GAUGES, METERS AND SERVICE REMINDER INDICATORS D Barometer mode D Altimeter mode In barometer mode, the atmospheric pressure in the vehicle is displayed. The displayed atmospheric pressure ranges from 17.8 IN.HG (600 hPa) up to 31.0 IN.HG (1050 hPa). The displayed value is updated every 2 seconds. The displayed value may deviate from the actual atmospheric pressure depending on opening or closing of the windows and doors and the driving conditions. In altimeter mode, the approximate altitude is displayed. The displayed altitude ranges from -1500 ft. (-500 m) up to 13000 ft. (4000 m). As the altitude value is converted from the atmospheric pressure, it can be easily affected by air motion and temperature, so the indication may vary. The indicated altitude of a single position may deviate according to the atmospheric pressure and temperature. The displayed value is updated every 2 seconds. RECTIFICATION OF THE ALTITUDE Rectification is valid only when the correct altitude is known. While the altitude mode is on the display, push the " " or " " button to increase or decrease the altitude by 50 ft. (10 m). To reset the rectified altitude, push and hold the "RESET" button for more than 1 second. 72
