HEATER AND AIR CONDI-
TIONER OPERATION PRECAU-
TIONS
WARNING
.The heater and the air conditioner
operates only when the engine is
running.
. Never 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 pos-
sibly fatal injuries to people or ani-
mals.
. 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. .
Turn off the system when the engine
is not running to prevent battery
discharge.
INFO:
. Odors from inside and outside the vehi-
cle can build up in the air conditioner unit.
Odor can enter the passenger compart-
ment through the vents.
. 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.
. Vehicles with an automatic climate con-
trol system will automatically adjust the
passenger compartment to be the set
appropriate temperature when the re-
mote engine start feature (if so
equipped) is used.
For models with Idling Stop System (if so
equipped)
The Idling Stop System will not stop the
engine under the following conditions: .
The front defroster mode is on.
. The rear window defroster mode is on.
While the engine is stopped by the Idling
Stop System, taking one of the following
actions will automatically start the engine: . Turn the front defroster mode on.
. Turn the rear window defroster mode
on.
When the engine is stopped by the Idling
Stop System, performance of the heater and
air conditioner may be reduced to minimize
fuel consumption. For the best heating and
air conditioning performance, turn on the
[Use A/C While Idle] setting.

Without Advanced Climate Control system:
The Climate Control system is equipped with
an in-cabin microfilter that collects dirt,
pollen, dust, etc. To make sure that the air
conditioner heats, defogs and ventilates
efficiently, replace the filter in accordance
with the maintenance schedule in the vehicle
Owner’s Manual. To replace the filter, it is
recommended you visit an INFINITI retailer.The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.
SERVICING HEATER AND AIR
CONDITIONER
The heating and air conditioning 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. However, special charging equipment
and lubricant are required when servicing the
air conditioner. Using improper refrigerants
or lubricants will cause severe damage to
your Climate Control system. Refer to the
vehicle Owner’s Manual for heating and air
conditioning system refrigerant and lubri-
cant recommendations.
It is recommended you visit an INFINITI retailer to service your environmentally
friendly heater and air conditioning system.
WARNING
The 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.
REAR WINDOW AND OUTSIDE
MIRROR DEFROSTER
CAUTION
When cleaning the inner side of the rear
window, be careful not to scratch or
damage the rear window defroster.
To defog/defrost the rear window glass and
outside mirrors, start the engine and push
<
>. The indicator light on the button will
illuminate. Push the button again to turn off
the defroster.
The defroster will automatically turn off in
approximately 15 minutes.
If the engine is started using the remote start
function (if so equipped) when the outside
air temperature, the interior temperature
and the engine coolant temperature are
low, the rear window glass and outside
mirror defroster may turn on automatically.
For additional information about the remote
engine start function, refer to the vehicle
Owner’s Manual.
