What to Do When the Car Sunroof Won't Close?

Under what circumstances should the car ECO mode be used?

The car ECO mode is turned on and used in urban congested road conditions, and the fuel-saving effect is good after turning on the ECO mode. Under the operation of the ECO mode, the carbon deposits in the engine are basically the same as those produced by the engine in the normal working mode. The main principle of the ECO mode is not complicated. It mainly involves a comprehensive judgment and analysis of factors that affect fuel consumption during vehicle movement, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the appropriate amount of fuel to be supplied to the engine for operation, effectively reducing fuel consumption compared to the normal driving mode. Simply put, it controls the engine speed with reasonable gears to reduce unnecessary fuel consumption. ECO is an abbreviation, and the Chinese translations are Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is also divided into active eco-driving mode and non-active eco-driving mode. When the ECO indicator light on the dashboard lights up, it means the car's economic mode has been activated. The eco mode is divided into active and non-active types. The difference is that the active type has its own button, and the owner can choose whether to turn it on. When the owner presses the eco mode switch, the dashboard indicator light will light up, and the vehicle will automatically start adjusting settings, such as throttle opening, transmission shift logic, and air conditioning output power. The non-active eco mode does not have a dedicated button. When the dashboard eco indicator light is on, it is only a reminder function. The eco mode will automatically evaluate your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the eco indicator light. Most cars use the active eco-driving mode, which means they have their own switch button. Therefore, during daily driving, we can turn on the eco mode. However, it is not necessary to turn on the eco mode when the speed exceeds 120 mph, during idle parking, in N/P gear, or in manual mode, especially when climbing a hill, as this would not reflect the economic and fuel-saving characteristics of the eco mode. In addition, the eco mode usually fails under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car will consider the speed, and the eco mode will automatically fail. During idle parking or in N/P gear and manual mode, the eco mode may also fail. When a large torque output is required, such as when climbing a hill, the engine computer will prioritize ensuring sufficient power to drive the vehicle, and the eco mode will not work either.

What is a tire pressure gauge?

A pressure gauge is an instrument used to measure air pressure, among which a tire pressure gauge is specifically designed for measuring the air pressure in tires. It consists of a gauge head, piston, main spring, etc. The gauge head has only one pressure measurement port, featuring a simple structure, small range, high accuracy, and ease of use. It is suitable for measuring tire pressure in small vehicles such as micro cars and motorcycles. Place on level ground: The vehicle should be parked on level ground, and tire pressure must be measured when the tires are cold. Remove the valve cap: Remove the tire's valve cap and press the measuring nozzle of the tire pressure gauge vertically onto the tire's valve stem. The pressing speed should be quick to prevent air leakage from the tire. Check requirements: Compare the measured tire pressure with the recommended pressure listed on the vehicle's door panel and consider the driver's experience to determine if the tire pressure meets the requirements. If the tire pressure is too high, the gauge can be used to release air. If the tire pressure is too low, immediately use an onboard air pump to inflate the tire to the safe pressure level and re-measure to verify the accurate pressure. Inspection cycle: Check the tire pressure at least once a month. Before becoming proficient in measuring tire pressure, take multiple measurements to ensure the readings are accurate.

Where is the motor number in front of the engine number?

The location of the car engine number is: Engine cylinder block: The engine model is printed on the engine cylinder block, on both sides at the rear of the cylinder block. Sometimes the location is not visually visible, and a lift is required to see it. Vehicle license: The vehicle license also indicates the engine model, which includes the engine number, and can be viewed there. Rubbing the engine number: To rub the engine number, first place a white paper over the engine number and frame number, then gently rub horizontally with a pencil to obtain the required number imprint. Cut it out and paste it onto the registration form with glue.

Which Vehicles Do Not Require a Driver's License?

Low-speed electric vehicles do not require a driver's license. Golf Carts: Golf carts and modified versions. Used in golf courses, company warehouses for transporting goods, construction sites, and household purposes. Sightseeing vehicles and vintage cars, for example, those used in tourist areas with speeds of 20-30 km/h or for security patrols in residential communities. Nationwide, led by Marshell Electric Vehicles, there are approximately over 200 manufacturers producing around 10,000 units annually. Japanese Regulations: The maximum speed of low-speed electric four-wheelers should not exceed 50 km/h; the body length should not exceed 3400 mm, and the body width should not exceed 1300 mm. EU and Other Countries: These vehicles are registered under license plates different from traditional cars, and owners can enjoy benefits such as purchase subsidies, exemption from annual inspections, and toll exemptions. In Europe, some countries have designated specific roads for low-speed vehicles.

Can the duplicate page of the vehicle license be reissued separately?

Bring your ID card and a copy, drive the vehicle directly to the vehicle management office for reissuance. The specific process is as follows: inquire at the front desk to get a number; take your ID card to the registration point to get a form; submit the form, take photos, and get the form at the vehicle inspection area; pay the fee at the payment window; wait at the collection window with your ID card to receive the new vehicle license. Introduction 1: To reissue the vehicle license, you must also submit a standard photo of the vehicle. You can prepare it in advance. The vehicle image should occupy two-thirds of the photo, clearly showing the body color and appearance features, taken from a 45-degree angle on the left front side of the vehicle. Introduction 2: According to Article 25, Paragraph 1 of China's "Procedures for Handling Road Traffic Safety Violations": If the vehicle license is not carried (or the license is incomplete, missing the duplicate page), the vehicle can be legally detained. Introduction 3: The original and duplicate pages of the vehicle license are indispensable components. The original page records the basic information of the vehicle, while the duplicate page records the inspection status of the vehicle. Even if only the duplicate page is lost, it must be reissued.

What are the differences between National V and National VI emission standards for sedans?

The differences between National V and National VI emission standards are as follows: Different emission standards: The National VI emission standards are more than 30% stricter than National V. Excluding the influence of operating conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The National V standard was implemented nationwide on January 1, 2017, as the fifth phase of national motor vehicle emission standards. The National VI standard has been implemented since July 1, 2019. Different principles: During the National V phase, diesel and gasoline vehicles had different emission standards, but National VI adopts a fuel-neutral principle, meaning that regardless of the fuel type, the emission limits are the same. Different issuing departments: The National V standard was issued by the Ministry of Environmental Protection. The National VI standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: National V is represented by 'V,' while National VI is represented by 'VI.' Different monitoring requirements for plug-in hybrid electric vehicles: Compared to National V, National VI has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulatory aspects. National V standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. National VI has two standards: National VIa and National VIb, as follows: National VIa standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. National VIb standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM (particulate matter) per kilometer driven. Affected by the National VI emission policy, although National V vehicles are not currently restricted in normal use (no driving bans or license plate restrictions), their resale value will be significantly impacted. For car owners, if they purchase a truck for hauling goods with a loan, the vehicle's depreciation after repaying the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, National VI vehicles, with longer service life and more road rights, have greater advantages.
