Does a slightly deformed bumper beam need to be repaired?

1. A slightly deformed bumper beam does not necessarily require repair. Here is relevant information about bumper beams: 1. The bumper beam is a device designed to absorb collision energy and mitigate impact during vehicle collisions. It consists of a main beam, energy absorption boxes, and mounting plates that connect to the vehicle. Both the main beam and energy absorption boxes can effectively absorb collision energy during low-speed impacts, minimizing damage to the vehicle's longitudinal beams and thereby fulfilling its protective role. 2. The structure of the bumper beam should ensure that the energy absorption boxes can effectively absorb energy during low-speed impacts through controlled deformation. The bumper beam is bolted to the vehicle body, making it easy to disassemble and replace.

What does the simulated training hours for Subject 2 mean?

The simulated training hours for Subject 2 refer to the minimum number of training hours required before taking the driving test. For C1 license, the required training hours for Subject 2 are 16, while for C2 license, it's 14 hours. Certain aspects of Subject 2, such as "standard operation of control devices," "vehicle inspection and adjustment before starting," "driving under adverse conditions," "mountain road driving," and "highway driving," can be taught using driving simulation equipment, totaling 4 hours. More related information is as follows: 1. Currently, driving schools have two methods to record training hours: The first method involves using the student's ID card to clock in directly on a device, but this requires students to bring their ID cards every time, which can be inconvenient if forgotten. The second method is for the driving school to issue each student a training hour card, which is the measure adopted by most driving schools. Students clock in when they start practicing in the car and clock out when they finish, recording the training hours. The advantage of this method is that all students' training hour cards are managed uniformly by the instructor, allowing them to practice and clock in at any time. 2. Recording training hours for Subject 2 is part of the driving practice: According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the maximum number of training hours per day should not exceed 4, and students must complete 16 practical training hours plus 4 theoretical training hours before they can schedule the test. Taking the most common C1 and C2 models in driving schools as examples, the training hours for Subject 1 are 12 hours, while for Subject 2, the training hours for manual transmission (C1) are 16 hours, and for automatic transmission (C2), it's 14 hours. In other words, students must complete 16 hours of training for Subject 2 before they can schedule the test.

What Causes the Steering Wheel to Make Abnormal Noises When Turning in Place on a New Car?

New cars may produce abnormal noises when turning the steering wheel in place for the following reasons: 1. If the new car has not been properly broken in, turning the steering wheel in place might cause abnormal noises, which will disappear after some use. This situation is nothing to worry about. 2. If the abnormal noise is heard coming from outside the car while turning the steering wheel, it might be due to the lack of lubrication in the plane bearing of the shock absorber. Simply open the hood and listen to see if the noise is coming from the top mount of the shock absorber to determine if it's the plane bearing making the noise. 3. Noise from the steering column dust cover. Whether driving or turning the steering wheel in place, if the noise comes from below the steering wheel, then just check the steering column dust cover. This is a friction noise caused by lack of lubrication, and applying some grease will resolve the issue.

How to Upgrade the Car Central Control Screen?

Car central control screen upgrade steps are as follows: 1. Download the firmware (remember to select the corresponding version), commonly referred to as the update.zip file. 2. After downloading, connect your phone to the central control screen via a data cable. Once successfully connected, a notification "Connected as a media device" will appear in the phone's pull-down notification bar; at this time, double-click "Computer" on your PC, and "MX4" will appear under "Portable Devices". 3. On your computer, right-click the update.zip file and select "Send to" "MX4". 4. Enter the "Documents" on your phone's desktop, locate the update.zip file, and click on "update.zip". The phone will automatically enter the upgrade interface. 5. The update process will first verify the firmware. After successful verification, it will enter "Upgrading". After a few minutes, it will return to the familiar interface. 6. After entering the system, click the "System Upgrade" icon on the desktop to view the current version number, indicating a successful upgrade.

Why is it difficult to start a car in winter?

Reasons for difficulty starting a car in winter: 1. Battery discharge: In winter, the temperature is lower, and the car's power consumption will be significantly greater than in other seasons. The battery's capacity will also decrease due to the low-temperature environment. Especially for some car owners who travel or do not drive for a long time, the battery may lose too much power, making it difficult to start the vehicle. 2. Engine oil flow obstruction: The lower the temperature in winter, the greater the viscosity of the engine oil, making it more difficult for the oil to flow. This increases the engine's resistance, resulting in difficulty starting the car in cold weather. 3. Frozen exhaust pipe: Frozen exhaust pipes mainly occur in car owners who travel short distances between home and work. Their cars are used infrequently, and the water vapor from engine combustion freezes in certain parts of the exhaust pipe. Short trips are not enough to melt this ice, and more ice forms overnight. Over time, this will affect the vehicle's starting and exhaust. 4. Engine performance: When the engine is severely worn or has faults, it can also cause difficulty starting. For example, after the cylinder and piston wear out, the sealing performance will deteriorate, the amount of air entering the cylinder will decrease, and the cylinder pressure will drop. If the cylinder pressure is too low, the engine will not start. Other issues, such as a damaged fuel pump or problems with the ignition circuit, can also prevent the vehicle from starting.

How to Turn On/Off the Vehicle Anti-Slip System?

Car anti-slip systems are enabled by default. Press and hold the ESP button to turn off the anti-slip system. The following situations are not recommended for enabling the anti-slip system: 1. When the vehicle is stuck in mud or during off-road driving, or in situations like getting stuck or other off-road conditions, appropriate wheel slip is needed to help escape or climb. Therefore, during extreme off-roading or when stuck, it's best to turn off the ESP first to ensure successful escape; 2. When encountering wheel slip while climbing a slope in rain or snow, especially when starting on snowy or waterlogged roads, wheels are prone to slipping. The system will detect the wheel slip and limit the engine's output, so it's necessary to turn off the ESP before attempting again; 3. When installing snow chains on the vehicle tires, the chains used for snow driving may interfere with the data from certain sensors in the ESP system due to changes in wheel diameter, leading to inaccurate signals. This can affect the normal operation of the ESP system, possibly causing continuous ESP intervention or triggering fault codes. In such cases, the ESP needs to be turned off.
