11. Ambient temperature gauge
This display indicates the air temperature outside your car. A "snowflake" symbol in the text window is displayed when the temperature is in the range of 23 - 36° F (-5 - +2° C).
Please note that this symbol does not indicate a fault with your car.
At low speeds or when the car is not moving, the temperature readings may be slightly higher than the actual ambient temperature.
