A triangle with an exclamation mark indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault warning in vehicles. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark inside, a red circle with an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Brake System Fault: A circle with an exclamation mark in the middle represents a brake system warning, mainly indicating brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the vehicle's tire pressure is too low. Check the vehicle's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in 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 issue.

Will the Car Continue to Rust After Touch-Up Painting?

Do not leave paint peeling on your car unattended for long periods, as it can lead to rust. During daily driving, minor scratches are inevitable. Rust primarily occurs when the metal body panels are exposed to the external environment after collisions or scrapes. Occasional scratches, small stones hitting the body while driving, and prolonged outdoor parking can cause rust to appear even on the best-maintained cars. More relevant information is as follows: Note 1: Areas prone to water accumulation, such as the inner and outer edges of wheel arches, the bottom and corners of doors and trunks, are susceptible to rust over time. If the drainage holes at the bottom of the doors are blocked or not functioning smoothly, water seeping in during rain or driving can accumulate inside the doors, leading to rust from the inside out. By the time it's noticed, it may be difficult to address. Note 2: Car owners can take the following measures to prevent rust: regularly ensure that drainage holes in doors and other parts of the body remain clear. Areas around keyholes, window seals, and moving parts of wiper arms are also prone to rust and should be frequently wiped with a dry cloth.
