Buick 2004 Park Avenue Owner's Manual page 137

Be sure to continue scanning your displays, controls
and driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel, you may not see something important, such as a
warning light.
Notice: If you try to use the HUD image as a
parking aid, you may misjudge the distance and
damage your vehicle. Do not use the HUD image as
a parking aid.
The HUD controls are
located in the overhead
console.
1. Start your engine and slide the HUD dimmer switch
all the way up.
The brightness of the HUD image is determined by
whether the headlamps are on or off, and where
you have the HUD dimmer switch set.
2. Adjust the seat to a comfortable driving position.
Keep pressing the top arrow on the image height
adjuster to raise the image as far as possible.
3. Keep pressing the bottom arrow on the image
height adjuster to move the image as low as
possible, while still keeping it in full view.
4. Slide the dimmer switch downward until the HUD
image is no brighter than necessary.
To turn the HUD display off, slide the dimmer switch all
the way down.
If the sun comes out, the sky becomes cloudy, or if you
turn your headlamps on, you may need to adjust the
HUD brightness using the dimmer switch. Polarized
sunglasses could make the HUD image harder to see.
To change the display from English to metric units,
push the ENG/MET button located to the left of
the steering column.
