Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
See your dealer to match additional transmitters to
your vehicle.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.

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

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 and the
comfort setting. 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 WINDSHIELD. 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.

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 previously chosen comfort setting. The
outside temperature will show on the display when the
system is set to OFF.The ventilation system always allows fresh air to flow
through the interior when the vehicle is moving even
with the system in the OFF mode.
VENT: The VENT button allows outside air to flow
through your vehicle without the air conditioning
compressor working. Selecting VENT and the AUTO
button at the same time allows the system to control
automatically without the use of the air conditioning
compressor or the use of the RECIRC mode. To turn off
the VENT selection, push the VENT button again.
RECIRC: When RECIRC is selected, the system will
limit the amount of outside air entering your vehicle.
This is helpful when you are trying to cool the interior
of the vehicle quickly or limit the amount of outside air
entering your vehicle for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC until the ignition is
turned off, then the system will return to the previously
selected mode. RECIRC can be selected in all manual
airflow modes except FRONT defrost. RECIRC cannot
be selected with the VENT button.
Operating RECIRC in cold temperature or under high
humidity conditions may cause moisture to form on the
inside of the windshield. If this condition occurs,
deselect the RECIRC button.
