GMC 2013 Acadia/Acadia Denali Owner's Manual page 144

5-30 Instruments and Controls
Metric
Format Three: This display
includes all the information in
Format One along with a circular
tachometer, but without outside air
temperature.
All formats will show the turn-by-turn
navigation information and provide
details about the next driving
maneuver to be made. When you
near your destination, the HUD will
display a distance bar that will fill in
the closer you get to your
destination. All navigation
information is provided to the HUD
by the navigation radio, if the
vehicle has one.
The HUD image displayed on the
windshield will automatically dim
and brighten to compensate for
outside lighting.
The HUD image can temporarily
light up depending on the angle and
position of the sunlight on the HUD
display. This is normal and will
change when the angle of the
sunlight on the HUD display
changes.
Polarized sunglasses could make
the HUD image harder to see.
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
If You Cannot See the HUD
Image When the Ignition Is On
Is anything covering the
HUD lens?
Is the HUD dimmer setting bright
enough?
Is the HUD image adjusted to
the proper height?
Are you wearing polarized
sunglasses?
If the HUD Image Is Not Clear
Is the HUD image too bright?
Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer.
Keep in mind that the windshield is
part of the HUD system.
