How to Use Car Jack That Comes with Car: Complete Guide and Facts

A flat tire becomes much more stressful when the jack is hidden under the cargo floor and its handle looks unlike anything in a toolbox. The factory jack is usually small, awkward, and designed for one specific lifting point, so guessing can bend a rocker panel or leave a vehicle unstable.

I wrote this guide to explain how to use car jack that comes with car safely, from finding the correct lift point to tightening the replacement wheel. I will also cover what the factory jack can and cannot do, when jack stands are necessary, and which common shortcuts create real danger.

The instructions below apply mainly to the compact scissor jack or small emergency jack supplied with many passenger cars. Your owner’s manual remains the final authority because lift points, wheel-storage locations, and jack designs differ by vehicle.

What the Factory Car Jack Is Designed

A factory car jack is an emergency lifting device. Its job is to raise one corner of a vehicle high enough to remove a damaged wheel and install a spare tire. It is not normally intended for routine maintenance, long-term support, lifting the entire vehicle, or holding a car while somebody works underneath it.

Many cars include a scissor jack This jack has two hinged arms that extend as a threaded screw turns Other vehicles use a compact bottle-style or screw-type jack.

The factory jack usually has three important limitations:

• It may have a relatively narrow base that can sink into soft pavement or dirt.
• It is often rated only for the vehicle and lifting position specified by the manufacturer.
• It provides little stability compared with a professional floor jack and jack stands.

A compact emergency jack is acceptable for a roadside tire change when used correctly. I would not choose it for brake work, suspension repairs, oil changes, or any task requiring a person to place a body part beneath a raised vehicle.

Before Raising the Vehicle

Preparation matters as much as turning the jack handle. A vehicle can move unexpectedly if the parking brake, transmission, wheel chocks, and ground conditions are ignored.

Find a safe location

Move as far away from traffic as possible A level hard surface such as clean asphalt or concrete is best Avoid a hill soft shoulder grass loose gravel.

Turn on the hazard flashers. At night or in poor visibility, use warning triangles or other roadside warning equipment if available and appropriate. Keep passengers away from the traffic side of the car, and never position yourself between the vehicle and moving traffic.

Secure the car

1. Put the transmission in Park if the vehicle has an automatic transmission. Select first gear or reverse if it has a manual transmission, following the owner’s manual if it specifies another setting.
2. Apply the parking brake firmly.
3. Turn off the engine and remove the key or keep the vehicle powered down as directed by the manufacturer.
4. Place a wheel chock in front of and behind a tire that will remain on the ground. A commercial chock is best; a solid block can be a backup if the manual permits and no proper chock is available.

Chock the wheel diagonally opposite the corner being lifted. For example, if the right-front tire is being changed, secure the left-rear wheel. If the failed tire is on a driven axle, securing the opposite wheel is especially important, but chocking an additional wheel can provide more control when conditions allow.

Collect the equipment

Locate the jack, jack handle, lug-wrench adapter, spare tire, and any locking-wheel-nut key. Some cars store the handle in several pieces, while others require the wrench to connect to a socket on the jack. Check that the spare tire is inflated and that the tools are not damaged.

Read the tire-changing section of the owner’s manual before lifting. Look for the approved lifting point, the direction for inserting the handle, and any instructions for a temporary spare. A “donut” spare may have a lower speed limit and a limited driving range printed on its sidewall or in the manual.

How to Use the Car Jack That Comes With the Car

The basic process is straightforward loosen the wheel fasteners place the jack at the correct point lift until the tire clears the ground replace the wheel and lower.

1. Remove the hubcap if necessary

If a plastic wheel cover hides the lug nuts, remove it with the tool supplied by the manufacturer or with a suitable flat tool protected by a cloth. Pry gently at the location shown in the manual. Do not force a cover that is retained by a specific clip or center cap.

2. Loosen the lug nuts before lifting

Fit the lug wrench fully onto the first lug nut and turn it counterclockwise. If the nut is tight, press the wrench down steadily rather than jumping on it or using an improvised extension. Loosen each nut about one turn, but leave every nut threaded on the wheel.

Do not remove the lug nuts while the tire is still supporting the car. The weight of the vehicle keeps the wheel from turning and helps prevent sudden movement.

3. Identify the correct lifting point

Look beneath the side sill, near the wheel being changed, for a reinforced pinch-weld area, notch, arrow, slot, or molded marking. Many unibody cars have a specific section of the lower body designed to receive the factory jack. Some trucks and SUVs use a frame point instead.

The correct point is structural and specifically identified by the manufacturer. Do not place the jack under a random section of the floor pan, plastic trim, exhaust component, suspension arm, fuel tank, differential, or thin body panel. A wrong location can deform the vehicle or allow the jack to slip.

4. Position the jack

Set the jack upright on firm level ground Center its lifting saddle under the approved point On a scissor jack the saddle may have a groove that must align with the vehicle s pinch weld Make sure the jack s base sits flat and.

Before lifting, confirm that the jack is vertical rather than leaning toward or away from the vehicle. A slight misalignment can become a serious tilt as the jack extends.

5. Raise the vehicle slowly

Turn the handle in the direction shown in the manual. Pause after several turns to check that the saddle remains centered and the base has not shifted. Lift only until the damaged tire is barely clear of the ground, generally leaving enough room to remove the wheel and install the inflated spare.

Do not raise the car higher than necessary. Extra height increases the amount of instability and makes a factory jack work harder. Keep hands, feet, and loose clothing away from the moving jack and the underside of the vehicle.

6. Remove the wheel

Finish removing the loosened lug nuts by hand and put them somewhere clean Pull the wheel straight toward yourself If it is stuck to the hub because of.

If the wheel will not come off without force, roadside assistance is safer than escalating the problem beside traffic. A stuck wheel may require tools and support that the factory kit does not provide.

7. Install the spare tire

Align the spare with the wheel studs or hub and slide it into place. Thread every lug nut by hand for several turns. Hand-starting prevents cross-threading, which can damage the stud or nut.

Tighten the nuts lightly with the wrench while the tire is still raised. Use a crisscross or star sequence rather than tightening adjacent nuts in a circle. The wheel needs to sit evenly against the hub before the vehicle’s weight returns to it.

8. Lower the car and tighten the nuts

Turn the jack handle slowly in the lowering direction. Lower the vehicle until the tire touches the ground and cannot rotate, but do not remove the jack yet. Tighten the lug nuts firmly in a star pattern.

Lower the vehicle completely remove the jack and perform a final star-pattern tightening The correct torque is the vehicle manufacturer s specification usually found in the owner s.

9. Finish the roadside check

Reinstall the hubcap only if it fits the spare wheel. Return the damaged tire, jack, handle, chocks, and wrench to their storage locations so they do not move around the cabin or cargo area. If the spare is a temporary tire, follow its speed and distance restrictions.

After driving a short distance, stop in a safe place and confirm that the spare still appears secure. Have the lug-nut torque checked with a torque wrench as soon as possible, especially if the wheel was installed without one. Repair or replace the damaged tire before relying on the spare for normal driving.

Where to Place the Jack on Common Vehicles

The exact location is vehicle-specific, but common patterns can help explain what to look for.

Vehicle area	Typical factory lift location	Important caution
Passenger car front	Marked reinforced pinch weld near the front wheel	Do not lift on the plastic rocker-panel cover or thin floor metal.
Passenger car rear	Marked reinforced pinch weld near the rear wheel	Confirm that the jack saddle fits the seam or notch.
Body-on-frame truck	Specified frame section or axle-related point	Use only the location listed for that truck and axle configuration.
SUV or crossover	Reinforced body lift point or designated frame point	Different trims and four-wheel-drive systems may use different points.

Never assume that a strong-looking component is a lifting point. The owner’s manual may show a diagram because a few inches can separate a safe structural point from a fragile panel.

Factory Jack Versus a Floor Jack

The supplied jack is compact and usually fits the vehicle’s storage compartment. That makes it useful for an emergency, but its small footprint and slow operation make it less stable and convenient than a quality floor jack.

A floor jack is generally better for maintenance when it has enough lifting capacity reach and a saddle suitable for the vehicle It should be used on level.

A jack stand supports the vehicle after it has been raised It is not a replacement for the jack during the lifting process and a jack should not.

What Not to Do With a Car Jack

• Do not work under a car supported only by the factory jack. The jack can tip, slip, collapse, or lose contact with the vehicle.
• Do not lift on a sloped surface unless an emergency leaves no safer option; in that situation, roadside assistance is usually the better choice.
• Do not place wood, bricks, rocks, or unstable objects under the jack to create extra height.
• Do not use the jack to lift more than the vehicle or location it is rated for.
• Do not start the engine, shift the transmission, or allow passengers to enter while the vehicle is raised.
• Do not remove all lug nuts before the tire is off the ground.
• Do not crawl beneath the vehicle to retrieve a dropped tool.
• Do not continue lifting if the jack leans, the base sinks, the saddle slips, or the body begins moving unexpectedly.
• Do not use a spare tire with a damaged sidewall, missing air, or an incompatible size.

If anything looks unstable, lower the vehicle if it can be done safely, move away from the car, and call roadside assistance. A damaged tire is inconvenient; a falling vehicle can be fatal.

Common Mistakes and Better Choices

Trying to lift on a soft shoulder

A shoulder may look flat while its surface is loose underneath. As the car’s weight transfers to the jack, the base can sink or tilt. If moving to a hard surface is impossible, place only a manufacturer-approved support board under the jack if the owner’s manual allows it. Never improvise with unstable debris.

Forgetting that the spare may be temporary

A compact spare is not always equivalent to the original tire. It may change handling, braking, traction, and ground clearance. Check the sidewall and manual for the maximum speed and driving limitations. Avoid abrupt turns and hard braking, and drive directly to a tire shop or repair location.

Overtightening the lug nuts

Standing on the lug wrench or using a long pipe can overstress studs and make later removal difficult. Uneven or excessive tightening can also affect how the wheel sits against the hub. Use the specified torque instead of relying on maximum physical force.

Ignoring the tire-pressure warning

After installing the spare, check its pressure as soon as possible. Some temporary spares require substantially more pressure than ordinary passenger tires, so visual inspection is unreliable. Reset or reinitialize the tire-pressure monitoring system only according to the vehicle’s instructions.

Leaving the jack uninspected

A factory jack that has remained in a damp trunk for years may have corrosion, a bent screw, missing hardware, or a cracked plastic handle. Inspect it before a trip. Operate it briefly without a load to confirm that it extends and retracts smoothly, but never use a damaged jack to support a vehicle.

When to Call for Roadside Assistance

Roadside assistance is the right choice when traffic is close, the ground is unsafe, the vehicle is loaded beyond normal conditions, the wheel is seized, the jack or spare is missing, or the damaged tire is on the side exposed to fast-moving traffic.

Call for help if the car has an unusual suspension system, air suspension, a very low ride height, or a lift-point diagram you cannot interpret. Electric vehicles and hybrids may also have special lifting restrictions, high-voltage component concerns, or different procedures. The owner’s manual should be checked before attempting a wheel change.

A professional tire technician can also handle a damaged wheel, a tire that has come off the bead, multiple flat tires, or a vehicle that cannot be safely moved. Saving a few minutes is not worth taking a risk with an unstable jack.

How to Store and Maintain the Emergency Kit

Keep the jack, handle, wrench, wheel-lock key, spare, and towing eye in their designated locations. Secure each item so it cannot become a projectile during sudden braking. Keep the owner’s manual accessible, either in the glove compartment or in the vehicle’s approved digital system.

Inspect the spare tire at least when checking the other tires. Look for low pressure, sidewall cracking, corrosion around the wheel, and expiration or replacement guidance for temporary tires. Check the jack for rust and verify that its handle fits properly.

It is also sensible to carry work gloves, a flashlight, reflective clothing, a small kneeling pad, and an approved warning device. These additions do not replace safe positioning, but they make an emergency stop easier to manage.

FAQ: Using the Car Jack That Comes With the Car

Can I use the factory car jack to change a tire?

Yes. The factory jack is designed to raise the vehicle enough to replace one wheel when it is placed at the manufacturer’s designated lift point on firm, level ground. It should be used as an emergency tire-changing tool, not as permanent support or a general repair stand.

Should I loosen lug nuts before using the car jack?

Yes. Loosen each lug nut about one turn while the damaged tire remains on the ground. This prevents the wheel from spinning and reduces the chance of moving the vehicle while the jack is supporting it. Do not remove the nuts until the tire is slightly off the ground.

Where is the correct jack point?

The correct point is normally marked near the wheel by a notch, arrow, reinforced pinch weld, or diagram in the owner’s manual. It may be on the frame for some trucks and SUVs. Never choose a location based only on appearance, and do not lift on plastic trim, exhaust parts, or thin body panels.

Can I use the factory jack on gravel or dirt?

A factory jack is safest on a hard, level surface. Gravel and dirt can let its narrow base sink or slide. Move to firm pavement if possible. If the vehicle is already in a dangerous location and cannot be moved safely, call roadside assistance rather than improvising a platform.

Can I get under a car supported by its factory jack?

No. A factory jack is not a safe substitute for jack stands. Never place your body beneath a vehicle supported only by that jack, even if the car appears stable. Use properly rated stands on approved support points for repair work, or have the work performed by a qualified technician.

How high should I raise the vehicle?

Raise it only until the damaged tire clears the ground enough to come off and the spare can slide into position. Extra height increases instability and creates no benefit. Stop immediately if the jack leans, shifts, sinks, or loses proper contact with the lifting point.

How tight should the lug nuts be after changing the tire?

Tighten them to the vehicle manufacturer’s specified torque, using a torque wrench when possible. Tighten in a star pattern so the wheel seats evenly. Have the torque checked promptly if a torque wrench was not available during the roadside change.

Can I drive normally on the temporary spare?

Usually not. Follow the speed, distance, pressure, and axle-position restrictions printed on the spare tire and listed in the owner’s manual. A temporary spare can affect handling and braking, so drive cautiously and replace or repair the original tire as soon as possible.

Conclusion

Learning how to use car jack that comes with car is mainly about controlled preparation choose a safe surface secure the vehicle loosen the lug nuts before lifting.
