seat.
. Any liquid spilled on the seat should
be removed immediately with a dry
cloth.
. The climate controlled seat has an air
filter. Do not operate climate con-
trolled seat without an air filter. This
may result in damage to the system.
. When cleaning the seat, never use
gasoline, thinner, or any similar ma-
terials.
. If any malfunctions are found or the
climate controlled seat does not op-
erate, turn the switch off and have
the system checked. It is recom-
mended you visit an INFINITI retailer
for this service.

The climate controlled seat cools down the
front seat by blowing cool air from under the
surface of the seat. The switches are located
on the instrument panel and can be operated
independently of each other.
1. Start the engine.
2. Push the climate controlled seat switch
to cool the seat. The indicator light
on
the corresponding switch will illuminate
depending on the cool level.
3. Adjust the desired amount of air by pushing the switch again. The climate
controlled seat blower remains on low
speed for approximately 60 seconds
after pushing the switch on. 4. When the vehicle’s interior is warmed or
cooled, or before you leave the vehicle,
be sure to turn off the climate controlled
seats. To turn off the climate controlled
seats, push the switch until the indicator
light turns off.
To check the air filter for the climate
controlled seat, it is recommended that you
visit an INFINITI retailer for this service.

OPERATING TIPS
When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate.
However, this is not a malfunction. After
the coolant temperature warms up, the air
flow from the foot outlets will operate
normally.
The sensors
andlocated on the instru-
ment panel help maintain a constant tem-
perature. Do not put anything on or around
the sensors.
IN-CABIN MICROFILTER
Models without Advanced Climate Control
System:
The climate control system is equipped with
an in-cabin microfilter which collects dirt,
pollen, dust, etc.
Models with Advanced Climate Control
System:
The climate control system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust, etc.
To make sure the air conditioner heats,
defogs, and ventilates efficiently, replace
the filter in accordance with the specified
maintenance intervals listed in the “9. Main-
tenance and schedules” section. If replace-
ment is required, it is recommended 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
conditioner.
SERVICING CLIMATE CONTROL
The climate control 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 your air conditioner.
Using improper refrigerants or lubricants will
cause severe damage to your climate control
system. (See “Capacities and recommended
fluids/lubricants” (P.10-2) for climate con-
trol system refrigerant and lubricant recom-
mendations.)
An INFINITI retailer will be able to service
your environmentally friendly climate control
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.
WINDOW ANTENNA
The antenna pattern is printed inside the 3rd
row seat window.
CAUTION
. Do not place metalized film near the
3rd row seat window or attach any
metal parts to it. This may cause poor
reception or noise.
. When cleaning the inside of the 3rd
row seat window, be careful not to
scratch or damage the 3rd row seat
window antenna. Lightly wipe along
the antenna with a dampened soft
cloth.

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving parts.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced
because the fuel lines are under high
pressure even when the engine is off. It is recommended you visit an
INFINITI retailer for this service.
CAUTION
.
Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-35).)
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and could
affect your warranty coverage. If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
