Operating tips
IKeep windows and sunroof closed while
operating the air conditioner.
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
allows 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, especially in winter. This
helps prevent damage to the system due
to lack of lubrication.
IIf the coolant temperature gauge ex-
ceeds the (hot) position, turn the air
conditioner off. Have your vehicle in-spected by a NISSAN dealer. See ``If
your vehicle overheats'' in the ``In case of
emergency'' section for additional infor-
mation.
