Zone variation change procedure
The difference between magnetic north and geo-
graphical north is known as variance. In some
areas, this difference can sometimes be great
enough to cause false compass readings. Follow
these instructions to set the variance for your
particular location if this happens:
1. Press and hold the
button for about 8
seconds. The current zone number will ap-
pear in the display. Release the button.
2. Find your current location on the zone map.
Refer to the illustration.
3. Press the
button repeatedly to toggle
through the zone numbers until the desired
number appears in the display. Once you
have selected a zone number, the display
will show a compass direction within a few
seconds.
Inaccurate compass direction
The compass display is equipped with automatic
correction function. If the correct direction is not
shown, follow this procedure.
1. With the display turned on, press and hold
the
button for about 10 seconds. The
“CAL” icon in the compass display will illu-
minate.
2. Calibrate the compass by driving the vehicle
in three complete circles at a maximum
speed of 5 MPH (8 km/h).
3. After completing the circles, the display
should return to normal.
● If the compass deviates from the correct
indication soon after repeated adjustment,
have the compass checked at an authorized
dealer.
● The compass may not indicate the correct
compass point in tunnels or while driving up
or down a steep hill. (The compass returns
to the correct compass point when the ve-
hicle moves to an area where the geomag-
netism is stabilized.)
● If a magnet is located in or near the overhead
console in the front of the vehicle or the
vehicle is driven where the terrestrial mag-
netism is disturbed, the compass display
may not indicate the correct direction.
CAUTION
● Do not install a ski rack, antenna, etc.,
which are attached to the vehicle by
means of a magnet. They affect the op-
eration 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.
