After driving for so many years, my first reaction when encountering a yellow light is to estimate the safe distance to decide whether to stop or proceed. A yellow light indicates that the signal is about to turn red, serving as a transition period. If the vehicle is already close to the intersection and about to enter, it can continue through safely if conditions permit. However, if there is still space, it's best to slow down and stop behind the stop line. Many inexperienced drivers take risks by rushing through yellow lights, often resulting in rear-end collisions or red-light violations. In reality, the yellow light serves as a warning to stay alert and make early judgments to avoid accidents. Remember, especially in congested urban areas, yellow lights are short, and sudden braking can easily lead to being rear-ended. Safe driving is the true skill—developing good habits ensures safety.

Introduction to Vehicle Function Buttons?

Common vehicle function buttons include the fuel tank opening button, auto start-stop button, parking radar button, central locking button, ESP on/off button, headlight washer button, etc. Below are detailed introductions to common vehicle function buttons: 1. Fuel tank opening button: Remotely opens the fuel tank cap from inside the vehicle. Vehicles equipped with this button allow the driver to open the fuel tank cap from inside the car. 2. Auto start-stop button: Many modern vehicles come with auto start-stop functionality, typically located in the lever control area. This system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a traffic light) and restarts it when it's time to move again. 3. Parking radar button: Allows the driver to manually turn the vehicle's parking radar on or off as needed. 4. Central locking button: Controls the central door locking system. Pressing this button simultaneously locks or unlocks all vehicle doors.

Will Starting at 2500 RPM Damage an Automatic Transmission Car?

Starting an automatic transmission car at 2500 RPM can cause damage because the vehicle typically shifts from lower gears progressively. 2500 RPM is considered a relatively high engine speed, and if the gear is low with excessive throttle input, it can accelerate engine wear. It is normal for a car to start at a higher RPM. Generally, the engine speed can reach 1200-1500 RPM during startup. In colder seasons, the engine speed may be even higher because too low an RPM could cause the vehicle to stall, and a slightly higher speed helps warm up the engine faster. However, during a cold start, the RPM should not be excessively high. Since the lubricant cannot adequately reach the upper parts of the engine, keeping the RPM below 2000 is more suitable to minimize wear. Once the engine stabilizes, the RPM will drop to around 800. If the RPM is too low, fuel combustion in the cylinders may be incomplete, leading to insufficient power and increased carbon buildup in the engine, which can cause significant damage over time. Conversely, if the RPM is too high, the most noticeable effect is increased fuel consumption, along with accelerated engine wear.

Can the ETC be repositioned after installation?

ETC can be repositioned after installation. Possible installation positions for ETC: For small vehicles such as cars and minivans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly illuminate. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing film of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device.

Why Does the Car Brake Make Noise?

Car brakes making abnormal noises can be attributed to the following reasons: 1. The car is new or has just had new brake pads installed, which is a normal phenomenon. 2. Rust on brake discs or pads: After parking for a long time, especially in humid weather or after rain, some rust or dirt may appear on the brake discs or pads. In this case, butter or specialized lubricating oil can be applied at the connection between the brake pads and the brake caliper. 3. Excessive wear of brake discs and pads: Both brake discs and pads are high-wear items. Every time the brakes are applied, these two components rub against each other, leading to natural wear over time. When the wear becomes excessive, abnormal noises may occur, so regular inspection and replacement are necessary.

How to Pay Vehicle Purchase Tax Online?

To pay the vehicle purchase tax, you need to log in to the online tax bureau website, quickly enter the vehicle purchase tax declaration interface through the 'Special Declaration Business' menu, select the vehicle registration location and invoice code, and enter the 8-digit invoice number. The subsequent process will be automatically populated by the system. After verifying the information, taxpayers can proceed directly with the tax payment. Alternatively, you can use a mobile app for declaration. Open the app, click 'City Services - Government Affairs - Taxation - Corporate Taxpayers (including Vehicle Purchase Tax Declaration) - Vehicle Purchase Tax' in sequence, and follow the prompts for subsequent operations. According to a joint announcement by the State Taxation Administration and the Ministry of Public Security, starting immediately, tax authorities will no longer print or issue paper vehicle purchase tax payment certificates when taxpayers handle vehicle purchase tax payment procedures. A relevant official from the tax bureau stated that the bureau has upgraded and improved the online vehicle purchase tax declaration and payment system. Through backend data exchange, electronic vehicle purchase tax payment information can be transmitted to traffic management departments such as the vehicle management office. With this, there is no need to visit the tax department. When applying for vehicle registration procedures at the public security traffic management department, there is no need to submit a paper vehicle purchase tax payment certificate.

How to Determine if the Engine is Burning Oil

Here are the methods to determine if the engine is burning oil: 1. During maintenance, fill the engine oil to the upper limit line. Check the oil level at the next maintenance cycle. If it is below the lower limit without any oil seepage or leakage, it indicates oil burning. 2. When the vehicle is in motion or idling, if a large amount of blue smoke is emitted from the exhaust pipe when the driver abruptly steps on the accelerator, this indicates a severe oil burning condition, known as acceleration oil burning. 3. In addition to blue smoke from the exhaust pipe, pulsating blue smoke can also be observed coming from the oil filler port. In this case, it indicates that the engine damage is already very serious.
