normal heating.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi- tion.
4. Turn the temperature control dial to the de- sired position between the middle and the
hot position.
Ventilation
This mode directs outside air to the side and
center ventilators.
1. Push the
button to the off position.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi- tion.
4. Turn the temperature control dial to the de- sired position.
Defrosting or defogging
This mode directs the air to the defrost outlets to

(2°C) . The air conditioning system will con-
tinue to operate until the vehicle is restarted,
even if the air flow control dial is turned to a
position other than the

Operating tips
cKeep the windows and sunroof closed while
the air conditioner is in operation.
c 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.
c 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.
c 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.
AIRFLOW CHARTS
The following charts show the button and dial
positions for MAXIMUM AND QUICK heating,
cooling or defrosting. The air recirculation
button should always be in the OFF posi-
tion for heating and defrosting.

WARNING
c The air conditioner cooling function op-
erates only when the engine is running. c
On hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or possi-
bly fatal injuries to people or animals.
Do not leave children or adults who
would normally require the support of
others in your vehicle. Unattended pets
should not be left alone either.
c 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. c
Positioning of the heater and/or air
conditioner controls should not be
done while driving so full attention may
be given to vehicle operation.
Start the engine and operate the controls to
activate the air conditioner.
AUTOMATIC OPERATION
Cooling and/or dehumidified heating

2. Turn the temperature dial to the left or right to set the desired temperature.
c Adjust the temperature dial to about 75°F
(25°C) for normal operation.
3. Turn the air flow control dial to AUTO. c The temperature of the passenger compart-
ment will be maintained automatically.
c Air flow distribution and fan speed are also

peratures above 36°F (2°C) . The air condi-
tioning system will continue to operate until
the vehicle is restarted, even if the air flow
control dial is turned to a position other than
the
position. This dehumidifies the air
which helps defog the windshield. The air
recirculate mode automatically turns off, al-
lowing outside air to be drawn into the pas-
senger compartment to further improve the
defogging performance.

OPERATING TIPS
cWhen 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 driver’s
side of the instrument panel, helps the system
maintain a constant temperature. Do not put any-
thing 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 lubricant recommendations” in the “Techni-
cal 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.
