When you first exit the car look for a large rock and chock the wheel diagonal to the flat. Remove the jack, wooden board, pipe, wrench and spare tire from your trunk. Using the flat end of the wrench pry off the wheel cover and put it aside. Place the pipe over the flat end of the wrench for leverage and loosen all the nuts one turn. Unless you have been fortunate enough to park on concrete you will need to set the jack up on the piece of board.
All vehicles have what is known as a jacking point.
This is a area under the fender or side of your vehicle that the notch on your jack will fit into. It is important to find this notch since this area is designated as the best place to hold the weight of you vehicle while you change a tire. If you are unsure where yours is or cannot find it after looking your owners manual should tell you where it is located. Place the base of your jack on the board then place the jacking mechanism inside the base of the jack. Then place the jack handle in the groove or if you do not have a jack handle, remove the pipe from the flat end of the lug wrench and place the flat side in the groove.
