Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position.
∙ When the
orare selected,
the air conditioner automatically turns
on if the outside temperature is more
than 36°F (2°C). This dehumidifies the air
which helps defog the windshield.
The
mode automatically turns off,
allowing outside air to be drawn into the
passenger compartment to further im-
prove the defogging performance.
∙ The air conditioner is always on in
mode, regardless of whether the indica-
tor light is on or off.
3. Turn the temperature control dial to the desired position.
Operating tips
∙ Keep the windows and moonroofclosed while the air conditioner is in op-
eration.
∙ Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to
vent hot air from the passenger com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior more quickly.
∙ The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent damage to the
system due to lack of lubrication.
∙ 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 malfunction.
∙ If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.

selves 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.
∙ Do not use the recirculation mode for long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.

OPERATING TIPS
The sunload sensor, located on the top
passenger’s side of the instrument panel,
helps the system maintain a constant
temperature. Do not put anything on or
around this sensor.∙ 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. Af ter
the coolant temperature warms up, air
flow from the foot outlets will operate
normally. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth’s ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem (if so equipped) refrigerant and oil rec-
ommendations” in the “Technical and con-
sumer information” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper
equipment.
RADIO
Place the ignition switch in the ACC or ON
position and press the PUSH
button 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 sig-
nal strength, distance from radio transmit-
ter, buildings, bridges, mountains and other
external influences. Intermittent changes
in reception quality normally are caused by
these external influences.
Using a cellular phone in or near the vehicle
may influence radio reception quality.
Radio reception
Your NISSAN radio system is equipped with
state-of-the-art electronic circuits to en-
hance radio reception. These circuits are
designed to extend reception range, and to
enhance the quality of that reception.
However, there are some general charac-
teristics 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 characteristics
are completely normal in a given reception
area and do not indicate any malfunction
in your NISSAN radio system.

WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves 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.
∙ 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; theycontain 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 ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these 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 trunk lid or the
body, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry 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,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol 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.
