Automatic Dimming Mirror Operation
O
:Press this button to turn the automatic dimming
feature on or off. The indicator light to the left of
the button will turn on to indicate when the feature is on.
Once the mirror is turned off, it will remain off until it
is turned back on, or until the vehicle is restarted.
Temperature Display
The temperature can be displayed by pressing
the compass/temperature button. Pressing the
compass/temperature button once briey, will toggle
the temperature reading on and off. To alternate
the temperature reading between Fahrenheit and
Celsius, press and hold the compass/temperature
button for approximately four seconds until the
display blinks F and C. Press and release the
compass/temperature 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/retailer.
Under certain circumstances, a delay in updating the
temperature is normal.
Compass Operation
Press the compass/temperature button once briey to
turn the compass on or off.
Compass Calibration
The compass may need calibration if the following occurs:
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 compass/temperature button for approximately
eight seconds or until CAL is displayed.
The compass can only be calibrated by driving the
vehicle forward in circles at 5 mph (8 km/h) or less until
the display reads a direction. Do not attempt to
calibrate the compass by driving in reverse.

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 compass/temperature button for
ve seconds until a zone number appears in the
display.
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 Automatic Dimming Mirror
If the vehicle has this feature, the driver’s outside mirror
adjusts for the glare of the headlamps behind you.
SeeAutomatic Dimming Rearview Mirror with Compass
and Temperature Display on page 2-45.
Park Tilt Mirrors
The vehicle’s outside mirrors can also perform a park tilt
function. This causes 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
viewing the curb when 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.
This feature can be enabled/disabled through the Driver
Information Center. SeeDIC Vehicle Customization
(With DIC Buttons) on page 3-63for more information.
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 side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver seat. It also makes things, like other vehicles,
look farther away than they really are.
Outside Heated Mirrors
The vehicle may have outside heated mirrors which
help clear them of condensation, snow, and ice.
When the rear window defogger button is pressed, the
heated mirrors are also turned on. See “Rear Window
Defogger” underDual Automatic Climate Control System
on page 3-22for more information.

Object Detection Systems
Rear Vision Camera
Your vehicle may be equipped with a rear vision camera
system. Read this entire section before using the
camera system.
The rear vision camera system is designed to help
the driver when backing up by displaying a view of the
area behind the vehicle. When the driver shifts the
vehicle into REVERSE (R), the video screen will
automatically slide out from the rear view mirror.
Once the driver shifts out of REVERSE (R), the video
screen will slide back into the rear view mirror after
a delay.
If your vehicle does not have a rearview mirror slide-out
video screen, your vehicle may have a navigation
radio system. See the Navigation System manual for
more information on the rear vision camera display
video screen.

For more information on the automatic dimming,
compass, and temperature features of the mirror,
seeAutomatic Dimming Rearview Mirror with
Compass and Temperature Display on page 2-45.{CAUTION:
The Rear Vision Camera (RVC) system does
not replace driver vision. RVC does not:
Detect objects that are outside the
camera’s eld of view, below the bumper,
or underneath the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
Do not back the vehicle by only looking at
the rear vision camera screen, or use the
screen during longer, higher speed backing
maneuvers or where there could be
cross-traffic. Your judged distances using the
screen will differ from actual distances.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even though
the vehicle has the RVC system, always check
carefully before backing up by checking
behind and around your vehicle.
