Outside West Coast-Type Mirrors
If your vehicle is equipped with these mirrors, they
can be adjusted so you can have a clear view
of objects behind you.
A. Outer Mirror Frame
B. Mirror Head
C. Nut
The mirrors can be adjusted by turning the mirror
head (B) and moving the outer mirror frame (A)
backward or forward. You can also loosen
the nut (C) on the top and bottom of the outer
mirror frame to tilt the mirror head.
Outside Power Mirrors
If your vehicle is
equipped with power
outside mirrors,
the controls are located
on the driver’s door
armrest.
Move the selector switch located above the control
pad 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 can be manually folded inward to
prevent damage when going through an automatic
car wash. To fold, push the mirror toward the
vehicle. To return the mirror to its original position,
push outward. Be sure to return both mirrors to
their original unfolded position before driving.
185

Outside Power Foldaway Mirrors
If your vehicle is
equipped with this
feature, the controls are
located on the driver’s
door armrest.
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.
SeeMemory Seat and Mirrors on page 12for 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 utter 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.
186

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.
