When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, or lighting system fault. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission issue or that the transmission fluid level is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line with an exclamation mark below a parenthesis represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. Additionally, a red exclamation mark inside a circle with parentheses indicates a braking system warning, typically due to braking system failure or low brake fluid level. Immediate inspection of the braking system is necessary to avoid accidents.

What are the plastic posts in parking spaces called?

The two rubber posts in parking spaces are called rubber wheel stops, also known as wheel chocks, reversing pads, parking stoppers, or car stoppers. The main functions of rubber wheel stops are as follows: Function 1: They are made of high-strength natural rubber through vulcanization and high-pressure synthesis, offering excellent compressive performance and a certain degree of softness in the slope. Function 2: The black and yellow alternating design with reflective materials complies with international standards, making them highly visible and featuring properties such as deceleration, anti-slip, wear resistance, and reduced wear on vehicle tires. Function 3: They prevent vehicles from overrunning when reversing into garages, avoiding collisions, and are the best facilities for ensuring vehicles are parked in the correct position.

At what speed can Audi's active braking system brake

Audi's active braking system activates at speeds above 30km/h. It uses radar waves to monitor blind spots that are difficult for drivers to observe, providing voice alerts to prompt drivers to pay attention to driving safety, or the vehicle can actively brake. This system is highly practical for urban congested roads and traffic light intersections. Vehicle safety systems are mainly divided into two types: active safety systems and passive safety systems. Here are the relevant introductions: 1. Active safety systems: These include electronic devices such as ABS and ESP. 2. Passive safety systems: These involve the vehicle's energy-absorbing structure, seat belts, airbags, etc.

How to Quickly Remove Snow from a Car

Methods for quickly removing snow from a car: 1. If you have a plastic shovel at home, you can use it to sweep away the snow on the car; 2. Pour warm water on the harder ice patches, and once the snow shows signs of melting, put on thick gloves to brush off the snow; 3. If there is a large accumulation of snow on the car, you can start the car first to allow the engine's temperature to rise, which will help melt the snow. If the car is covered with snow, it is necessary to clean it promptly because uncleared snow can obstruct the driver's view. If the windshield is covered with snow, it becomes impossible to see the road ahead. Additionally, heavy snow accumulation on the car can cause the windows and spray nozzles to freeze, affecting their functionality.
