ABS and ESP lights are on due to two contact points being covered in mud. Anti-lock Braking System: The Anti-lock Braking System (ABS) functions by automatically controlling the braking force during vehicle deceleration, preventing wheel lock-up and maintaining a rolling-sliding state (with a slip ratio around 20%) to ensure maximum wheel-to-road adhesion. Electronic Stability Program: ESP (Electronic Stability Program) is a type of traction control system. Compared to other traction control systems, ESP not only manages the drive wheels but also regulates the non-driven wheels. For instance, in rear-wheel-drive vehicles prone to oversteer where the rear wheels lose traction and cause fishtailing, ESP stabilizes the car by braking the outer front wheel. Conversely, during understeer, ESP corrects the trajectory by braking the inner rear wheel to adjust the driving direction.

Which country produces Bilstein shock absorbers?

Bilstein shock absorbers are produced in Germany. Here is some relevant information about Bilstein shock absorbers: 1. Bilstein shock absorbers utilize a gas-chamber filling system, which enhances the shock absorber's responsiveness and effectively prevents the mixing of damping oil and gas to form bubbles. 2. Performance of Bilstein shock absorbers: 1. The heat generated inside the shock absorber warms the damping oil, causing its viscosity to thin. 2. The thinned damping oil reduces resistance when passing through the oil valve, leading to a decrease in damping force, known as shock fade (Shock-Fade).

When did Beijing start implementing China VI emission standards?

Beijing implemented the China VI emission standards for light-duty gasoline vehicles on January 1, 2020. Here are the relevant details: 1. Light-duty gasoline vehicles refer to M1, M2, and N1 category vehicles with a maximum design total mass not exceeding 3500kg. However, starting from July 1, 2019, heavy-duty gas vehicles and heavy-duty diesel vehicles for public transportation and sanitation industries sold and registered in the city must meet the China VI-b phase standard requirements. 2. M1 category vehicles refer to passenger vehicles with no more than 9 seats including the driver's seat; M2 category vehicles refer to passenger vehicles with more than 9 seats including the driver's seat and a maximum design total mass not exceeding 5000kg; M3 category vehicles refer to passenger vehicles with more than 9 seats including the driver's seat and a maximum design total mass exceeding 5000kg; N1 category vehicles refer to cargo vehicles with a maximum design total mass not exceeding 3500kg; N2 category vehicles refer to cargo vehicles with a maximum design total mass exceeding 3500kg but not exceeding 12000kg; N3 category vehicles refer to cargo vehicles with a maximum design total mass exceeding 12000kg.

What is the situation when a car burns coolant?

There are 5 situations when a car burns coolant: Damaged radiator cap: A damaged radiator cap will leak a large amount of water vapor, leading to coolant loss over time. It is necessary to replace the radiator cap with a new one. System leakage: After prolonged driving, many parts of the car's cooling system may develop leaks, which can cause the car to burn coolant. In this case, it is essential to promptly inspect the sealing condition of each component in the system. Engine overheating: Continuous high temperature and overheating of the engine can cause the coolant to boil and vaporize, leading to a significant loss of coolant through the steam valve of the radiator cap. To prevent engine overheating, it is crucial to add cooling water in time. Low water level: If the car's water level is too low, the cooling efficiency decreases, resulting in the burning of coolant. It is important to ensure the water level is maintained between the maximum and minimum marks when adding water. Non-compliant coolant: When the coolant's boiling point is too low or the evaporation rate is too high, it can lead to burning coolant. It is advisable to use the original manufacturer's coolant for refilling.

What are the differences between a carburetor and electronic fuel injection?

The differences between a carburetor and electronic fuel injection are as follows: Difference 1: Different fuel supply methods: The carburetor mainly relies on the negative pressure in the intake tract to operate, while electronic fuel injection uses the ECU's internal program to control the injector's pulse width to adjust the fuel injection quantity. Difference 2: Different power outputs: The carburetor provides relatively less power; electronic fuel injection delivers relatively more power. The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum created by the engine's operation. As a precision mechanical device, the carburetor uses the kinetic energy of the incoming air stream to atomize the gasoline. Electronic fuel injection is a type of engine that does not require pressing the accelerator when starting. It features cold-start enrichment and automatic fast idle functions, ensuring smooth engine starts whether the engine is cold or warm.

What do fuel consumption A and B mean?

Average fuel consumption A refers to the fuel consumption generated during the current trip, while B represents the fuel consumption per 100 kilometers. Generally, cars display the average fuel consumption, and there is a square button on the upper left side of the dashboard. Pressing this button allows you to view the car's fuel consumption. Typically, the fuel consumption per 100 kilometers is used to judge a car's fuel efficiency. Below is an introduction to Trip A and Trip B: 1. Trip A and Trip B can be freely set. For example: Trip A can be set to reset automatically after each refueling, which means it will clear and restart counting after every fuel fill-up. This is used to track the mileage and fuel consumption for each tank of fuel. Trip B can be set to reset with each vehicle start, which means it will track the mileage and fuel consumption for a single trip. 2. You can also set Trip A and B according to your preferences. By default, they are not linked to any events, meaning they will continue to accumulate the vehicle's mileage and average fuel consumption unless manually reset. For example: If the car has driven 10,000 kilometers since purchase and neither Trip A nor B has been reset, then both will display 10,000 kilometers and the average fuel consumption over that distance.

Is the Highway Toll-Free During Mid-Autumn Festival?

Highway tolls are not waived during the Mid-Autumn Festival. The periods for toll-free highway travel include four national statutory holidays: the Spring Festival, Qingming Festival, Labor Day, and National Day. The toll-free period starts at 00:00 on the first day of the holiday and ends at 24:00 on the last day of the holiday (for highways, the time is based on when the vehicle exits the toll lane). Below is relevant information: On July 24, 2012, the State Council issued the "Implementation Plan for Waiving Toll Fees for Small Passenger Vehicles During Major Holidays." The plan stipulates: 1. Toll-free periods apply during four national statutory holidays: the Spring Festival, Qingming Festival, Labor Day, and National Day, as well as the consecutive holidays determined by the State Council for these statutory holidays in the same year; 2. Vehicles eligible for toll-free travel are passenger vehicles with seven seats or fewer (including seven seats) traveling on toll roads, including motorcycles permitted on ordinary toll roads; 3. The scope of toll-free roads includes those approved in accordance with the "Highway Law" and the "Regulations on the Administration of Toll Highways," encompassing toll bridges and tunnels.
