Can a dash cam record when the car is not started?

It depends on whether the installed dash cam has a parking monitoring mode. If it does not have this mode, it cannot record after the car is turned off. Even dash cams with a parking monitoring mode will only start recording when necessary. Power supply for dash cams with parking monitoring function: Dash cams with parking monitoring function abandon the traditional method of drawing power from the cigarette lighter or USB port, and instead use a step-down cable to directly draw power from the ACC fuse box. Usage of dash cams with parking monitoring function: After the vehicle is parked and turned off, the dash cam will automatically shut down and enter a low-power sleep mode. However, once it detects a collision or movement of objects in front, it will immediately wake up and record the surrounding images.

Can I renew my expired driver's license in another city?

Driver's licenses can be renewed in another city before expiration, but not after. Relevant regulations: According to the driver's license usage regulations, an expired driver's license cannot be directly renewed in another city. However, you can first transfer it to your place of residence and then proceed with the renewal. For out-of-city renewal, it must be done before the license expires. After expiration, you must return to the vehicle management office in the issuing city to apply for renewal. Time limit for out-of-city renewal: Out-of-city renewal should be applied for at the vehicle management office within 90 days before the license expires. If you fail to renew within the specified time, you can still proceed with the renewal within one year after expiration.

Why does the tire pressure rise from 180 to 190 after driving for a few minutes in winter?

The reason why the tire pressure rises from 180 to 190 after driving for a few minutes in winter: the tire is overinflated, and prolonged operation generates heat through friction, leading to increased tire pressure. Below are the specific reasons: Friction generates heat: When the car is in motion, the tires are the main friction components. As the car moves, the continuous friction between the tires and the road surface causes the tire temperature to rise, naturally increasing the tire pressure. Solutions for excessive tire pressure: If the vehicle's tire pressure is too high, it is advisable to release some air to bring the tire pressure back to the normal range. Otherwise, it will not only affect the driving experience but also pose certain risks. Driving with excessively high tire pressure will make the tires feel less elastic, leading to abnormal wear and reducing the tire's lifespan. Moreover, under high-speed and high-temperature conditions, it increases the risk of tire blowouts.

What does PEA in fuel additive mean?

PEA in fuel additive refers to the component added to the fuel additive: Polyether Amine (PEA). Performance of PEA additive: From practical usage effects, fuel additives containing Polyether Amine (PEA) indeed have good carbon deposit removal capabilities. However, claims about fuel savings and power enhancement are more psychological, as these effects are hardly noticeable in actual usage. Usage of PEA additive: This type of cleaning fuel additive is for periodic use. It is generally sufficient to add it once every few thousand kilometers. Continuous use is not recommended, as it may cause engine shaking, increased fuel consumption, and other issues.

Should the A/C Be Turned On in Winter for Car Air Conditioning?

In winter, turning on the air conditioning is for heating, and there is no need to turn on the A/C. Below are the specific reasons and the principle of how the air conditioning provides warm air: Reasons not to turn on the A/C: The A/C light indicates that the air conditioning compressor is activated, which increases the engine load and fuel consumption. The warm air in a car's air conditioning system is provided by the engine coolant, so there is no need to turn on the A/C when using the heater in winter. Principle of how the air conditioning provides warm air: The warm air from the air conditioning is supplied by the engine coolant, which is the "water" in the radiator. Two hoses are connected from the engine coolant circulation loop to the heater core inside the air conditioning assembly. The warm air is delivered into the cabin by the fan, which transfers the heat from the heater core. Using the air conditioning for heating in winter neither affects the vehicle's power nor increases fuel consumption.

Do Cars Need to Change to Antifreeze Engine Oil in Winter?

Cars need to change to antifreeze engine oil in winter. Antifreeze engine oil has lower viscosity, which can protect the engine during winter. Engine oil that has been used for a long time, turned black, or has reduced adhesion should be replaced to ensure smooth engine startup. Below are the methods and precautions for changing engine oil: Methods for Changing Engine Oil: Loosen the nut at the bottom of the transmission oil pan to allow the old transmission oil to flow out naturally by gravity; connect the transmission and the circulation machine through pipeline interfaces, and the pressure-type transmission oil will push out the old transmission oil; remove the oil pan for oil change. Precautions for Changing Engine Oil: When changing the engine oil, it is best to replace the oil filter as well, otherwise accumulated impurities can easily cause blockages; the oil pan bolt should be replaced each time the oil is changed; try to choose multi-grade oil, as it is economical, has a long service life, and provides good protection for the engine.
