How to Use the Car's Air Recirculation?

The method to use the car's air recirculation is: press the air recirculation button inside the car. In recirculation mode, the air exchange channel between the inside and outside of the car is closed. When the fan is off, the air inside the car does not circulate. When the fan is on, the air drawn in comes from inside the car, forming an internal air circulation. The purpose of the car's air recirculation is to block out polluted air, prevent external gases from entering the car, and ensure clean air inside the vehicle. The functional buttons in the car include: 1. Headlight washer button: used to control the automatic headlight cleaning function; 2. Parking sensor button: press this button to manually control the parking sensors; 3. Central locking button: the control button for the car's central door locks.

What Documents Are Required for a Car's First Maintenance?

Items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle's purchase invoice. Take these to the designated first maintenance service provider for the vehicle's initial service. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after the new car has been driven. The specific time varies by vehicle, generally after driving 1,000 to 3,000 kilometers. The car must attend the first maintenance on time, neither earlier nor later. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard loads and normal speeds as required by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. First maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Estimated time required: Approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced. The selection of engine oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car should not be directly rinsed with water. If the floor mats are dirty, use a vacuum cleaner or take them out, scrub them with a brush and detergent, dry them, and then put them back. There are many drainage holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry but will flow through these holes to areas like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it is recommended to drain the existing antifreeze and add the same brand from the beginning. Since antifreeze brands differ, their chemical properties vary significantly. Different types of corrosion inhibitors can corrode each other. Different brands of antifreeze use different corrosion inhibitors, so they should not be mixed to avoid unnecessary issues. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function again. Some people apply lubricant to the bolts and nuts to prevent rust, but this poses a safety risk. At high speeds, the bolts and nuts can loosen or even fall out, leading to driving malfunctions. Do not press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car is different from that of a conventional car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

How to Deal with Foggy Car Windows on Rainy Autumn Days?

Press the defogging button, turn on the air conditioning cooling (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. Both cold and warm air can be used to defog car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days as it will initially worsen the fog. When the car windows fog up, the external circulation should be turned on. The reasons for car windows fogging up: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface of the cooler side will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on in time, the high humidity of exhaled air can quickly cause the windshield to fog up. At this time, turn on the air conditioning to blow cold air onto the windshield, using the dehumidification function to remove the fog quickly. If the humidity is too high and the air conditioning is not effective enough, slightly open the window to quickly reduce the humidity inside the cabin. Of course, combining this with the air conditioning will yield faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the windshield, reducing the temperature difference between the inside and outside surfaces of the window, thereby preventing excessive fogging. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. The temperature control should not be set to the coldest position, as this can cause the outer surface of the windshield to fog up over time. Applying Anti-Fog Spray for Prevention: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed, effectively preventing water vapor from condensing on the glass and forming fog, which is especially useful in cold winters. Alternatives to defogging agents include dish soap, soapy water, glycerin, alcohol, or saltwater. After applying, let it dry and then wipe off any excess with a chamois or soft dry cloth. This can keep the car windows fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not too heavy, opening the side windows can create airflow between the inside and outside of the car, reducing the temperature difference and gradually eliminating the fog. The principle of this method is the same as using cold air from the air conditioning. However, the drawbacks of opening windows for airflow are obvious—it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars have a rear windshield electric heating function, although the button locations may vary, the function is the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.

Where is the appropriate place to install the ETC device?

The installation position for ETC in small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the middle to lower part. The suitable installation position should be at a height of no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC device should be installed in the microwave skylight zone. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is made by someone other than the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag requires power but generally does not need to be charged or have its battery replaced, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the anti-tamper lever in. If the device is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll deduction for the wrong vehicle. The speed limit for ETC lane recognition is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and cause toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.
