Infiniti G37 Convertible (2009) [194/427] Servicing air conditioner
Ion control
The Advanced Climate Control System (ACCS)
adjusts the air quality in the passenger com-
partment by adding ions into the air blown from
the ventilators.
This function has two ion control modes,
“clean” and “ion control”. When the heater or
air conditioner is turned on, the clean mode
automatically starts operating and then
switches to the ion control mode. Each mode
alternates approximately every 15 minutes.
When in the automatic intake air control mode,
the clean mode operates for 30 minutes.
The current ion mode is indicated by the ion
indicator displayed on the screen.
Clean mode
Both positive ions and negative ions are
emitted from the ventilators, which helps
improve the air quality in the passenger
compartment by neutralizing airborne par-
ticles, such as dust, pollen and other impu-
rities. When the clean mode is operating, the
ion indicator illuminates in blue.
Ion control mode
Negative ions emitted from the ventilators
help purify the air in the passenger compart-
ment. When the ion control mode is operat-
ing, the ion indicator illuminates in green.
Exhaust gas detection sensor
This vehicle is equipped with an exhaust gas
detection sensor. When the automatic intake air
control is ON, the sensor detects pollutants
such as CO and NO
2
outside and the system
automatically changes from the outside air cir-
culation mode to the recirculation mode.
When the intake air control button is pushed
under the following conditions, the indicator
light on the
side will illuminate and the
exhaust gas detection sensor will turn on.
The air flow control is not in the front
defogger mode (the indicator light on the
front defogger 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.
SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains refrigerant
under high pressure. To avoid personal injury,
any air conditioner service should be done only
by an experienced technician with the proper
equipment.
The air conditioner system in your vehicle is
charged with a refrigerant designed with the
environment in mind.
