2021 Tiguan L air conditioning usage instructions are as follows: 1. Defogging: The defogging buttons include front windshield and rear windshield. Press the corresponding button to activate the windshield defogging function. 2. Heating: Rotate the knob to the high-temperature indicator area to deliver warm air. When using heating, please turn off the A/C switch. Because the air conditioning cooling switch only activates the compressor during cooling, while heating is provided by coolant temperature and fiberglass heat. 3. AUTO: Press the AUTO button, and the air conditioning system will automatically maintain stable cabin temperature without manual settings. Whether cooling or heating, or adjusting airflow higher or lower, it intelligently makes timely adjustments. 4. Internal/External Circulation: Internal circulation means closed-loop air circulation inside the cabin, while external circulation exchanges air between inside and outside the vehicle. Use internal circulation in congested areas or poor air quality environments. When using internal circulation for extended periods, it should not exceed one hour before switching to external circulation to prevent air quality from affecting health (except in extremely poor external environments). 5. Temperature Zone Synchronization: With the temperature zone synchronization function, changing the driver's side temperature will synchronize changes in other zones. After disabling this function, each zone can be set individually to meet the needs of passengers in different positions.

After starting the car, I usually press the AUTO button on the center console right away. It automatically adjusts the fan speed and cooling intensity based on the set temperature. If I want to adjust the temperature, I just turn the round temperature knob—both the driver and passenger sides can be set to different temperatures independently. On particularly hot days, I press the MAX AC button to maximize the cooling power for a quick cooldown. In winter, there’s no need to turn on the AC button; setting the temperature to around 20 degrees after the engine warms up feels very comfortable. Adjusting the airflow direction is easy via the touchscreen, and the defogger button is a must-have for rainy days. Regularly replacing the cabin air filter is also important—I change mine every six months to maintain cooling efficiency and prevent odors. The rear vents can also be individually controlled, and my family says it makes riding much more comfortable.

How to Revive a Car Battery That Has Been Sitting for a Long Time?

How to revive a car battery that has been sitting for a long time mainly depends on whether the battery can still be charged. If it can still be charged normally, simply follow the standard charging procedure to fully charge the battery, and it should return to normal. If the battery cannot be charged, you can use the activation mode of a smart charger to revive the battery before charging it. A car battery, also known as a storage battery, is a type of battery that converts chemical energy into electrical energy. The commonly referred-to car battery is a lead-acid battery, which primarily uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Tips for maintaining a car battery: 1. Clean the battery regularly; 2. Reduce electrical usage when the engine is off; 3. Replace the battery periodically; 4. Start the car regularly.

Do Car Decals Need to Be Registered?

Decals on the exterior of a car generally do not require registration, but large-scale body advertisements do. Car decals, an earlier colloquial term now referred to as car stickers, originated from motorsports. Precautions for Car Decals: The ideal working environment for applying decals is between 15°C and 30°C. High temperatures can cause the film to expand and the wet solution to evaporate quickly, while low temperatures can affect the flexibility of the film, thereby impacting adhesion. Thoroughly clean the car's surface with water and a neutral cleaner. To ensure proper application of the decal, the car's surface must be free of dust, wax, and other contaminants. Car decals consist of three layers: the backing paper (white glassine paper), the PVC decal itself, and the transfer film with protective film (transparent). The top protective film should be removed only after the final application. During the process, avoid pulling the decal forcefully to prevent stretching and deformation. Points to Note for Vehicle Modifications: First, technical parameters such as the car's displacement must never be modified privately. For example, some people exploit loopholes by purchasing new cars with smaller displacements that have lower purchase taxes and then privately upgrade the displacement significantly. This is not only a serious legal violation but also poses significant safety hazards. Second, widening tires, modifying the intake system, or exhaust system is also prohibited. These modifications can alter the vehicle's performance and severely affect driving safety. If discovered, fines will be imposed, and the vehicle must be restored to its original condition. Third, for non-professional off-road competition vehicles, modifications that enhance off-road performance, such as raising the chassis, are not allowed.

What are the requirements for installing a charging pile?

Automobile charging pile installation requirements include: consent from the residential property management and having a fixed parking space within the community. Steps for installing an automobile charging pile: Step 1: Apply for confirmation from the property management. Understand the community's charging pile installation policy, inspect the installation environment, and if additional technical equipment is required, apply to the community in advance. Generally, a fixed parking space is needed. Step 2: Determine the location of the parking space. Most communities have a power distribution room, and the distance between the parking space and the distribution room becomes a decisive factor in cost control—the closer the distance, the lower the cost. Step 3: Prepare materials and apply to the power company. Required materials include: a copy of the ID card, proof of parking space ownership, and an installation agreement signed by the property owner. Step 4: Inspection and installation. After receiving the application, the power company will conduct an on-site inspection, requiring the presence of the property engineer, charging pile company, power company, and the owner to finalize the construction plan. Depending on the distance between the parking space and the distribution room, the construction time varies, ranging from a few hours to a day. Step 5: Acceptance. After completion, the charging pile company needs to report to the power company. Upon passing the power company's inspection, they will stamp the approval and issue the corresponding electricity card.

How Often Should a Sedan Be Topped Up with Water?

How often a sedan needs to be topped up with water depends on the scale of the car's radiator. When the coolant level in the radiator falls below the MIN mark, it indicates that water needs to be added. It's important to note that the water added here refers to antifreeze, not tap water. The full name of antifreeze should be called antifreeze coolant, which refers to a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers multiple functions, including preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.
