Automatic Dimming Rearview Mirror With Compass And Temperature Display - GMC Sierra 2005 Owner's Manual

Passenger Airbag Indicator
The vehicle may be equipped with a passenger airbag
indicator, on the mirror glass, just above the buttons.
If the vehicle has this feature, the mirror will display the
word ON, or an airbag symbol in Canada, when the
passenger airbag is enabled. For more information,
see Passenger Sensing System on page 1-74.
Cleaning the Mirror
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.
Automatic Dimming Rearview Mirror
with Compass and Temperature
Display
If the vehicle is equipped with an automatic mirror,
it will, when on, automatically dim to the proper level
to minimize glare from lights behind you after dark.

The mirror also includes a 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. The dual display can be turned on or off by
briefly pressing either the TEMP or the COMP button.
Temperature Display
The temperature can be displayed by pressing the
TEMP button. Pressing the TEMP button once
briefly, will toggle the temperature reading on and
off. To alternate the temperature reading between
Fahrenheit and Celsius, press and hold the TEMP
button for approximately four seconds until the
display blinks F and C. Press and release the TEMP
button to toggle between the Fahrenheit and Celsius
readings. After approximately four seconds of inactivity,
the display will stop blinking and display the last
selection made.
If an abnormal reading is displayed, for an extended
period of time, please consult your dealer. Under certain
circumstances, a delay in updating the temperature
is normal.
