Quick Answer: To properly use a car jack, park on flat ground, chock the opposite wheels, place the jack on a reinforced jack point, raise the vehicle slowly, and support it with jack stands before working underneath. Never rely on the jack alone.
A car jack looks simple, but small mistakes with jack placement, ground stability, or lifting speed are a common cause of slips, dropped vehicles, and driveway injuries. This guide walks through how to properly use a car jack from start to finish, including jack point selection, safe lifting technique, and when a jack alone is not enough.

What Does It Mean to Properly Use a Car Jack?
Using a car jack properly means more than pumping a handle until the wheel leaves the ground. It means choosing flat, stable ground, finding the correct reinforced jack point on the vehicle’s frame, keeping the load centered, and always backing the jack up with a second layer of support, such as jack stands, before any part of your body goes under the car. A jack is designed to lift a vehicle, not to hold it in place while you work.
Many drivers only touch a jack during a roadside tire change, so the process feels unfamiliar every time. Learning how to properly use a car jack once, and practicing it in a low-pressure setting like your own driveway, makes a roadside flat tire far less stressful and far safer.
Why Proper Car Jack Use Matters for Every Driver
A vehicle can weigh well over a ton, and most of that weight sits close to the ground. When a jack is placed incorrectly, or the vehicle is not supported after lifting, the car can shift, roll, or drop with very little warning. This is why proper car jack use is treated as a core safety skill rather than a minor mechanical detail.
Beyond safety, using a car jack the right way also protects the vehicle itself. Jacking at the wrong point can dent rocker panels, crack plastic underbody trim, or damage the fuel tank or exhaust system on some vehicles. Taking a few extra minutes to use a car jack properly is almost always faster than dealing with the damage or injury caused by rushing.
Common Types of Car Jacks
Most vehicles come with a factory scissor jack, but many home garages also use a hydraulic floor jack or a bottle jack. Each type has a different footprint, lift height, and level of stability, which affects how it should be used.
Finding the Correct Jack Point on Your Vehicle
Every vehicle has reinforced jack points built into the frame or unibody, usually marked with a small notch or arrow near the rocker panel, just behind the front wheel or just ahead of the rear wheel. These points are designed to handle the concentrated weight of a jack lift. Placing a jack anywhere else, such as on the floor pan, exhaust, or plastic trim, risks bending the body or having the jack slip out from under the vehicle.
Your owner’s manual shows the exact jack point locations and often includes a diagram. If the manual is missing, many manufacturers publish this information online, or a dealership parts department can confirm it in a few minutes.
Safe-Use Decision Path
Practical guide: treat this as a pre-lift routine every time, even for a quick roadside change.
Tip: Keep a small piece of plywood or a rubber mat in your trunk. Placing it under the jack on soft ground, gravel, or asphalt in warm weather can help stop the jack base from sinking as you lift.
Step-by-Step: How to Properly Use a Car Jack
Once you have confirmed flat ground and the correct jack point, follow this sequence every time you use a car jack. Going in order matters just as much as each individual step.
Park on flat, level ground and apply the parking brake. Turn off the engine before you touch the jack.
Place wheel chocks on the wheels diagonally opposite the one you are lifting, so the car cannot roll.
Loosen the lug nuts slightly on the wheel you plan to remove, while the tire is still on the ground for resistance.
Position the jack under the correct reinforced jack point, making sure the saddle sits flush and centered, not at an angle.
Raise the vehicle slowly, pausing to check that the jack stays vertical and the vehicle is not shifting to one side.
Once the wheel is off the ground, slide a jack stand under a nearby frame point and lower the vehicle slightly onto it before working underneath.
When finished, raise the vehicle slightly off the stand, remove the stand, then lower the jack slowly and evenly.
Heads-Up: Double-check that the jack’s release valve or lowering lever is fully closed before you start pumping. A partially open valve is a common reason a jack will not hold its lift.
Safety and Electrical-Risk-Free, But Still Serious Considerations
Unlike jump starters, a car jack does not carry electrical risk, but the mechanical risk is significant. Never place any part of your body under a vehicle supported only by a jack. Never work under a car on a slope, on soft grass, or on gravel. If the vehicle shifts even slightly while unsupported, there may not be time to react.
If you have passengers, ask them to exit the vehicle before you jack it up, since shifting weight can affect balance. Keep pets and children away from the work area entirely while the car is raised.
Safety Note: A jack lifts a vehicle; it is not designed to hold that weight indefinitely. Always transfer the load to jack stands rated for your vehicle’s weight before doing any work underneath.

Best Practices vs Less-Effective Habits
Pre-Lift Checklist Dashboard
Practical guide: run through this checklist before every lift, even for jobs you’ve done before.
Matching Jack Capacity to Vehicle Type
Not every jack suits every vehicle. A small scissor jack designed for a compact car will struggle with the weight of a full-size SUV or pickup truck, and using an undersized jack increases the chance of it failing mid-lift.
Jacking Safety Priorities
Typical priority: treat ground stability, jack point accuracy, and stand backup as non-negotiable every time.
What Experienced DIYers Check That Beginners Miss
Jack Stand Rating
Experienced DIYers match stand capacity to the vehicle’s actual weight, not just a rough guess, and check the rating stamped on the stand itself.
Wiggle Test
Before crawling underneath, they gently push and rock the vehicle to confirm it feels solid on the stands.
Jack Maintenance
They periodically check hydraulic fluid levels and store the jack fully lowered to avoid seal wear.
Second Point of Contact
Many keep a second jack or block nearby as a backup in case the primary jack shifts during a longer job.

Hydraulic Floor Jack
A wide-base hydraulic floor jack may help with more stable lifts on flat garage floors and can make routine tire and brake work more manageable for home DIYers.
Jack Stands (Pair)
A rated pair of jack stands can support the vehicle after lifting, which may make it safer to work underneath than relying on the jack alone.
When to DIY vs When to Call a Professional
When to Contact a Professional: If the vehicle sits unevenly, if you notice fluid leaks near the suspension, or if you are unsure where the correct jack point is, it is safer to contact a mechanic or roadside assistance service than to guess. This also applies if lifting the vehicle might affect a warranty or insurance claim, in which case check your terms first.
Frequently Asked Questions
How do I know where the jack point is on my car?
Check your owner’s manual, which usually includes a diagram. Many vehicles also have a small notch or arrow marking near the rocker panel, just behind the front wheel or ahead of the rear wheel.
Is it safe to use a car jack on grass or gravel?
Soft or uneven ground makes a jack more likely to sink or tip. If possible, move the vehicle to a flat, hard surface, or place a wide, solid board under the jack base first.
Do I really need jack stands, or is the jack enough?
A jack alone is not designed to hold a vehicle’s weight for extended periods. Jack stands are made specifically for that purpose and should always be used before working underneath the car.
Can I use the factory scissor jack for regular maintenance?
A factory scissor jack is generally meant for occasional emergency use, such as a flat tire. For regular DIY maintenance, a hydraulic floor jack paired with jack stands tends to offer more stability.
What size floor jack do I need for an SUV or truck?
Match the jack’s rated lift capacity to your vehicle’s curb weight with a safety margin, and check that the lift height reaches your vehicle’s clearance. A 3-ton or higher rated jack is often used for SUVs and trucks, but always confirm against your vehicle’s actual weight.
What should I do if the jack won’t lift the car?
Check that the release valve is fully closed and that the jack has enough hydraulic fluid. If the problem continues, avoid forcing it and have the jack inspected or replaced.
When should I stop and call a professional instead of jacking up my car myself?
If the vehicle is already leaning, if you cannot confirm the correct jack point, or if you suspect frame or suspension damage, it is safer to contact a mechanic or roadside assistance service instead of jacking the vehicle yourself.
Final Thoughts: Learning how to properly use a car jack is a small time investment that pays off the moment you actually need it, whether that’s a flat tire on the highway shoulder or a routine brake job at home. Stick to flat ground, the correct jack point, and always back the jack up with rated jack stands before working underneath. When something feels uncertain, such as a leaning vehicle or an unclear jack point, check your owner’s manual or contact a qualified professional rather than guessing.
