Cadillac 2007 XLR - Manual (Page 171)

Reading Lamps
Your inside rearview mirror includes two reading
lamps. The lamps will go on when a door is
opened. When the doors are closed, each lamp
can be turned on individually by pressing the
button for that lamp.
Battery Run-Down Protection
Your vehicle has a feature to help prevent the
battery from being drained, in case the underhood
lamp, vanity mirror lamps, cargo lamps, reading
lamps, console, or glove box lamps are
accidentally left on, or something is left plugged
into the accessory power outlet or cigarette lighter.
If any of the accessory lamps are left on, they
will automatically time-out after about 20 minutes.
To reset the battery protection, all of the above
lamps must be turned off or the ignition must be in
the Acc position.
Head-Up Display (HUD)
{ CAUTION:
If the HUD image is too bright, or too high
in your field of view, it may take you more
time to see things you need to see when it
is dark outside. Be sure to keep the HUD
image dim and placed low in your field
of view.
The Head-Up Display (HUD) allows you to see
some of the driver information that appears
on your instrument panel cluster.
The information may be displayed in English or
metric units and appears as an image focused out
toward the front of your vehicle. To change
from English to metric units, see Driver Information
Center (DIC) on page 203.
