Mercury Mariner 2008, Owner'S Manual

Electronic compass
The compass heading is displayed as one of N, NE, E, SE, S, SW, W and
NW in the center stack display.
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antenna. Magnetic
or metallic objects placed in, on or near the vehicle may also affect
compass accuracy.
Usually, when something affects the compass readings, the compass will
correct itself after a few days of operating your vehicle in normal
conditions. If the compass still appears to be inaccurate, a manual
calibration may be necessary. Refer to
Compass zone adjustment.
Most geographic areas (zones) have a magnetic north compass point that
varies slightly from the northerly direction on maps. This variation is four
degrees between adjacent zones and will become noticeable as the
vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer to
Compass calibration adjustment.
