Abstract:
A method of controlling an initial external temperature display in a vehicle may include comparing an ignition-off time with a first threshold and displaying a current reading from an outside ambient temperature sensor when the ignition-off time equals or exceeds the first threshold. The method further includes comparing at least one secondary condition with at least one secondary parameter when the ignition-off time falls below the first threshold and selecting and displaying a reading based on the comparison of the at least one secondary condition with the at least one secondary parameter. This comparison can include comparing a previous ignition-on time with a second threshold and comparing a sum of the ignition-off time and a stored amount with a third threshold when the previous ignition-on time equals or falls below the second threshold. Alternatively, this comparison can include comparing an engine water temperature with a temperature threshold.
