Solutions for abnormal brake noises: 1. If the brake produces a sharp noise when pressed, check whether the brake pads are worn out or if there are any foreign objects. If the brake pads are worn out, replace them immediately. If there are foreign objects, remove the brake pads, take out the foreign objects, and reinstall them. 2. If the brake produces a muffled noise when pressed, check whether the brake caliper has worn moving pins or fallen spring plates. If found, replace them immediately. 3. If the brake produces a hissing sound when pressed, it is recommended to first check whether there is any issue with the friction between the caliper, brake disc, and brake pads. 4. If the brake produces a rattling noise when pressed, check whether the attachments on the brake pads are loose. It is recommended to reinforce them or replace the brake pads. Automotive brake pads, also known as automotive brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration.

Reasons Why 4S Stores Do Not Recommend Installing Cruise Control

When purchasing a vehicle, some car owners request 4S stores to install cruise control. However, some 4S stores advise against it because installing a cruise control system is different from installing other vehicle accessories. The cruise control system needs to be connected to the engine control circuit, car airbags, and the central console. Such modifications can alter the original vehicle's wiring and circuits, and improper installation may even damage the car. Cruise control, also known as speed control or autonomous driving system, automatically maintains the vehicle's speed as set by the driver without the need to press the accelerator pedal, allowing the car to travel at a constant speed. Disadvantages of cruise control: The system may malfunction, which can be extremely dangerous if it occurs during high-speed driving. Cruise control is only suitable for use on highways or long-distance routes with light traffic and cannot be used on roads with complex conditions. When using cruise control, the driver's foot is freed from the accelerator pedal, leading to relaxation and reduced focus. In emergency situations, this may delay braking response, resulting in untimely braking.

How to Adjust the Rearview Mirror on an Accord?

Method for adjusting the rearview mirror on an Accord: Simply press the rearview mirror adjustment button on the driver's side door to adjust the mirror. The specific adjustment methods for the Accord's rearview mirrors are as follows: 1. For the left rearview mirror, the left side exterior mirror should be adjusted with the upper and lower halves each occupying half, meaning a 1:1 ratio between the sky and ground, with the left side taking up 3/4 and the right side 1/4 (1/4 area close to the car body), allowing visibility of the rear door handle. 2. For the right rearview mirror, since the right side is farther from the driver, the adjustment for the right side exterior mirror is slightly different from the left. The right rearview mirror should be adjusted with the upper 1/4 and the lower 3/4, with the left side taking up 1/4 and the right side 3/4 (1/4 area close to the car body), allowing visibility of the rear door handle.

Does the ETC need to be replaced after changing the license plate number?

Yes, it needs to be replaced because the license plate number bound to the ETC does not match the actual license plate number, making it unusable and unable to pass. Different vehicle types have different highway toll fees. According to the "Rules for the Use of the Non-Stop Fast Pass System," when applying for an ETC, the ETC card and OBU device are already bound to the vehicle, and the vehicle's relevant information has been imported, forming a one-to-one correspondence. If you change to a new vehicle with a new license plate, you need to cancel the original ETC and reapply for the new vehicle. If it's a new vehicle with an old license plate, you can simply update the vehicle information at an offline service center. ETC is a non-stop electronic toll collection system. ETC lanes are set up for vehicles equipped with ETC onboard devices and use electronic toll collection. The electronic toll collection system is an automatic toll system for highways or bridges. ETC deduction principle: There will be one or more ETC lanes on the highway. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle accounts with the bank, achieving the purpose of vehicles not needing to stop at toll stations to pay tolls. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC updates faster 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." It also explicitly set the goal in the main indicators of the "13th Five-Year" comprehensive transportation development that "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the usage rate of ETC passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-to-road coordination, providing comprehensive travel services for vehicle owners. This 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 device of the vehicle in front from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the vehicle in front to avoid automatically sensing and paying the toll for the vehicle in front. The recognition speed for ETC lanes is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed toll deduction. Unauthorized removal or movement of the OBU device, 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 issued or the highway service center for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in a failed toll deduction. You can follow the guidance of on-site staff to go to the manual MTC lane and use cash or card payment to pass. Poor sensing due to overly thick car windshields. Especially for vehicles that have had accidents and had their windshields replaced or for friends who have modified their front windshields, extra attention is needed.
