depending on where the tree is car is located at, it is best to try not to move as much, unless you are extremely sure you are able to get out without falling off a cliff or something. If you are not sure that you can make it out, try to contact 9-1-1 and tell them your location and whats the trouble. After your call, just wait until reinforcements arrive, excuse me i meant rescue lol
hope this helps XD
