If The Hud Image Is Not Clear; Care Of The Hud - Pontiac 2004 Grand Prix Owner's Manual

The HUD will "remember" the last display format
selected. When the vehicle is started if the last format
displayed was Format One or Format Three, then
Format One will be displayed.
If the last format was Format Two, then Format Two
will be displayed.
The HUD will automatically dim and brighten to
compensate for outside lighting.
The HUD display can temporarily light up depending on
the angle and position of the sunlight on the display.
This is normal and will change when the angle of
the sunlight on the HUD display changes.
Polarized sunglasses could also make the HUD image
harder to see.

Care of the HUD

Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the HUD image.
To clean the HUD, spray household glass cleaner on a
soft, clean cloth. Wipe the HUD lens gently, then dry
it. Do not spray cleaner directly on the lens because the
cleaner could leak into the unit.

Is the HUD image too bright?

Are the windshield and HUD lens clean?
The windshield is part of the HUD system. If you ever
need a new windshield, be sure to get one designed for
HUD. If you don't, the HUD image may look blurred
