COMPASSPFP:24835
System DescriptionNKS003W3
This unit displays earth magnetism and heading direction of vehicle.
DIRECTION DISPLAY
Push “COMP” switch (1) when ignition switch is in “ON” or “START”
position. The direction will be displayed.
Pushing “COMP” switch (1) a second time will turn off the display (2).
NOTE:
Do not install the ski rack, antenna, etc. which are attached to
the vehicle by means of a magnet. They affect the operation of
the compass.
The compass may not indicate the correct compass point in tun-
nels or while driving up or down a steep hill. (The compass
returns to the correct compass point when the vehicle moves to
an area where the geomagnetism is stabilized.)
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 the liq-
uid cleaner to enter the mirror housing.
Zone Variation Change ProcedureNKS003W4
The difference between magnetic north and geographical north is known as variance. In some areas, this dif-
ference can sometimes be great enough to cause false compass reading.
Follow these instructions to set the variance for the particular loca-
tion if this happens:
1. Push “COMP” switch for more than 3 seconds. The current zone
number will appear in the display.
2. Find the current location and variance one number on the zone
variation chart.
3. Push “COMP” switch until the new zone number appears in the
display. After stopping pushing the switch in, the display will
show a compass direction within a few seconds.
Correction Functions of the Compass DisplayNKS003W5
AUTOMATIC CORRECTION
The compass display is equipped with automatic correction function. If the direction is not shown correctly,
perform manual correction procedure set out below.
MANUAL CORRECTION PROCEDURE
When the display reads “C” or “CAL”, calibrate the compass by driving the vehicle in 3 complete circles at less
than 8 km/h (5 MPH).
The compass can be calibrated by driving the vehicle on everyday route. The compass will be calibrated once
it has tracked 3 complete circles.
In places where the terrestrial magnetism is extremely disturbed, the initial correction procedure may start
automatically.
