The yellow exclamation mark on the Nissan Sylphy dashboard can be caused by poor fuel quality, insufficient tire pressure, or automatic transmission failure. Poor Fuel Quality: This usually occurs when poor-quality fuel is added at an unregulated gas station, leading to incomplete combustion of the air-fuel mixture during engine operation and triggering the engine warning light. While this does not affect driving safety, it can harm the engine to some extent. The solution is to opt for higher-quality fuel. Insufficient Tire Pressure: When the tire pressure monitoring system detects low pressure in one or more tires, a yellow exclamation mark appears on the dashboard. The solution is to promptly refill the tire pressure and, if necessary, visit a 4S shop for further inspection. Automatic Transmission Failure: A yellow exclamation mark may also appear if there is a transmission issue, such as a malfunction, transmission fluid below the normal range, or the need for fluid replacement. In such cases, it is advisable to avoid further driving and seek immediate inspection at a professional repair shop.
