Electrochromic Inside Rearview Mirror With Compass (Option); Compass Operation - GMC SIERRA 1995 Manual

Electrochromic Inside Rearview Mirror with Compass
(Option)
Your vehicle may have an optional electrochromic inside rearview mirror.
An electrochromic inside rearview mirror, when on, 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.
Compass Operation
When the ignition is on and the mirror switch is in the C/M 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 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.
