What does the 'a' on the car dashboard mean?
2 Answers
The 'a' appearing on the car dashboard indicates: 1. Mileage count; 2. The auto start-stop system is turned off. Common warning lights on the dashboard include: engine oil warning light, engine fault warning light, coolant temperature warning light, brake system fault light, tire pressure warning light, battery warning light, power steering system fault light, and electronic stability control system indicator. Reasons for warning lights illuminating may include: 1. Poor fuel quality; 2. Carbon buildup inside engine cylinders; 3. Damaged, poorly connected or interrupted signals from coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, or oxygen sensor; 4. Clogged air filter.
During my daily driving, I noticed the A icon illuminated on the dashboard, which is usually the indicator light for the auto start-stop system. When the function is activated, it displays in green to remind that the vehicle has entered energy-saving mode. This system automatically turns off the engine when stopping to save fuel, which is quite convenient. However, the frequent start-stop can sometimes feel uncomfortable, especially in congested urban areas. If you want to turn it off, simply press the button with an A on the center console, and the system will deactivate with the light turning off. I've also observed that if the battery is low or the ambient temperature is extreme, the A light may flash yellow to indicate a fault, requiring prompt inspection to avoid potential driving issues. Developing a habit of glancing at the dashboard when parking can help us avoid unnecessary troubles.
