Vehicle Positioning - Cadillac Escalade EXT 2013 Owner's Manual

After-market glass tinting has
been applied to the vehicle's
windshield.
Do not apply after-market
glass tinting to the vehicle's
windows. Glass tinting interferes
with the system's ability to
receive GPS signals and causes
the system to malfunction. The
window might have to be
replaced to correct the problem.
This would not be covered by the
warranty.
For more information if the GPS is
not functioning properly, see Vehicle
Positioning on page 7 75 and
Problems with Route Guidance on
page 7 76.
