You need to go to a 4S shop for computer detection, and generally, an upgrade can solve the problem. Here is the relevant introduction: 1. Rear radar sensor: The left rear and right rear bumper radar sensors are located on the rear bumper, and their function is to monitor objects (obstacles or vehicles) in areas that cannot be observed by the outside rearview mirrors. The monitoring distance is S=0.18∼30m, the resolution is S=0.04m, the detection angle is 80°, and the tracking detection angle is 130°. 2. Front radar sensor: The left front, right front radar sensors and the front long-range radar sensor are located on the front bumper, and their function is to monitor the environment in the front area of the vehicle. The maximum detection distance is 30m, and the maximum angle is 130°. 3. Blind Spot Assist System warning light: The left and right Blind Spot Assist System warning lights (M21/1e2 and M21/2e2) are located on the left and right outside rearview mirrors, respectively, and are actuated by the left front and right front door control units. After actuation, they appear red, aiming to warn the driver.

Is There a Big Difference Between BMW 3 Series and 5 Series?

There are significant differences between the BMW 3 Series and 5 Series, mainly in the following aspects: 1. Exterior: The wheelbase of the BMW 5 Series is noticeably longer than that of the 3 Series. The distance from the front axle to the rear axle is the wheelbase, and a longer wheelbase means more spacious seating and greater operational stability. 2. Interior: The overall craftsmanship and materials used in the BMW 5 Series interior are more premium compared to the 3 Series. 3. Power: The 3 Series is equipped with a B48 engine, with the 325 model delivering a maximum power of 135 kW and a peak torque of 300 N·m; the BMW 5 Series 525 model also uses a B48 engine, with a maximum power of 135 kW and a peak torque of 290 N·m.

Does a car registered in July 2013 require an annual inspection in 2021?

According to the new annual inspection regulations, for vehicles registered in 2013, if the inspection was conducted before November 20, 2020 (when the new policy took effect), an inspection is required in 2021; if the inspection was conducted after November 20, 2020, no inspection is required in 2021. Relevant details are as follows: 1. New regulations: Under the new inspection rules, non-operational small passenger vehicles (excluding minibuses) aged between 7 and 9 years are exempt. For non-operational small passenger vehicles (excluding minibuses) older than 6 years but less than 10 years, the annual inspection frequency is adjusted to once every two years. 2. Inspection: For private cars older than 10 years, the inspection cycle remains unchanged as per the original regulations, i.e., once a year for vehicles aged 10 to 15 years, and once every six months for vehicles older than 15 years.

What Does the Snow Mode in Cars Mean?

Snow mode is a switch near the gear lever, marked with a snowflake symbol. When activated during snowy conditions, it helps the car start smoothly on icy or snowy roads. The principle behind it involves computer-controlled transmission adjustments, allowing the vehicle to start in second or third gear for more stable traction, reducing torque output, and minimizing tire slippage on slippery surfaces. Here are some driving tips for icy and snowy roads: 1. Prevent Slipping During Start: When driving on icy or snowy roads, tires are prone to slipping. Sometimes, the harder you press the accelerator, the worse the slipping becomes. To start smoothly, maintain steady control of the accelerator. 2. Check Wipers Before Departure: Before driving, ensure the wipers and windshield washer fluid are functioning properly. Make sure the wipers aren't frozen. During the drive, snow on the roof may melt and flow onto the windshield, requiring the use of wipers. If the snow is dirty, windshield washer fluid may be needed for cleaning, so ensure both are operational. 3. Avoid Sudden Acceleration Slipping: When driving on icy or snowy roads, avoid slamming the accelerator. Doing so may cause wheel slippage, reducing acceleration efficiency. For two-wheel-drive vehicles, this can compromise driving safety. 4. Slow Down in Corners: Entering a turn at high speed can lead to understeer, causing the front of the car to slide outward and lose control. Before entering a turn, release the accelerator pedal slightly and steer gently. Avoid sharp turns, as aggressive steering can cause oversteer, especially noticeable in rear-wheel-drive vehicles.

How to Identify Whether a New Car Meets China 5 or China 6 Emission Standards?

The methods to identify China 5 and China 6 emission standards are as follows: 1. The most crucial difference lies in the emission standards, with China 6 being significantly stricter than China 5. According to the '2017 Air Pollution Prevention and Control Work Plan' issued by the Ministry of Environmental Protection, China 6 standards impose a 40% stricter limit on carbon monoxide, PM fine particulate matter, and benzene content in gasoline compared to China 5. 2. Compared to China 5, China 6 has enhanced the testing requirements for hybrid vehicles, including regulations on energy storage systems, thermal management systems, drive motors, generators, and plug-in EES. 3. With the introduction of China 6 emission standards, China 5 vehicles have experienced a significant depreciation in value, China 3 vehicles are directly scrapped, and China 4 vehicles face driving restrictions. In contrast to when China 5 standards were first introduced, the requirements for China 3 and China 4 vehicles were not as stringent.

What does the dual credit policy for automobiles mean?

Dual credits refer to the Corporate Average Fuel Consumption (CAFC) credit and the New Energy Vehicle (NEV) credit for passenger vehicle manufacturers, with both credits being calculated based on the performance of passenger vehicle manufacturers. Below are the specific details about fuel consumption credits: 1. Calculation formula: Fuel consumption credit = (Standard value - Actual value) * Actual production volume. If a manufacturer meets the standard, it will generate positive fuel consumption credits; if not, it will generate negative fuel consumption credits. 2. Based on driving range: The actual value and target value of NEV credits are calculated according to the per-vehicle credits based on driving range, the NEV credit ratio requirement for manufacturers, and the production and import volume of NEVs. If the actual value exceeds the target value, it results in positive NEV credits; otherwise, it results in negative NEV credits.
