Windshield Replacement

HUD System
The windshield is part of the HUD
system. If the windshield must be
replaced, get one that is designed for
HUD or the HUD image may look out
of focus.
Driver Assistance Systems
When a windshield replacement is
needed and the vehicle is equipped
with a front-looking camera sensor for
the Driver Assistance Systems, the
windshield must be installed
according to GM specifications for
these systems to work properly. If it is
not, there may be unexpected
behavior and/or messages from these
systems. See Object Detection System
