to choose the mirror you want to adjust; then
press the dots located on the four-way control pad

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

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

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 utter 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). SeeDriver
Information Center (DIC) on page 265for more
information.
187

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply into
the right lane, you could hit a vehicle on
your right. Check your inside mirror or
glance over your shoulder before
changing lanes.
Your passenger’s side mirror is convex. A convex
mirror’s surface is curved so you can see more
from the driver’s seat.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
helps clear them of condensation, snow, and ice.
The mirror heat is controlled by pressing the
outside mirror button, if the vehicle has a sliding
rear window, or the rear window defogger
button. See “Rear Window Defogger” underDual
Automatic Climate Control System on page 235
for further information.
The mirror heat will turn off about 10 minutes after
the button is pressed. Press the button again if
additional warming time is needed.
