Are there any updates or adjustments on the temperature reading. Mine is definitely off. Maybe by 5 degrees or more. Not a big deal, but It seemed to work fine up until about a week ago.

 

I believe its +/-5 degrees max you can adjust the outside temp reading. It should tell you in the owners manual.

 

Outside Air Temperature Indicator Logic Engine coolant temperature 140 °F (60 °C) or higher: If the engine coolant temperature is 140 °F (60 °C) or higher when the vehicle is turned to the ON mode, the outside air temperature shown the last time the key was turned off is displayed regardless of the current temperature measured by the outside air temperature sensor. Engine coolant temperature less than 140 °F (60 °C): If the engine coolant temperature is less than 140 °F (60 °C) or lower when the vehicle is turned to the ON mode, the current temperature measured by the outside air temperature sensor is indicated.
Information Update to the Outside Air Temperature Indicator While Driving Engine coolant temperature 140 °F (60 °C) or higher: If the temperature measured by the outside air temperature sensor is greater than the temperature on the outside air temperature indicator, the outside temperature indicator will increase by 1 °F (1 °C) per minute after the vehicle speed is greater than 19 mph (30 km/h) for more than 1 minute and 30 seconds. It continues to increase until the current outside air temperature is indicated. So, the first change to the outside air temperature indicator is 1 minute and 30 seconds after the vehicle speed exceeds 19 mph (30 km/h). If the vehicle speed drops below 19 mph (30 km/h), the indicator does not update again until the vehicle speed has increased to 19 mph (30 km/h) or more for more than 1 minute and 30 seconds again. Engine coolant temperature less than 140 °F (60 °C): If the outside air temperature is less than the indicated temperature, the temperature decreases by 1 °F (1 °C) every 2 seconds until the current outside air temperature indicated regardless of vehicle speed.

Troubleshooting If the indicator displays ― ― ―°F (― ― ―°C) for more than 2 seconds after selecting the outside air temperature display mode, the gauge is not receiving the outside temperature data from the climate control unit over the B-CAN. Check the climate control system or multiplex integrated control system for DTCs. Fahrenheit:

Calibration NOTE:
The outside air temperature indicator's displayed temperature can be calibrated ± 5 °F (± 3 °C) to meet the customer's expectations.
The outside air temperature can be calibrated by using the center display unit.



1. Turn the vehicle to the ON mode.

2. Select the HOME button on the center display unit.

3. Select the following icons in turn.
Settings
Vehicle
Meter Setup
Adjust Outside Temp. Displ





4. When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed.

NOTE: The recalibration temperature is not the value the sensor sees. Therefore the temperature can only be adjusted ± 5 °F (± 3 °C). Incorrect value = 68 °F (20 °C)




Example: Desired correction value = ＋2 °F (＋1 °C) Correct value = 70 °F (21 °C)





Desired correction value = －2 °F (－1 °C) Correct value = 66 °F (19 °C)










NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.





5. The snow mark is displayed when the temperature is 37 °F (3 °C) or less the first time you turn the vehicle to the ON mode.
