Automatic air conditioning activation is a comfort feature in BMW vehicles. It is designed to automatically activate the air circulation system or the air conditioning system to adjust the cabin temperature when the driver enters the vehicle after it has been parked for an extended period. BMW refers to this as the parking ventilation system or stationary ventilation system. Parking Ventilation System: The parking ventilation system is used to ventilate the interior space and, if necessary, reduce the cabin temperature. The system can be directly turned on and off via two preselected activation times. It can remain active for up to 30 minutes. Through iDrive, the "Parking Ventilation System" can be operated to open the ventilation outlets at preselected activation times or during direct operation, allowing air to flow out at any external temperature. Function of Car Air Conditioning: The air conditioning system can control the temperature inside the cabin, both heating and cooling the air to maintain a comfortable level of cabin temperature.

Where to Add Windshield Washer Fluid in a Corolla?

Open the engine hood, and you will find a windshield washer fluid reservoir on the front-right side of the engine compartment. The cap of the reservoir typically features a windshield wiper symbol and is usually blue in color. This is where you add the windshield washer fluid. Below is some related information about windshield washer fluid: 1. Windshield washer fluid, commonly known as car windshield cleaning fluid, is a type of automotive consumable. It is primarily composed of water, alcohol, ethanol, corrosion inhibitors, and various surfactants. While driving, if you notice reduced transparency of the windshield, using windshield washer fluid will restore a clear view. 2. If the windshield washer fluid runs out, it is essential to replenish it promptly. Note that tap water should not be used as a substitute for windshield washer fluid, as it lacks the cleaning efficacy of the latter. Since windshield washer fluid is a consumable item, it is advisable to regularly check its level and top it up as needed.

What kind of engine oil does the Kuga use?

The factory-recommended oil for the Kuga is fully synthetic Mobil 5W-30 engine oil. The 5W-30 viscosity grade has strong adaptability across most regions in China, though areas with extremely cold temperatures like Northeast China might require oil with better fluidity. Since turbochargers operate at high speeds and rely on oil lubrication, all turbocharged engines demand higher-quality engine oil. Below is some relevant information about engine oil: 1. 5W30 refers to the SAE standard viscosity rating, indicating this is a multi-grade oil. 2. The "W" stands for WINTER, and the number before W represents the oil's flow performance at low temperatures - the smaller the number, the better the cold-start performance. The number after W indicates the oil's stability at high temperatures - the larger the number, the better the high-temperature stability. 3. The smaller the number before W, the lower the oil's viscosity at low temperatures, resulting in better low-temperature fluidity and suitability for colder climates.
