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: Outlet Adjustment Use the thumbwheel to open or close the outlets. Operation Tips • Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the flow of air into the vehicle. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • The vehicle's speed is above 15 mph (24 km/h) for five minutes. • Keep the area around the base of the instrument panel console and air path under the seats clear of objects to help circulate the air inside of the vehicle more effectively. • 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 the vehicle is started. 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 it is blocked or covered, the system will not function properly. 3-40
