Your vehicle may have an electrochromic inside
rearview mirror with a compass. The mirror also
contains OnStar controls. For more information about
OnStar, see “OnStar” in the Index.

The mirror has an eight

-

point compass display in the

upper right corner of the mirror face. When on, the
compass automatically calibrates as the vehicle is
driven.

 (On/Off): This is the on/off button, located on the

lower left side of the mirror for the electrochromic
functions of the rearview mirror.

The electrochromic feature on the mirror functions
exactly the same as the base electrochromic mirror. 
See “Electrochromic Day/Night Rearview Mirror with
OnStar

R

 System” listed previously in this section for

more information.

Press the on/off button once to turn the compass on 
or off.

When the ignition and the compass feature are on, 
the compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the current compass heading.

If after two seconds the display does not show a
compass heading (N for North for example), there may
be a strong magnetic field interfering with the compass.
Such interference may be caused by a magnetic antenna
mount, note pad holder or similar object. If the letter C
should ever appear in the compass window, the compass
may need calibration.

The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads 
a direction.

The compass can be placed in calibration mode by
pressing and holding the on/off button until a C is 
shown in the compass display.
