Mirrors
Inside Day/Night Rearview Mirror
When you are sitting in a comfortable driving position,
adjust the mirror so you can see clearly behind your
vehicle. Grip the mirror in the center to move it up or
down and side to side. The day/night adjustment allows
you to adjust the mirror to avoid glare from the lights
behind you. Pull the tab toward you for night use; push
it away from you for daytime use.
Electrochromic Day/Night Rearview Mirror
(Option)
Your vehicle may have an automatic electrochromic
day/night rearview mirror.
When this feature is turned on, the mirror automatically
changes to reduce glare from headlamps behind you. A
photocell on the mirror senses when it is becoming dark
outside. Another photocell built into the mirror face
senses when headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced.

Mirror Operation
To turn on the automatic dimming feature, press
AUTO. To turn off automatic dimming, press OFF.
The green indicator light will be illuminated when this
feature is active.
Time Delay
The automatic mirror has a time delay feature which
prevents unnecessary switching from the night back to
the day position. This delay prevents rapid changing of
the mirror as you drive under lights and through traffic.
Cleaning the Photocells
Use a cotton swab and glass cleaner to clean the
photocells when necessary.
Electrochromic Day/Night Rearview Mirror
with Compass (Option)
Your vehicle may have an electrochromic inside
rearview mirror with a compass.
When set in the MIRROR position, this mirror
automatically changes to reduce glare from headlamps
behind you. A time delay feature prevents rapid
changing from the day to night positions while driving
under lights and through traffic.
The mirror also includes an eight
-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.
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. Use a cotton swab and
glass cleaner to clean the photocells when necessary.

2-48
Mirror Operation
The right side of the button located at the bottom of the
mirror turns the electrochromic mirror on and off. To
turn on the automatic dimming feature, press MIRROR.
To turn off automatic dimming, press MIRROR again.
The green indicator light will be illuminated when this
feature is active.
Compass Operation
Press the COMPASS button once to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for
approximately two seconds. After two seconds, the
mirror will display the compass heading.If, after two seconds, the display does not show a
compass heading (ªNº for North, for example), there
may be a strong magnetic field interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder or a
similar magnetic item.
Compass Calibration
If the letter ªCº should ever appear in the compass
window, the mirror may need calibration.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display reads a direction, or

Drive the vehicle on your everyday routine.
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.

yellowblue
2-49
To adjust for compass variance:
1. Press and hold the COMPASS button located at the
bottom of the mirror until a zone number appears in
the display.
2. Find your current location and variance zone number
on the following zone map.3. Press the COMPASS button on the bottom of the
mirror until the new zone number appears in the
display. After you stop pressing the button, the
display will show a compass direction within a few
seconds. (This is the automatic calibration mode.
Drive in a circle to calibrate the mirror. See
ªCompass Calibrationº explained previously.)

2-50 Power Remote Control Mirror
Your vehicle has an electric mirror control located on
the driver's door armrest.
Move the inner switch to the right (R) or left (L) to
choose either the driver's or passenger's side mirror.
Press any of the four arrow buttons to move the mirror
in the direction desired.Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle. When the
inner switch is in the center position, the mirrors cannot
be adjusted.
Your vehicle may be equipped with the memory
function. These mirror positions, along with the driver's
seat cushion position, can be stored into memory. See
ªMemory Seats and Mirrorsº in the Index.
Parallel Park Assist Mirror (Option)
The passenger's outside rearview mirror also includes a
tilt
-down feature that operates when the shift lever is in
REVERSE (R). This feature assists the driver with
improved rear obstacle detection.
To enable this feature, move the power remote mirror
switch to the left (L) or center position. Move the switch
to the right (R) to turn this feature off.

yellowblue
2-51 Convex Outside Mirror
Your passenger's side mirror is convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
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.
Heated Outside Rearview Mirror
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's outside
rearview mirrors to help clear them of ice and snow. See
ªRear Window Defoggerº in the Index.
Automatic Dimming Outside Rearview
Mirror (Option)
If you have this feature, the driver's side outside mirror
will adjust for the glare of headlamps behind you. This
feature is controlled by the on and off settings on the
automatic electrochromic day/night rearview mirror. See
ªAutomatic Electrochromic Day/Night Rearview
Mirrorº earlier in this section.
