What Does an Exclamation Mark Represent in a Car?

1 Answers

When an exclamation mark appears on the car dashboard, it indicates one of five possible scenarios: general malfunction, automatic transmission failure, brake system issue, abnormal tire pressure, or lighting system fault. Below is a detailed analysis of each situation: General Malfunction: A triangle with an exclamation mark inside signifies a malfunction in the car's general performance, components, or functions. Common causes include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor issues. It is recommended to visit a 4S shop for diagnosis and repair to identify the root cause. Automatic Transmission Failure: A yellow gear with an exclamation mark indicates an automatic transmission fault warning, suggesting either a transmission malfunction or insufficient transmission fluid. Immediate replacement of transmission fluid is advised. Brake System Issue: An exclamation mark inside a circled parenthesis serves as a brake system alert, typically signaling brake system failure or low brake fluid levels. Immediate inspection and repair of the brake system are crucial to prevent accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line within a parenthesis represents the tire pressure monitoring warning light, which illuminates when 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 indicates a lighting system fault, alerting the driver to a malfunctioning light. 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 lights to identify the issue.

What does tire buffing mean? Why buff tires?

Tire buffing refers to the process of grinding off the white barcode on the tire bead area. Tires with buffed-off trademarks are not genuine products. These are tires that were identified as problematic during factory inspections—some may still be usable but are not covered by the three-guarantee policy, meaning manufacturers assume no responsibility for any issues that arise. Essentially, these are substandard tires. Additional information: The functions of tires include: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting vehicle loads; 3. Absorbing shocks and vibrations during driving to prevent severe impacts from damaging automotive components. Tire maintenance methods include: 1. Regularly checking tire pressure; 2. Inspecting tires for bulges, cracks, cuts, punctures, or abnormal wear; 3. Removing foreign objects like stones, metal pieces, or nails from tire treads; 4. Performing wheel alignment or tire balancing.
