The FOLDER button on the car radio refers to the folder function, allowing you to switch between folders. Below are specific introductions to common car buttons: 1. A-OFF. This button turns off the engine auto start-stop feature. It is used in congested or waterlogged areas to ensure normal engine output. 2. AUTO-HOLD. The auto-hold button, usually located next to the electronic handbrake, temporarily shuts off the engine during traffic lights or temporary stops. 3. DUAL. The DUAL button controls dual-zone air conditioning. When the indicator light is on, you can set different temperatures for the driver and front passenger seats. After adjusting to the desired temperature and turning it off, the automatic air conditioning will regulate the temperature according to the set values.

Throughout my driving career, I've encountered heavy fog many times. The 'folder' on cars—I guess you might mean fog lights—are real lifesavers in foggy conditions! Unlike regular headlights, they're positioned low on the front bumper, close to the ground. Their light cuts through fog to illuminate the road instead of reflecting back, giving drivers much better visibility in bad weather. I often drive in rainy, foggy areas, and activating the fog lights immediately makes me feel safer with noticeably clearer vision. The key is not to misuse them—only turn them on when visibility drops below 100 meters, otherwise the intense light can dazzle other drivers. Some cars even come with yellow fog lights, which have even stronger penetration—quite a practical little feature.

How to reset the tire pressure on a 2020 Odyssey?

2020 Odyssey tire pressure reset method: First, turn on the ignition, press and hold the tire pressure monitoring reset button until you hear a "beep," then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the dashboard warning light will turn off, completing the tire pressure reset. Precautions for inflating tires: Always use a pressure gauge to check the pressure to avoid overinflation, which can cause the tire to burst. After stopping, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting pressure. Check the valve stem. If the valve stem and core are not properly aligned, have protrusions, depressions, or other defects, it will be difficult to inflate and measure pressure. Pay attention to cleanliness when inflating. The air pumped in should not contain moisture or oil to prevent damage to the inner tube rubber. Do not exceed the standard pressure too much and then deflate, nor overinflate due to prolonged inability to inflate while traveling. Exceeding the standard pressure excessively can overstretch the cords, reducing their strength and affecting the tire's lifespan.

What is the reason for the failure of auto start-stop after replacing the battery?

The reason for the failure of auto start-stop after replacing the battery is: The battery replaced is not a dedicated start-stop battery. Starting the engine (start-stop function) requires a large current, and ordinary car batteries do not have good cyclic charging capability. Installing a regular battery will definitely prevent the start-stop function from working. Steps to replace the start-stop battery: 1. Open the two fastening buttons of the heat insulation cotton, lift the red and black insulating covers above the positive and negative terminals, and then locate the tightening nut of the battery negative terminal; 2. Use a wrench to loosen the tightening nut of the negative terminal, then use a flat-head screwdriver to slowly pry open the fastening block, and directly pull out the negative terminal; 3. Remove the positive terminal; 4. Unscrew the nut used to fix the battery locking strap and loosen the locking strap, then you can directly take out the car battery.
