What is the wading depth of the BMW 5 Series?

The BMW 5 Series is a sedan with a wading depth of 25cm. Generally, the safe wading depth for most vehicles should not exceed half the height of the tires, and the absolute limit is not to exceed the engine air intake. If the air intake is below the water level during wading, water can be sucked into the engine cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshaft, etc.). Here are some precautions after driving through water: Orderly passage through flooded areas: If there are multiple vehicles, it's best to pass through the flooded area one by one. When several cars go through water together, the waves created by the leading vehicle can affect the passage of following cars. During wading, avoid shifting gears or accelerating/decelerating in the water. If the engine stalls in the water, do not attempt to restart the vehicle. Disable auto start-stop when wading: Most BMW models are equipped with an auto start-stop system. If driving through water, the vehicle may automatically shut off when braking. After the engine stops, water could enter the engine through the exhaust pipe. Releasing the brake would cause the vehicle to restart automatically, potentially leading to engine damage.

Can ECO Mode Be Used Frequently?

You can frequently use the ECO mode in your car. ECO mode, also known as economy mode, is particularly effective for fuel savings when driving in congested urban traffic. Under ECO mode, engine carbon buildup is roughly the same as in normal driving mode, so ECO mode can be left on continuously. The main principle of ECO mode is not complicated. It involves comprehensive judgment and analysis of factors affecting fuel consumption during driving, such as automatic transmission gear, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel amount to supply the engine, effectively reducing fuel consumption compared to normal driving mode. Simply put, it controls engine speed with appropriate gear selection to minimize unnecessary fuel consumption. ECO is an abbreviation, with its Chinese translation representing Ecology (environmental protection), Conservation (energy saving), and Optimization (power). ECO mode is further divided into active ECO driving mode and passive ECO driving mode. When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode is activated. ECO mode can be either active or passive. The difference lies in the fact that active ECO mode has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode button, the dashboard indicator light turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder. ECO mode automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will display the ECO indicator light accordingly. Most vehicles use active ECO driving mode, meaning there is a dedicated switch button. Therefore, ECO mode can be enabled during daily driving. However, it is unnecessary to activate ECO mode when driving over 120 km/h, during idling, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of ECO mode but also affect performance. Additionally, ECO mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, causing ECO mode to deactivate automatically. During idling or when in N/P gear or manual mode, ECO mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes delivering sufficient power to drive the vehicle, and ECO mode will not function in such scenarios.

What are the reasons for frequently failing to shift from second gear to third gear?

In the process of shifting from second gear to third gear, the reasons for frequent failure are as follows: 1. Poor coordination between throttle and clutch: During upshifting, the throttle should be released first, then the clutch pedal should be pressed, or both operations can be performed simultaneously. It is essential not to shift while pressing the throttle during the shifting process. If the throttle is not fully released when shifting, it may cause shifting hesitation. 2. The clutch is not fully depressed: Before driving, it is necessary to feel the position and depth of the clutch. If the clutch is not fully depressed when shifting, it will not only cause shifting hesitation but also lead to gear grinding in the transmission. In severe cases, it can directly damage the gears inside the transmission.

How many tons can a 750 tire bear?

750 tires can bear 10 to 12 tons. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling. They are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must possess high load-bearing performance, traction performance, and cushioning performance. Additionally, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

What is the BMW auto function?

BMW auto refers to the automatic air conditioning function. The following is a related introduction to the BMW auto air conditioning function: Automatic mode: This is the AUTO button. In this mode, once a temperature is set, the air conditioning will automatically activate when the vehicle is started, adjusting the interior temperature to the preset level in the shortest time possible. This is why there are often cases where the air conditioning blows at high intensity immediately after starting the car on hot summer days. In this mode, many mid-to-high-end models also feature automatic defogging functions, where the vehicle can automatically control the system based on fog sensors. Manual mode: On the air conditioning control panel, there are two fan symbols—one large and one small. The large symbol represents increasing the fan speed, while the small one represents decreasing it. To manually turn on the air conditioning, simply press the increase fan speed button.

What Documents Are Needed for Car Repair?

Opening an auto repair shop requires the following documents: Auto Repair License, Business License, Organization Code Certificate, Tax Registration Certificate, etc. Here are the relevant details: 1. Considerations: Choose an appropriate initial team. Starting an auto repair shop requires not only technical skills but also a team, including sales and administrative staff. A repair shop cannot be fully supported by just one or two people; more team members are needed to work together to help the initial project develop faster. The selection of initial team members should follow certain conditions and principles and should not be done blindly. 2. Office Location: Find a suitable office location. An auto repair shop has requirements for space—it cannot be too small, the roads should be accessible, and there should be adequate parking space. Only by meeting these three requirements can the shop attract car owners and generate business. Although the location can be a bit remote, it should have convenient transportation and be sufficiently large.
