Precautions for Compass

NKS002JE

NOTE:

●

Do not install the ski rack, antenna, etc. which is attach to the vehicle with a magnet base. It affects the
operation of the compass.

●

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 it may cause the liquid cleaner to enter the mirror housing.

System Description

NKS002JB

●

This electronic compass is able to display 8 primary directions:
N, NE, E, SE, S, SW, W, NW.

●

The inside mirror switch is used to operate the compass and
automatic anti-glare system.

Switch Operation

NOTE:
For further details of the compass and automatic anti-glare system, refer to Owner's Manual

●

All standard compasses determine direction relative to Magnetic North; however, this electronic compass
is designed to display direction relative to True North.

●

The difference between Magnetic North and True North varies from place to place across the surface of
the earth.

●

This electronic compass must be “told” approximately where it is on the earth’s surface so that the Mag-
netic North reading can be properly converted into a True North display.

●

To tell the electronic compass where it’s at, the earth is separated into numbered “Zone Variances”. The
Zone Variance number in which the compass is to function must be entered into this electronic compass.

●

Each zone is magnetically about 4.2

°

 wide. Typically, anything under 22.5

°

 total zone change is not

noticed on the electronic compass display. However, over 22.5

°

, a reading may be off by one or more pri-

mary directions.

●

On long trips, a vehicle may leave its original zone and enter one or more new zones. Generally, you do
not need to reset the compass zone if you travel between 3 or 4 zones, such as business travel or vaca-
tion. The typical driver will not notice any difference on the display within 3 or 4 zones. However, if the
vehicle is “permanently” moved to a new location, it is recommended that the compass zone be reset.

Troubleshooting

NKS002TZ

●

The electronic compass is highly protected from changes in most magnetic fields. However, some large
changes in magnetic fields can affect it. Some examples 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 continuously update the compass calibration to adjust
for gradual changes in the vehicle’s magnetic “remnant” field. If the vehicle is subjected to high magnetic
influences, 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,
verify the correct zone variance.

Troubleshooting Chart

Symptom

Cause

Solution / 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, carwashes, etc.)

●

Compass was calibrated incorrectly or in 
the presence of a strong magnetic field.

Perform Calibration.
Refer to 

DI-223, "Calibration Procedure"

 .

Compass shows the wrong direction.

Compass does not change direction – 
appears “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 Variation Setting if correct 
reading is desired in that location.
Refer to 

DI-223, "Zone Variation Setting 

Procedure"

 .

Compass does not work – No direction is 
displayed.

Compass not turned ON.

Check for green LED indicator (inside mir-
ror switch).

No power to inside mirror.

Check power supply circuit.
