Lift the car high enough so that you can fit the jack stand beneath the car next to the jack. Be sure the jack stand is centered beneath the frame, so that when the car is lowered it will sit evenly on the jack stand.

Slowly lower the jack so that the frame of the car is resting securely on the jack stand.

Continue lowering the jack in order to remove it from under the car.

Never work underneath a car that is resting only on a jack. The jack can slip or fail resulting in serious injury.
