Buick 2010 Lacrosse - Manual (Page 118)

4-32 Instruments and Controls
All navigation information is
provided to the HUD by the
navigation radio or OnStar
®
service, for vehicles that have
these features.
The HUD image displayed on the
windshield will automatically dim
and brighten to compensate for
outside lighting. However, the HUD
brightness control can still be
adjusted as needed.
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?
. Still no HUD image? Check the
fuse in the instrument panel fuse
block. See Instrument Panel
Fuse Block on page 9‑44.
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/retailer.
Keep in mind that the windshield is
part of the HUD system.
