The reasons for the noise when stepping on the brake in P gear are as follows: 1. The sound of the gear lock, which is a normal phenomenon. When the brake is pressed, the gear unlocks, resulting in a clicking sound. 2. The noise caused by parking in P gear without engaging the handbrake. After locking, the vehicle's braking relies on the pawl lock. When the vehicle needs to move out of P gear, the pawl lock is released first, which produces a noise. 3. The noise caused by a slight deviation in the length of the brake pad's steel backing. In this case, you can press the brake, shift to drive gear, let the car move slightly, then shift to reverse gear, let the car move slightly again, and then shift back to drive gear to see if there is a noise every time. If there is, it indicates that the brake pad gap has increased, and the brake pads need to be replaced promptly.

Can You Still Drive When the Transmission Warning Light Comes On?

Generally, if the transmission warning light comes on and there are no particularly obvious faults, you can still drive cautiously at low speeds. However, if there are clear transmission issues, you should not drive on the road. Possible reasons for the transmission warning light coming on: 1. False alarm: A fault code is reported, but the transmission works normally. This may be due to an operation that temporarily exceeded the computer's control range, causing the computer to report a fault code. You can first clear the code and then check if it reappears. 2. Minor fault: The transmission has no obvious issues, but further inspection based on computer diagnostics reveals a minor fault that does not significantly affect normal driving. However, it should still be identified and resolved promptly. 3. Major fault: Such faults can be detected visually or through driving experience and severely impact the engine's normal operation. Immediate repair is required.

What to Do When the Vehicle in Front Blocks Your View and You Run a Red Light?

In general, if a motor vehicle is photographed running a red light while following another vehicle, it is usually because the driver rushed through the intersection when the signal was changing. This behavior can only be penalized as running a red light. However, if it is confirmed that the signal light was obstructed by the vehicle in front, the driver can apply for a reconsideration after being penalized. Drivers should maintain sufficient visibility to see the traffic signals ahead and ensure a safe braking distance. Penalty Points for Running a Red Light: According to Article 2, Section 1, Clause 2 of the "Scoring Standards for Road Traffic Violations," driving a motor vehicle in violation of traffic signal lights results in a deduction of 6 points. Article 3, Section 1, Clause 8 states that driving a motor vehicle in violation of prohibitory signs or markings results in a deduction of 3 points. How to Check for Red Light Violations: You can check for red light violations through the "Traffic Management 12123" app. After opening the app, log in with your ID card, find the option for violation handling, and click on it. In the violation handling section, you can see the current status of your vehicle. If there are any violations, the specific details will be displayed. Visit the office halls of the traffic police departments in various districts and counties to check using the touch query terminals. Log in to the external service websites of the public security traffic management bureaus of various cities: find the vehicle violation query section, enter your license plate number and engine number, and click to query.

What are the reasons for car shaking during driving?

There are several reasons why a car may shake during driving: 1. Ignition system issues: Problems such as excessively large or small spark plug gaps, excessive carbon buildup on spark plugs, damaged ignition coils, loose or leaking high-voltage wires, etc. If the idle is unstable, the entire ignition system should be checked. 2. Excessive carbon buildup: Excessive carbon deposits on the engine, throttle, and fuel injectors are the most common cause of engine shaking. Since carbon absorbs gasoline, excessive carbon can be drawn into the cylinders for combustion, leading to fluctuating concentrations of the air-fuel mixture in the cylinders, which is especially noticeable during cold starts. 3. Abnormal water temperature: The engine operates within a specific temperature range. If the water temperature is too high, it can cause early ignition timing, changes in the air-fuel mixture, thinning of engine oil viscosity, and reduced lubrication performance. Common causes of shaking due to high water temperature include insufficient coolant, a stuck thermostat, a non-functioning fan, or an inaccurate temperature control switch. These issues should be addressed to resolve the shaking. 4. Low cylinder pressure: Engines have 3, 4, 5, 6, or 8 cylinders. If one cylinder is not functioning properly, it can lead to engine shaking due to misfiring. Use a cylinder pressure gauge to check the cylinder pressure. Xinba can be used to address low-pressure issues. Xinba is particularly effective for low and unbalanced cylinder pressure and can be added to the engine oil or directly into the cylinders to restore balanced pressure. 5. Low idle speed: The engine idle speed is preset in the car's computer. If the RPM drops below a certain range, the car's computer will automatically adjust it. If the idle speed is too low and causes shaking, it indicates that it is beyond the computer's control range. Check the idle control valve, throttle, air flow meter, vacuum sensor, and adjust the ignition timing to increase the idle speed.

What to Do When a Car Rolls Backward on a Slope?

When starting a car on an uphill slope, it is prone to rolling backward. To prevent this, simply pull the handbrake tight, slowly lift the clutch to the engagement point, then immediately stabilize the clutch and release the handbrake. This will prevent the car from "rolling back." If the slope is steep, you may need to gently press the accelerator before releasing the handbrake. Steps for starting on a slope: 1. Press the brake and clutch pedals to prepare for starting. 2. Press the brake pedal and slowly lift the clutch pedal to the half-engagement point. 3. Release the brake pedal, press the accelerator pedal, and, while maintaining the half-engagement state, release the handbrake and slowly lift the clutch pedal. 4. After gaining speed, adjust the accelerator pedal and fully release the clutch pedal.
