1. Set mirror assembly mirror glass in the upward position.
2. Apply protective tape to mirror housing edge.
3. Insert a suitable tool under tab (1) and gently twist to release mirror glass and holder from mirror bracket (2). Remove mirror
glass and holder by hand to fully disengage from holder bracket.
4. Disconnect two electrical connectors (3), (4) from mirror glass and holder.
INSTALLATION
1. Set mirror holder bracket and mirror glass and holder in the hor-izontal position. Ensure that metal dampener blades (1) on mir-
ror glass are aligned with ramps (2) inside plastic mirror case.
2. Connect two electrical connectors (4), (3) to the back of the mir-
ror holder.

COMPASS
COMPASS : Description (Early Production)INFOID:0000000004244474
COMPASS
• The electronic compass is highly protected from changes in most magnetic fields. However, some large
changes in magnetic fields can affect it. Some exampl es are (but not limited to): high tension power lines,
large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While
this does not happen very often, it is possible.
• During normal operation, the Compass Mirror will cont inuously update the compass calibration to adjust for
gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influ-
ences, the compass may appear to indicate false headings , become locked, or appear that it is unable to be
calibrated. If this occurs, perform the calibration procedure.
• If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, ver-
ify the correct zone variance.
Symptom Chart
Symptom CauseSolution / Reference
The compass display reads "C".
• Compass is not calibrated.
• Incorrect zone variance setting.
• Large change in magnetic field (Steel bridges, subways, concentrations of
metal, car washes, etc.)
• Compass was calibrated incorrectly or
in the presence of a strong magnetic
field. Perform Calibration. Refer to
MWI-22,
"Description (Early Production)".
Compass shows the wrong direction.
Compass does not change direction ap-
pears "Locked".
Compass does not show all the directions,
one or more is missing.
The compass was calibrated but it "loses"
calibration.
On long trips the compass shows the
wrong direction.
Perform Zone Variatio
n Setting if correct
reading is desired in that location. Refer to
MWI-22, "
Description (Early Production)".
