OPERATING TIPS
●When the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for a
maximum of 150 seconds. However, this is
not a malfunction. After the coolant tempera-
ture warms up, air flow from the foot outlets
will operate normally.
The sunload sensor
1, located on the top center
of the instrument panel, helps the system main-
tain a constant temperature. Do not put anything
on or around this sensor. Rear seat temperature and fan speed can be
controlled from both the front seat overhead con-
sole controls
Aor the rear seat overhead con-
sole controls
B.
Press the REAR CTRL button to transfer control
of the rear climate functions to the rear passen-
gers.
To operate the rear air conditioner, the engine
must be running.
If the rear seat fan control dial is set to (0) , the air
conditioner is turned off. If it is set to any of the fan
speed positions, air is discharged from the rear
vents at the corresponding speed.

RADIO
Place the ignition switch in the ACC or ON
position and press the VOL (volume)/ON·OFF
(power) knob to turn the radio on. If you listen to
the radio with the engine not running, the ignition
switch should be placed in the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter, build-
ings, bridges, mountains and other external influ-
ences. Intermittent changes in reception quality
normally are caused by these external influences.
Using a cellular phone in or near the ve-
hicle may influence radio reception quality.
Radio reception
Your INFINITI radio system is equipped with
state-of-the-art electronic circuits to enhance ra-
dio reception. These circuits are designed to
extend reception range, and to enhance the qual-
ity of that reception.
However, there are some general characteristics
of both FM and AM radio signals that can affect
radio reception quality in a moving vehicle, even
when the finest equipment is used. These char-
acteristics are completely normal in a given re-
ception area, and do not indicate any malfunction
in your INFINITI radio system.Reception conditions will constantly change be-
cause of vehicle movement. Buildings, terrain,
signal distance and interference from other ve-
hicles can work against ideal reception. De-
scribed below are some of the factors that can
affect your radio reception.
Some cellular phones or other devices may
cause interference or a buzzing noise to come
from the audio system speakers. Storing the de-
vice in a different location may reduce or elimi-
nate the noise.
FM RADIO RECEPTION
Range: FM range is normally limited to 25 – 30 mi
(40 – 48 km) , with monaural (single channel) FM
having slightly more range than stereo FM. Exter-
nal influences may sometimes interfere with FM
station reception even if the FM station is within
25 mi (40 km) . The strength of the FM signal is
directly related to the distance between the
transmitter and receiver. FM signals follow a line-
of-sight path, exhibiting many of the same char-
acteristics as light. For example, they will reflect
off objects.
Fade and drift: As your vehicle moves away from
a station transmitter, the signals will tend to fade
and/or drift.
Static and flutter: During signal interference from
buildings, large hills or due to antenna position(usually in conjunction with increased distance
from the station transmitter) , static or flutter can
be heard. This can be reduced by adjusting the
treble control to reduce treble response.
Multipath reception: Because of the reflective
characteristics of FM signals, direct and reflected
signals reach the receiver at the same time. The
signals may cancel each other, resulting in mo-
mentary flutter or loss of sound.
AM RADIO RECEPTION
AM signals, because of their low frequency, can
bend around objects and skip along the ground.
In addition, the signals can be bounced off the
ionosphere and bent back to earth. Because of
these characteristics, AM signals are also sub-
ject to interference as they travel from transmitter
to receiver.
Fading: Occurs while the vehicle is passing
through freeway underpasses or in areas with
many tall buildings. It can also occur for several
seconds during ionospheric turbulence even in
areas where no obstacles exist.
Static: Caused by thunderstorms, electrical
power lines, electric signs and even traffic lights.

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation 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.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
● Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows 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 lift gate and rear vent windows
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
the lift gate or rear vent windows open,
follow these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
● The exhaust system and body should be
inspected by a qualified mechanic
whenever: a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by an INFINITI dealer.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than passen-
ger cars to make them capable of performing in a
variety of on-pavement and off-road applications.
This gives them a higher center of gravity than
ordinary cars. An advantage of higher ground
clearance is a better view of the road, allowing
you to anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form satisfactorily under off-road conditions. If at
all possible, avoid sharp turns at high speeds. As
with other vehicles of this type, failure to operate
this vehicle correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
