Your vehicle may have this feature. When on, an automatic dimming mirror automatically dims to the proper level to minimize glare from lights behind you after dark.
The mirror also includes a duel display in the upper right corner of the mirror face. The compass reading and the outside temperature will both appear in the display at the same time.
(On/Off): This is the on/off button.Press the on/off button, located to the far left, briefly to turn the comp/temp display on or off.
If the display reads CAL, you will need to calibrate the compass. For more information on calibration, see "Compass Calibration" later in this section.
To set the readings to appear in either Fahrenheit or Celsius do the following:
The automatic dimming mirror function is turned on automatically each time the ignition is started. To operate the automatic dimming mirror do the following:
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 on/off button for about nine 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.
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 of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance.
To adjust for compass variance do the following:
When cleaning the mirror, use a paper towel or similar material dampened with glass cleaner. Do not spray glass cleaner directly on the mirror as that may cause the liquid cleaner to enter the mirror housing.
