What does the N in automatic transmission mean?

In automatic transmissions, N stands for Neutral. The N gear is typically used for brief stops, allowing the driver to remove their right foot from the brake pedal. However, when parked on a slope, the brake must still be applied to prevent the vehicle from rolling. Its primary function is to disconnect the power source between the engine and transmission, preventing prolonged brake pedal pressure that could raise transmission fluid temperature and potentially degrade the fluid, affecting transmission performance. Automatic transmissions feature the following gear positions: P, R, N, D, S, and L. The P (Park) gear is for extended parking, especially on inclines, as it mechanically locks the wheels to prevent vehicle movement. R (Reverse) requires pressing a safety button on some vehicles before shifting into reverse. N (Neutral) is used during vehicle startup or towing. S (Sport) mode enables free gear shifting for enhanced performance. L (Low) is for reduced speed and improved fuel efficiency in snowy conditions or heavy traffic.

Is the Light On for External or Internal Air Circulation?

When the light is on, it indicates internal air circulation; when the light is off, it indicates external air circulation. The vehicle's air conditioning system is divided into internal and external circulation modes. The internal circulation function allows air to circulate within the vehicle, cutting off the inflow of outside air. The external circulation function uses the blower to draw in outside air and blow it into the vehicle, keeping the interior air fresh. A good practice for using the car's air conditioning is to alternate between internal and external circulation. Use internal circulation more often in traffic jams, as it blocks outside air and prevents polluted air from entering the vehicle. Use external circulation more often during long drives to breathe in fresh air from outside. Internal circulation only recirculates air within the vehicle, which saves fuel and cools or heats up quickly since no outside air is involved. However, it has the disadvantage of not refreshing the interior air. External circulation draws in outside air through the blower, which helps maintain fresh air inside the vehicle but consumes more fuel and slows down cooling or heating.

How to Maintain a Used Car?

Used car maintenance methods are: 1. Replace the engine oil and three filters, which are basic maintenance items for the vehicle. Note that the engine may already have slight wear, so there's no need to choose overly high-grade oil; 2. Check the tires—tires are crucial for safety. If they reach their service life or show severe wear and aging, they must be replaced promptly; 3. Inspect all belts, especially the timing belt. It's best to replace the timing belt to ensure safety; 4. Check the braking system, including the thickness of the brake pads and whether the brake discs have obvious chamfers or cracks. If severe wear is found, replace them immediately. Also, check for leaks in the brake fluid lines; 5. Clean, disinfect, and deodorize the interior. Owners can visit a car beauty shop to eliminate lingering odors through steam sterilization, negative ion air purification, and cleaning the air conditioning ducts; 6.
