Buick 2003 Rendezvous Owner's Manual page 171

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.
To adjust the HUD so you can see it properly:
1.
The HUD controls are
located to the left of the
steering wheel on the
instrument panel.
2.
3.
When the HUD is on, the speedometer reading will
always be displayed. The current radio station, cassette
tape or CD number and track number will only be
displayed for three seconds after the radio, tape or CD
track status changes. This will happen whenever
one of the radio controls is pressed, either on the radio
or on the audio steering wheel controls (if equipped).
4.
Start your engine and turn the dimmer knob to the
desired HUD image brightness.
The brightness of the HUD image is determined by
the ambient light conditions in the direction your
vehicle is facing and where you have the HUD
dimmer knob set. If you are facing a dark object or
a heavily shaded area, your HUD may anticipate
that you are entering a dark area and may begin
to dim.
Adjust the driver's seat. If you change your seat
position, you may have to readjust your HUD.
Press the UP or DN buttons until the HUD image is
easy to see and then press the DN button until the
HUD image is as low as possible, but remains
in full view straight ahead near the front bumper.
The HUD image can only be adjusted up and down,
not side-to-side.
To turn the image off, turn the dimmer knob
counterclockwise to OFF.
