Using a hydraulic car jack safely involves a precise sequence of steps to prevent injury and vehicle damage. The core process is to always park on a level, solid surface, engage the parking brake, and chock the wheels opposite the jacking point. The most critical step is locating the vehicle's designated jack points, which are reinforced metal seams or pads on the frame, not the rocker panels or floorboards. Consult your owner's manual for their exact location.
Begin by ensuring the jack's release valve is fully closed by turning it clockwise. Position the jack saddle directly under the correct jack point. Operate the jack handle with smooth, steady pumps until the saddle makes contact. Double-check the alignment before lifting the vehicle just high enough to perform your task; the tire should only clear the ground by an inch or two. Never place any part of your body under a vehicle supported only by a jack. Always use jack stands as a secondary, redundant safety support before working under the car.
To lower the vehicle, slowly turn the release valve counterclockwise. Do this gradually and ensure the area is clear.
| Critical Safety Check | Correct Action | Common Mistake to Avoid |
|---|
| Surface Stability | Park on solid, level pavement like concrete. | Jacking on gravel, dirt, or a slope. |
| Wheel Security | Chock wheels and engage parking brake. | Relying only on the transmission's 'Park' mode. |
| Jack Point Identification | Lift only at manufacturer-specified metal points. | Jacking under the oil pan, axle, or body panels. |
| Vehicle Height | Lift only until the tire clears the ground minimally. | Lifting the vehicle excessively high. |
| Secondary Support | Always use jack stands under the vehicle's frame. | Working under a car supported only by the jack. |
