What safety measures should be taken before lifting the vehicle with a jack stand?

1. Correct answer: You should prevent vehicle movement (by putting on the hand brake and placing blocks under the wheels) and loosen wheel retaining/screw nuts.
2. You should verify that the vehicle stands on a straight and horizontal surface.
3. You should shift the gear handle to neutral and release the parking brake.
4. You should first lift the vehicle from another corner, to verify that the jack stand is functioning properly.
