side of the road.

No more than it would harm parking it facing downhill. Makes no difference really. Just make very certain that you do these things when parking:* always point the wheels away from the curb when facing uphill * always point the wheels toward the curb when facing downhill * always set the parking brake while your foot is on the brake and BEFORE putting into Park on automatic transmissions. Applying the parking brake should be done every time regardless of the terrain. If one gets into the habit of doing this all the time, then it will become automatic. The little pin in the transmission is all that is holding the car from rolling ... use the brake, too. It will help greatly when you are trying to get the transmission out of Park when on a hill if the parking brake has not been used.Manual transmission people always use the parking brake (handbrake) anyway, so it is something we do without thinking. A good habit for everyone.
Wheel chocks are an important safety measure to keep the car from rolling while you are working on it, should the parking brake fail or not be set. In addition, many cars only have parking brakes on the rear wheels, and it can be necessary to chock the front wheels in order to jack up the rear of the car.
If you are parked on level ground or facing downhill, you should turn your wheel towards the curb, so that the front of the tire is facing the curb. This way, if your car begins to roll down the hill or is struck from behind, it will be forced into the curb. If you are parked facing up a hill, you should turn your wheel away from the curb, so that the back of the tire is facing the curb. This way, if your car begins to roll down the hill, it will be forced to stop on the curb. Always apply your parking brake when parking on a hill.
