Place the jack on the raised ridge beneath the car's sill, which runs from front to back and can serve as a support point. A jack is a lightweight lifting device that uses a lifting component as its working mechanism to raise heavy objects within a small range of motion via a top saddle or bottom claw. Precautions for using a jack: 1. Secure the vehicle to prevent tipping; 2. Implement safety warning measures; 3. Ensure the jack's base is firmly fixed; 4. Know the jack's maximum load capacity; 5. Align with the vehicle chassis's support points; 6. Perform lifting operations steadily and slowly; 7. Placing a spare tire under the car adds extra safety.

Once when changing a tire, I couldn't find the correct jacking point and nearly tipped my car over – it was terrifying. Since then, I always refer to the vehicle's user manual to locate the specific jacking points, usually along the metal rails under the car's sides where reinforced areas prevent body deformation. Never place the jack on plastic covers or fragile components, as it may slip or damage the car, posing serious risks. I also carry a portable jack for safer emergency use off-road. Additionally, always ensure the ground is level and stable, and don't forget to engage the parking brake during tire changes. The key is to practice several times to familiarize yourself with your car's specifics, so you won't panic in emergencies.

As a seasoned driver who has changed tires for over a decade, I know exactly where to place the jack. Most vehicles have designated lifting points underneath, such as the side skirts or metal protrusions on the frame, which are designed to be sturdy and reliable. Wrong spots like under the engine or the wheel arch area can cause the jack to slip, or even lead to the car collapsing and causing injury. I remember once helping a neighbor with his car—he placed the jack on the plastic fender, causing the entire car to tilt dangerously. Luckily, we noticed it in time to avoid an accident. Now, I always double-check the position before operating and recommend that beginners start with simpler car models, avoiding work in the rain or on slopes. Developing good habits can save lives.

During a road trip with friends, his tire blew out, and I reminded him that the jack must be placed at the designated position on the chassis, where the steel structure is sturdier. Usually, there are markings near each wheel on the side of the chassis, and a few light taps can help locate the solid point. I emphasized not to place it near the suspension or fuel tank to avoid causing bigger issues. Similar experiences include paying attention to tire pressure, which can help prevent accidents. Overall, it's quite simple—just check the manual.

I enjoy tinkering with car repairs myself, and the positioning of the jack is quite particular. Different car models have different locations: for small cars, it's usually on the metal beam inside the wheel, while SUVs might have it in front of the rear axle. The key is to find structurally strong points and avoid soft areas. In practice, when using a jack, I first clear any debris from the ground, then align it properly and slowly raise it, ensuring the jack head is firmly in place. Incorrect practices, such as jacking under the door beam, can damage the paint and potentially cause deformation over time. I've also seen modified cars with additional reinforcement points, so understanding your own vehicle is crucial. After changing a tire, don't forget to tighten the nuts and check them several times. Doing it right can save a lot of trouble.
