Pontiac 2003 Bonneville Owner's Manual page 137

Notice: Although the HUD image appears to be
near the front of the vehicle, do not use it as
a parking aid. The HUD was not designed for that
purpose. If you try to use it as such, you may
misjudge the distance and damage your vehicle.
The HUD controls are located to the left of the steering
column.
1. Start your engine and turn the HUD INTENSITY
knob all of the way clockwise to MAX (Maximum).
The brightness of the HUD image is determined
by ambient light, and where you have set the HUD
INTENSITY knob.
2. Adjust the seat, if necessary, before setting the
height using the IMAGE switch.
Press and hold the top of the IMAGE switch,
raising the HUD image as far as possible. Then
press on the bottom of the HUD IMAGE switch to
move the image down, so the image is as low
as possible, but in full view.
3. Turn the INTENSITY knob counterclockwise until
the HUD image is no brighter than necessary. To
turn the HUD off, turn the HUD INTENSITY knob all
the way counterclockwise.
If the sun comes out, or it becomes cloudy, or if you
turn on your headlamps, you may need to adjust
the HUD brightness using the HUD INTENSITY knob.
Polarized sunglasses could make the HUD image harder
to see.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity
of the HUD image.
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 fluid
could leak inside the unit.
