Why does a manual transmission make noise at idle but the noise disappears when the clutch is pressed?

Can Temporary License Plates Apply for ETC?

As long as ETC is applied for, you can use the ETC lane. Because ETC is an automatic charging device, the ETC equipment identifies the ETC electronic tag on the vehicle, and the fee is deducted from the balance of the ETC electronic tag, which has little to do with whether a temporary license plate is used. ETC charging principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, and using computer networking technology to settle accounts with the bank in the background, the purpose of vehicles not needing to stop at road and bridge toll stations to pay road and bridge fees is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: eliminates the hassle of waiting in line; Green and environmentally friendly: green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and decreasing pollution; Save wear and tear: reduces costs, decreases the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improve efficiency: the efficiency of passing through ETC lanes can theoretically be increased by 2-3 times or more, making traditional ETC updates faster, newer, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban agglomerations will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased," and explicitly proposed in the main indicators of the "13th Five-Year" comprehensive transportation development that "by 2020, the ETC usage rate of road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate of passenger vehicles, the future will also promote the use of ETC for trucks, explore the deep integration of the ETC system with the development direction of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, and provide car owners with comprehensive travel services, which means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the ETC equipment failure of the vehicle in front or the absence of ETC equipment, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The speed for ETC lane recognition is 20km/h. If the speed is too fast, the vehicle equipment information cannot be read, which will also lead to charging failure. Unauthorized disassembly or movement of the OBU equipment, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was applied for or the highway service office for testing. Non-manual loosening or detachment only requires reactivation. When using a debit card to bind ETC, insufficient balance will also lead to charging failure. You can follow the guidance of on-site staff to the manual MTC lane and pass by using cash or card. Poor sensing due to overly thick car windshields. Especially for vehicles that have been repaired after accidents and had their windshields replaced, or friends who have modified their front windshields need to pay attention.

Why Can't the Right Rear Door Be Opened from the Inside?

It may be due to the child lock being engaged. It is recommended to check the sliding switch on the side of the right rear door. In most cases, this is a normal phenomenon. Generally, there is a child lock on the rear door locks, which serves to prevent children from mischievously pulling open the door from the inside without adult supervision, thereby avoiding potential dangers. More relevant information is as follows: 1. Location: The child lock toggle is usually located on the side of the rear door, accompanied by an image of two locks. Toggling the switch to the lock position activates the child lock, preventing the door from being opened from the inside; it can only be opened from the outside under normal circumstances. Toggling the switch to the unlock position deactivates the child lock, allowing the door to be opened from the inside when the vehicle is fully unlocked. 2. Note: If the child lock is not engaged and the vehicle is fully unlocked, but the door still cannot be opened from the inside, it may indicate a malfunction in the door lock mechanism. In such cases, inspection and repair should be considered based on the situation.

What Causes Abnormal Noise When Pressing the Clutch in a Manual Transmission?

Abnormal noise when pressing the clutch in a manual transmission generally falls into two scenarios: 1. Clutch wear: Many drivers have the habit of keeping their foot on the clutch pedal even after shifting gears. Maintaining this habit for a long time can damage the clutch, leading to wear on the clutch plate and resulting in abnormal noise. 2. Damage to clutch transmission components: When the clutch pedal is pressed, a distinct abnormal noise can be heard from the clutch area, which becomes more noticeable when the pedal is released. The main causes for this situation include: broken clutch pressure plate springs or loose release bearings; fractured clutch discs; broken, excessively worn, or broken adjustment bolts of the clutch release levers.

Why Can't Some Used Cars Be Transferred?

At this time, the vehicle still has unresolved issues, such as used cars still under mortgage, used cars that have been modified or altered without authorization, including changes in cargo weight or passenger capacity, and used cars with unresolved violations or accidents cannot be transferred. Below are specific details: 1. Other situations where transfer is not possible: If the used car does not meet the local standards for relocation in or out, it cannot be transferred. 2. Corresponding risks: The ownership of the vehicle does not belong to you, and the money spent is essentially wasted. Without the transfer, insurance cannot be obtained, and if there is no third-party liability insurance, any accidents causing harm to a third party will require full compensation to be paid out of pocket.

How Often Should Valvoline Full Synthetic Motor Oil Be Changed?

Valvoline full synthetic motor oil can be changed once a year or every 10,000 kilometers, whichever comes first. Below are some related details about motor oil: 1. Function: Motor oil, also known as engine lubricating oil (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and absorb shocks, earning it the nickname "the lifeblood of a car." 2. Composition: Motor oil consists of two main components: base oil and additives. The base oil is the primary ingredient of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, providing new characteristics and making them an essential part of lubricating oil.

What documents are required for driver's license review?

Documents required for driver's license review include: original driver's license and its copy, original ID card and its copy, and several recent one-inch white background ID photos. The following is an introduction to driver's license annual review: 1. Large vehicle driver's license: Drivers holding A1, A2, B1, or B2 licenses should go to the traffic management department of the public security authority for review within thirty days after the end of each scoring cycle. However, if there is no record of demerit points during a scoring cycle, the review for that cycle is exempted. 2. Small vehicle driver's license: Drivers holding C1 or below licenses will be reviewed when renewing their licenses upon expiration. However, if they are involved in a traffic accident resulting in death with equal or greater responsibility without their motor vehicle driver's license being revoked, they should go to the traffic management department of the public security authority for review within thirty days after the end of the scoring cycle.
