GMC 2007 Sierra - Manual (Page 187)

Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors
if the following occurs:
• They are accidentally manually folded/
unfolded.
• The mirrors will not stay in the unfolded
position.
• The mirrors shake and flutter at normal driving
speeds.
To reset the power foldaway mirrors, fold and
unfold them at least three times using the mirror
controls. This will reset them to their normal
position.
Outside Automatic Dimming Mirror
If your vehicle is equipped with this feature,
the driver’s outside mirror will adjust for the glare
of headlamps behind you. This feature is
controlled by the on and off settings found on the
electrochromic inside mirror.
Outside Curb View Assist Mirrors
If the vehicle has the memory package, the outside
mirrors are able to perform the curb view assist
mirror function. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a
preselected position when the vehicle is in
REVERSE (R). This feature may be useful in
allowing the driver to view the curb when parallel
parking. When the vehicle is shifted out of
REVERSE (R) and a short delay has occurred,
the passenger’s and/or driver’s mirror will return to
its original position.
To change the preselected tilt position, adjust the
mirrors to the desired position while the vehicle
is in REVERSE (R). When the vehicle is shifted
out of REVERSE (R), this new position is saved in
memory as the tilt position.
This feature can be turned on or off through the
Driver Information Center (DIC). See Driver
Information Center (DIC) on page 265 for more
information.
