What does the snowflake symbol on the car dashboard indicate?
2 Answers
When a snowflake symbol appears on the car dashboard, it indicates low outside temperature, warning of potential icy road conditions and prompting the driver to exercise caution. This is a normal phenomenon. In some vehicle models, it may represent the snow mode. Additionally, there is a malfunction scenario where a faulty outdoor temperature sensor can also trigger the snowflake symbol. There are two situations when a snowflake appears on the car dashboard: 1. When the outside temperature is too low (below 4°C), the outdoor temperature sensor detects the temperature and transmits it to the dashboard, which then illuminates the snowflake light to alert the driver to drive carefully. 2. If the car's outdoor temperature sensor is damaged, it may collect incorrect temperature data and transmit it to the dashboard. Regardless of whether the collected temperature is lower or higher than the actual temperature, the dashboard will display the snowflake light, which in this case serves as a malfunction indicator.
I've been driving for nearly 30 years, and seeing the snowflake icon on the dashboard is very common, especially during autumn and winter. It's mainly a low-temperature warning signal, indicating that the outside temperature has dropped below freezing, around 4°C or colder, and the roads may become icy and slippery. As an experienced driver, when I see this light come on, I instinctively slow down, maintain a safe distance, and avoid sudden braking or sharp turns. I vividly remember once sliding on icy mountain roads; fortunately, I had slowed down in advance and avoided any trouble. Before winter, I make it a habit to check tire pressure and tread depth to ensure good anti-skid performance. If the light stays on continuously, it might be a temperature sensor malfunction, and I recommend getting it checked at a repair shop promptly. Overall, it's a friendly reminder to help drivers safely adapt to weather changes.
