7-8 Climate Controls EXT TEMP EXT TEMP (Exterior Temperature): Press EXT TEMP to show the temperature outside the vehicle or the normal display. Pressing any other climate control button will change the display from showing the outside temperature to showing the normal display. The units for the EXT TEMP can be displayed in °F or °C. See DIC Vehicle Customization on page 4-31. By monitoring the solar radiation, the air inside the vehicle and air moving across the outside sensor, the selected temperature can be maintained while using the AUTO mode by adjusting the temperature, fan speed, and air delivery system. The system may also supply cooler air to the side of the vehicle facing the sun. The recirculation mode will also be activated, as necessary. Do not cover the sensors or the automatic climate control system will not work properly. Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. It only works when the ignition is in ON/RUN. The rear window defogger will only work when the ignition is in ON/RUN. (Rear Window Defogger): Press to turn the rear window defogger on or off. The + indicator appears in the display. The rear window defogger turns off automatically if it is left on. Notice: Do not use anything sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs would not be covered by the vehicle warranty. Do not attach a temporary vehicle license, tape, a decal or anything similar to the defogger grid. + Sensors The climate control system uses three different sensors to maintain the desired temperature. The solar sensor is located on the instrument panel, near the windshield. The interior temperature sensor is located on the instrument panel near the steering wheel and the outside temperature sensor is in front of the radiator. Remote Start Climate Control Operation For vehicles with the remote start feature and it is activated, the climate control system will automatically set the temperature to 73°F (23°C). When the ignition is turned to ON/RUN the climate control system heats and cools the inside of the vehicle using the modes that were set before the vehicle was turned off.
