Buick 2010 Lacrosse Owner's Manual page 121

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.
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.
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?
Still no HUD image? Check the
fuse in the instrument panel fuse
block. See
Is the HUD image too bright?
Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer/retailer.
Keep in mind that the windshield is
part of the HUD system.
Messages are displayed on the DIC
to notify the driver that the status of
the vehicle has changed and that
some action may be needed by the
driver to correct the condition.
Multiple messages may appear one
after another.
Some messages may not require
immediate action, but you can press
SET to acknowledge that you
received the messages and to clear
them from the display. Some
messages cannot be cleared from
.
the DIC display because they are
more urgent. These messages
require action before they can be
cleared. You should take any
messages that appear on the
display seriously and remember that
clearing the messages will only
make the messages disappear, not
correct the problem. You will find the
possible messages that can be
displayed and some information
about them grouped by subject in
the following information.
