What are the lines on the rear window?

The horizontal lines on the rear window glass of a car are called defrosters, also known as demisters. Function of the car demister switch: Adjust the car demister to reduce moisture, fog, and frost on the surface of the front and rear windshields and the exterior rearview mirrors, thereby improving visibility. The symbol for the car demister switch is the front windshield with three upward-curving lines. A semicircular symbol represents the front windshield, while a rectangular symbol indicates the rear windshield. Demister button symbol: The interior demister button is located near the air conditioning control panel, and the icon on this button is easily recognizable. The icon on this button is a fan shape with many curves, representing demisting.

How long should the first charge be for a small electric car?

For the first charge of a small electric car, it should be charged for about 8 to 10 hours. Precautions for the first charge: When charging the electric vehicle for the first time, the battery should be fully charged; the first charge should be done during the day, as this makes it easier to monitor the charging time; try to fully deplete the battery before the first charge. After using the battery for 6 months: It is recommended to perform a deep discharge of the battery once a month, followed by charging the electric vehicle battery for 12 hours. This is very beneficial for restoring the battery's capacity. Generally, charging when the battery is half-depleted and before it reaches under-voltage can prevent early capacity loss and over-discharge.

Should the Handbrake Be Released When Removing a Tire?

When changing a tire, you should engage the parking gear and apply the handbrake. Tire Wrench Specifications: Generally, tire wrenches come in sizes such as 17, 19, and 21. However, it's important to refer to the vehicle's user manual for specific details. The tire wrench is part of the vehicle's onboard tools, usually stored together with other repair tools, which are typically located under the trunk's floor panel. Method for Removing a Tire: Use the vehicle's jack to lift the side where the tire needs to be changed; the lifting point is usually on the side skirt below the door. After lifting, replace the tire, install the screws, lower the vehicle, and then tighten the screws.

Is 31 kilometers normal for a new car?

A new car with 31 kilometers is normal. When a new car rolls off the production line, it undergoes numerous tests, including braking tests, power tests, drivability tests, and sealing tests, among others. Things to note when buying a car: When purchasing a car, an invoice must be issued. The name on the invoice will determine whose name appears on the purchase tax payment, vehicle registration, and the motor vehicle registration certificate. Annual insurance must also be processed by the person whose ID was used initially. Additionally, selling the car or similar transactions must be handled by the same person whose ID was used. Purchase tax: Purchase tax is a tax levied by tax authorities on certain goods and properties within the scope of the tax system, such as vehicle purchase tax. Vehicle purchase tax is a tax imposed on units and individuals who purchase specified vehicles within the country, evolving from the vehicle purchase surcharge.

Does turning on the air conditioning affect exhaust emission testing?

Turning on the air conditioning does not affect exhaust emission testing. Situation with prolonged stay in the waiting area: Normally, it is not an issue because the power for the air conditioning comes from the generator. However, if the air conditioning is left on continuously while idling in the waiting area, it may cause carbon monoxide levels to exceed the standard. This is because combustion quality deteriorates during idling, especially during prolonged idling. Exhaust emission testing: This involves analyzing and measuring the composition and concentration of exhaust gases emitted by motor vehicles during idling or under operating conditions, either on-site or using a dynamometer. The large amounts of harmful exhaust gases emitted by motor vehicles during operation are a major mobile source of environmental air pollution. Exhaust emission testing is a crucial component of environmental air pollution monitoring. The main testing items include carbon monoxide, nitrogen oxides, hydrocarbons, photochemical oxidants, and smoke density.

Is There No Impact If a New Car Is Left Unused for Several Days?

Leaving a new car unused for 7-14 days has no impact, but it is advisable to start the vehicle for 5-10 minutes every week or two to recharge the battery. Prolonged inactivity of a new car can lead to battery depletion and aging of rubber components. Battery Depletion: During extended periods of inactivity, continuous discharge from the battery can easily lead to depletion. In mild cases, it may affect the next vehicle start-up, while in severe cases, it can directly cause battery damage. Each instance of excessive discharge causes irreversible harm to the battery. Aging of Rubber Components: Rubber components in cars, such as tires and door/window seals, are highly susceptible to premature aging due to exposure to sunlight and humidity changes, leading to reduced performance and shorter lifespan. The aging of rubber components primarily occurs because rubber is an unsaturated hydrocarbon polymer, which readily absorbs oxygen from the air and oxidizes. Additionally, vulcanized rubber has a certain degree of permeability, allowing oxygen to penetrate and cause internal oxidation.
