The SVS on the dashboard is a fault indicator light, which is illuminated by the ECU or TCU of an electronically fuel-injected car when it detects a problem with the engine or automatic transmission. All electronically fuel-injected cars have an SVS fault indicator light. For manual transmission models, it serves as the engine fault indicator light, while for automatic transmission models, it indicates both engine and automatic transmission faults. More information about the SVS light is as follows: 1. The SVS light is a standard indicator in the automotive industry, responsible for warning of abnormalities in the powertrain system and prompting users to have the vehicle serviced. When the powertrain system's self-diagnosis detects an abnormality, the SVS light will alert the user to service the vehicle. 2. The SVS light alarm may originate from the engine, transmission, or gear shift mechanism. When the SVS light flashes, it indicates a current fault in the powertrain system that requires servicing. The car's SVS light is similar to the engine fault light. When the SVS indicator is on, it means the engine control unit has detected an erroneous signal from a sensor or that a component has exceeded its usage standard. 3. When the ignition is turned on, the car's SVS indicator light will illuminate for an automatic check and will turn off automatically after a few seconds.

Last time I drove that old Jetta, the SVS light also came on. At first, I thought it was some major issue. Turns out, it was just the car telling me, 'Time for maintenance!'—sometimes it’s like a phone popping up an update reminder. But you gotta pay attention: if it lights up together with the yellow check engine light, it’s probably the exhaust system acting up—especially with China-6 cars, a clogged particulate filter is the most common culprit. You can still drive to the repair shop with this light on, but if it turns red, you gotta pull over immediately and call for roadside assistance.

Maintenance content: According to the official maintenance manual, it is recommended that the owner perform the first maintenance when the vehicle reaches 5,000 kilometers, including replacing the engine oil and oil filter. After that, it is recommended to perform regular maintenance every 10,000 kilometers. In addition, the air conditioning filter is recommended to be replaced every 20,000 kilometers; the air filter is recommended to be replaced every 20,000 kilometers or 2 years (whichever comes first); the spark plugs are recommended to be replaced every 30,000 kilometers; the automatic transmission and manual transmission are recommended to be checked at 60,000 kilometers and replaced if necessary, while the gasoline filter is recommended to be replaced every 60,000 kilometers; the timing belt is recommended to be checked for the first time when the vehicle reaches 90,000 kilometers, and then every 30,000 kilometers thereafter, and when the vehicle reaches 180,000 kilometers, the timing belt must be replaced; the brake fluid is recommended to be replaced every 24 months. 2. 4S shop maintenance cycle: From our actual visits to 4S shops for investigation, the maintenance cycle set by 4S shops will be based on the actual local driving conditions, and there may be differences in the maintenance cycle of some parts compared to the official manual. In addition, according to the after-sales personnel of 4S shops, the maintenance cycle and cost of the new Jetta 1.4L and 1.6L models are the same.

Does Rain Affect the Car Film After Application?

Rain does not affect the car film after application. Since the car film is typically applied to the interior side of the windows, as long as you do not roll down the windows during rain, it will have no impact on the film. Car wrap films are used to cover the entire vehicle or specific parts with colorful and diverse films to alter the appearance. These films adhere to the car's surface through polymer materials and can be easily removed. You can also wash your car after a full-color wrap, but it's best to wait at least a week to ensure the film is not affected, as all films are waterproof. However, avoid washing or wetting the film immediately after application. Hand washing is recommended to prevent any damage to the film's effectiveness. Generally, it's advisable to apply the film on rainy or cloudy days when there is less dust in the air and no direct sunlight, allowing the film to adhere better to the car's surface. However, before changing the car's color entirely, you must report it to the vehicle management office to avoid any legal issues. The film does not dry immediately after application, so avoid washing the car or rolling down the windows for at least a week to prevent issues like bubbling or poor adhesion. Proper maintenance is essential after applying the car film.

What are the symptoms of excessive refrigerant in car air conditioning?

Symptoms of excessive refrigerant in car air conditioning: 1. The suction and discharge pressures of the air conditioning system are too high, and the equipment operates at elevated temperatures; 2. The current value of the compressor power supply is significantly higher than normal, and prolonged operation may burn out electrical components; 3. The condenser is filled with refrigerant, reducing the heat exchange area, leading to high-pressure protection phenomena after the car air conditioning is turned on. Car air conditioning is designed to regulate and control the temperature, humidity, and air cleanliness within the enclosed space of a vehicle. The role of the air conditioning refrigerant is to lower the temperature of the air inside the car. The refrigerant absorbs heat from the cooling medium in the evaporator and then transfers the heat to the surrounding air or water in the condenser, where it condenses.

Can Fully Synthetic and Semi-Synthetic Engine Oils Be Mixed?

Fully synthetic and semi-synthetic engine oils should not be mixed. Semi-synthetic oil is a lubricant formulated from Group III base oils, while fully synthetic oil is produced by chemically decomposing various natural substances and then synthesizing them with other materials. Fully synthetic oil is superior to semi-synthetic oil, offering a longer replacement interval and better engine protection. Hazards of mixing different grades of engine oil: 1. Abnormal exhaust pipe smoke; 2. Accelerated sludge buildup; 3. Reduced sealing performance of piston rods or piston rings, leading to discoloration or damage; 4. Engine malfunctions; 5. Severe wear of pistons and cylinder walls.

Which province does the license plate starting with 'Hong' belong to?

As of now, there is no license plate in China that starts with the character 'Hong'. The first character of a license plate is a Chinese character representing the provincial-level administrative region where the vehicle is registered, which is the abbreviation of provinces, municipalities directly under the central government, and autonomous regions. The second character is an English letter, representing the prefecture-level administrative region where the vehicle is registered, which is the letter code for prefecture-level cities, regions, autonomous prefectures, and leagues. The combination of numbers and letters in the license plate serial number should be used in an orderly manner according to regulations. When the usage rate of the serial number exceeds 60%, the next combination method should be enabled in sequence after approval by the provincial public security traffic management department and reported to the Traffic Management Bureau of the Ministry of Public Security for record.

What Do Tire Pressure Monitoring Data Represent?

Tire pressure monitoring data represent the air pressure of each tire. The recommended tire pressure should be between 220kPa and 280kPa. Pressures above 300kPa may increase the risk of a blowout, while pressures below 200kPa can lead to abnormal tire wear. Methods to check tire pressure monitoring data include: 1. Using a tire pressure monitor; 2. Detecting tire pressure changes through navigation; 3. Pressing the tire pressure monitoring button in the central control panel area. Tire pressure monitoring automatically and continuously measures tire pressure while driving, alerting the driver to leaks or low pressure to ensure driving safety. The system works by using pressure sensors installed in the tires to measure air pressure, then transmitting this data wirelessly from inside the tire to a central receiver module.
