Advanced Climate Control System
(if so equipped)
The Advanced Climate Control System keeps the air inside of the vehicle clean,
using the ion control and the automatic air
intake control with exhaust gas detecting
sensor.
Ion control:
This unit generates highly concentrated
Plasmacluster
®ions into the air blown from
the ventilators and reduces odor absorbed
into the interior trim.
The high-density Plasmacluster
®ions gen-
erated in the air conditioner’s air stream not
only suppress airborne bacteria and reduce
the adherence of odors to the interior trim,
but also have a proven skin moisture pre-
serving effect.
When the air conditioner is turned on, the
system generates Plasmacluster
®ions auto-
matically.
The amount of Plasmacluster
®ions in-
creases according to the amount of air flow.
When the air flow is high,
is displayed on
the display screen and when the air flow is
low, the indication in the screen changes to

industry odors such as pulp or chemicals, and
exhaust gas such as gasoline or diesel. When
such odors or gas are detected, the system
automatically changes from the outside air
circulation mode to the recirculation mode.
When the
button is pushed under the
following conditions, the indicator light on
the button will illuminate and the exhaust
gas detection sensor will turn on.
. The air flow control is not in the front
defroster mode. (The indicator light on

. The outside temperature is about 32°F
(0°C) or more.
When the automatic intake air control is ON,
for the first 5 minutes, the recirculation
mode is selected to prevent dust, dirt and
pollen from entering the vehicle and cleans
the air inside of the vehicle with positive and
negative ions that are emitted from the
ventilator.
After the 5 minutes, the sensor detects
exhaust gas and automatically alternates
between the recirculation mode and outside
air circulation mode.

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.
LINKING INTELLIGENT KEY
The air conditioner system settings can be
memorized for each Intelligent Key. See
“Setting memory function” (P.3-41).
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.

cause a malfunction of the tire pres-
sure sensors.
CAUTION
.The TPMS may not function properly
when the wheels are equipped with
tire chains or the wheels are buried in
snow.
. Do not place metalized film or any
metal parts (antenna, etc.) on the
windows. This may cause poor recep-
tion of the signals from the tire
pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate. Some examples
are:
. Facilities or electric devices using similar
radio frequencies are near the vehicle.
. If a transmitter set to similar frequencies
is being used in or near the vehicle.
. If a computer (or similar equipment) or a
DC/AC converter is being used in or near
the vehicle.
Low tire pressure warning light may illumi- nate in the following cases.
.
If the vehicle is equipped with a wheel
and tire without TPMS.
. If the TPMS has been replaced and the ID
has not been registered.
. If the wheel is not originally specified by
INFINITI.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals outside
the vehicle to help you inflate the tires to the
recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and place the
shift lever in the P (Park) position.
3. Place the ignition switch in the ON position. Do not start the engine.
Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indica- tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than
approximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly
to release pressure. When the pressure
reaches the designated pressure, the
Starting and driving5-7

5-8Starting and driving
horn beeps once.
. If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the Tire Inflation Indicator is not
operating.
. The TPMS will not activate the Tire
Inflation Indicator under the following
conditions:
— If there is interference from an ex- ternal device or transmitter
— The air pressure from the inflation device such as those using a power
socket is not sufficient to inflate the
tire
— If an electrical equipment is being used in or near the vehicle
— There is a malfunction in the TPMS system
— There is a malfunction in the horn or hazard indicators
. If the Tire Inflation Indicator does not
operate due to TPMS interference, move
the vehicle about 3 ft (1m) backward or
forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle. As with any vehicle, a loss of
control could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways. Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence
of alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt as
outlined in the “Seat belts” (P.1-18), and also
instruct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or killed than a person properly wearing a seat
belt.
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
passenger 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 passenger cars any more than
low-slung sports cars are designed to per-
form satisfactorily under off-road condi-
tions. If at all possible, avoid sharp turns or
abrupt maneuvers, particularly 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.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or killed
than a person properly wearing a seat belt.
Be sure to read “Driving safety precautions”
(P.5-10).

OFF-ROAD RECOVERY
While driving, the right side or left side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure
below. Please note that this procedure is
only a general guide. The vehicle must be
driven as appropriate based on the condi-
tions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steeringwheel with both hands and try to hold
a straight course.
4. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the
vehicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to stay
in the appropriate driving lane.
.If you decide that it is not safe toreturn the vehicle to the road surface
based on vehicle, road or traffic conditions, gradually slow the vehicle
to a stop in a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the
handling and stability of the vehicle, espe-
cially at highway speeds.
Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspect the tires for wear and
damage. See “Wheels and tires” (P.8-27).
If a tire rapidly loses air pressure or “blows-
out” while driving maintain control of the
vehicle by following the procedure below.
Please note that this procedure is only a
general guide. The vehicle must be driven as
appropriate based on the conditions of the
vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
.
The vehicle generally moves or pulls
in the direction of the flat tire.
. Do not rapidly apply the brakes.
. Do not rapidly release the accelerator
pedal.
. Do not rapidly turn the steering
wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold
a straight course.
3. When appropriate, slowly release the accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible.
5. Lightly apply the brake pedal to gradu- ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emergency
service to change the tire or see “Chan-
ging a flat tire” (P.6-4).

ABOUT LOWERING OF THE
REAR OF THE VEHICLE
If the loaded vehicle is not moved for a long
time, the vehicle rear body may be to lower.
But it is normal. Once the engine starts, It
will automatically adjust vehicle height.
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the bloodstream
reduces coordination, delays reaction
time and impairs judgement. Driving
after drinking alcohol increases the like-
lihood of being involved in an accident
injuring yourself and others. Addition-
ally, if you are injured in an accident,
alcohol can increase the severity of the
injury.
INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people differently and most people underestimate
the effects of alcohol.
Remember, drinking and driving don’t mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs).
Don’t drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or some
other physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is
mainly designed for leisure use, unlike a
conventional off-road vehicle.
Remember that Two-Wheel Drive (2WD)
models are less capable than Four-Wheel
Drive (4WD) models for rough road driving
and extrication when stuck in deep snow,
mud, or the like.
Please observe the following precautions:
WARNING
.
Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving over rough terrain.
. Do not drive across steep slopes.
Instead drive either straight up or
straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.
. Many hills are too steep for any
vehicle. If you drive up them, you
may stall. If you drive down them,
you may not be able to control your
speed. If you drive across them, you
may roll over.
. Do not shift ranges while driving on
downhill grades as this could cause
loss of control of the vehicle.
. Stay alert when driving to the top of
a hill. At the top there could be a
drop-off or other hazard that could
cause an accident.
. If your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
range. Never back down in N (Neu-
tral), using only the brake, as this
could cause loss of control.
. Heavy braking going down a hill
could cause your brakes to overheat

ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tem-
perature with heavy loads, such as when
towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function may
be automatically turned OFF for a short
time (the blower will continue to oper-
ate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shift or upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function
will automatically be turned back ON. If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant tempera-
ture gauge does not return to the normal
range from the H position, this may
indicate a malfunction. Move the vehicle
off the road to a safe area and allow the
engine to cool. If after checking the oil
and coolant, the
remains on or
engine coolant temperature does not
return to the normal range, do not
continue to drive. It is recommended
you contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic, which could increase the chance of a
collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. See
“If your vehicle overheats” (P.6-14).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
