Outside Air Temperature Display

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 is affecting the true outside temperature.

Since underhood heat can also affect the outside temperature while the engine is running, it may take several minutes of driving before the display updates to the actual outside temperature.

Passenger’s Side Temperature Knob: Turn this knob clockwise or counterclockwise to manually raise or lower the temperature on the passenger’s side of the vehicle.
