DIC Compass
Your 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) Procedure
1. Do not set the compass zone when the vehicle is
moving. Only set it when the vehicle is in P (Park).
Press the vehicle information button until PRESS
V TO CHANGE COMPASS ZONE displays. Or,
if the vehicle does not have DIC buttons, press the
trip odometer reset stem until CHANGE COMPASS
ZONE displays.
