A new outside temperature reading will be displayed
if the vehicle has been off for more than three hours.
If the vehicle has been off for less than three hours,
the old temperature reading may be displayed because

Underhood heat can also affect the outside temperature
while the engine is running. It may also take
several minutes of driving before the display
updates to the actual outside temperature.
