Procedure:Jacking and supporting must be performed on a level surface. Never use a jack to raise a vehicle that is not on level ground, such as an inclined driveway.
Jacking points are very important. Look under the rocker panels, and look for the double-seam-welded sections. They're about 8 inches from the back of the front wheel wells, and 6 inches from the front of the rear wheel wells. You may also use the area on the front subframe where the lower transmission mount bolts up. The jack must be on one of these reinforced areas when lifting the car.
After lifting the car, you should support the car. Both sides should be supported in most situations. The acceptable jack stand locations are the reinforced areas of the rocker panels (the same locations for jacking), the rear subframe, and the rear-most mounts of the front control arms. The front subframe lifting point is unacceptable for support with a jackstand due to being off-center.
