Temperature and Compass Display
Press the on/off button, located to the far left, briey to
turn the compass/temperature display on or off.
If the display reads CAL, you will need to calibrate the
compass. For more information on calibration,
see below.
To adjust between Fahrenheit and Celsius do the
following:
1. Press and hold the on/off button for approximately
four seconds until either a ashing F or C appears.
2. Press the button again to change the display to the
desired unit of measurement. After approximately
four seconds of inactivity, the new unit will be locked
in and the compass/temperature display will return.
If an abnormal temperature reading is displayed for an
extended period of time, please consult your dealer.
Under certain circumstances, a delay in updating
the temperature is normal.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned
on automatically each time the ignition is started. To
operate the automatic dimming mirror, do the following:
1. Make sure the green indicator light, located to the left
of the on/off button, is lit. If it’s not, press and hold the
on/off button for approximately six seconds until the
green light comes on, indicating that the mirror is in
automatic dimming mode.
2. Turn off the automatic dimming mirror function by
pressing and holding the on/off button for
approximately six seconds, until the green indicator
light turns off.
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 of 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 your current location and variance zone
number on the following zone map.
2. Press and hold the on/off button until a Z and a
zone number appear in the display. The compass
is now in zone mode.
3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the compass/temperature display will return.
4. Calibrate the compass as described below.Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately ve seconds, the display does
not show a compass heading (N for North, for
example), there may be a strong magnetic eld
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item.
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
the on/off button for approximately 12 seconds or
until CAL is displayed.
The compass can be calibrated by driving the vehicle in

word ON, or an airbag symbol in Canada, when the
passenger airbag is enabled. For more information see
Passenger Sensing System on page 1-67
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 Manual Mirrors
If the vehicle has the manual outside mirrors, adjust
each outside mirror so that a little of the vehicle and the
area behind it can be seen while sitting in a comfortable,
driving position.
Both mirrors can be manually folded inward by pulling
them towards the vehicle. Push the mirrors away
from the vehicle, to the normal position, before driving.
Outside Power Mirrors
Your vehicle may have this feature. The power mirror
control is located on the driver’s door.
Turn the knob counterclockwise or clockwise to adjust
the driver’s or passenger’s mirror so that you can see a
little of the side of your vehicle. After adjusting the
position of the mirrors, turn the knob to the center
position so that the mirrors cannot move.
If the travel position in any direction of the mirror is
reached, it will enter a ratcheting mode. This action is
harmless. It is a warning that the mirror can go no
further. To stop this action, back the mirror up by moving
the knob in the opposite direction.
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.

Outside Curb View Assist Mirror
If the vehicle has this feature, the passenger’s outside
mirror will adjust to a preset tilt position while the vehicle
is in REVERSE (R) gear. Curb view assist may be
useful when you are parallel parking. The mirror
will return to normal position when the vehicle is shifted
out of REVERSE (R) gear. Automatic mirror movement
in either direction will follow a short delay.
You may be able to turn this feature on or off through
the Driver Information Center (DIC). SeeDIC Vehicle
Customization on page 3-60.
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 or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
The passenger’s outside mirror is convex. A convex
mirror’s surface is curved so more can be seen from the
driver’s seat.
Outside Heated Mirrors
Your vehicle may have this feature. When you operate
the rear window defogger, the defogger also warms
the heated driver’s and passenger’s outside rearview
mirrors to help clear them of ice, snow and
condensation.
