AIR FLOW: Pressing the AIR FLOW button will display
and hold the current setting while in manual mode.
Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.
•
WINDSHIELD-FLOOR: This mode directs most of
the airflow to the windshield with some airflow to
the outboard outlets (for the side windows) and the
floor outlets.
•
MID: This mode directs airflow through the
instrument panel outlets.
•
FLOOR-MID: This mode directs airflow through
both the floor and the instrument panel outlets.
There is also a small amount of air directed to the
windshield and the outboard outlets (for the
side windows).
•
FLOOR: This mode directs most of the airflow to
the floor outlets with some directed to the outboard
outlets (for the side windows) and the windshield.
OFF: Press the OFF button once to turn off the
passenger climate control, if it has been activated.
Pressing the OFF button a second time will turn off the
main system. The outside temperature will be shown
on the display when the system is off.
VENT: Pressing the VENT button allows outside air to
flow through your vehicle without the air conditioning
compressor working. To turn off the VENT selection,
push the VENT button again.
Selecting the VENT and AUTO buttons at the same
time allows the system to control the airflow
automatically without using the air conditioning
compressor or the recirculation mode.
RECIRC (Recirculation): Press this button to limit the
amount of outside air coming into the vehicle. It can
be used to prevent outside air and odors from entering
your vehicle or to help heat or cool the air inside
your vehicle more quickly. Press this button to turn the
recirculation mode on or off. When the button is
pressed, an indicator light will come on. The recirculation
mode cannot be used with the FRONT defrost or
VENT mode.
On hot days, open the windows to let hot air escape;
then close them. This helps to reduce the time it takes
for your vehicle to cool down. It also helps the system
to operate more efficiently.
