New brake discs typically have a standard thickness of around 15 centimeters. Brake pads need to be replaced when their thickness falls below 2 millimeters. Precautions for using brake pads: 1. They must be replaced when worn to the limit position, otherwise braking effectiveness will decrease. Brake pads are consumables that gradually wear out during use, which could even lead to safety incidents; 2. Inspect the brake pads every 5,000 kilometers driven, checking not only the remaining thickness but also the wear condition of the pads; 3. Check whether the wear on both sides is similar and whether the retraction is smooth. If any abnormalities are found, immediate replacement is necessary.

Which Gear Should Be Engaged When Running the Air Conditioner While the Car Is Stationary?

When running the air conditioner while parked, it is best to engage the P (Parking) gear. The P gear is the parking gear, and when in this position, the transmission's parking mechanism locks, preventing the vehicle from rolling. Alternatively, the N (Neutral) gear can also be used. The N gear is the neutral position, where the transmission is not under load, but the vehicle can still move. Unlike the P gear, the transmission is not locked in the N gear. Generally, vehicles have five gears: P, R (Reverse), N, D (Drive), and S (Sport). Below is an introduction to these gears: 1. P (Parking) gear, also known as the parking or starting gear: Used when the vehicle is parked and not in use. In this position, the wheels are mechanically locked to prevent rolling. The P gear should only be engaged when the vehicle is completely stationary to avoid damaging the automatic transmission's mechanical components. 2. R (Reverse) gear: Used for reversing. Never force the gear into R before the vehicle has come to a complete stop, as this can severely damage the transmission. 3. N (Neutral) gear: Used for temporary stops (e.g., at a red light). This position indicates neutral. To prevent the vehicle from rolling on a slope, always apply the brake. 4. D (Drive) gear: Used for normal driving on regular roads. 5. S (Sport) mode: When engaged, gears can be freely switched, but the shift timing is delayed to keep the engine at high RPMs for a period, enhancing the car's power. This mode increases fuel consumption.

Will I Get Points Deducted If I Run a Red Light and Stop on the Crosswalk?

If you stop on the crosswalk without continuing to drive, it is not considered running a red light but rather overstepping the stop line. According to Article 4, Item 5 of the 'Road Traffic Safety Violation Points Scoring Standards': driving or stopping at an intersection without following regulations will result in a 2-point deduction. The act of running a red light is clearly defined in the 'Road Traffic Safety Law.' Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle proceeds through an intersection during a red light, it constitutes the traffic violation of running a red light. Running a red light refers to the act where, when the vehicle is within the stop line and the signal ahead is red, the vehicle continues to move forward, with both front and rear wheels crossing the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the intersection stop line, showing the red light and license plate number. A photo of the vehicle completely crossing the stop line, showing the red light and license plate number. A photo of the vehicle continuing to move, comparing changes in the vehicle's position, showing the red light and license plate number. Capturing these three photos confirms the act of running a red light. Running a red light is not considered illegal under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If captured by surveillance cameras while yielding, manual review will not record the act of running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and if you accidentally run a red light, the traffic police will not impose penalties. Emergency situations: If you transport a critically ill patient, you can provide proof from the hospital or the rescued person to the traffic police for verification. If confirmed, the violation record can be cleared. If possible, it is best to call an ambulance to avoid accidents caused by running a red light. Traffic police direction: During peak commuting hours, traffic police may temporarily direct traffic at major intersections. Drivers must follow the hand signals of the traffic police.

What does the yellow exclamation mark in Buick mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or fault in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. The following is a detailed introduction to the exclamation mark fault lights: General faults: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Main issues include parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant being below the normal range. The transmission oil should be replaced promptly. Brake system fault: A circle with parentheses and an exclamation mark in the middle. This represents a warning for the brake system, mainly indicating a brake system fault or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Abnormal tire pressure: A horizontal line with parentheses below and an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a fault in the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the fault lights displayed on the vehicle dashboard are divided into two different colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the corresponding repair point for maintenance to eliminate potential safety hazards in time. Red indicates a very serious problem in the corresponding system. If this occurs, do not continue driving. Pull over immediately and call for professional assistance to prevent unpredictable dangers to the vehicle and personal safety from forced driving. It should be noted that when the car is started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will automatically turn off. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of potential safety hazards.
