COMPASS DISPLAY
All the available overhead consoles on this model
include Compass information. While in the compass/
temperature mode, the compass will display the
direction in which the vehicle is pointed using the
eight major compass headings (Examples: north is N,
northeast is NE). The self-calibrating compass unit
requires no adjusting in normal use. The only cali-
bration that may prove necessary is to drive the vehi-
cle at 5 to 8 kilometers-per-hour (3 to 5 miles-per-
hour), on level ground in a square shaped pattern.
This will reorient the compass unit to its vehicle.
