control and the direction of the
airflow is controlled manually. Press
AUTO to return to automatic
operation.
To change the current mode, select
one or more of the following:
6:Air is directed to the floor
outlets, with some air to the
windshield and side windows.
Y: Air is directed to the instrument
panel outlets.
X: Clears the windows of fog or
moisture. Air is directed to the
windshield.
1MAX : Air is directed to the
windshield, the fan runs at a higher
speed, and the temperature of the
air is increased if not already at
maximum. This mode overrides the
previous mode selected and clears
fog or frost from the windshield
more quickly. When the control is
pressed again, the system returns
to the previous mode setting and
fan speed. For best results, clear all snow and
ice from the windshield before
defrosting.
For eAssist vehicles that have the
auto defog feature, Auto Stops can
occur in defrost mode. In this mode,
the Auto Stops are shorter and less
frequent than other air delivery
modes to prevent window fogging.
A/C :
Touch A/C on the climate
control display to cycle between the
MAX, ECO, and OFF modes. The
MAX, ECO, or OFF indicator will
appear on the display. If the fan is
turned off, the air conditioner will not
run and the indicator light will
turn off.
Touch AUTO to return to automatic
operation and the air conditioner
runs automatically as needed. The
A/C will return to ECO A/C
operation.
For MAX A/C, touch A/C.
For ECO A/C, touch A/C again. This
setting balances fuel economy and
air conditioning comfort. This setting allows higher humidity inside the
vehicle, and window fogging may
occur before the engine restarts.
@:
Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or to reduce the
entry of outside air and odors.
If selected during cool or cold
weather, the windshield and
windows may fog. Turn off
recirculation to help clear the
windshield and windows.
Auto Defog : If equipped, the
climate control system may have a
sensor to automatically detect high
humidity inside the vehicle. When
high humidity is detected, the
climate control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation. For eAssist vehicles,
there may be shorter and less
frequent Auto Stops when auto
defog is in use.
