The jack position on a Mercedes-Benz is generally located about 10-20 centimeters away from the tire. Here are relevant details: 1. Chassis Cover Plate: Never place the jack directly under the chassis cover plate or the lower control arm of the suspension. Incorrect jack usage or improper support points can easily cause damage to the vehicle. 2. Hard Surface: The correct method is to park the vehicle securely, preferably on a level road surface, engage the parking brake, shift automatic transmission vehicles into P gear, and ensure the ground supporting the jack is also a hard surface. 3. Slippage: If the ground is soft, such as sand, grass, or mud, it is advisable to place a hard wooden board or stone slab under the jack to prevent sinking and slipping.

Last time I changed tires, I specifically checked the manual. For Mercedes-Benz, the jack must be placed on the support points of the side sill under the door. The exact locations are about 20 cm behind the front wheel and about 20 cm in front of the rear wheel. If you squat down and look under the car, you'll find small triangular or U-shaped marked metal blocks—those are the manufacturer-designed load-bearing points. Never jack up on weak areas like the fuel tank or exhaust pipe. I've seen someone damage the chassis by jacking in the wrong spot, resulting in repair costs over ten thousand. When using the car's jack, make sure to align it with the groove, engage the parking brake and shift into P before lifting, and it's best to place bricks in front of and behind the tire to prevent rolling. If you're really unsure, calling Mercedes-Benz roadside assistance is safer.

Our auto repair instructor repeatedly emphasized that Mercedes-Benz chassis have four dedicated support points, located right beneath the sill beams. The front points are positioned about a palm's width inward from the wheel arches near the front wheels, while the corresponding rear points sit ahead of the suspension brackets. These marked locations feature either raised metal indicators or grooves where the U-head of a jack fits perfectly. Always park on firm, level ground and use wheel chocks before lifting. During a practical lesson, a senior student once accidentally jacked up the fuel tank guard plate and punctured it. For unfamiliar owners, we recommend checking the diagram on the door frame sticker or using a phone to photograph the underbody markings before proceeding.

As a female car owner, I am particularly cautious. The support points for Mercedes-Benz are located directly below the rocker panel beams, with two on each side—one behind the front wheel and one in front of the rear wheel. If you look down at the underside of the car, you'll notice small notched squares, which are firm metal protrusions when touched. Before changing a spare tire, I always use the jack to simulate the position to ensure it's properly aligned before proceeding. Be careful to avoid the thin sheet metal and fuel lines—I once scraped off some paint and worried about rust. If the ground is uneven, use a wooden board under the jack to increase stability. If you're really unsure, call Mercedes-Benz's 24-hour roadside assistance.

From a structural design perspective, Mercedes-Benz has installed multiple reinforcing ribs on the lower longitudinal beams of the door panels as jacking points. These are specifically positioned in the beam area offset 15-30cm from the center points of the front and rear wheels, where the steel plate thickness is three times that of a regular vehicle underbody. The front point is located near the firewall, while the rear point is adjacent to the suspension bushing mount. The Mercedes-Benz E-Class also features wave-shaped anti-slip patterns at these points, providing greater stability compared to Japanese vehicles. Incorrect jacking can lead to deformation of the rocker panel beams, potentially requiring cutting and repair if doors fail to close. Modified vehicles should take special care to avoid interfering with aftermarket wiring and piping installations.
