What does the flashing 'security' light mean?

When the 'security' light flashes in a car, it may be reminding the driver to fasten their seatbelt. Simply fastening the seatbelt should resolve the issue. The 'Security' light is a safety reminder light, typically symbolized by an airbag, a human figure, or a seatbelt. This safety light is also part of the anti-theft system. When the 'security' light is on, it indicates that the car's anti-theft system is in a locked state, primarily designed to prevent theft of the vehicle or items inside. Below is an introduction to the car's anti-theft system: 1. Meaning: The car anti-theft system is designed to prevent theft of the vehicle or items inside. 2. Main function: It prevents unauthorized use of the vehicle's own power to steal the car, i.e., prevents illegal engine starting. 3. Importance and composition: The vehicle anti-theft system and the engine immobilizer system are essential for vehicle security. The anti-theft system consists of an electronically controlled remote or key, electronic control circuit, alarm device, and actuators.

Is driving at 80 in a 70 speed limit zone considered speeding and will points be deducted?

Driving at 80 in a 70 speed limit zone is considered speeding and points will be deducted. According to the new traffic regulations, driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles on highways or urban expressways at speeds exceeding 20% above the speed limit, or driving other motor vehicles at speeds exceeding 50% above the speed limit, will result in 12 points being deducted. The following are the penalties for speeding: 1. Speeding within 10% of the speed limit: 3 points deducted. 2. Speeding between 10% and 20% above the speed limit: 3 points deducted. 3. Speeding between 20% and 50% above the speed limit: 3 points deducted. 4. Speeding between 50% and 70% above the speed limit: 6 points deducted, and the driver's license may be revoked. 5. Speeding 70% or more above the speed limit: 6 points deducted, and the driver's license may be revoked.

What is the deadline for a car's semi-annual inspection?

Car semi-annual inspection deadline is small cars after 15 years require semi-annual inspections. For small and mini non-commercial passenger vehicles, inspections are required every 2 years within the first 6 years, annually after exceeding 6 years, and every 6 months after exceeding 15 years. Below is an introduction about vehicle inspections: 1. Introduction: It refers to the annual motor vehicle inspection. The vehicle inspection process is the fixed procedure for annual vehicle checks. 2. Regulations: If a vehicle is found by traffic police without annual inspection, the owner will be fined or the vehicle may be impounded. Meanwhile, in insurance contracts, vehicles that fail timely annual inspections are considered unqualified, and no claims will be paid in case of accidents. 3. Content: Check whether the engine, chassis, body and its accessories are clean, complete and effective, whether the paint surface is uniform and aesthetically pleasing, whether major assemblies have been replaced, and whether they match the initial inspection records.

What are the symptoms of tire cupping?

Tire cupping symptoms include uneven wear on one side of the tire or irregular patchy wear patterns on the surface. Causes of tire cupping: 1. Incorrect toe adjustment, causing the vehicle to pull to one side and feel unstable at high speeds; 2. Failed tire dynamic balance, resulting in irregular patchy wear on the tire surface, often accompanied by vehicle vibration at certain speeds. Solutions for tire cupping: 1. For incorrect toe adjustment and misaligned wheel camber, the issue can be resolved by adjusting the length of the steering tie rod; 2. For failed tire dynamic balance, it's necessary to adjust the suspension angles on a wheel alignment machine and perform tire dynamic balancing. Due to manufacturing processes or external factors, the mass distribution of a wheel may become uneven. When the wheel rotates at high speed, this creates dynamic imbalance. To prevent or correct this condition, counterweights are added to the wheel during dynamic balancing to equalize the mass distribution around the wheel's edges, thereby preventing tire cupping.

Is the Displayed Fuel Consumption on Cars Accurate?

The displayed fuel consumption on cars is generally accurate. Below is an introduction about car dashboards: 1. Introduction: The instruments on different car dashboards vary, but the common instruments in most cars include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. 2. Condition: In modern cars, a voltage regulator is also installed on the dashboard to stabilize the voltage of the dashboard power supply, suppress fluctuations, and ensure the accuracy of the car instruments. 3. Development: Additionally, most instrument displays rely on sensors. The sensing device changes its resistance value based on the state changes of the monitored object, which is then displayed on the dashboard. The most prominent instrument on the dashboard is the speedometer, which indicates the car's speed in km/h (kilometers per hour). The speedometer actually consists of two gauges: one is the speed indicator, and the other is the odometer.

What is SF15W-40 engine oil?

SF is the grade designation of engine oil, and 15W-40 is the viscosity rating of the oil. Engine oil grades range from "SA" to "SN", with each subsequent letter indicating better performance and more additives to protect the engine. The further the letter is in the alphabet, the higher the quality grade. International brands often have oil grades above SF. 15W-40 is the viscosity rating of the oil. Below is some relevant information about engine oil: 1. Function of engine oil: Engine oil lubricates and reduces wear, assists in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. It is known as the "blood" of a car. Choosing the right oil and changing it regularly can maintain the engine in good condition and extend its service life. 2. Choosing engine oil: The best oil is not necessarily the most expensive; it should be selected based on the characteristics of the car's engine and driving habits. It can also be categorized by winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, oils with better low-temperature viscosity grades are not necessary.
