Eco A/C (For eAssist Vehicles) :
Press to cycle between the off, eco,
and comfort air conditioning modes.
The indicator will be lit green in eco,
amber in comfort, and turns off
when there is no A/C function. If the
fan is turned off, the A/C will not run.
The eco A/C setting balances fuel
economy and air conditioning
comfort. In warm weather
conditions, auto stops may occur
more frequently and the vehicle
interior may be warmer as
compared to the comfort air
conditioning. This setting allows
higher humidity inside the vehicle
and window fogging before the
engine restarts.
Pressing the
0
button during an
auto stop may restart the engine to
prevent window fogging. To reach
comfort levels quickly during an
auto stop, the engine will restart if
the air conditioner is off and AUTO
or A/C is selected.
If temperature controls are adjusted
cooler by more than 1° C (2° F)
during an auto stop, the engine will
restart to ensure that comfort is
reached.
@
(Recirculation) :
Press to turn
on recirculation. An indicator light
comes on. Air is recirculated to
quickly cool the inside of the
vehicle. It can also be used to help
reduce outside air and odors that
enter the vehicle. The air
conditioning compressor also comes
on when this mode is activated.
Auto Defog :
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.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
K
(Rear Window Defogger) :
Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The rear window defogger only
works when the ignition is in
ON/RUN. The defogger turns off if
the ignition is turned to ACC/
ACCESSORY or LOCK/OFF.
The rear window defogger can be
set to automatic operation. See
“
Climate and Air Quality
”
under
“
Vehicle Personalization
”
in the
owner manual. When auto rear
defog is selected, the rear window
defogger turns on automatically
when the interior temperature is cold
and the outside temperature is
about 4° C (40° F) and below. The
auto rear defogger turns off
automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
