Center (DIC).
Compass Zone
Your dealer will set the correct zone
for your location.
Under certain circumstances, such
as during a long distance
cross-country trip or moving to a
new state or province, it will be

zone through the DIC if the zone is
not set correctly.
Compass variance is the difference
between the earth's magnetic north
and true geographic north. If the
compass is not set to the zone
