Chevrolet 2001 Corvette Owner's Manual page 177

The HUD controls are located to the left of the
steering wheel.
To adjust the HUD so you can see it properly:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the light conditions in the direction your vehicle is
facing and where you have the HUD dimmer control
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.
It is possible for sunlight to enter the HUD causing
all of the graphics to light up. The display will return
to normal when the sunlight is no longer entering
the HUD.
2. Adjust the seat to your driving position. If you
change your seat position later, you may have to
-
re adjust your HUD.
3. Press the DISPLAY switch up or down to center the
HUD image in your view.
The HUD image can only be adjusted up and down,
- -
not side to side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn HUD
off, slide the switch to OFF.
