{CAUTION:
Leaving children, helpless adults, or pets in a
vehicle with the windows closed is dangerous.
They can be overcome from extreme heat in
warm or hot weather and suffer permanent
injuries or even death from heat stroke.
Leaving children in a vehicle with the ignition
key is dangerous for many reasons, children

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
Yfor
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:
PressYfor 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 termperature,
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
ash on the temperature display. This display will
ash 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 theYbutton, 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
Yfor
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.
2-39

Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display does
not show a compass heading, N for North, for
example, there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
in the compass/temperature button for approximately
nine seconds or until CAL is displayed.
The compass can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
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 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, your
compass could give false readings.
To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the compass/temperature button
for six seconds until a zone number appears in
the display.
