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,
and vehicle speed information.
Avoid covering the GPS antenna
for long periods of time with objects
that may interfere with the antenna's
ability to receive a satellite signal.
SeeBackglass Antenna on
page 7‑19 andSatellite Radio
Antenna on page 7‑20 for the
location of the vehicle's antennas. 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 the GPS signal is restored
and provide a heading again.
See
Compass Messages on
page 5‑34 for more information
on the messages that may be
displayed for the compass.
Clock (Without Date
