Operating tips
cKeep windows and sun roof closed while
the air conditioner is in operation.
cAfter 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
allows the air conditioner to cool the
interior more quickly.cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf 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 for additional in-
formation.

Servicing air conditioning
The air conditioning system in your NISSAN
is charged with a new refrigerant designed
with the environment in mind.
This new 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 causes severe damage to your
air conditioning system. See ``Air condition-
ing system refrigerant and lubricant recom-
mendations'' in the ``Technical and con-
sumer information'' section of this manual.
Your NISSAN dealer is able to service your
environmentally ``friendly'' air conditioning
system.
