Outside Automatic Dimming Mirror - GMC Sierra 2005 Owner's Manual

Move the upper selector switch to the left or right to
choose the mirror you want to adjust; then press
the dots located on the four-way control pad to adjust
the mirror.
The mirrors may also include a memory function which
works together with the memory seats. See "Memory
Seats" under Memory Seat on page 2-78 for more
information.
To fold or unfold the mirrors, move the selector
switch, located above the mirror control, to the middle
position. The mirror control will illuminate. Press the
right or left side of the mirror control to fold or unfold
the mirrors. You may notice the mirror glass adjust
as the mirrors fold in; this is normal. The mirror glass
will reposition itself once the mirrors are unfolded.
If the mirrors are accidentally folded/unfolded manually,
they may shake or flutter at normal driving speeds
and may not stay in the unfolded position. If this
happens, you will need to reset the mirrors. See
"Resetting the Power Foldaway Mirrors" next.
