What Does the Brake System Warning Light Mean?

What is the reason for the constant yellow light on the Haval SS?

If the yellow light on the Haval SS remains illuminated for an extended period, it indicates that the intelligent start-stop system is activated, but the current conditions do not allow for intelligent start-stop. Below is an introduction to the intelligent start-stop system: 1. The start-stop system pauses the engine (instead of maintaining traditional idling) when the vehicle is stationary (not in park mode), while the engine's lubrication system continues to operate, ensuring internal lubrication. 2. If the vehicle remains stationary for too long, causing the AGM battery to have insufficient charge, the yellow "ECO" light on the right side of the dashboard will also illuminate. The vehicle will automatically disable the start-stop system until sufficient power is restored, at which point the green "ECO" light will illuminate, and the system will resume operation.

How to Check the Mileage on a Mercedes-Benz?

The method to check the mileage on a Mercedes-Benz is: You can view the mileage in the trip section of the central dashboard. To check the mileage for a single trip, swipe right from the left side of the steering wheel, then select the information on the right side of the dashboard and scroll up or down. Taking the Mercedes-Benz GLS as an example, its dimensions are 5130mm in length, 1934mm in width, and 1860mm in height, with a wheelbase of 3075mm. In terms of exterior design, the Mercedes-Benz GLS adopts the brand's family-style design language, featuring the iconic double-slat grille at the front, paired with a honeycomb mesh and the Mercedes-Benz logo. For the suspension system, the Mercedes-Benz GLS uses double-wishbone independent suspension at both the front and rear.

What are the types of steering systems?

There are three types of steering systems: mechanical power steering system, electro-hydraulic power steering system, and electric power steering system. The mechanical power steering system uses the driver's physical strength as the steering energy source, and all the force-transmitting components are mechanical. The mechanical steering system consists of three major parts: the steering control mechanism, the steering gear, and the steering transmission mechanism. In the electro-hydraulic power steering system, the steering oil pump is no longer directly driven by the engine but is driven by an electric motor, and an electronic control system is added on top of the previous setup, making the steering assist force not only related to the steering angle but also to the vehicle speed. The mechanical structure includes added hydraulic reaction devices and fluid distribution valves, while the new electronic control system includes vehicle speed sensors, solenoid valves, steering ECU, etc. The electric power steering system can provide variable assist, which requires a complex balance between power and control. The electric power steering system is replacing the hydraulic power steering system as the mainstream steering system in automobiles.

What are the common units for car tire pressure?

Tire pressure is generally measured in five units: kg/cm2, bar, Kpa, Psi, and atmospheric pressure. According to the international standard GBT2978-2008, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; The maximum pressure should not exceed 3.5bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can be about 0.1bar lower than the standard to prevent tire blowouts due to high temperatures.

What Type of Fire Extinguisher Should Be Used in a Car?

For cars, it is recommended to use a dry powder fire extinguisher. Below is an introduction to dry powder fire extinguishers: 1. There are two types of dry powder: regular and ultra-fine, with the same principle but differing as the names suggest. When the dry powder is sprayed onto flames or combustible surfaces, the ammonium phosphate in it forms a crystalline coating. This substance undergoes a secondary reaction with the free radicals produced during combustion, which helps dilute oxygen, isolate air, and provide a cooling effect. 2. Nitrogen is the power source of dry powder fire extinguishers. Nitrogen is injected into the steel cylinder at a pressure higher than normal atmospheric pressure. When the nozzle is opened for use, the pressure is released, and the dry powder is expelled along with the nitrogen. Nitrogen does not support combustion and has a certain heat-absorbing effect. The temperature that engine pistons can withstand is only about 600 degrees Celsius, while gasoline burns at 1200 degrees. Part of this heat is converted into internal energy, and another portion is absorbed by the nitrogen in the air.

Can a Brand New Car Be Driven on the Highway?

A brand new car can be driven on the highway. Here are more details: 1. The break-in period for a new car is approximately the first 2,000 kilometers. During this period, it's not advisable to complete the entire break-in process solely on regular roads or exclusively on the highway. High-speed driving helps in breaking in the higher gears, while lower gears also require their own break-in period. 2. Modern car manufacturing processes are quite advanced, with high machining precision. However, a break-in period still exists, though it's not as critical as before. 3. The vehicle maintenance manual that comes with the car provides clear guidelines on the proper usage of a new car, including speed limits and load capacity. Therefore, while new cars do have a break-in period, the focus nowadays is less on the mechanical components breaking in and more on the driver getting accustomed to the car's characteristics. The most important aspect is for the driver to become familiar with and adept at handling their new vehicle.
