The jack is generally placed 10 to 20 centimeters away from the tire. The car jack is stored in the car's toolbox and is used to lift the vehicle body when replacing a spare tire. Car jacks include pneumatic jacks, electric jacks, hydraulic jacks, and mechanical jacks, with hydraulic and mechanical jacks being the most commonly used. The car jack is used for changing spare tires, making it convenient to replace a flat tire when driving outdoors. When the vehicle is lifted by the jack, never start the engine, as the vibration of the engine or the rotation of the wheels can cause the vehicle to slip off the jack, leading to danger. For various car models, to ensure safety, there are usually fixed positions for using the jack, and it should not be placed on parts like the bumper or crossbeam. Chassis guard plate: Never place the jack directly under the chassis guard plate or the lower control arm of the suspension. Incorrect usage of the jack or supporting it in the wrong place can easily cause damage to the car. Hard ground: The correct method is to park the vehicle securely, preferably on a flat surface, engage the handbrake, shift automatic transmission cars into P gear, and ensure the ground supporting the jack is also hard. Slipping: If the ground is soft, such as sand, grass, or mud, it is recommended to place a hard wooden board or stone slab under the jack to prevent the jack from sinking or slipping.

I drive a regular sedan, and the jack is located at the bottom of the trunk. After opening the trunk, you can directly see it by lifting the floor mat or the spare tire cover. The position may vary slightly depending on the vehicle model; for example, in SUVs, it might be in a sidewall compartment or an inner groove of the rear door. The main purpose of locating it here is to ensure quick access during emergency tire changes. I recommend confirming that the car is parked on level ground and the handbrake is fully engaged before use, then aligning the jack with the marked points on the vehicle's undercarriage—avoid placing it incorrectly to prevent damage to the body or instability. During routine car washes or maintenance, remember to check if the jack is in its proper position, not obstructed by debris or rusted, which could affect functionality. This placement is well-designed to minimize trunk space usage while ensuring safety and easy access. Developing good habits can save a lot of hassle.

Many beginners may not know that the jack is usually hidden in the trunk, and you can find it by lifting the trunk floor. My advice is not to overload the trunk with heavy items that might press on it and cause deformation. The location varies by vehicle; common spots include under the trunk floor for sedans or on the side for SUVs. When using it, choose a flat surface, turn off the engine, engage the parking brake or put the car in P mode, then place the jack on the designated chassis indentation—avoid placing it near the tire edge to prevent tipping risks. I’ve also encountered cases where the location wasn’t obvious, so checking the manual or searching online for your car model’s diagram can help. Regularly inspect the tools for completeness and smooth operation to ensure smooth tire changes and avoid panic-induced accidents. Remembering these details can enhance safe driving awareness.

Location is crucial, typically beside the spare tire in the trunk. Placement is designed for quick access in emergencies. Don't overlook the marked area under the car—the jack must align there for stable lifting. While locations vary across vehicles, the principle remains the same; core positions are similar for SUVs and sedans. Always operate on level ground to avoid dangerous wobbling on slopes. Additional tip: Regularly check the location to prevent tool loss or rust, which can slow down tire changes. Safety first is the fundamental rule.
