Outside Temperature: Notes

NOTE: Engine temperature or the vehicle experiencing a "hot soak" condition can increase the temperature near the ambient temperature sensor. The displayed temperature may appear to update slowly until the vehicle is driven and the compass performs directional updates.

The displayed outside temperature information is stored within the compass/temp module. When the Compass/Temperature Module is first powered up, it retrieves the temperature data from the module memory. The memory temperature is compared with the temperature received from the ambient temperature sensor (ATS). The colder of the two temperatures is displayed.
