Can You Still Drive When the Airbag Light Is On?

You can still drive when the airbag warning light is on, but it is not recommended: 1. The airbag light may indicate a false fault. If the car battery is low or other electrical devices in the vehicle are damaged, it could affect the airbag's feedback voltage. 2. If road conditions permit, you can temporarily park in a safe place when the airbag warning light is on, turn off the engine, disconnect the negative terminal of the battery, wait for 5-10 minutes, then reconnect it and restart the engine to complete the vehicle self-check. If the airbag indicator disappears, you can continue driving; if it remains lit, you should go to the nearest repair shop for maintenance.

How to Change a Flat Tire?

Here are the steps to change a spare tire: 1. Remove the damaged tire: Use a wrench to loosen the bolts, but do not remove them completely at this stage—just loosen them. 2. Lift the car with a jack: Ensure the jack is positioned correctly and lift the car just enough to remove the tire. Then, install the spare tire by aligning it with the bolt holes and securing it tightly. 3. If changing the tire on the road, prioritize safety: Park in a safe area, set up a warning sign 50-100 meters behind the car (150 meters on highways), and use hazard lights if changing the tire at night.

What does 85w90 gear oil mean?

85w-90 gear oil indicates the viscosity value of this type of gear oil. Here are some introductions about 85w90 gear oil: 1. 85w90 gear oil belongs to multi-grade viscosity all-weather type, with a wider practical temperature range and can be used all year round. 2. The W on the gear oil viscosity grade label indicates low-temperature gear oil. The number before W represents low-temperature viscosity. The smaller the number, the lower the viscosity, the better the fluidity, and the stronger the low-temperature performance. 3. The number after W represents high-temperature viscosity. The larger the number, the higher the high-temperature viscosity, and the higher the temperature resistance.

How many kilowatt-hours of electricity does a Tesla Model 3 need to charge?

Tesla Model 3 requires 60-80 kilowatt-hours of electricity to fully charge, which refers to the 85kW model. However, the actual amount may vary depending on the specific charging method. More information about Tesla Model 3 charging is as follows: 1. Tesla Model 3 charging is related to voltage, current, connection cables and plugs, chargers, and mileage. 2. There are usually several charging methods. The simplest is the standard U.S. household circuit of 120V 12A, which can directly charge the Tesla Model 3. In this case, it takes 46 hours and 17 minutes to fully charge. A high-efficiency charging station, on the other hand, can fully charge the vehicle in 4 hours and 9 minutes.

Why does the car shake when accelerating?

When the car shakes upon acceleration, the following areas should be checked: 1. The engine requires sufficient air to function properly. If there is a leak or blockage in the intake system, the car may experience shaking during acceleration. 2. In the engine ignition system, ignition high-voltage wires rarely have issues, so the main problems usually lie with the ignition coils and spark plugs, as they are wear-prone components. If the spark plugs are degraded or of poor quality, it can lead to weak acceleration and shaking. 3. The car's fuel system is extensive and consists of many components. If any part malfunctions, it can cause the engine to shake during acceleration. Examples include excessive carbon buildup in the throttle body, faulty fuel injectors, a malfunctioning fuel pump, or a clogged fuel filter.
