284 Vehicle Care

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 Messages 0 148.

Headlamp Aiming

Headlamp aim has been preset and
should need no further adjustment.
If the vehicle is damaged in a crash,
the headlamp aim may be affected.
If adjustment to the headlamps is
necessary, see your dealer.

Bulb Replacement

For the proper type of replacement
bulbs, see Replacement Bulbs
0 287.
For any bulb-changing procedure
not listed in this section, contact
your dealer.
High Intensity Discharge
(HID) Lighting
Warning
The high intensity discharge
lighting system operates at a very
high voltage. If you try to service
any of the system components,
you could be seriously injured.
Have your dealer or a qualified
technician service them.
After an HID headlamp bulb has
been replaced, the beam might be a
slightly different shade than it was
originally. This is normal.
