normally.
The sensors
and, located on the
instrument panel, help maintain a constant
temperature. Do not put anything on or
around the sensors.
SERVICING AIR CONDITIONER
WARNING
The air conditioner contains refrigerant
under high pressure. To avoid personal
injury, any air conditioner service should
be done only by an experienced techni-
cian 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. However, it may contribute in a
small part to global warming.
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 conditioning
system refrigerant and oil recommenda-
tions” (P.10-7).)
An INFINITI retailer will be able to service your environmentally friendly air conditioner
system.
In-cabin microfilter
With Advanced Climate Control system:
The air conditioning system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust, etc.
To make sure that the air conditioner heats,
defogs and ventilates efficiently, replace the
filter in accordance with the specified main-
tenance intervals shown in the “9. Main-
tenance and schedules” section. 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.
Without Advanced Climate Control system:
The air conditioning 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 specified main-
tenance schedule shown in the “9. Main-
tenance and schedules” section. 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.

WINDOW ANTENNA
The antenna pattern is printed inside the
rear window.
CAUTION
.Do not place metalized film near the
rear window glass or attach any
metal parts to it. This may cause poor
reception or noise.
. When cleaning the inside of the rear
window, be careful not to scratch or
damage the rear window antenna.
Lightly wipe along the antenna with
a dampened soft cloth.
JVH0641X
SATELLITE RADIO ANTENNA
There is a satellite radio antenna on the rear
part of the vehicle roof.
CAUTION
.A buildup of ice on the satellite radio
antenna can affect satellite radio
performance. Remove the ice to re-
store satellite radio reception.
. When removing snow from the roof,
do not apply strong force to the
satellite radio antenna. That may
cause broken satellite radio antenna
and roof panel dent. .
When using a high pressure car wash,
keep the high pressure nozzle away
from the satellite radio antenna. The
seal may be deformed or damaged.
. The radio performance may be af-
fected if cargo carried on the roof
blocks the radio signal. If possible, do
not put cargo near the satellite radio
antenna.
ANTENNA

When installing a car phone or a CB radio in
your vehicle, be sure to observe the follow-
ing cautions, otherwise the new equipment
may adversely affect the electronic control
modules and electronic control system har-
ness.
WARNING
.A cellular phone should not be used
for any purpose while driving so full
attention may be given to vehicle
operation. Some jurisdictions prohibit
the use of cellular phones while
driving.
. If you must make a call while your
vehicle is in motion, the hands-free
cellular phone operational mode (if so
equipped) is highly recommended.
Exercise extreme caution at all times
so full attention may be given to
vehicle operation.
. If a conversation in a moving vehicle
requires you to take notes, pull off
the road to a safe location and stop
your vehicle before doing so.
CAUTION
.Keep the antenna as far away as
possible from the electronic control
modules.
. Keep the antenna wire more than 8 in
(20 cm) away from the electronic
control system harness. Do not route
the antenna wire next to any harness.
. Adjust the antenna standing-wave
ratio as recommended by the manu-
facturer.
. Connect the ground wire from the CB
radio chassis to the body.
. For details, it is recommended you
visit an INFINITI retailer.

5-4Starting and driving
WARNING
.Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, 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.
. Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
. If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the
engine running for any extended
length of time.
. Keep the trunk lid closed while driv-
ing, otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
trunk lid open, follow these precau-
tions:
1) Open all the windows.
2) Set the air recirculation to off and the fan control to high to circulate
the air. .
If electrical wiring or other cable
connections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service.
— You suspect that exhaust fumes are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
