Update to the outside air temperature indicator while driving

Engine coolant temperature is 140°F (60°C) or higher:

If the temperature measured by the outside air temperature sensor is greater than the temperature on the outside air temperature indicator, the outside temperature indicator will increase by 1°F (1°C) per minute after the vehicle speed is greater than 19 mph (30 km/h) for more than 1 minute and 30 seconds. It will continue to increase until the current outside air temperature is indicated. So, the first change to the outside air temperature indicator is 1 minute and 30 seconds after the vehicle speed is greater than 19 mph (30 km/h). If the vehicle speed drops below 19 mph (30 km/h), the indicator will not update again until the vehicle speed is increased to 19 mph (30 km/h) or more for more than 1 minute and 30 seconds again.

Engine coolant temperature is less than 140°F (60°C):

If the engine coolant air temperature is less than 140°F (60°C), the temperature displayed increases 1°F (1°C) every 2 seconds until the current outside air temperature is displayed.

If the outside air temperature is less than the indicated temperature, the temperature will decrease 1°F(1°C) every 2 seconds until the current outside air temperature is indicated regardless of vehicle speed.
