Your vehicle may have this feature. When on, the automatic dimming mirror dims to the proper level to minimize glare from lights behind you after dark.
The mirror has a dual display in the upper right corner of the mirror face that shows the compass reading and the outside temperature.
Control buttons for the OnStar® system are at the bottom of the mirror. See OnStar® System for more information about the services OnStar® provides.
: This button is used as a toggle for changing displays and as an on/off toggle during a function.Your vehicle may also have a Rear Vision Camera. See Rear Vision Camera (RVC) for more information.
Slide-Out Video Feature Enable
Press and hold for three seconds to toggle the slide-out video feature on/off. An indicator light will turn on at the time the slide-out video is enabled. If the slide-out video feature is on, each time the vehicle is put into reverse, the slide-out video screen will extend. See Rear Vision Camera (RVC) for more information.
The slide-out video feature will remain in the current on/off state each time the ignition goes through its cycle.
Slide-Out Video Cleaning
The slide-out video has to be enabled before the cleaning process can take place.
| • | Press and hold for six seconds or until the lower indicator light turns on. |
| • | While extended for cleaning, neither the screen nor the camera will have power. |
| • | Press briefly or wait 30 seconds to end cleaning. The screen will then retract. |
Automatic Dimming Mirror Operation
The automatic dimming mirror comes on each time the ignition is turned to start. To turn the automatic dimming feature off or back on, press and hold for nine seconds. The indicator light on the mirror is lit when the automatic dimming feature is on.
Temperature Display
To adjust between Fahrenheit and Celsius:
| • | Press for approximately four seconds to toggle the display from F (Fahrenheit) to C (Celsius) to OFF. |
| The temperature display will remain in its current state each time the ignition goes through its cycle. |
| • | At start up, if the vehicle has been off for less than two and a half hours, and the last stored temperature was less than the current temperature, the sensor will increase 1°F every two minutes until the correct temperature is displayed. |
| • | If the vehicle has been off more than two and a half hours, or the last stored temperature is greater than the current temperature, the current temperature immediately displays. |
| • | If the temperature is 37°F (3°C) or lower, ICE will flash on the temperature display. This display will flash every two seconds for a period of one minute. |
If an abnormal temperature reading is displayed for an extended period of time, see your dealer/retailer. Under certain circumstances, a delay in updating the temperature is normal.
Compass Display
Press the button, located at the bottom of the mirror, next to the OnStar® control buttons to turn the compass/temperature display on or off.
If CAL is not displayed, press and hold for 15 seconds, or until CAL is displayed. The compass is now in calibration mode. For more information, see "Compass Calibration" following.
The mirror can be calibrated in one of two ways:
| • | Drive the vehicle in circles at less than 5 mph (8 km/h) until the CAL is no longer displayed in the compass window. Then continue to drive to make sure all eight directions are available. |
| • | Drive the vehicle under normal operating conditions. |
Compass Variance
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 the vehicle is outside of zone eight. Under certain circumstances, as during a long distance cross-country trip, it will be necessary to adjust for compass variance. Compass variance is the difference between earth's magnetic north and true geographic north. If not adjusted to account for compass variance, the compass could give false readings.
To adjust for compass variance:
- Find your current location and variance zone number on the following zone map.
- Press and hold for 12 seconds until a zone number appears in the display. The compass is now in zone mode.
- Keep pressing the until the desired zone number appears in the display. Release the button. After approximately four seconds of inactivity, the new zone number will be locked in and the compass/temperature display will return.
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 could cause the liquid cleaner to enter the mirror housing.
