Information 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 air temperature indicator increases 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 continues 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 does not update again until the vehicle speed has 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 outside air temperature is less than the indicated temperature, the temperature decreases 1 °F(1 °C) every 2 seconds until the current outside air temperature is indicated regardless of vehicle speed.
