yellowblue Outside Temperature Display The outside temperature is always displayed when your vehicle's ignition is on. If the outside temperature display begins to flash, this means that icy road conditions are possible. Adjust your driving if needed. The display will flash for about 30 seconds and then remain on steady. Mode Button Press this button to deliver air through the floor, middle or windshield outlets. The climate control system will stay in the selected ECC mode until the MODE button is pressed again or until the TEMP/AUTO knob is pressed. Press the up or down arrow to see the available modes. English/Metric Display You can change the temperature display from English (degrees Fahrenheit) to metric (degrees Celsius) by pressing and holding the driver's side TEMP/AUTO knob for approximately five seconds. Repeat the process to change back to English from metric. Automatic Operation Pressing the driver's side TEMP/AUTO knob sets the system for automatic operation. Once the system is set, sensors will control the air delivery mode. Air will come from the floor, middle, side or windshield outlets. The fan speed will vary as the system maintains the selected temperature setting. (All previous manually set mode settings will change back to a fully automatic mode when the climate control system is turned on this way.) Be careful not to put anything over the solar sensor located in the middle of the instrument panel near the windshield. This sensor is used by the automatic system to regulate temperature. To find your comfort zone, start with the 75_F (24_C) setting and allow about 20 minutes for the system to regulate air temperature. Adjust the temperature if necessary. If you choose 60_F (16_C), the system will remain at that maximum cooling setting and will not regulate fan speed. If you choose the temperature of 90_F (32_C), the system will remain at that maximum heating setting and will not regulate fan speed. Choosing either maximum setting will not cause the system to heat or cool any faster. 3-3
