Compass
Your vehicle may have a compass
in the Driver Information Center
(DIC). See Driver Information
Center (DIC) on page 5‑25 for
more information about the DIC.
Compass Zone
The zone is set to zone eight upon
leaving the factory. Your dealer/
retailer 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
necessary to compensate for
compass variance by resetting the
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
where you live, the compass may
give false readings. The compass
must be set to the variance zone in
which the vehicle is traveling.
To adjust for compass variance, use
the following procedure:
