There is also a sensor located behind the front bumper. This sensor reads the outside air temperature and helps maintain the temperature inside the vehicle. The outside temperature will be displayed in the navigation system only when the engine is running. Any cover on the front of the vehicle could give a false reading of the temperature. If the outside temperature goes up, the display temperature will not change until: • The vehicle's speed is above 15 mph (24 km/h) for five minutes. • The vehicle's speed is above 32 mph (51 km/h) for two and one-half minutes. These delays prevent false readings. If the temperature goes down, the outside temperature will be shown when you start the vehicle. If it has been turned off for less than three hours, the temperature will be recalled from the previous vehicle operation. There is also an inside temperature sensor located to the left of the ignition button. The automatic climate control system uses this sensor to receive information, so if you block or cover it, the system will not function properly. 182 Defogging and Defrosting Fog on the inside of windows is a result of high humidity (moisture) condensing on the cool window glass. This can be minimized if the climate control system is used properly. There are two modes to clear fog or frost from your windshield. Use the floor/defog mode to clear the windows of fog or moisture and warm the passengers. Use defrost to remove fog or frost from the windshield more quickly. - (Floor/Defog): Press the mode button until the defog mode appears on the display. This mode directs the air between the windshield, floor outlets and side windows. When you select this mode, the system turns off recirculation and runs the air conditioning compressor unless the outside temperature is near or below freezing. 1 (Defrost): Press this button to direct most of the air to the windshield, with some air directed to the side windows. In this mode, the system will automatically turn off the recirculation and run the air conditioning compressor, unless the outside temperature is near or below freezing. Do not drive the vehicle until all the windows are clear.
