To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the map.
2. Press and hold the on/off button for six seconds.
Release the button when ZONE is displayed. The
number shown is the current zone number.
3. Scroll through the zone numbers that appear in
the compass/temperature window on the mirror by
pressing the on/off button. Once you nd your zone
number, release the button. After about four
seconds, the mirror will return to the compass
display, and the new zone number will be set.Automatic Dimming Rearview
Mirror with Compass and
Temperature Display
If the 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
brie y pressing either the TEMP or the COMP button.
Temperature Display
The temperature can be displayed by pressing the TEMP
button. Pressing the TEMP button once brie y, will toggle
the temperature reading on and off. To alternate the
temperature reading between Fahrenheit and Celsius,
press and hold the TEMP button for approximately
four seconds until the display blinks F and C. Press
and release the TEMP 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.

Automatic Dimming Mirror Operation
The time period you need to press and hold the TEMP
button to turn the automatic dimming feature on or off is
approximately eight seconds. The indicator light to the left
of the TEMP button will still turn on or off to show you
when 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.
Compass Operation
Press the COMP button once brie y 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.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
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
in the COMP button for approximately eight seconds
or until CAL is displayed.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.

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 COMP button for ve seconds
until a zone number appears in the display.
3. Press the COMP 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.

Passenger Airbag Indicator
The mirror may be equipped with a passenger airbag
indicator on the mirror glass, just above the buttons.
If the vehicle has this feature the mirror will display the
word ON, or an airbag symbol in Canada, when the
passenger airbag is enabled. For more information see
Passenger Sensing System on page 1-81
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
Adjust your outside mirrors so you can just see the side of
your vehicle and have a clear view of objects behind you.
The mirrors can be folded in to enter narrow areas.
The use of hood-mounted air de ectors and add-on
convex mirror attachments may adversely affect mirror
performance.
Outside Camper-Type Mirrors
If your vehicle is equipped with this style camper-type
mirrors, they can be adjusted so you can have a clear
view of the objects behind you.
Pull out the mirror head to extend it for better visibility
when towing a trailer.
