Operating tipsIKeep windows and sun roof closed while
the air conditioner is in operation.
IAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This will
allow the air conditioner to cool the interior
more quickly.
IThe air conditioning system should be
operated for about ten minutes at least
once a month. This helps prevent dam-
age to the system due to lack of lubrica-
tion.
IIf the coolant temperature gauge exceeds
the hot position, turn the air conditioner off.
For additional information, see ªIf your ve-
hicle overheatsº in the ª6. In case of emer-
gencyº section.AIR FLOW CHARTSThe following charts show the button and dial
positions formaximum and quickheating,
cooling or defrosting.The air recirculation
switch should always be in the off position
for heating and defrosting.4-6

Start the engine and operate the controls to
activate the air conditioner.IThe air conditioner cooling function
operates only when the engine is run-
ning.
IDo not leave children, unreliable
adults, or pets alone in your vehicle.
On hot, sunny days, temperatures in
a closed vehicle could quickly be-
come high enough to cause severe or
possibly fatal injuries to people or
animals.
IDo not use the recirculation mode for
long periods as it may cause the
interior air to become stale and the
windows to fog up.
IPositioning of the heating or air con-
ditioning controls should not be done
while driving, in order that full atten-
tion may be given to the driving
operation.

1. Push the AUTO button on. (AUTO will
appear on the display.)
2. Push the temperature control button
to set the desired temperature.
IFor normal operation, adjust the tempera-
ture control button to about 75ÉF (24ÉC).

: Air flow mainly from foot outlets.: Air flow from defroster and foot outlets.
To turn the system offPush the OFF button.OPERATING TIPSIWhen the engine coolant temperature and
outside air temperature are low, the air flow
from the foot outlets may not operate for 0
to 126 seconds. This is not a malfunction.
After the coolant temperature warms up, air
flow from the foot outlets will operate nor-
mally.
The sensor on the instrument panel helps
maintain a constant temperature. Do not put
anything on or around this sensor.The air conditioning system in your NISSAN
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 lu-
bricant are required when servicing your
NISSAN air conditioner. Using improper refrig-
erants or lubricants will cause severe damage
to your air conditioning system. See ªCapaci-
ties and recommended fuel/lubricantsº in the
ª10. Technical and consumer informationº sec-
tion for air conditioning system refrigerant and
lubricant recommendation.
Your NISSAN dealer will be able to service
your environmentally friendly air conditioning
system.
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 equip-
ment.
