Electrochromic Day/Night Rearview Mirror
(If Equipped)
Your vehicle may have an automatic electrochromic
day/night rearview mirror.
When this feature is turned on, the mirror automatically
changes to reduce glare from headlamps behind you. A
photocell on the mirror senses when it is becoming dark
outside. Another photocell built into the mirror face
senses when headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare is reduced.

Note to Canadian Owners: During programming, the
hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the Universal Transmitter. Release both
buttons when the indicator light on the Universal
Transmitter begins to flash rapidly.
Operating the Universal Transmitter
Press and release the appropriate button on the Universal
Transmitter. The indicator light comes on while the
signal is being transmitted.
If the hand
-held transmitter appears to program the
Universal Transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a ªrolling
codeº system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.To determine if you have this system, press the button
on the Universal Transmitter that you have programmed
already. If the indicator light on the Universal
Transmitter flashes rapidly for one or two seconds and
then turns solid, the garage door opener has a rolling
code system. In a rolling code system, the garage
door motor head unit must be trained to the
Universal Transmitter.
ªRolling Codeº Programming
(If Equipped)
If you have not previously programmed the hand-held
transmitter to the Universal Transmitter, see
ªProgramming the Universal Transmitterº listed
previously. If you have completed this programming
already, you now need to train the garage door opener
motor head unit to recognize the Universal Transmitter.
Refer to your garage door opener owner's manual for
the proper transmitter training procedure for your garage
door opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color of the
button may vary by garage door opener brand. If you
have difficulty finding the training button, refer to
your garage door opener owner's manual.

Comfort Controls
This section tells you how to operate your comfort
controls. Your comfort control system uses
ozone
-friendly R-134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation in your vehicle. Your vehicle also has a
flow
-through ventilation system described later in
this section.
Personal Choice Comfort Controls
(If Equipped)
This feature allows two different drivers to store and
recall their own climate control settings for temperature,
air delivery mode, fan and passenger climate control
(on/off) status. The Personal Choice settings recalled are
determined by the transmitter used to enter the vehicle.
After the UNLOCK button of a remote keyless entry
transmitter is pressed, and the ignition is in RUN, the
climate control will adjust to the last settings of the
identified driver. The settings can also be changed by
pressing one of the MEMORY buttons (1 or 2) located
on the driver's door, until you hear two beeps. When
adjustments are made, the new settings are automatically
saved for the driver.
Dual Automatic ComforTemp
Climate Control
Your vehicle has the dual automatic comfortemp climate
control system. The following information tells you how
it works.
You will hear a beep each time a button is pushed and a
small light on the button will indicate which buttons are
active. The lights are on all buttons except TEMP, FAN
and AIR FLOW. The display will show fan speed,
comfort level setting and airflow direction for a few
seconds whenever any button, except for the rear defog,
is pushed, and then it will display the outside
temperature. The outside temperature reading is most
accurate when the vehicle is moving.
During stops, when driving slow, or when the engine is
first started after a short trip, the outside temperature
reading can be affected by road or engine heat. Also,
starting the engine within a short time after the vehicle
has been running will affect the reading. To ensure
proper automatic climate control operation, the
outside temperature display may not update as quickly
as expected.

Automatic Operation
Press the AUTO button when you want the system to
automatically adjust to changes in the temperature.
When the system is set for automatic operation, air will
come from the floor, middle or windshield outlets
depending on the temperature inside the vehicle, the
outside temperature and sun load. Fan speed will vary as
the system gets to and maintains the comfort setting you
have selected through the use of the TEMP button.
To find your comfort setting, start with the system
in AUTO mode and the TEMP button adjusted to a
display of 75
F (24
C), give the vehicle about
20 minutes to stabilize, and adjust your comfort
setting if necessary, by using the TEMP button. The
display will show the comfort setting, fan speed and
airflow direction for a few seconds, and then it will
display the outside temperature.
In cold weather, the system will delay turning the fan on
high, to avoid blowing cold air. The length of the delay
depends on the engine coolant temperature and the
outside temperature. Pushing the FAN, AIR FLOW or
FRONT buttons will override this delay, turn off the
AUTO setting and change the fan speed.Manual Operation
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the direction
of the airflow. The airflow choices available are
FLOOR, FLOOR
-MID, MID and
WINDSHIELD
-FLOOR. If the system is set for AUTO,
pressing the AIR FLOW button will display the current
airflow direction, the comfort setting and the fan speed.
Press the AIR FLOW up or down button again to
change the direction of the airflow.
If the AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the mid
-position. If the AIR FLOW down button
is selected while in the FRONT defrost mode, the
system will direct the air toward the FLOOR, and the
FRONT defrost mode will cancel. Notice the arrows in
the display.
OFF: If the passenger comfort control is turned on, it can
be turned off by pressing the OFF button once. Pressing
the OFF button a second time will turn off the main
system. Turning off the main system causes the fan to turn
off and the airflow to be directed to the floor. The system
will still try to keep the interior of the vehicle at the
previous chosen comfort setting. The outside temperature
will show on the display when the system is off.
