Mirrors
Automatic Dimming Rearview
Mirror with Compass and
Temperature Display
If your vehicle is equipped with an automatic
mirror, it will, when on, automatically dim to the
proper level to minimize glare from lights behind
you after dark.
The mirror also includes a display in the upper
right corner of the mirror face. The compass
reading and the outside temperature will both
appear in the display at the same time. The dual
display can be turned on or off by briey
pressing the compass/temperature button.
O:This is the button for the automatic dimming
and compass/temperature functions.
Your vehicle may also have a Rear Vision
Camera. SeeRear Vision Camera on page 192
for more information.

Automatic Dimming Mirror Operation
To turn the automatic dimming feature on or
off, press and hold the compass/temperature
button until the indicator light located to the left of
the button turns on or off. This shows that the
automatic dimming feature is activated. Once the
mirror is turned off, it will remain off until it is
turned back on, or until the vehicle is restarted.
Temperature Display
The temperature can be displayed by pressing the
compass/temperature button. Pressing the
compass/temperature button once briey, will
toggle the temperature reading on and off. To
alternate the temperature reading between
Fahrenheit and Celsius, press and hold the
compass/temperature button for approximately
four seconds until the display blinks F and C. Press
and release the compass/temperature button to
toggle between the Fahrenheit and Celsius
readings. After approximately four seconds of
inactivity, the display will stop blinking and display
the last selection made.
If an abnormal reading is displayed, for an
extended period of time, please consult your
dealer. Under certain circumstances, a delay in
updating the temperature is normal.
Compass Operation
Press the compass/temperature button once
briey to turn the compass on or off.
Compass Calibration
The compass may need calibration if the
following occurs:
The compass does not display the correct
heading and the compass zone variance
is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push in the compass/temperature button for
approximately eight seconds or until CAL is
displayed.
The compass can only be calibrated by driving the
vehicle forward in circles at 5 mph (8 km/h) or less
until the display reads a direction. Do not attempt to
calibrate the compass by driving in reverse.
140

Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if you live
outside zone eight. Under certain circumstances,
as during a long distance cross-country trip, it
will be necessary to adjust for compass variance.
Compass variance is the difference between
earth’s magnetic north and true geographic north.
If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the compass/temperature
button for ve seconds until a zone number
appears in the display.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner.
Do not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter
the mirror housing.
141

Outside Power Mirrors
The controls are
located on the driver’s
door armrest.
Move the upper selector switch to the left or right
to choose the mirror to be adjusted, then press
the dots, located below the selector switch on the
four-way control pad, to adjust the direction of
each mirror.
The mirrors may also include a memory function
which works in conjunction with the memory seats.
SeeMemory Seat and Mirrors on page 10for
more information.
Power Folding Mirrors
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. The mirror will adjust as it
folds in and will reposition itself once it is 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, the mirrors need to
be reset. See “Resetting the Power Folding
Mirrors” next.
Resetting the Power Folding Mirrors
The power folding mirrors will need to be reset if:
They are accidently 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 folding mirrors, fold and unfold
them at least three times using the mirror controls.
This will reset them to their normal detent position.
142

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.
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be
seen from the driver’s seat. It makes things in the
mirror appear farther away than they really are.
Outside Heated Mirrors
If the vehicle has
heated mirrors, the
button to turn this
function on or off is
located on the climate
control panel.
Press this button to warm the driver’s and
passenger’s outside rearview mirrors to help clear
them of ice, snow, and condensation.
With a rear window defogger, the heated mirrors
will come on when this button is pressed. See
“Rear Window Defogger” underDual Automatic
Climate Control System on page 197for more
information.

Outside Automatic Dimming Mirror
with Curb View Assist
If the vehicle has this feature, the driver’s outside
mirror adjusts for the glare of the headlamps behind
you. SeeAutomatic Dimming Rearview Mirror with
Compass and Temperature Display on page 139.
The vehicle’s outside mirrors can also perform a
curb view assist mirror function. This causes
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
viewing 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 enabled/disabled through the
Driver Information Center. SeeDIC Vehicle
Customization on page 234for more information.

{CAUTION:
The Rear Vision Camera (RVC)
system does not replace driver vision.
RVC does not:
Detect objects that are outside the
camera’s eld of view, below the
bumper, or underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only looking at
the rear vision camera screen, or use the
screen during longer, higher speed
backing maneuvers or where there could
be cross-traffic. Your judged distances
using the screen will differ from actual
distances.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the RVC system,
always check carefully before backing up
by checking behind your vehicle.
