Compass display (if equipped)
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/calibration
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 zone or calibration adjustment.
Note: Compass zone and calibration adjustments can be entered by
using the INFO and SETUP MENU controls.
Compass zone adjustment (if equipped)
1. Determine your magnetic zone by
referring to the zone map.
2. Turn ignition to the on position.
3. Start the engine.
4. From SETUP MENU, select
compass zone.
5. Press RESET control until the
message center display changes to
show the current zone setting (XX).
