Adjust the air flow direction of the ventila-
tors by moving the center knob (up/down,
left/right) until the desired position is
achieved.
WARNING
.The air conditioner cooling function
operates only when the engine is
running.
. Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. On
hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or
possibly fatal injuries to people or
animals.
. Do not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
. Do not adjust the heating and air
conditioning controls while driving so
that full attention may be given to
vehicle operation.
Start the engine and operate the automatic
climate control system.
NOTE:
. Odors from inside and outside the
vehicle can build up in the air conditioner
unit. Odor can enter the passenger compartment through the ventilators.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.

. When the “
” front defroster button is
pushed, the air conditioner will automa-
tically be turned on at outside tempera-
tures above 23°F (−5°C) to defog the
windshield, and the air recirculate mode
will automatically be turned off.
Outside air is drawn into the passenger
compartment to improve the defogging
performance.
Manual operation
Fan speed control:
Push the fan speed increase “
”or
decrease “” buttons to manually control
the fan speed.

” button when you
want the air conditioner to work quickly.
To turn the system off, push the upper vent
“
” button to turn the indicator light off.
Advanced Climate Control System
(if so equipped)
The Advanced Climate Control System
keeps the air inside of the vehicle clean,
using the ion control and the automatic air
intake control with exhaust gas detecting
sensor.
JVH1780X
Ion control:
This unit generates highly concentrated
Plasmacluster
®ions into the air blown from
the ventilators and reduces odor absorbed
into the interior trim.
The high-density Plasmacluster
®ions gen-
erated in the air conditioner’s air stream not
only suppress airborne bacteria and reduce
the adherence of odors to the interior trim,
but also have a proven skin moisture pre-
serving effect.
When the air conditioner is turned on, the
system generates Plasmacluster
®ions auto-
matically.
The amount of Plasmacluster
®ions in-
creases according to the amount of air flow.

Exhaust gas/outside odor detection sensor:
This vehicle is equipped with an exhaust gas
detection sensor. When the automatic in-
take air control is ON, the sensor detects
industry odors such as pulp or chemicals, and
exhaust gas such as gasoline or diesel. When
such odors or gas are detected, the system
automatically changes from the outside air
circulation mode to the recirculation mode.
When the auto-recirculation button is
pushed under the following conditions, the
indicator light on the “
” button will
illuminate and the exhaust gas detection
sensor will turn on.
. The air flow control is not in the front
defroster mode (the indicator light on the
“
” front defroster button is turned
off).
. The outside temperature is about 32°F
(0°C) or more.
When the automatic intake air control is ON,
for the first 5 minutes, the recirculation
mode is selected to prevent dust, dirt and
pollen from entering the vehicle and cleans
the air inside of the vehicle with positive and
negative ions that are emitted from the ventilator.
After the 5 minutes, the sensor detects
exhaust gas and automatically alternates
between the recirculation mode and outside
air circulation mode.

WARNING
.Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
. Properly secure all cargo to help
prevent it from sliding or shifting.
Do not place cargo higher than the
seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. .
If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the
engine running for any extended
length of time.
. Keep the liftgate closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
liftgate open, follow these precau-
tions:
1) Open all the windows.
2) Set the
air recirculation to
off and the fan control to high to
circulate the air.
. If electrical wiring or other cable
connections must pass to a trailer
through the seal on the liftgate or the
body, follow the manufacturer’s re-
commendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service. — You suspect that exhaust fumes
are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
. The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
