Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set to 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 conditions, such as during a long-distance,
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, the compass could give false readings. To
adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.2. Press and hold the on/off button until a zone
number appears in the display.
3. Once a zone number appears in the display, press
the on/off button quickly until the correct zone
number appears in the display. If C appears in the
compass window, the compass may need
calibration. See “Compass Calibration” explained
previously.

Manual Rearview Mirror with
OnStar
®, Compass, and
Temperature Display
The vehicle may have a manual rearview mirror with
OnStar®and an eight-point compass and temperature
display located in the upper right.
Control buttons for the OnStar
®system are at the
bottom of the mirror. See your GM dealer for more
information about the OnStar
®system. Also, see
OnStar®System on page 2-40for more information
about the services OnStar®provides.
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.
Mirror Operation
While sitting in a comfortable position, adjust the
rearview mirror so you can see clearly behind your
vehicle. Grip it in the center and move it up or down and
side to side. The day/night control, located at the
bottom of the mirror, adjusts the mirror to reduce
headlamp glare from behind during evening or dark
conditions. Push the control for daytime use; pull it for
night use.
Temperature and Compass Display
O
(On/Off):Press this button to turn the compass and
temperature display on or off. The compass display, can
show a maximum of two characters. For example, NE is
displayed for north-east.
When the ignition and the compass/temperature
feature are on, character boxes will appear for about
two seconds. After two seconds, the mirror will display
the direction the vehicle is facing and the outside
temperature.
To set the temperature in Fahrenheit or Celsius, do the
following:
1. Press and hold the on/off button until either a
ashing F or C appears.
2. Press the button again to change the display to the
desired unit of measurement. After about four
seconds of inactivity, the new unit will be locked in
and the compass/temperature display will return.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display does
not show a compass direction, 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. If the letter C should ever appear in
the compass window, the compass may need calibration.
