Buick 2010 Lacrosse - Manual (Page 120)

4-32 Instruments and Controls
Format Two: This display includes
the information in Format One
without the transmission
information, the outside air
temperature, and compass heading. Format Three: This display
includes all the information in
Format One along with a circular
tachometer, but without outside air
temperature and compass heading.
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
empty the closer you get to your
destination. 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.
