How to Turn Off the Car Air Conditioning?

Turn the knob all the way to the left to turn off the air conditioning, or press the menu button below the AUTO button on the air conditioning panel. The air conditioning control interface will appear on the central control screen, and there is an OFF button in the lower left corner. Click it to turn off the air conditioning. More related information is as follows: 1. The AC in car air conditioning is the switch for the compressor. Car air conditioning includes not only the compressor but also the condenser, evaporator, expansion valve, etc. However, the compressor is one of the most important components of the refrigeration system, responsible for compressing and transporting refrigerant vapor. Therefore, turning on the AC switch is necessary for cooling, otherwise, the air conditioning system will only operate the blower, delivering air at normal temperature. In hot summer, when the AC button is turned on, adjust the temperature control to the blue position. For automatic air conditioning, set a temperature and press the AUTO button, and the system will automatically adjust the interior temperature. 2. To quickly lower the temperature inside the car in summer, adjust the position of the air vents. According to the principle of air convection, hot air rises while cold air sinks. Point the air vents slightly upward to utilize this principle. As the cold air descends, it can rapidly cool the interior. Also, avoid placing decorations in front of the air vents, as this can affect the cooling efficiency.

How to Remove the Small Round Mirror from the Rearview Mirror?

Method for removing the small round mirror from the rearview mirror: 1. First, soak the area where the small round mirror's adhesive is attached with alcohol. 2. Use a hairdryer on the hot air setting to blow on it. Don't worry about whether heating will damage the glass, as many car rearview mirrors come with a heating function. Just ensure the hairdryer isn't too close to the glass. 3. After blowing hot air for a while, the small round mirror will come off. Any remaining adhesive can be gently wiped away with alcohol, ensuring no damage to the rearview mirror. Advantages and disadvantages of the small round mirror on the rearview mirror are as follows: 1. Advantages: (1) It allows the driver to better observe the side of the car body and the rear wheels while seated in the car. If a car approaches from the blind spot, it can be detected in time. When changing lanes, a quick glance reveals the rear wheels clearly, reducing the risk of accidents. (2) For beginners reversing, having a small round mirror makes reversing easier. During parallel parking, it helps observe the relative position of the right wheel. It effectively helps novice drivers develop a sense of the car, especially during parking and reversing, enabling better awareness of road conditions. 2. Disadvantages: (1) No matter where the small round mirror is installed, it will affect the field of view of the rearview mirror. (2) When using the small round mirror, attention tends to be overly focused on it. Additionally, because the small round mirror is too small, it may lead to misjudgment of the distance of the following car, potentially causing a rear-end collision with the car in front.

Can ETC be transferred to another car?

ETC cannot be used if the vehicle information it is bound to does not match. Different types of vehicles have different highway toll fees. According to the "Rules for the Use of the Non-Stop Fast Pass System," when applying for ETC, the ETC card and OBU device are already bound to the vehicle, and the relevant vehicle information has been imported, forming a one-to-one correspondence. If you switch to a new car with a new license plate, you need to cancel the original ETC and reapply for the new car. If it's a new car with the same license plate, you can simply update the vehicle information at an offline service center. ETC is an electronic toll collection system that allows vehicles to pass through toll booths without stopping. ETC lanes are designated for vehicles equipped with ETC onboard devices, using electronic toll collection. The electronic toll collection system is an automated toll system for highways or bridges. ETC deduction principles: There will be one or more ETC lanes on highways. Through microwave dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, computer networking technology is used to conduct background settlement with the bank, achieving the goal of vehicles not needing to stop at toll booths to pay bridge and road fees. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Saves time: Eliminates the hassle of waiting in line. Green and eco-friendly: Low-carbon, as vehicles pass through toll booths without stopping, reducing noise and exhaust emissions and minimizing pollution. Reduces wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Improves efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC adoption rate among passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration into deeper integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC usage. ETC usage precautions: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of more than 10 meters to prevent the automatic sensing from charging the wrong vehicle, especially if the vehicle in front has a faulty ETC device or no ETC at all. The recognition speed for ETC lanes is 20 km/h. If the speed is too fast, the vehicle's device information cannot be read, leading to failed deductions. Unauthorized disassembly or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will cause the electronic tag to fail. It can be taken to the bank where the ETC card was issued or the highway service center for inspection. If the loosening or detachment is not due to human interference, reactivation is sufficient. When using a debit card bound to ETC, insufficient balance may also cause deduction failures. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. If the car's windshield is too thick, it may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

What Does the First Maintenance Include?

The first maintenance at a 4S shop includes the following aspects: changing the engine oil and oil filter, cleaning the air filter; checking whether the levels of various fluids are normal, inspecting the generator belt and wiper blades for any damage; checking whether the tire pressure is normal and whether there is uneven wear, bulging, or damage to the tires; inspecting the chassis, including the brake pads, brake discs, connecting rods, ball joints, CV joints, and any scratches; checking all switches in the vehicle; and ensuring the lights are functioning properly. Estimated time: Completing all tasks takes about 2 hours. Items needed for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; and the vehicle purchase invoice. Take these to the designated first maintenance facility for the vehicle. 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 undergo the first maintenance promptly, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven under standard load and normal speed as required by the vehicle. The first maintenance time is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first is the standard. The following inspections and replacements must be completed during the first maintenance of a new car: changing the engine oil, cleaning the three filters (oil filter, fuel filter, and air filter); checking whether the coolant level is normal; inspecting the vehicle's brakes and the fluid level of the clutch; checking the power steering fluid level and whether there are any leaks at the oil pipe connections; inspecting the generator, air conditioning, water pump, and belts for aging and tension; checking tire pressure and wear condition, inflating the tires, or performing tire rotation if there is wear. When changing the engine oil, the oil filter must also be replaced. The choice of oil must refer to the Vehicle User Maintenance Manual, as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, rinsing the body with water and scrubbing with a cloth. Here, it is important to note that the interior of the car body 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 cabin floor. If water enters, it will not dry but will flow through the holes to areas like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze and add the same brand of antifreeze from the beginning. Because different brands of antifreeze have vastly different chemical properties, the various functional additives in one brand may corrode those in another. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When the bolts on a moving car rust, they are often oiled to function properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricant to them, but this can pose a safety risk. When the car is driven at high speed, the bolts and nuts may loosen or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI car: The starter of an EFI car is different from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring smooth starting.

Where Can You Buy Nearly New Cars?

Nearly new cars can be purchased in the used car market. Here are some considerations when buying a nearly new car: 1. Verify documents: When purchasing, carefully check the owner's ID, original vehicle invoice, vehicle purchase tax certificate, vehicle registration certificate, annual inspection proof, and insurance policy. If the documents are incomplete, the post-purchase procedures will be very complicated. 2. Inspect the exterior: Ensure the seams between doors, front, rear, and body are smooth. If the main seams have uneven gaps, crooked lines, or missing trim pieces, it indicates the car has been in an accident and undergone repairs or major overhauls. Check for abnormal rust on seats, carpets, and other interior parts, as severe rust may indicate water damage. 3. Inspect the interior: Check if the engine operates normally without unusual noises. Examine whether oil pipes, water hoses, and wiring are aged or have leaks.
