The "A-OFF" button in a car is the auto start-stop switch, used to control the engine's automatic start-stop function. Below is a related introduction to auto start-stop: 1. Function: When the auto start-stop function is enabled, simply press the brake pedal while driving, and the engine will automatically shut off after the vehicle comes to a complete stop for a few seconds. Releasing the brake or turning the steering wheel will automatically restart the engine. 2. Purpose: The core of auto start-stop is to automatically control engine shutdown and restart, allowing the vehicle to temporarily turn off the engine during brief stops. After shutdown, the power supply replaces the belt pulley to provide operation power for the engine cooling fan and in-car air conditioning, aiming to save fuel, reduce emissions, and decrease exhaust output.

How to Clean Car Seat Belts?

Cleaning tips for seat belts: 1. For stains on car interior items, foam cleaner is practically a universal solution. Spray the cleaner onto the seat belt, wait for a dozen seconds, then gently scrub with a soft brush. After cleaning, wipe it dry with a clean towel. Note: Do not use the seat belt before it is completely dry. 2. If foam cleaner is not available, soapy water can also be used for cleaning. Avoid using highly corrosive cleaning products. Fully extend the seat belt and secure the top with a binder clip, then soak the belt in warm soapy water. After cleaning, dry it with a soft cloth. 3. Before the seat belt is completely dry, do not remove the binder clip at the top. Wait until it is fully dry before retracting it. If the seat belt fails to tighten promptly after cleaning, it is advisable to have it inspected at a professional repair shop.

Currently, there are models such as Santana, Santana 2000, and Santana 3000. 2. It is produced by Volkswagen AG in California, USA. Here are some extended guidelines on the usage of car engines: 1.

How to Check the Manufacturing Year of a Car from the Glass?

There is a code on the lower left or lower right corner of the car window glass. On the last or second-to-last row, there is a number and several small black dots. The number represents the production year of the glass, indicating the last digit of the year, while the small black dots indicate the production month. Below is a detailed explanation: 1. The production date of the car glass can be identified by the code on the lower left or lower right corner of the window glass, where the last or second-to-last row contains a number and several small black dots. 2. First, the number represents the production year of the glass, indicating the last digit of the year, while the small black dots indicate the production month. 3. If you observe the glass carefully, you will notice that some glasses have the small black dots in front of the number, while others have them behind the number. 4. If the small black dots are in front of the number, subtract the number of dots from 7; if they are behind the number, subtract the number of dots from 13. The result is the production month of the glass. 5. Some glasses may also have a few larger black dots after the production year and month. These dots specify the week of the month, for example, 5 dots represent the first week; 4 dots represent the second week; 3 dots represent the third week, and so on.
