Abstract:
1. A method of controlling an initial external temperature display in a vehicle, the method comprising: comparing an ignition-off time with a first ignition-off time threshold; displaying a current temperature reading from an outside ambient temperature sensor when said ignition-off time one of equals and exceeds said first ignition-off time threshold; comparing at least one secondary condition with at least one secondary control parameter when said ignition-off time is less than said first ignition-off time threshold; and selecting and displaying a temperature reading based on the comparison of said at least one secondary condition with said at least one secondary control parameter, wherein comparing at least one secondary condition with at least one secondary control parameter further comprises: comparing a sum of said ignition-off time and a stored time amount with a third time threshold when a previous ignition-on time is equal to or falls below a first ignition-on time threshold.
