The vehicle does not activate the front radar by default. Generally, the installation of front radar depends on the owner's personal needs, combined with their vehicle and driving skills. If you are not confident in judging distances or have large blind spots, installing front radar can ensure safety. Installing front radar also offers the following advantages: Improves Parking Efficiency: When parking in tight spaces, having front radar can enhance parking efficiency and smoothness. When encountering width restrictions or barriers, front radar allows the driver to pass through more comfortably. Automatically Issues Alerts: At low speeds, the front radar can automatically detect obstacles in blind spots and issue alerts.

The front radar of BMW is automatically activated under normal circumstances, primarily used for driving assistance functions such as detecting obstacles ahead during parking or low-speed driving. It will automatically trigger an alarm sound for you. However, whether it remains constantly active depends on the mode and settings you're using. Having driven several BMW models, I've noticed that adjustments can be made in the iDrive system—parking assistance is usually activated by default when reversing or when the speed is below 20km/h, while the radar for adaptive cruise control requires manual activation of the cruise function. If there's no response after starting the vehicle, it might be due to dirty sensors or a need for a software update. My car once had false alarms, which were resolved after cleaning the sensors. In daily use, the system is quite intelligent, but don't forget to check it regularly—safety comes first.

I think BMW's front radar is quite cleverly designed—it doesn't operate at full power all the time. In parking or low-speed situations, it automatically activates to help you check blind spots, but during high-speed or normal cruising, it remains inactive unless driver assistance modes are enabled. From my experience, you can customize its behavior through the central control settings—under the vehicle menu's driver assistance options, you can choose whether to activate the radar for automatic parking functions. If the radar malfunctions, common causes include relay issues or insufficient power supply; I'd recommend restarting the vehicle first. Remember, regular maintenance can reduce failures, especially ensuring sensors aren't covered during rain or snow. This system isn't always on, but when triggered, it can be a real lifesaver.

What Causes the Noise When Pressing the Clutch Pedal?

There are several reasons why the clutch makes noise when pressed: 1. Broken drive plate steel sheet: A sharp noise is heard when the clutch is about to engage. The sound disappears when the pedal is pressed and reappears when the pedal is released. This is caused by a broken drive plate steel sheet or exposed rivet heads scraping against the pressure plate or flywheel, requiring major repairs. 2. Lack of lubrication in the release bearing: When there is insufficient lubricating oil, the balls inside squeeze against each other, producing abnormal noise, or the balls may become deformed. 3. Stagnation in the linkage system, deformation of the drive plate, or oil contamination on the friction disc: Symptoms include the clutch pedal being lifted at low speed, the vehicle jerking when starting, and a "bang" sound being emitted.

Why does the car roll back when starting on a slope?

Rolling back when starting on a slope is due to improper use of the brakes, which are not pressed firmly enough. The backward movement occurs because the clutch is not released sufficiently, resulting in insufficient power from the car. If the brake is released at this point, the car will roll back. Key points to prevent rolling back when starting on a slope: 1. Slow: Release the clutch and brake slowly to avoid stalling. 2. Vibration: Release the clutch until the car starts to vibrate, then slowly release the brake to prevent rolling back. 3. Correct operation: Slowly lift the clutch to the semi-engaged position; keep the left foot steady on the clutch pedal without moving, and gradually release the brake pedal with the right foot. When the car vibrates and shows a tendency to move forward, quickly release the handbrake, and the car will start moving. After traveling a short distance, slowly release the clutch pedal to complete the slope start.

What is the 0-100km/h acceleration time for the 10th-generation Accord 260?

The 0-100km/h acceleration time for the 10th-generation Accord 260 is 7.6 seconds. The 0-100km/h acceleration time refers to the time taken to accelerate from 0 to 100km/h, which is the most intuitive reflection of a car's power. Related introductions are as follows: Accord's powertrain technology: The 2.4L i-VTEC engine, based on Honda's unique VTEC technology, adopts direct injection, Atkinson cycle, and VTC (Variable Valve Timing Control), and introduces an EGR (Exhaust Gas Recirculation) system, improving fuel economy by 13% and increasing maximum torque by 8%. The CVT transmission uses a high-strength belt to achieve a wide gear ratio, providing efficient power delivery. Through the "G-Design Shift" control technology, it quickly responds to the driver's demands. The relationship between vehicle mileage and fuel consumption: The fuel consumption published by manufacturers is generally the constant-speed fuel consumption at 90km/h, but this does not mean that this speed is the most fuel-efficient. In fact, the faster the car goes, the greater the wind resistance, and the higher the corresponding fuel consumption. During high-speed driving, often more than half of the fuel consumption is used to overcome resistance.

Can a Temporary License Plate Be Used in Other Cities?

New cars with temporary license plates can travel to other cities, but whether they are allowed depends on the color of the plate. Below is relevant information about temporary license plates for out-of-city travel: 1. Sky-blue temporary license plates: These plates are for temporary use within the administrative jurisdiction and are only valid for vehicles driving within the city limits, so they cannot be used in other cities. 2. Brown-yellow temporary license plates: These plates allow vehicles to travel across regions. If you need to drive to another city, you must apply for this type of plate. 3. Expired temporary license plates: Additionally, if you use an expired temporary license plate and are caught by traffic police, your vehicle may be impounded, and you may face a fine of 200 yuan and a deduction of 3 points from your driving record.

Can emulsified engine oil still be used?

Emulsified engine oil cannot continue to be used. If emulsified oil is persistently used, it will damage the engine. If engine oil shows signs of emulsification, it is recommended to identify the cause of the emulsification, repair it, and then replace with fresh oil. Emulsified engine oil produces a white milky substance. Causes of engine oil emulsification: 1. Water entering the oil: Water from the heat exchanger infiltrates the oil (due to cracked water chambers); water from the combustion chamber enters the oil. 2. Gasoline mixing into the oil: Gasoline contamination in the oil may result from excessive fuel injection or insufficient air intake, leading to unburned gasoline entering the oil pan; it could also be due to poor sealing of the cylinder liner compression rings, allowing gasoline to seep into the crankcase during injection, resulting in gasoline mixing with the oil.
