Compass The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak,

The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system will automatically determine when a
GPS signal is restored and provide
a heading again.
