When raising the car with a floor jack, position the jack under the crossmember at the front of the car or under the differential case of the rear axle at the rear. When jacking at the front of the car, do not position the jack under the gravel shield or the engine oil pan, or you will damage these components.
If jacking the car on an incline or high up to a steep angle, block the opposing wheels to prevent the car from rolling.
NEVER crawl under a car supported only by a floor jack; use jackstands. Do not position the jackstands under lower control arms or other slanted surfaces as they might slip and allow the car to fall. The jackstands can be placed beneath the rear axle tubes at the rear of the car, and beneath the reinforced areas of the rocker panels or front frame members. The car's weight should push vertically (downward) on the stands; the stands should be on a level and solid base.
