The reason the red light on the car temperature gauge flashes in winter is: the flashing red light indicates that the coolant temperature has exceeded the specified value, and the vehicle should be stopped immediately. The light will turn off once the temperature returns to normal. The causes of the car temperature gauge alarm are: 1. Lack of antifreeze; 2. The thermostat fails to open properly or is stuck; 3. Reduced water pump efficiency leading to poor water circulation; 4. The cooling fan does not operate properly or runs too slowly when the temperature rises. Solutions for the car temperature gauge alarm are: 1. Lack of antifreeze: Check for leaks, repair, and refill to the correct level; 2. Poor water circulation: If the thermostat fails to open properly or is stuck, it needs to be replaced.

What does GT refer to in cars?

GT is not a specific brand of car, but rather refers to a type of vehicle with certain performance characteristics. GT stands for high-power cars. GT indicates that the car is a high-performance version within its model series. Introduction to GT: GT originates from the Latin term Gran-Turismo, which translates to Grand-Tourer in English. 'Grand' means luxury, and 'Tourer' refers to a traveler or cruiser. Combined, Grand-Tourer essentially means a luxury touring car. Many cars bear the GT badge, such as the Porsche Cayenne GT, Carrera GT, and the 911 GT series. Additionally, manufacturers like Ford, Mercury, and Hyundai also have GT models. Introduction to GT-type cars: GT-type cars are generally referred to as grand tourers or endurance cars, meaning they are capable of long-distance high-speed driving. However, there isn't a single GT-type car called a 'grand tourer' in the world. GT cars are typically high-powered sports cars with a similar appearance—two-door, four-seater (2+2) hardtop coupes with a hatchback.

How often is the vehicle inspected after 6 years?

After 6 years, the vehicle is inspected annually. The Road Traffic Safety Law and its implementing regulations set different inspection cycles based on the vehicle's purpose, type, and age. For small private cars, inspections are required every 2 years within the first 6 years, but the annual inspection sticker must be renewed every 2 years at the vehicle management office. From 6 to 15 years, inspections are conducted once a year, and after 15 years, inspections are required every 6 months. Below is relevant information: 1. New Inspection Rules: The new inspection rules include 7 to 9-seater non-commercial small and mini passenger vehicles (excluding vans) within the 6-year exemption period. For non-commercial small and mini passenger vehicles (excluding vans) older than 6 years but less than 10 years, the inspection frequency is adjusted from once a year to once every two years. 2. Regulations: Article 16 of the Road Traffic Safety Law Implementing Regulations stipulates that motor vehicles must be inspected from the date of registration. Commercial passenger vehicles must be inspected once a year within the first 5 years and every 6 months thereafter. Trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years and every 6 months thereafter.

What Parts of a Car Can Be Modified?

Modifications can be made to a car's exterior, wheels, interior, etc. Vehicle Exterior: First is the modification of the vehicle's exterior, which mainly includes changing the body color or applying body wraps. However, the vehicle must be registered with the local vehicle management office within 10 days after changing the color, and new photos must be taken for the vehicle registration certificate along with updating the license. Note that the following three colors are not allowed to be changed: fire engine red (R03 bright red), administrative law enforcement vehicle colors (white top with blue bottom), and engineering rescue yellow. Wheels: When modifying wheels, it's important to note that the size of the rims cannot be altered, as changing the rim size affects the car's power and performance and is considered illegal. However, rims of the same size can be replaced. Interior: Interior modifications are theoretically allowed as long as they do not affect safe driving. However, seats cannot be removed or added without authorization, and the structural characteristics registered with the vehicle management office must not be altered. Another common modification is upgrading the car's audio system. Currently, full audio system upgrades are popular in the market. Modifying the audio system does not affect the overall functionality of the vehicle and is within the permissible limits.

Does the Dash Cam Work When the Car is Not Started?

When the car is not started, the dash cam can still record videos if it relies on its built-in battery for power. However, the recording time is relatively short. Typically, the battery can only sustain standby for about four to five hours, and some dash cams with low-capacity batteries may only last around half an hour, making it unsuitable for prolonged recording. If the dash cam is powered by the car battery, it can continue recording even when the car is not started, as long as the dash cam is not turned off. However, this will continuously drain the car battery, potentially leading to a dead battery. Most dash cams come with a parking monitoring feature. Dash cams equipped with this function can continue recording after the car is parked. This monitoring feature generally falls into two categories: continuous recording and motion-activated recording. Continuous recording: After the car is turned off, the dash cam can maintain 24-hour recording, provided it has a sufficient power source. This usually requires connecting to a continuously powered part of the car to sustain long-term operation. Relying solely on the built-in battery will not last long, and the dash cam will shut down once the battery is depleted. Motion-activated recording: This mode typically activates short-duration recording only when the car experiences vibrations after being parked, such as during a collision or when objects move in front of the car. This helps conserve the battery's power.

Can China V Vehicles Not Be Licensed Nationwide?

China V vehicles can be licensed in some areas, such as Guangdong (except Guangzhou), Jiangsu (except Nanjing), Zhejiang (except Hangzhou), Sichuan (except Chengdu), Fujian, Guangxi, Ningxia, Hunan, Hubei, Xinjiang, and Yunnan, etc. Documents required for licensing China V vehicles: Original copy of the "Motor Vehicle Registration, Transfer, Cancellation/Inbound Application Form". Original and photocopy of the vehicle owner's ID card, original and photocopy of the driver's license. Original or original and photocopy of the proof of vehicle ownership transfer. For imported vehicles, the original customs-approved transfer certificate is also required. Original vehicle inspection record form, vehicle registration certificate, and standard vehicle photos. For proxy applications, a "Power of Attorney" and the agent's identity proof are also needed. Licensing process: Bring the above materials to the relevant DMV window to complete the procedures. A transfer specialist will inspect the vehicle, take rubbings, photos, and remove the license plate. After the vehicle passes inspection, you can go to the hall to select a license plate number (20 options, 3-minute selection time). Finally, a temporary license plate will be issued, and the official license plate is usually issued within 3-5 working days. After replacing the driving license and updating the registration certificate information, the vehicle can be driven on the road.

What does first gear, second gear, third gear, and fourth gear mean on a motorcycle?

Low gears are for low speeds, and high gears are for high speeds. First gear: starting from 0-20-30, second gear: 20-30-40-50, third gear: 30-40-50-60-70, fourth gear: 40-50-60-70-80. Below is some relevant information: 1. Speed requirements: The displacement must meet the standard. Highways have clear speed regulations, with the maximum speed for cars being 120 km/h, but motorcycles on highways must not exceed 80 km/h, and the minimum speed must not be below 60 km/h. This can indeed be challenging for motorcyclists who are not adept at controlling their speed. Within this speed range, there is only a fluctuation of 20 km/h, making it easy to either exceed the speed limit or fall below the minimum speed limit if not careful. 2. Precautions: Before setting off, always ensure that the motorcycle's fluid levels are correct. Typically, the status of the engine oil and coolant can be easily checked via the dashboard indicators, while the brake and clutch fluid levels need to be observed from specific positions. Special attention should be paid to the coolant level in the radiator during summer.
