What does a yellow exclamation mark in the car mean?

A yellow exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many warning lights on the dashboard with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, and transmission fault indicator. Below is a detailed explanation of the yellow exclamation mark warning light: General Fault: A triangle with an exclamation mark inside indicates a general performance or component malfunction in the car. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: A horizontal line with parentheses and an exclamation mark below represents the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, indicating a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or check commonly used bulbs such as turn signals, fog lights, or interior lights to identify the issue. Additionally, during daily vehicle use, the warning lights on the dashboard are divided into yellow and red to indicate different levels of severity: Yellow indicates a fault in the corresponding system that is not very serious. Reduce speed and proceed to a repair shop to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable risks to the vehicle and personal safety. Note: When starting the car, all warning lights will illuminate for a system self-check and will turn off after the check is completed. If a light does not turn on when the ignition is switched on, remains lit, or turns on while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of safety hazards.

What are the causes of false alarms in Mercedes-Benz front radar?

Mercedes-Benz front radar false alarms are caused by dirty radar probes or obstructions. Below is an introduction to related Mercedes-Benz content: 1. Mercedes-Benz SAM: The control unit, also known as the Signal Acquisition and Actuation Module. If the SAM malfunctions, components such as headlights, turn signals, and wipers cannot be controlled while driving, posing safety risks. 2. Mercedes-Benz: A German automotive brand, considered one of the most successful premium car brands in the world. It is renowned for its perfect technical level, stringent quality standards, innovative capabilities, and a series of classic coupe models. The Mercedes three-pointed star has become one of the most famous automotive and brand logos globally. Mercedes-Benz cars not only boast unparalleled quality but also offer a comprehensive range of models, currently producing mainly A-Class (compact cars), C-Class (mid-range sedans and coupes), E-Class (high-end sedans and coupes), S-Class (luxury sedans and coupes), and G-Class (SUV off-road vehicles).

Should the engine oil be changed when the car is hot or cold?

You can change the engine oil whether the car is hot or cold, but relatively speaking, it is better to change the oil when the car is hot. After the car is hot, the viscosity of the oil becomes thinner, and the fluidity improves. Impurities and sludge will be discharged well with the waste oil and will not adhere to the inner surface and bottom of the engine casing. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of about 0.91×10³ (kg/m³). It can lubricate and reduce wear, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is known as the 'blood' of the car. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil, giving it certain new properties, and are an important part of the lubricant.

What should be noted after changing the engine oil?

When changing the engine oil, there are mainly the following points to note: 1. Add oil in moderation: The oil should not be insufficient, but neither should it be excessive; adding too much oil will increase engine resistance and reduce the vehicle's service life; adding too little oil will cause lubrication pressure, leading to low-load operation of the engine, which can also cause significant wear. 2. Choose oil according to the vehicle manual: When purchasing oil, it is essential to buy the oil grade and viscosity as specified in the vehicle manual. Special attention should be paid to the fact that engine oil and diesel oil are not interchangeable. Unless specifically stated, mixing the two can cause significant wear to the vehicle.

What does fault code P0420 mean?

Fault code P0420 indicates that the catalytic converter system efficiency is below the threshold. Possible causes include the use of leaded gasoline damaging the converter, issues with the oxygen sensor, exhaust pipe damage, or catalytic converter leaks. Related information is as follows: 1. Meaning of P0420: To resolve this fault, it's essential to understand that P0420 (Catalyst System Efficiency Below Threshold Bank 1) means the ECU monitors the efficiency using sensors installed before and after the three-way catalytic converter (TWC). 2. Introduction to Catalysts: The effect caused by catalysts in chemical reactions is called catalytic action, and catalysts are also known as promoters in industry. The composition, chemical properties, and mass of the catalyst remain unchanged before and after the reaction; its relationship with the reaction system is like that between a lock and a key, exhibiting high selectivity (or specificity).
