Should Vehicle Maintenance Be Based on Mileage or Time?

Whether to perform maintenance based on time or mileage generally follows the principle of whichever comes first. There is no fixed answer, as car owners need to analyze their vehicle's specific conditions to determine the optimal approach. Here is a brief introduction to vehicle maintenance: (1) Routine Maintenance: Typically performed every 5,000KM (or 7,500KM for some models), it mainly involves changing the engine oil and oil filter, inspecting the fuel filter (many modern vehicles no longer have one), and checking the air filter—replacing them if excessively dirty. Additionally, each maintenance session must include an inspection of the brake discs and pads for potential replacement, checking the brake fluid level, and assessing tire conditions to ensure safety. (2) Periodic Maintenance: Usually conducted every 3 years or every 40,000KM. Beyond routine maintenance, it includes cleaning the fuel injectors, throttle body, and the vehicle's intake system. Furthermore, it requires replacing transmission fluid, front and rear axle oil, coolant, and brake fluid. Tire wear should also be inspected, with replacements made if necessary. (3) Major Maintenance: Typically occurs after the vehicle has traveled 100,000KM, involving a comprehensive inspection and replacement of parts as needed. Special attention should be paid to the wiring (electrical circuits) and transmission mechanisms during this phase.

What Are the Reasons for No Hot Air in a Car?

Car no hot air reasons are as follows: 1. Thermostat failure, causing the cooling system to prematurely enter a large circulation cycle resulting in no hot air. 2. Dirty or clogged air filter, affecting the effectiveness of the hot air. 3. Broken heater control button, unable to transmit the corresponding hot air supply signal, leading to no warm air. 4. Clogged heater core, preventing coolant from passing through the small radiator resulting in no hot air. Below is the principle of car hot air: When the car air conditioning is heating, the high-temperature coolant from the engine flows through the heater core. At this time, the air blown by the blower also passes through the heater core, allowing the car air conditioning vents to blow out warm air.

What does VSC on a car mean?

The VSC on a car refers to Vehicle Stability Control, which translates to Body Stability Control System in Chinese. It is an active safety system developed by Toyota Motor Corporation, consisting of a converter composed of devices with turn-off capability (such as Insulated Gate Bipolar Transistors (IGBT)). The VSC system has three main features: (1) Real-time monitoring: The VSC system can monitor the driver's control actions (steering, braking, throttle, etc.), road conditions, and the vehicle's motion status in real time, and continuously sends commands to the engine and braking system. (2) Active intervention: Safety technologies like ABS mainly intervene in the driver's actions but cannot regulate the engine. The VSC system, however, can actively adjust the engine throttle to control engine speed and adjust the driving and braking forces on each wheel to correct oversteering and understeering. (3) Prior warning: When the driver operates improperly or the road conditions are abnormal, the VSC system will alert the driver with a warning light.

Can a C1 license drive a 9-seater vehicle?

C1 driver's license can drive small passenger vehicles with 9 seats or less (including 9 seats). The permitted driving scope of a C1 driver's license includes small and mini passenger vehicles, light and mini cargo vehicles, and light, small, and mini special-purpose vehicles; small passenger vehicles accommodate 9 or fewer people. C1 driver's license cannot drive: large buses, tractors, city buses, medium-sized buses, large trucks, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license cannot drive vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

How to Fix a Twisted Seat Belt?

Solution for a twisted seat belt: Remove the trim panel on the B-pillar inside the car, unscrew the seat belt mounting bolt, straighten the seat belt, and then tighten the bolt and reinstall the trim panel. The critical importance of seat belts for travel safety is self-evident. When there is an issue with the seat belt, it should be taken seriously. Before traveling, inspect the seat belt to ensure it functions properly. Below are some precautions regarding seat belt usage: 1. Correct use of seat belts: The seat belt should be fastened across the hips and chest, forming a horizontal V-shape over the pelvis and ribcage. It should only be used by one person; sharing is strictly prohibited, and the seat belt should not be twisted during use. 2. Seat belt status when not in use: When no one is seated, the seat belt should be retracted into the reel, and the buckle should be placed in the storage position to prevent it from hitting other objects during emergency braking. 3. Pay attention to seat angle: Do not tilt the seat back too much, as this may affect the effectiveness of the seat belt. Ensure the buckle is securely fastened to prevent it from coming loose under force and failing to provide protection.

What is the difference between built-in and external tire pressure monitoring?

Tire pressure monitoring built-in vs. external differences: 1. Price: Built-in types are relatively more expensive than external types. 2. Installation method and time required: Installing built-in tire pressure monitoring takes more time and requires professional tire removal; external installation is relatively simpler. Tire pressure monitoring is generally divided into the following two types: 1. Direct tire pressure monitoring: Uses pressure sensors installed in each tire to directly measure tire pressure, and wireless transmitters to send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data. When tire pressure is too low or there is a leak, the system automatically alerts. 2. Indirect tire pressure monitoring: When the pressure of a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making its rotation speed faster than other wheels.
