adults, or pets alone in your vehicle.
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.cDo 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.
cPositioning of the heating or air con-
ditioning controls should not be
done while driving, in order that full
attention may be given to the driving
operation.

Operating tips
cKeep the windows and sun roof closed
while the air conditioner is in operation.
cAfter parking in the sun, drive for two orthree 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 conditioner 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
exceeds the H (hot) position, turn the air
conditioner off. See ``If your vehicle over-
heats'' in the ``In case of emergency''
section of this owner's manual for addi-
tional information.

Servicing air conditioner
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. See ``Air conditioner
system refrigerant and lubricant recommen-
dations'' in the ``Technical and consumer
information'' section of this manual.
Your NISSAN dealer is able to service your
environmentally conscious air conditioner
system.
WARNING
The air conditioner system contains
refrigerant under high pressure. To
avoid personal injury, any air condi-
tioner service should be done only by
an experienced technician with proper
equipment.
