GMC 2008 Acadia - Manual (Page 163)

The HUD information can be displayed in one of
three languages, English, French, or Spanish. The
speedometer reading and other numerical values
can be displayed in either English or metric units.
The language selection and the units of measurement
are changed through the trip computer in the
Driver Information Center (DIC). See DIC Vehicle
Customization (With DIC Buttons) on page 3-75.
The HUD information appears as an image focused
out toward the front of the vehicle.
When the ignition key is turned to RUN, the HUD will
display an introductory message for a short time,
until the HUD is ready.
The following indicator lights come on the instrument
panel when activated and will also appear on the HUD:
• Turn Signal Indicators
• High-Beam Indicator Symbol
The HUD will temporarily display CHECK GAGES and
ICE POSSIBLE when there are messages on the
DIC trip computer.
The HUD will also display the following messages on
vehicles with these systems, when they are active:
• TRACTION CONTROL ACTIVE
• STABILITRAK ACTIVE
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.
When the HUD is on, the speedometer reading will
continually be displayed. The current radio station
or CD track number will display for a short period of
time after the radio or CD track status changes.
This will happen whenever radio information is changed.
The speedometer size will be reduced when radio,
CD information, warnings, or turn-by-turn navigation
information are displayed on the HUD.
