When a yellow exclamation mark appears on the car dashboard, there are 4 possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, or lighting system fault. Below is a detailed analysis of these 4 situations: General malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Possible causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below normal range. Transmission fluid should be replaced promptly. Abnormal tire pressure: A horizontal line under parentheses with an exclamation mark in the middle represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting system fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the problem. There is also a red exclamation mark inside a circled parenthesis, which represents a brake system warning, mainly indicating brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents.

What are the reasons for the car body sweeping the line during reverse parking?

Reverse parking sweeping the line occurs because the distance between the car body and the two sides of the parking space is inconsistent, with one side being too close to the car body, leading to the line being swept. Here is relevant information: 1. Adjustment: If the first attempt to park does not find the correct spot to successfully park, timely adjustment is needed. Turn the steering wheel towards the wider side, and finally straighten the car body to successfully park. 2. Other reasons: The steering wheel is turned too early or too late, there is no time to correct or the steering wheel is turned incorrectly during correction, the brake is pressed too late, or the brake is not sensitive. These are basically the reasons for the car body crossing the line during reverse parking. Starting with full steering, the steering wheel is turned too early, and when the corner of the parking space is seen, the distance to the car body is already very close, leaving no chance to adjust the direction, and the car body can only be watched as it crosses the line.

What is the Difference Between Single-Piston and Dual-Piston?

Dual-piston calipers and single-piston calipers differ in their design methods. Below are the relevant introductions: 1. Single-piston calipers: Single-piston calipers are mostly configured in the caliper types found on mass-produced vehicles, generally belonging to the combination of one-way pistons. The brake pads on the other side are pushed by the reaction force of the caliper, hence they are also referred to as 'floating calipers.' 2. Dual-piston calipers: As for dual-piston calipers, since the inner and outer sides of the entire caliper are fixed, the clamping forces of the inner and outer brake pads are each handled by pistons on different sides, hence they are also called 'fixed calipers.' Comparing single-piston calipers with multi-piston calipers, single-piston calipers have unused areas that cannot be filled. To reduce the volume of the caliper body and maximize the piston area, dual-piston calipers were developed.

Can You Drive on the Highway with a Cracked Windshield?

Although there are no regulations prohibiting driving on the highway with a cracked windshield, it is not recommended for safety reasons. Here is relevant information: 1. External Force Impact: The front windshield of a car is generally laminated glass. When subjected to external force impact, cracks may form, allowing air to enter the interlayer of the glass, which could lead to layer separation. 2. Risks of Continued Driving: If you continue to drive, the pressure on the windshield will increase with changes in vehicle speed and wind speed, causing the crack to expand further. This not only obstructs visibility but also significantly compromises driving safety.

Should I use USB 2.0 or 3.0 for car USB drives?

USB 2.0 version is sufficient for car USB drives. The main difference between USB 2.0 and 3.0 versions lies in their data transfer speeds. Here are some precautions for using car USB drives: 1. File format: Most vehicles can only recognize music files in MP3 and WMA formats. If the downloaded music format is incorrect, it should be converted promptly; otherwise, the vehicle may fail to recognize the files. 2. Storage path: The storage path of music files should not be too deep, otherwise the vehicle may have difficulty locating them. Generally, files should be stored in the root directory of the USB drive. 3. USB drive capacity: Some vehicles, especially older models, may not support large-capacity USB drives. Therefore, when purchasing, be careful not to choose a USB drive with excessive capacity.

What are the penalties for running a red light? How many days until the violation appears?

Running a red light in a motor vehicle will result in a 6-point deduction and a fine. Generally, if you check through online traffic violation records, it takes 5 working days to appear. If you inquire at the vehicle management office or traffic police station, the record will be available the next day. Note that when checking red light violations, the record won't explicitly state "running a red light" but rather "failing to comply with traffic signal regulations." Below are the criteria for determining a red light violation: 1. Do not let the front of your vehicle cross the stop line: If the front wheels accidentally cross, you must brake immediately because if the rear wheels also cross, you will definitely be photographed. 2. Three photos: The three photos taken by electronic surveillance for running a red light are: the vehicle crossing the stop line, followed by two more showing the vehicle in the middle of the intersection and reaching the opposite side.

How to Conduct Annual Inspection for a Car Involved in a Traffic Accident?

It depends on whether the traffic accident resulted in casualties. For vehicles involved in accidents with casualties, an on-site inspection at a testing facility is required for the annual inspection. However, vehicles involved in accidents without casualties during the exemption period are exempt from inspection. The regulations for vehicle annual inspection are as follows: 1. Non-commercial passenger vehicles are exempt from on-site inspection within 6 years: Non-commercial passenger vehicles (including non-commercial cars, small and micro passenger vehicles, and from November 20, 2020, non-commercial small and micro buses with 7-9 seats, excluding minivans) are exempt from on-site inspection within 6 years, only requiring an application for an inspection mark every two years. From November 20, 2020, for private cars older than 6 years but less than 10 years, the inspection cycle is relaxed from once a year to once every two years, meaning private cars within 10 years only need on-site inspection twice, in the 6th and 8th years. For private cars older than 10 years, the original inspection cycle still applies: private cars aged 10-15 years require an annual inspection, while those older than 15 years require an inspection every six months. 2. Commercial passenger vehicles require an annual inspection once a year: Commercial passenger vehicles within 5 years require an annual inspection once a year; those older than 5 years require an inspection every six months. 3. Trucks and similar vehicles require an annual inspection once a year: Trucks and large and medium non-commercial passenger vehicles within 10 years require an annual inspection once a year, while those older than 10 years require an inspection every six months.
