Display screen, heater and air conditioner, and audio system4-27

WARNING
•The heater and air conditioner operate
only when the engine is running.
•Never leave children or adults who
would normally require the support of
others alone in the vehicle. Pets should
not be left alone either. They could un-
knowingly activate switches or controls
and inadvertently become involved in a
serious accident and injure themselves.
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 condi-
tioning controls while driving so that
full attention may be given to vehicle
operation.
The heater and air conditioner operate when
the engine is running. The air blower will op-
erate even if the engine is turned off and the
ignition switch is in the ON position.NOTE
•Condensation forms inside the air condi-
tioning unit when the air conditioner (if
equipped) is running, and is safely dis-
charged underneath your vehicle.
Traces of water on the ground are there-
fore normal.
•Odors from inside and outside the vehicle
can build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the ventilators.
When parking, set the heater and air con-
ditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle.
Observe the settings recommended on the
following pages. The windows could other-
wise mist up. To prevent the windows from
misting up
•Switch off climate control only briefly.
•Switch on air-recirculation mode only
briefly.
•Switch on the cooling with air dehumidifi-
cation function.
•Switch on the windshield demisting func-
tion briefly, if required.The air-conditioning system/automatic cli-
mate control regulates the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic cli-
mate control can only be operated when the
engine is running. Optimum operation is only
achieved with the side windows closed.
Always keep the ventilation flaps behind the
side panelling clear. Otherwise the vehicle will
not be ventilated correctly.
NOTE
•Ventilate the vehicle for a brief period
during warm weather. This will speed up
the cooling process and the desired inte-
rior temperature will be reached more
quickly.
•The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With automatic climate
control, gaseous pollutants and odors will
also be reduced. A clogged filter reduces
the amount of air supplied to the vehicle
interior. For this reason, you should al-
ways observe the interval for replacing
the filter, which is specified in the Service
Booklet. As this depends on environmen-
tal conditions, for example heavy air pol-
lution, the interval may be shorter than
stated in the Service Booklet.

SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal 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.
This refrigerant will not harm the earth’s
ozone layer.
Special charging equipment and lubricant are
required when servicing your vehicle’s air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to the air
conditioner system. (See "Air conditioner sys-
tem refrigerant and oil recommendations".)
An INFINITI retailer will be able to service
your environmentally friendly air conditioner
system.
Air conditioner filter
The air conditioner system is equipped with
an air conditioner filter. To make sure the air
conditioner heats, defogs, and ventilates ef-
ficiently, replace the filter in accordance with
the specified maintenance intervals listed in
the separate maintenance booklet. It is rec-
ommended you visit an INFINITI retailer for
this service.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air con-
ditioner.
