HEATER AND AIR CONDITIONER OPERA-
TION PRECAUTIONS
WARNING!
.The heater and the air conditioner
operates only when the engine or the
hybrid system 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 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.
. Turn off the system when the engine or
the hybrid system is not running to
prevent battery discharge.
INFO:
.
Odors from inside and outside the vehicle
can build up in the air conditioner unit. Odor
can enter the passenger compartment
through the vents.
.When parking, set the heater and air
conditioner controls to turn off air recircula-
tion to allow fresh air into the passenger
compartment. This should help reduce
odors inside the vehicle.

AUTOMATIC CLIMATE CONTROL SYSTEM
AUTOMATIC OPERATION
Cooling and/or dehumidified heat-

system works automatically to control the
inside temperature, air flow distribution
and fan speed after the preferred tempera-
ture is set manually.

button will illuminate and “AUTO”will
be displayed on the CLIMATE screen.)
2. Push <
>and <>on the driver’s
side to set the desired temperature.

compartment will be maintained auto-
matically. Air flow distribution and fan
speed will also be controlled automa-
tically.

can individually set the driver’s and
front passenger side temperatures by
pushing <

A visible mist may be seen coming from the
ventilators in hot, humid conditions as the air is
cooled rapidly. This does not indicate a mal-
function.

Without Advanced Climate Control system:
The Climate Control system is equipped
with an in-cabin microfilter that collects
dirt, pollen, dust, allergens (such as
pollen, tick shells), etc. To make sure that
the air conditioner heats, defogs and
ventilates efficiently, replace the filter in
accordance with the maintenance schedule
in the INFINITI Service and Maintenance
Guide. To replace the filter, contact 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 CON-
DITIONER
The heating and air conditioning system in
your INFINITI 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 your INFINITI air conditioner.
Using improper refrigerants or lubricants
will cause severe damage to your Climate
Control system. Refer to Vehicle Owner’s
Manual for heating and air conditioning system refrigerant and lubricant recom-
mendations.
Your INFINITI retailer will be able 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.
HEATED SEATS (if so equipped)
WARNING!
Do not use or allow occupants to use the seat
heater if you or the occupants cannot
monitor elevated seat temperatures or have
an inability to feel pain in those body parts in
contact with the seat. Use of the seat heater
by such people could result in serious injury.
CAUTION!
.
The battery could run down if the seat
heater is operated while the engine or
the hybrid system is not running.
. Do not use the seat heater for extended
periods or when no one is using the seat.
. Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
. Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
