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
circles at 5 mph (8 km/h) or less until the display
reads a direction.

Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
For more information, seePassenger Sensing System
on page 1-78.
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.
Automatic Dimming Rearview
Mirror with Compass and
Temperature Display
If your vehicle is equipped with an automatic mirror, it
will 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 either the TEMP or the COMP button.
Temperature Display
The temperature can be displayed by pressing the
TEMP button. Pressing the TEMP button once briey,
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 see 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 briey 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 ve 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.
2-59

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 Air Bag Indicator
Your mirror may be equipped with a passenger air bag
indicator on the mirror glass, just above the buttons.
For more information seePassenger Sensing System
on page 1-78.
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 deectors and add-on
convex mirror attachments may adversely affect
mirror performance.

Resetting the Power Foldaway Mirrors
You will need to reset the power foldaway mirrors if the
following occurs:
They are accidentally 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 foldaway mirrors, fold and unfold
them at least three times using the mirror controls.
This will reset them to their normal position.
Outside Automatic Dimming Mirror
If your vehicle is equipped with this feature, the
driver’s outside mirror will adjust for the glare of
headlamps behind you. This feature is controlled by the
on and off settings found on the electrochromic
mirror. SeeAutomatic Dimming Rearview Mirror with
Compass and Temperature Display on page 2-58.
Outside Curb View Assist Mirrors
If your vehicle has the optional memory package
you may have this feature.
The vehicle’s mirrors are capable of performing the curb
view assist mirror function. This feature will cause 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 allowing you to view the curb
when you are 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.
You may be able to enable/disable this feature through
the Driver Information Center. SeeDriver Information
Center (DIC) on page 3-53.
