What does it mean that there is a snowflake mark in the BMW 5 Series?

The snowflake sign is a frost warning light, indicating that the temperature outside the car is low.

Frost warning is on, indicating that the outdoor temperature drops to a certain extent. When the temperature is lower than 4 degrees Celsius, the yellow light is on, and when it is lower than 0 degrees Celsius, the red light is on. As the temperature drops, the car should start the anti-freezing function.

If the indicator light is orange, the problem is not serious. If it is red, it must be warmed up before driving. Preheating is based on idling to water temperature of 50 degrees after starting, and then driving.

Also note that the cold car can't start the throttle, which will not only waste oil but also hurt the engine.
