In older Smart models, the air conditioning filter is located in a box to the upper right of the accelerator pedal. In newer Smart models, the air conditioning filter is positioned beneath the passenger-side floor mat. Below are the functions of the car's air conditioning filter: 1. It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the car's interior. 2. The activated carbon and other materials inside can adsorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., providing strong and long-lasting moisture absorption. 3. It separates solid impurities such as dust, pollen, and abrasive particles from the air. 4. It maintains clean air inside the car, preventing bacterial growth and creating a healthy and comfortable riding environment. It effectively blocks dust, pollen, and abrasive particles, ensuring drivers and passengers do not experience allergic reactions that could affect driving safety. 5. The filter removes moisture, preventing the car's windows from fogging up easily, thus improving visibility and driving safety. It supplies fresh air to the cabin, protecting occupants from harmful gases and enhancing driving safety, while also offering strong antibacterial and deodorizing effects.

As a seasoned driver who has owned a Mercedes-Benz Smart for several years, I find the location of the cabin air filter quite confusing. It's hidden behind the glove compartment in front of the passenger seat, and you'll need to remove the storage compartment first to access it. Most models secure it with plastic clips—just gently pry them open with a small flathead screwdriver without applying too much force to avoid damage. I've replaced it several times myself; while the location is fixed, the space is tight, so patience is key during the process. Remember, the filter is crucial for trapping dust and pollen, so replacing it every six months or 10,000 kilometers prevents odor buildup. I usually opt for activated carbon filters, which I find highly effective at eliminating odors, making long drives much more comfortable. Neglecting regular changes can lead to clogging, reducing AC efficiency or even causing mold growth, which impacts health. Overall, DIY replacement saves money, and once you locate it, the rest is straightforward.

What are the required procedures and documents for second-hand car transfer in Dongguan?

Dongguan vehicle transfer requires the following materials: vehicle license, motor vehicle registration certificate, motor vehicle registration supplementary form (obtained from the local vehicle management office in the vehicle's jurisdiction area with ID card and vehicle license), vehicle purchase tax certificate, ID cards and household registration books of both buyer and seller. For non-local residents, a temporary residence permit is required, and the buyer's temporary residence permit must be valid for at least one year. 1. Second-hand vehicle market: The transfer process is handled by operating companies, and the transfer window does not directly serve consumers. Drive the car to the market, and an old motor vehicle operating company will complete the transfer procedures on your behalf: evaluation, vehicle inspection, and ticket issuance. 2. Contract signing required: Both buyer and seller need to sign the "Second-hand Motor Vehicle Sales Contract" supervised by the industrial and commercial department. The contract is in triplicate, with one copy for each party and one retained by the industrial and commercial department. The vehicle transfer or relocation procedures can only be processed after filing with the industrial and commercial department.

How to Fix No Airflow from the Passenger Side Air Conditioner?

No airflow from the passenger side air conditioner is usually caused by issues with the cabin air filter or the blower motor. Below are detailed descriptions of the problems: Cabin Air Filter Clogged: If the cabin air filter is clogged, the airflow will be restricted, resulting in no air coming out of the air conditioner. Therefore, if you notice that your car's air conditioner is not blowing air or the airflow has weakened, the first step is to check if the cabin air filter is dirty. Typically, after cleaning or replacing the filter, the airflow will return to normal. During inspection, you can remove the filter to see if the airflow increases. If it does, the filter is clogged; if there's no change, the issue lies elsewhere. Blower Motor Malfunction: The blower motor is a crucial component of the air conditioning system, responsible for circulating air inside the vehicle. When using the air conditioner at higher fan speeds, you may often hear a humming sound coming from under the passenger seat. This is the sound of the blower motor working—the higher the airflow demand, the faster the motor operates to draw in air. If the blower motor is damaged, it may fail to draw sufficient air or stop working altogether, preventing airflow from the air conditioner. To diagnose, set the fan speed to maximum and listen for the blower motor's sound. If it doesn't spin or spins too slowly, it indicates a malfunction, and the owner should visit a 4S shop or repair facility for servicing.
