Electrochromic Inside Rearview
Mirror
with Compass (Option)
Your vehicle may have an electrochromic inside
rearview mirror.
When on, the mirror automatically dims to the proper
level
to
minimize glare from lights behind you after dark.
The mirror also 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.
To
use
the
electrochromic mirror
only,
move the switch
at the bottom
of
the mirror to
the
M
position.
To
use the
electrochromic mirror
as
well
as
the compass. move the
switch to the
C/M
position.
To
turn both features off,
move the switch to the
OFF
position.
When the ignition is on and the mirror switch is
in
the
CIM
position, the compass display'will show
two
character boxes
for
approximately two seconds.
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 include magnetic antenna mounts,
a
magnetic note pad holder, or a similar magnetic item. If
removing these items does not correct the condition, see
your
GM
dealer for assistance.
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
liquid cleaner to enter the mirror housing.
Compass
Varia~

Under certain circumstances,
as
during a long distance
cross-country trip,
it
will be necessary to adjust the
compass
to
compensate 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
hlse readings.
