Head-Up Display (HUD)
{WARNING
If the HUD image is too bright,
or too high in your field of view, it
may take you more time to see
things you need to see when it is
dark outside. Be sure to keep the
HUD image dim and placed low in
your field of view.
For vehicles with the Head-Up
Display (HUD), you can see some
of the driver information that

out toward the front of the vehicle.
The HUD consists of the following
information:
.Speedometer

Indicator (If Equipped)
These displays on the HUD are
for use when using the manual
paddle shift controls to shift the
transmission. See
“Manual
Paddle Shift” inAutomatic
Transmission on page 9‑28.
.Shift Light
This light is used for
performance driving to
indicate that the vehicle's
best performance level has
been reached to shift the transmission into the next higher
gear. An arrow pointing up will
light up on the display just prior
to reaching the engine fuel
cut-off mode. This cut-off is
about 6,500 RPM for the
LS3 engine, 6,600 RPM for
the LS9 & ZR1 engines and
7,000 RPM for the LS7 engine.

To adjust the HUD so it can be seen
properly, do the following:
1. Start the engine and press theHUD dimmer control all the way
up by pressing the (+) button.
The brightness of the HUD
image is determined by the
light conditions in the direction
the vehicle is facing and where
you have the HUD dimmer
control set. If you are facing a
dark object or a heavily shaded
area, the HUD may anticipate
that you are entering a dark
area and may begin to dim.
It is possible for sunlight to enter
the HUD making it difficult to
see the image. The display
will return to normal when the
sunlight is no longer entering
the HUD. 2. Adjust the seat to a comfortable
driving position. If your seat
position changes, the HUD
may need to be re-adjusted.
3. Press the up or down arrows to center the HUD image in
your view.
The HUD image can only be
adjusted up and down, not
side-to-side.
4. Press the dimmer control downward until the HUD image
is no brighter than necessary.
To turn HUD off, press and hold the
(–) button until the HUD display
turns off.
If the sun comes out or it becomes
cloudy, the HUD brightness may
need to be adjusted again using
the dimmer control. Polarized
sunglasses could make the HUD
image harder to see. The HUD information can be
displayed in one of six languages
including English, Spanish, French,
German, Italian or Japanese.
The speedometer can be displayed
in either English or Metric units.
To change the language and unit
selections, see
“OPTION”under
“Operation and Displays” inDriver
Information Center (DIC) on
page 5‑25.
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.
