Compass
The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass
receives its heading and other
information from 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.
See Backglass Antenna
on
page 619
and Satellite Radio
Antenna
on page 619
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
GPS signal is restored and provide
a heading again. See Compass
Messages
on page 434
for more
information on the messages that
may be displayed for the compass.
