Mirrors
Automatic Dimming Rearview Mirror
with Intellibeam™, OnStar
® , and
Compass
Your vehicle may have an automatic dimming rearview
mirror with OnStar
® and a compass display. For more
information, see OnStar ® System on page 2-53. For more
information on Intellibeam™, see “Intellibeam Intelligent
High-Beam Headlamp Control System” under Exterior
Lamps on page 3-30.
The mirror includes 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.
Automatic Dimming
Your vehicle is equipped with an automatic dimming
rearview mirror. The automatic dimming feature is
activated whenever the vehicle is turned on and dims
only during nighttime driving.
Compass Operation
AUTO 3 : Press and hold the “auto highbeam” button
for approximately three seconds to turn the compass
on or off.
When the ignition and the compass feature are on,
the compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
If after two seconds the display does not show the
correct direction, (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, magnetic note pad holder, or a
similar magnetic item.
The compass can be placed in calibration mode
manually by pressing and holding the “auto highbeam”
button for approximately nine seconds until a C is
shown in the compass display.
The mirror can then be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the display
reads a direction.
