Should the Air Conditioning Be Turned Off When the Engine Is Off?

Where is the hood switch for Haval?

The switch is located at the lower left side of the driver's compartment. Here is more information about Haval vehicles: 1. Introduction: Haval is a sub-brand of Great Wall Motors, established on March 29, 2013. As an SUV-focused brand, Haval operates in parallel with the Great Wall brand, using independent logos, product development, production, and service systems. It mainly engages in SUV production and sales. The brand includes three series: H, M, and F. 2. Product Planning: Haval has set a detailed product plan. Currently, the H5 and H6 models are available for sale. In the next two years, eight SUV models from H2 to H9 will be launched, forming the product lineup of the Haval brand. Even-numbered models are positioned as urban SUVs, including H2, H4, H6, and H8; odd-numbered models are positioned as off-road SUVs, including H3, H5, H7, and H9. The Haval H9 will be a full-size SUV model, expected to be launched next year, while the new H2 and H8 will be released within this year.

How Much Fuel Should Be Put in a Car's Gas Tank?

The volume marked on the fuel tank is not the actual maximum volume, but the maximum reasonable volume. A standard fuel tank can hold 10% to 15% more gasoline or diesel than the marked volume. For example, a 60-liter fuel tank can hold up to 75 liters. Here is some relevant information about the accuracy of fuel quantity: 1. It cannot be determined based on the rated capacity of the fuel tank. A car fuel tank is a container (not classified as a measuring instrument by the state) and cannot be used as a basis for judging measurement accuracy. According to mandatory national standards, the rated capacity of a car fuel tank should be controlled at 95% of the maximum safe capacity. 2. It cannot be determined based on the fuel gauge on the car dashboard. Most car fuel gauges operate via a float inside the tank that moves up and down, driving an electronic sensor. The sensor sends an electronic signal to the fuel gauge needle, which displays the reading on the gauge. However, the error margin is significant, and the markings on the fuel gauge cannot accurately reflect the actual fuel level in the tank.

What Causes the Abnormal Noise When Turning the Steering Wheel?

Abnormal noise when turning the steering wheel may be caused by wear in the CV joint. The solution involves disassembling and inspecting the inner walls of the left and right inner CV joints for wear and indentations. In most cases, the issue arises from indentations caused by wear on the inner walls of the CV joints, specifically at the points where the outer surface of the ball bearings frequently contacts during torque transmission (load-bearing points). Another possible cause is the sound of the turn signal rebound clip. This typically produces three clicking sounds per full rotation of the steering wheel. Below are some related explanations: 1. Noise from the steering column dust cover. If you hear noise coming from below the steering wheel whenever you turn it, whether stationary or moving, you should check the steering column dust cover. 2. Noise due to interference with the clock spring (spiral cable). If the noise comes from inside the steering wheel when turning, this is often caused by interference with the clock spring (spiral cable) inside the steering wheel. 3. Noise from the shock absorber top bearing. If the noise seems to come from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. 4. If the noise is not from the shock absorber's top bearing, check whether the stabilizer bar bushings are loose or damaged.

What does RCD mean?

Introduction to the meaning of RCD: 1. In building electrical systems, RCD refers to Residual Current Device, which primarily functions to prevent fires and equipment damage caused by electrical leakage. 2. RCD can also stand for Room Temperature Catalytic Decomposition, which involves the long-term stable catalytic oxidation of formaldehyde pollutants in the air into water and carbon dioxide using ambient heat at room temperature. A Residual Current Device (RCD) is a type of leakage protection device. Leakage protection devices are low-voltage safety protection appliances with the following functions: 1. Preventing single-phase electric shock accidents caused by leakage; 2. Preventing fires and equipment damage caused by leakage; 3. Detecting and interrupting various single-phase ground faults; 4. Some leakage protection devices can also provide overload, overvoltage, undervoltage, and phase-loss protection.

Why Did Jetta Change Its Logo?

Here is the relevant introduction about Jetta changing its logo: 1. Volkswagen wants to complete the high, medium, and low brand lineup: FAW-Volkswagen's high-end brand is Audi, the mid-range brand is Volkswagen, and the Jetta car is the cheapest within the Volkswagen brand, targeting the low-end market around 100,000 yuan. Therefore, to compete in the low-end market in the future, a new brand needed to be established. 2. Competing with SAIC Volkswagen's Skoda brand: Currently, SAIC Volkswagen's more low-end brand is Skoda, which originates from a Czech car brand. 3. Introducing the SEAT brand into the domestic market: From the three models exposed by the Jetta brand, the new cars under the Jetta brand are actually SEAT models from abroad. Since SEAT has very low recognition in China, the cost of re-promotion is high. Therefore, SEAT might be promoted under the Jetta brand.

Is It Normal for New Car Brake Discs to Rust?

For most household cars, brake disc rust is a very normal phenomenon and is not a standard for checking whether a car is new or not. Whether the brakes are prone to rust mainly depends on the material of the brake discs. Currently, most household cars use brake discs made of gray cast iron 250 standard. Although they provide good braking performance, they have a high carbon content and no surface rust protection, making rust inevitable. Here is some related information about car brake disc rust: 1. Brake discs are exposed to the outside and are in constant contact with mud, rainwater, and moisture in the air. If the car is not driven for a few days, the brake discs will start to rust. Even newly replaced brake discs can rust overnight in humid weather. Minor rust generally does not affect braking performance. In fact, simply driving the car and applying the brakes a few times can remove the rust. 2. If the car is left unused for a long time and the brake discs become severely rusted, it is important to clean them. This is because car braking relies on the friction between the brake pads and the brake discs. If the rust on the brake disc surface is too thick, it will not provide effective braking, inevitably increasing the braking distance. Additionally, friction between the brake pads and rust is unstable, often causing the brake pedal to vibrate and produce harsh noises, which also accelerates wear on the brake pads.
