I recently switched to a Volvo S90 and often encounter automatic start-stop issues that make driving less smooth. It's a bit annoying how the engine shuts off every time I stop. Turning it off is actually quite simple: after starting the engine, just press the button marked with an 'A' or the start-stop icon on the central console—a light press will do, and the dashboard will display that the start-stop is deactivated. Why do I prefer to turn it off? In city driving with frequent traffic lights, the constant engine stopping and starting causes more wear, especially on the battery, which ages faster. Plus, there’s sometimes a lag in acceleration, which can affect safety. Volvo designs it to be enabled by default, so I have to press the button to turn it off each time before driving, but the placement is convenient—right within easy reach. I find driving smoother with it off, with fewer worries about sudden stalls or jerks. As for fuel economy, turning it off does consume a bit more gas, but I prioritize driving comfort. The button is fixed in an easy-to-find spot on the S90, and pressing it once disables the system until the next engine start. I’d recommend trying it, especially for long drives—it’s much more hassle-free.

What is the current national subsidy for purchasing a car?

Here is relevant information about car purchase subsidies in China: 1. No subsidies for fuel vehicles: With China's vehicle ownership exceeding 20 million today, conventional fuel vehicles generally no longer qualify for government subsidies in principle, as the current major trend is developing new energy vehicles. Many countries have already announced phase-out schedules for fuel vehicles, and China is expected to gradually eliminate fuel vehicles within the next 20 years. 2. Reduction in new energy vehicle subsidies: In 2021, the subsidy standards for new energy vehicles decreased by 20% compared to 2020. Pure electric passenger vehicles with a range below 300 km receive no subsidy, while those with a range between 300-400 km (including 300 km) see reduced subsidies. Similarly, pure electric passenger vehicles with a range of 400 km or more (including 400 km) also experience subsidy reductions. To encourage the development of the new "battery swap" business model and accelerate the promotion of new energy vehicles, vehicles adopting the "battery swap mode" are exempt from these regulations.

Can National IV Emission Vehicles Be Transferred Across Provinces?

National IV emission vehicles cannot be transferred across provinces for registration and licensing in other regions; only National V emission standard motor vehicles are eligible for such applications. Below are the relevant details: 1. The implementation of the National V standard for motor vehicles is carried out regionally based on the progress of fuel quality upgrades. (1) In the 11 eastern provinces and municipalities (Beijing, Tianjin, Hebei, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, Guangdong, and Hainan), starting from April 1, 2016, all imported, sold, and registered light-duty gasoline vehicles, light-duty diesel passenger vehicles, and heavy-duty diesel vehicles (for public transport, sanitation, and postal purposes only) must comply with the National V standard requirements. (2) Nationwide, starting from January 1, 2017, all manufactured, imported, sold, and registered light-duty gasoline vehicles and heavy-duty diesel vehicles (for passenger transport, public transport, sanitation, and postal purposes) must comply with the National V standard requirements. (3) Nationwide, starting from July 1, 2017, all manufactured, imported, sold, and registered heavy-duty diesel vehicles must comply with the National V standard requirements. (4) Nationwide, starting from January 1, 2018, all manufactured, imported, sold, and registered light-duty diesel vehicles must comply with the National V standard requirements. 2. Automobile manufacturers and importers must ensure that the relevant information of their vehicles meets the standards. As the responsible entities for environmental production consistency management, they should, in accordance with the newly revised "Air Pollution Prevention and Control Law" and relevant regulations, publicly disclose the emission inspection information and pollution control technology information of their manufactured and imported vehicle models. Only after passing the inspection can the vehicles be sold, ensuring that the actual production and sales of vehicles meet the emission standard requirements. 3. The Ministry of Environmental Protection, in collaboration with relevant departments, conducts inspections of motor vehicle environmental compliance in accordance with the law. For newly manufactured and sold vehicles that do not meet the emission standard requirements, strict legal penalties will be imposed; and active cooperation will be provided to relevant departments to strengthen the management of vehicle fuels, promote fuel quality upgrades, and ensure the quality of fuel products.

Does the Three-Way Catalytic Converter Need Regular Cleaning?

The three-way catalytic converter requires regular cleaning. The use of gasoline with high sulfur and phosphorus content can form chemical deposits on the surface of the oxygen sensor and the three-way catalytic converter. Stop-and-go driving conditions may lead to incomplete fuel combustion, and the byproducts of incomplete combustion can adhere to the surface of the three-way catalytic converter. Additionally, during the cleaning of fuel injectors, throttle valves, and intake tracts, carbon deposits and particulate matter can contaminate the three-way catalytic converter. Relevant information about the three-way catalytic converter is as follows: 1. Introduction: The three-way catalytic converter is the most important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx in vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Working Principle: When high-temperature vehicle exhaust passes through the purification device, the catalyst in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting specific oxidation-reduction chemical reactions.

What to Do If You Lose Your Car Key?

Solutions for lost car keys: 1. Use the spare key: Usually, when purchasing a car, two keys are provided to prevent being unable to open the car door if one is lost. Therefore, in case of losing a key, you should quickly go home to get the spare key. Note that it's best not to keep the spare key in the car; storing it in a hidden place at home is preferable. Otherwise, losing the key can become more troublesome. 2. Contact a locksmith: If the vehicle is far from the spare key or there is no spare key, you need to find a professional locksmith to unlock the car. However, you may need to provide your ID card or vehicle registration. After unlocking, you can drive the car back to your community parking lot and then quickly get a new key made. Otherwise, you won't be able to use the vehicle normally. When going to a 4S store to get a new key, you need to bring your vehicle registration and identity information to obtain the anti-theft password and configure a new key. It's important to note that during the period of key loss, it's best not to leave valuable items in the car, as security cannot be guaranteed. Also, remember to replace the door lock to avoid unnecessary losses caused by criminals.
