The mirror can be calibrated by driving the vehicle
in circles at 5 mph (8 km/h) or less until the
display reads a direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button
untilaCisshown in the compass display.
Compass Variance
The zone is set to 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 do the following:
1. Find the current location and variance
zone number on the following zone map.2. Press and hold the on/off button until a zone
number appears in the display.
3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop
pressing the button and the mirror will return
to normal operation. If C appears in the
compass window, the compass may need
calibration. SeeCompass Calibration
listed previously.

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.
Outside Power Heated Mirrors
The power mirror
control is on the driver’s
door armrest and
controls the driver’s
side and passenger’s
side mirrors.
Move the selector switch left or right to choose the
driver’s side or passenger’s side mirror. Use the
arrows located on the control pad to adjustthe position of each mirror. Adjust each mirror so
you can see the side of your vehicle and the
area behind your vehicle. Return the selector
switch to the center position when nished
adjusting. This will prevent unwanted mirror
movement in case the control pad is accidentally
bumped while driving.
The preferred mirror positions can be stored with
the memory option. SeeMemory Seat, Mirrors
and Steering Wheel on page 169.
The mirrors can be manually folded inward to
prevent damage when going through car washes
or con ned spaces. 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.
When the rear window defogger is turned on, both
outside rear view mirrors are heated to help
clear them of ice, snow, or condensation. See
“Rear Window Defogger” underDual Climate
Control System on page 230.

Outside Automatic Dimming Mirror
The driver’s side mirror will adjust for the glare
of headlamps behind you. This feature is controlled
by the on and off settings on the automatic
dimming rearview mirror.
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. This mirror does not
have a dimming feature.
Outside Parallel Park Assist Mirror
This feature assists the driver by improving
rear obstacle detection and is useful in viewing the
curb when parallel parking.
Press the left or right mirror symbol on the
selector control to choose the driver or passenger
outside mirror. When the vehicle is shifted into
REVERSE (R), the selected mirror will tilt to
a factory programmed position. If further mirror
adjustment is needed press the arrows located on
the outside mirror control pad. If the outside
mirror selector switch is in the middle position,
neither outside mirror will move.
When the vehicle is shifted out of REVERSE (R),
and a ve-second delay has occurred, the
mirror will return to its original position. The delay
prevents movement of the mirror if multiple
gear transitions REVERSE (R) to DRIVE (D) to
REVERSE (R) occur during a parallel parking
maneuver.
