Should You Shift to Neutral at a Red Light in an Automatic Transmission Car?

Whether to shift to neutral at a red light in an automatic transmission car depends on different situations: 1. Shift to neutral if the red light lasts more than 30 seconds; 2. Simply press the brake if the red light lasts less than 30 seconds. An automatic transmission refers to a system where the driver does not need to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Precautions for shifting gears in an automatic transmission car: 1. Do not press the accelerator pedal when shifting gears; 2. Do not immediately press the accelerator pedal hard after shifting gears; 3. The vehicle can only be started in P or N gear; 4. To move the gear lever out of P, the brake must be pressed; 5. Do not shift into N gear while driving to coast; 6. Do not push into P gear while the vehicle is moving; 7. When changing the direction of travel, switching between D and R gears should only be done after the vehicle has come to a complete stop; 8. Placing the gear in N while driving prevents the oil pump from supplying oil normally for lubrication, which can cause the internal components of the transmission to overheat and result in damage.

Having driven automatic transmission cars for over a decade, whether to shift to neutral at red lights depends on the situation. For short stops, I just keep my foot on the brake while remaining in D gear—the soft connection between engine and transmission won't harm the car. For long red lights exceeding 60 seconds, I shift to N and engage the handbrake, giving my right foot a rest while slightly reducing transmission fluid temperature. However, frequent gear changes actually wear out the shift mechanism, so in urban areas with closely spaced traffic lights, I generally avoid shifting. Many modern cars now feature AUTOHOLD functionality which makes this even easier—a firm brake press activates auto-hold, and you can just press the accelerator to go when the light turns green.

You can query the model number on the official website of the Ministry of Ecology and Environment; 3. For registered vehicles, the emission standard can also be directly viewed from the vehicle registration certificate.

What is the vehicle scrapping period?

Non-operational vehicles and operational vehicles have different scrapping periods, as detailed below: Scrapping regulations for non-operational vehicles: For household 5-seat sedans and 7-seat SUVs, as well as non-operational small and mini cars, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping process. In addition to the above vehicles, small and mini non-operational passenger cars, large non-operational sedans, and wheeled special machinery vehicles also have no usage period limit. Common scrapping regulations for operational vehicles: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles 10 years, and large taxi passenger vehicles 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and mini operational passenger vehicles 10 years, and large and medium-sized operational passenger vehicles 15 years. Mini operational trucks have a scrapping period of 8 years, light and large operational trucks 10 years. The vehicle scrapping process is as follows: The vehicle owner applying for scrapping and renewal must fill out an "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix their seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, the vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if applicable. The vehicle owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner must submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and vehicle dismantling photos to the vehicle inspection office for verification and signature. The license plates will be reclaimed, and the scrapping registration will be processed according to regulations. Special notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if a vehicle cannot be driven back to its registration location due to damage, the owner can submit the vehicle for scrapping to a local motor vehicle recycling company. Operational vehicles converted to non-operational status must be scrapped according to the original operational vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of a motor vehicle's registration, the original owner can apply to use the original license plate number for a newly purchased vehicle when registering it. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation of registration; (2) The owner must have owned the original vehicle for more than three years.

Is Warranty Voided Without Maintenance at 4S Stores?

Maintenance outside 4S stores does not void the warranty, as warranty coverage is not exclusively tied to 4S store services. However, if the vehicle is still under warranty, it is advisable to opt for maintenance at a 4S store. The automobile three-guarantee policy stipulates that during the warranty period, consumers must have their vehicles serviced at manufacturer-authorized 4S stores to be eligible for the three-guarantee benefits. The car warranty period refers to the timeframe during which the manufacturer provides free repairs and maintenance for faults arising from quality issues. There are two conditions for warranty coverage: a time limit of 2 years and a mileage limit of 60,000 kilometers.
