Temperature Display The temperature can be displayed by pressing the TEMP button. Pressing the TEMP button once briefly, will toggle the temperature reading from Fahrenheit (°F), Celsius (°C), to off. Compass Calibration The compass may need calibration from time to time. In order to calibrate, CAL must be displayed in the mirror compass windows. If CAL is not displayed, push in the COMP button for approximately six seconds or until CAL is displayed. The compass can be calibrated by driving the vehicle in circles at five mph (8 km/h) or less until the display reads a direction. Automatic Dimming Mirror Operation Press the COMP button to turn the automatic dimming feature on and off. An indicator light on the bottom of the mirror face will be on when the automatic dimming feature is on. Compass Variance Compass variance is the difference between earth's magnetic north and true geographic north. If not adjusted to account for compass variance, your compass could give false readings. The mirror is set in zone eight upon leaving the factory. It will be necessary to adjust the compass to compensate for compass variance if you live outside zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass Operation Press the COMP button once briefly to turn the compass on or off. When compass feature is on, the compass will show the direction the vehicle is traveling, with a maximum of two characters. 2-37
