Outside Air Temperature: Notes

The outside air temperature (OAT) can be viewed on the Info Display Module. The Info Display Module shows the outside air temperature as a damped value. The time and rate of the temperature update is based on an algorithm in the instrument cluster. Factors such as last temperature reading, current temperature reading, length of time the vehicle was off, current vehicle speed and the distance driven effect when the displayed temperature is updated. To get the vehicle to display the most accurate temperature faster, drive the vehicle. Constant moving traffic will update the display to the correct temperature more quickly than stop and go traffic.

The OAT uses a filter routine to minimize false updates due to engine heat or road heat.
