Different car models have different locations for the recirculation switch. Taking the Volkswagen Tiguan as an example, its air recirculation button is a small car-shaped key on the center console. Normally, it is recommended to keep the air circulation on the external mode to allow better airflow between the inside and outside of the car. However, in summer, to cool the car faster, first turn on the recirculation mode, then switch to external circulation. Below are relevant details about internal and external circulation: 1. Use of external circulation: Generally, if the outside temperature is too high and you want to quickly lower the temperature inside the car, you should turn on the external circulation to rapidly expel the hot air from the car and reduce the burden on the air conditioning. Also, if there are smokers in the car, turning on the external circulation can quickly remove harmful gases from the car, ensuring the safety of the passengers. For newly purchased cars, it is advisable to frequently use the external circulation to expel harmful substances like formaldehyde as quickly as possible. 2. Use of internal circulation: During traffic jams, it is essential to switch to internal circulation to effectively prevent harmful exhaust gases from entering the car. For short-distance driving, it is also recommended to use internal circulation to further reduce the car's fuel consumption. However, for long-distance driving, frequent use of external circulation is necessary to maintain fresh air inside the car and prevent accidents caused by driver fatigue due to lack of oxygen.

How to reset the maintenance light on a 2019 Great Wall Pao with one-button start?

Press the mode switch button and the left time adjustment button on the instrument panel simultaneously. There are 3 maintenance taboos to note: 1. Avoid unventilated spaces: Do not run the engine for extended periods in unventilated garages. Engine exhaust contains carbon monoxide, and prolonged exposure to low concentrations can cause headaches, rapid breathing, nausea, vomiting, weakness, dizziness, mental confusion, and even brain damage. 2. Never siphon fuel with your mouth: Gasoline is not only flammable and explosive but also toxic, especially leaded gasoline, which harms the nervous system, digestive tract, and kidneys. Additionally, gasoline contains high concentrations of sulfides, and hydrogen sulfide is poisonous. Ingesting gasoline can lead to poisoning or death. 3. Avoid contact with carburetor cleaner: Most carburetor cleaners contain methyl chloride, aromatic compounds, and ethanol. Inhaling these substances or getting them on skin and eyes poses safety risks.

Should T-equipped cars use 30 or 40 oil?

It depends on individual circumstances. Choose 40 for mineral oil, and 30 for synthetic or full synthetic oil. Here are the relevant details: Introduction: Cars with "T" refer to turbocharged engines. It is best to choose oil with slightly higher viscosity, such as 5W30, 0W40, or 5W40 engine oil. In addition to using the manufacturer's specified oil, full synthetic and semi-synthetic oils are also good choices. Turbocharging: The structure of turbocharging places higher demands on the engine, as its internal components must withstand high temperatures and greater impacts, compression, and other working conditions. When selecting oil for turbocharged cars, it must have excellent anti-wear properties and be heat-resistant. Full synthetic or semi-synthetic oils can precisely meet these requirements. The turbocharger is one of the most vulnerable components in a turbocharged engine. According to relevant data, over 80% of turbocharger failures are due to insufficient lubrication from the oil. Full synthetic oil is currently the most suitable choice for turbocharged engines.

What are the methods to remove film without damaging the heating wires?

The following are methods to remove film without damaging the heating wires: 1. Use a hard card: Use your fingernail or a hard card like a bank card to lift one corner of the car film. If that doesn't work, use a utility knife. 2. Avoid violent operation: Do not operate roughly during the process; simply spray water to moisten it beforehand. Additional information: The functions of car film are as follows: 1. Prevent glass from shattering: Generally, car film adds a layer of strong and flexible protection to the glass, so even if the glass breaks due to an accident, the film will still provide protection. This prevents glass fragments from flying around, adding an extra layer of safety. 2. Ensure safety: It not only enhances the safety of the car but also protects personal safety. However, the quality of car films on the market varies, so it's important to recognize quality and purchase carefully. When selecting a car film, be sure to invest in the windshield film.

Will refueling after the nozzle automatically stops have any impact on the car?

Refueling after the nozzle automatically stops will not have a significant impact on the car. After the nozzle stops, wait a few seconds to allow the fuel vapor in the tank to slowly escape, slightly reducing the pressure. At this point, you can add a little more fuel to the tank. The reasons for the nozzle stopping during refueling and precautions are as follows: Reasons for the nozzle stopping during refueling: Vapor generation during refueling: When refueling, if the fuel flows too quickly from the nozzle, it can generate expanding vapor that doesn't have time to escape. If the carbon canister solenoid valve is closed at this time, the carbon canister will accumulate more and more gas, leading to fuel splashing, even though the car's fuel tank is not yet full. Precautions during refueling: Insert the nozzle as deeply as possible into the tank opening to prevent fuel from splashing out when the nozzle stops.
