DIC Compass

Your vehicle may have a compass in the Driver

Information Center (DIC).

Compass Zone

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:

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.

2. Find the vehicle’s current location and variance

zone number on the map.

Zones 1 through 15 are available.

3. Press the set/reset button to scroll through and

select the appropriate variance zone.

4. Press the trip/fuel button until the vehicle heading,

for example, N for North, is displayed in the DIC.

5. If calibration is necessary, calibrate the compass.

See “Compass Calibration Procedure” following.
