Compass

The vehicle may have a compass in
the Driver Information Center (DIC).
Compass Zone
The zone is set to zone eight upon
leaving the factory. 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
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:
Compass Variance (Zone)

CHANGE COMPASS ZONE
displays. Or, if the vehicle does
not have DIC buttons, press the
trip odometer reset stem until
