What a Car Jack Does and Why the Basics Matter
A car jack is a mechanical or hydraulic lifting tool designed to raise one corner or side of a vehicle off the ground. Most vehicles come with a small scissor jack in the trunk for emergencies, while home garages often use a hydraulic floor jack for easier, smoother lifting. Learning how to use a car jack properly means understanding not just how to raise the vehicle, but how to do it in a way that keeps you and the car stable throughout the process.
For a beginner, the biggest thing to grasp is that a jack is a lifting device, not a holding device. It raises the vehicle, but it should never be the only thing supporting the car while you work underneath it. Experienced DIYers know this distinction well and always pair a jack with a jack stand for any task that takes more than a minute or two.
Why Knowing How to Use a Car Jack Safely Matters
Every driver eventually faces a flat tire, a suspension check, or a routine oil change that requires lifting the car. Doing this safely matters because a vehicle that shifts or falls while raised can cause serious injury or expensive damage. In my testing experience, most jack-related close calls happen not because the tool failed, but because it was placed on the wrong spot or on unstable ground. Learning how to use a car jack the right way removes that risk almost entirely.
This matters differently depending on your vehicle and situation. A roadside tire change on a highway shoulder carries different risks than a weekend brake job in a level driveway. Newer vehicles often have clearly marked lift points in the owner’s manual, while older vehicles may require more care to identify a solid, flat section of the frame or pinch weld.
Scissor Jack vs Hydraulic Floor Jack
Most drivers will choose between the compact scissor jack that ships with their car and a hydraulic floor jack kept at home. Here is how the two compare for everyday use.
Before You Start: Preparation and Safety Checks
Before you even touch the jack handle, a few preparation steps make the entire process safer. Park on level, firm ground whenever possible, since a slope or soft surface like gravel or grass increases the chance the jack could tip or sink under load.
Level Ground
Choose a flat, hard surface such as pavement or a driveway. Soft or sloped ground can cause the jack to shift once weight is applied.
Parking Brake
Engage the parking brake and, if available, put an automatic transmission in Park or a manual in gear before lifting.
Wheel Chocks
Place chocks or heavy blocks against the wheels diagonally opposite the one being lifted to stop unwanted rolling.
Locate Lift Points
Check your owner’s manual for the manufacturer’s recommended jack points, usually reinforced sections along the frame rail.
Note: Every vehicle has designated jack points marked in the owner’s manual. Using an incorrect spot, such as the floor pan or exhaust, can dent the body or cause the jack to slip.
Here is the typical setup sequence before lifting begins, shown as a quick visual guide.

Practical guide: this order applies whether you’re changing a tire roadside or doing home maintenance in a garage.
Step-by-Step: How to Use a Car Jack
Once your preparation checks are done, follow this sequence to use a car jack correctly and safely.
Confirm the vehicle is secure. Parking brake on, wheels chocked, and the vehicle in Park or gear before you touch the jack.
Position the jack under the correct lift point. Line the jack’s saddle or lift pad up squarely with the reinforced spot on the frame or pinch weld.
Raise the jack until it just touches. Turn the handle or pump slowly until light contact is made, then double-check alignment before lifting further.
Lift the vehicle slowly and steadily. Watch the contact point as you go; stop immediately if the jack leans or the car shifts sideways.
Add a jack stand before working underneath. Once the wheel clears the ground, slide a rated jack stand under a nearby support point and lower the car slightly onto it.
Complete the task. Change the tire, inspect the underside, or carry out the repair while the vehicle rests on the stand, not the jack alone.
Lower the vehicle carefully. Raise the jack slightly to remove the stand, then lower the jack slowly and evenly until all wheels are back on the ground.
Safety Note: Never place any part of your body under a vehicle that is supported only by a jack. Jacks can slip, especially on uneven ground or if overloaded, so a jack stand is essential for any task longer than a quick wheel swap.
The decision path below can help you judge whether it is safe to continue at each stage of the lift.
Safe-Use Decision Path
Is the ground flat and firm? If no → move to a better spot before jacking.
Is the jack under the correct lift point? If no → reposition before raising further.
Does the vehicle feel stable as it rises? If no → lower slowly and start over.
Will you work underneath the car? If yes → add a jack stand before proceeding.
Practical guide: treat any “no” answer as a stop sign until it’s corrected.
Common Problems When Using a Car Jack
Even with careful technique, issues can come up. Knowing the likely cause helps you fix the problem instead of forcing the jack further.
Best-Practice Technique vs Less-Effective Technique
The checklist dashboard below highlights the checks most beginners skip.
Pre-Lift Checklist Dashboard
☑ Ground is flat and firm
☑ Parking brake engaged
☑ Wheels chocked
☑ Correct lift point identified
☑ Jack stand ready nearby
Practical guide: if any box is unchecked, pause before lifting further.
Choosing the Right Jack for Your Vehicle
Not every jack suits every situation. Matching the tool to the job and vehicle type keeps things safer and easier.
Heads-Up: Double-check your jack’s weight rating against your vehicle’s curb weight before you buy or use one. A jack rated too close to the vehicle’s weight offers little safety margin.
Common Mistakes to Avoid When Using a Car Jack
The fit dashboard below compares how well each jack type suits common ownership situations.
Jack Fit by Ownership Style
Occasional driver, emergencies only: Scissor jack is a practical guide fit.
Weekend DIYer: Hydraulic floor jack plus jack stands.
Frequent maintenance / multiple vehicles: Higher-capacity floor jack with a wide base.
Practical guide: match the jack to how often, not just how heavy, you lift.
Pro Tips From Experienced DIYers
Experienced car owners tend to notice small details beginners often miss. They check the jack’s release valve before starting, keep a piece of plywood on hand for soft ground, and always test the vehicle’s stability with a gentle push before crawling underneath.
Tip: Keep a flat piece of wood or a rated base plate in your trunk. It can support the jack’s foot on gravel or a soft shoulder, which may help prevent sinking during a roadside change.

When to Contact a Professional
Knowing how to use a car jack covers routine tire changes and light maintenance, but some jobs call for a qualified mechanic instead. If a jack repeatedly fails to hold pressure, if you notice frame damage or rust at the lift points, or if the task involves brakes, steering, or suspension components beyond simple wheel removal, it’s worth having a licensed technician handle it.
When to Contact a Professional: If you’re unsure where your vehicle’s lift points are, if the jack feels unstable even on flat ground, or if the repair involves brake, steering, or structural work, check with a qualified mechanic rather than continuing on your own.

Frequently Asked Questions
Where should I place a car jack under my vehicle?
Place it under the manufacturer’s marked lift point, usually along the frame rail or pinch weld, as shown in your owner’s manual. Avoid the floor pan, exhaust, or plastic trim.
Is it safe to use a car jack on a slope?
It’s best avoided. A slope increases the risk of the jack or vehicle shifting. Move to flat, firm ground before lifting whenever possible.
Do I always need a jack stand, or is the jack enough?
A jack stand is strongly recommended for any task where you’ll be underneath or near the vehicle for more than a moment. Jacks can slip or lose pressure, so a stand adds essential backup support.
How do I know if a jack is rated for my car’s weight?
Check the jack’s weight capacity label and compare it to your vehicle’s curb weight, found in the owner’s manual or on the manufacturer’s website. Choose a jack rated comfortably above that weight.
Can I use a car jack on gravel or grass?
It’s not ideal, since soft ground can let the jack sink unevenly. If you have no other option, place a flat, sturdy board under the jack’s base first.
What should I do if the jack starts to lean while lifting?
Stop lifting immediately, lower the vehicle slowly and carefully, then reposition the jack on firmer ground or a more accurate lift point before trying again.
When should I let a mechanic handle the job instead?
If the task involves brakes, steering, suspension, or you notice frame damage or rust near the lift points, it’s safer to have a qualified mechanic take over.
Final Thoughts
Learning how to use a car jack safely comes down to a few consistent habits: flat ground, the correct lift point, a slow and steady lift, and a jack stand for any extended work. Once these steps become routine, changing a tire or handling light maintenance feels far less stressful. For anything beyond basic tire changes, especially work touching brakes, steering, or the vehicle’s structure, check your owner’s manual and consult a qualified professional before proceeding.
