WARNING
●The air conditioner cooling function op-
erates only when the engine is running.
● 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.
● Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.

full HOT position.
● When the
position is selected, the air
conditioner automatically turns on (the indi-
cator light on the
button will come on)
if the outside temperature is more than 36°F
(2°C) . This dehumidifies the air which helps
defog the windshield. The
mode au-
tomatically turns off, allowing outside air to
be drawn into the passenger compartment
to further improve the defogging perfor-
mance.
Bi-level heating
The bi-level mode directs warmed air to the side
and center vents and to the front and rear floor
outlets.
1. Press the
button to the OFF position.
2. Press the

side temperature is more than 36°F (2°C) .
The indicator light on the A/C button will
come on. This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing out-
side air to be drawn into the passenger
compartment to further improve the defog-
ging performance.
Operating tips
Clear snow and ice from the wiper blades
and air inlet in front of the windshield. This
improves heater operation.

air flow control button.
2. Turn the fan control dial to the desired posi- tion.
3. Press the
button. The indicator light
comes on. When the
orare selected, the air
conditioner automatically turns on (the indicator
light will illuminate) 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 improve the defogging performance.
4. Turn the temperature control dial to the de- sired position.
Operating tips
●Keep the windows and moonroof closed
while the air conditioner is in operation.
● After parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
● The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent 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. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

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, located on the top of the
instrument panel on the driver’s side, helps the
system maintain a constant temperature. Do not
put anything on or around this sensor. The air conditioner system in your NISSAN ve-
hicle is charged with a refrigerant designed with
the environment in mind.
This refrigerant does not harm the earth’s
ozone layer.
Special charging equipment and lubricant is re-
quired when servicing your NISSAN air condi-
tioner. Using improper refrigerants or lubricants
will cause severe damage to your air conditioner
system. See “Air conditioner system refrigerant
and oil recommendations” in the “Technical and
consumer information” section of this manual.
A NISSAN dealer is able to service your “environ-
mentally 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.
