What are the essential tools to have in a car for annual inspection?

The essential tools to have in a car for annual inspection are a warning triangle, fire extinguisher, and jack. Warning triangle: If the car is not equipped with a warning triangle, failing to set up the warning sign behind the vehicle after a breakdown or accident will result in penalty points, and it is extremely dangerous as it can easily lead to secondary accidents. Fire extinguisher: If medium-sized and above passenger vehicles or hazardous goods transport vehicles are not equipped with fire extinguishers, the traffic authorities will penalize the driver according to regulations. Cars without fire extinguishers will not pass the annual inspection. For safety reasons, family cars should also be equipped with fire extinguishers. Jack: When driving, it's inevitable to encounter a flat tire. A jack is needed when changing a tire. The jack should be placed on the inner side of the car's side skirt, approximately 20 cm behind the front wheel and 20 cm in front of the rear wheel. Without a jack, it will be very difficult to change a spare tire.

Why is the car shaking severely?

The severe shaking of the car may be caused by the following three reasons: Wheel imbalance: Wheel imbalance is a common issue in many vehicles. During manufacturing, it is impossible to ensure uniform quality of tires and steel rims, so wheels must undergo dynamic balancing after assembly. Moreover, as tires wear over time, periodic dynamic balancing is necessary after certain mileage. Loose suspension structure: The chassis suspension consists of various links and support arms, which are connected through ball joints and rubber bushings. Normally, these components are tightly connected, but as the ball joints and bushings wear out, the connections loosen, causing the suspension to become loose and resulting in body shaking while driving. Excessive steering gear backlash: The steering system of a car uses a rack-and-pinion mechanism to convert the rotational motion of the steering wheel into the swinging motion of the wheels. Over time, wear between the rack and pinion creates backlash, causing slight left and right movements of the wheels even without steering input, leading to a sensation of body shaking.

What car is known as the 'mobile sofa'?

The 'mobile sofa' refers to the seventh-generation Teana. Features: The seventh-generation Teana's ergonomic seats feature three-layer cushioning technology, providing comfortable seating positions for all body types. The newly upgraded 3D side wing support effectively minimizes body sway, while the generously padded seats truly live up to its 'mobile sofa' reputation. The steering wheel adopts a sporty flat-bottom design with optimal size and excellent grip. Exterior: The seventh-generation Teana showcases a completely new design language with more youthful and sporty elements. It has abandoned the traditional 'TEANA' naming and adopted the 'ALTIMA' designation consistent with overseas models. The front fascia features a more exaggerated V-shaped chrome grille, complemented by expected full LED headlights. The panoramic sunroof is specifically designed for Chinese consumers. The angular rear design harmonizes with the bold front, featuring three-dimensional taillights with smoked edges - though unfortunately not LED-lit.

What does the red triangle with a car inside mean on a Mercedes dashboard?

Mercedes dashboard red triangle with a car inside represents the Distance Warning Light, which reminds the driver to maintain a safe distance from the vehicle ahead to prevent rear-end collisions and avoid traffic accidents. When this light is on, simply maintaining a proper distance allows normal driving. Additional information: 1. Front and rear fog light indicators: These show the working status of the front and rear fog lights. When the fog lights are turned on, both indicators light up. 2. Turn signal indicators: When the turn signal is activated, the corresponding indicator flashes at a certain frequency. When the hazard warning lights are pressed, both indicators light up simultaneously. The indicators automatically turn off once the turn signals are deactivated. 3. High beam indicator: This shows whether the headlights are in high beam mode. Normally, this indicator is off but lights up when the high beams are activated or during the momentary high beam function. 4. Seatbelt indicator: This displays the seatbelt status. Depending on the vehicle model, the light may stay on for a few seconds as a reminder or until the seatbelt is fastened. Some vehicles may also include an audible alert.

How to Determine a Car's Manufacturing Date from the Glass?

There is a code located at the bottom left or right corner of the car window glass. In the last or second last row, you will find a number and several small black dots, which indicate the production date of the glass, and consequently, the car's manufacturing date. The number represents the production year of the glass, while the small black dots are used to determine the production month. Below is an introduction about car glass: 1. The markings on the front and rear windshields are different because they belong to different types of glass, and the manufacturer's part numbers also vary. 2. Generally, the glass marking consists of a combination of symbols, numbers, and English letters printed in the lower left corner of the glass. It includes information such as the car brand, glass brand, certification mark, glass type, and production date. 3. The safety performance of car windshields is extremely important. Typically, car glass is made of silica glass, with silicon dioxide content exceeding 70%, and the rest composed of sodium oxide, calcium oxide, magnesium, etc., manufactured through the float glass process.
