B740D02Y-AATOperation Tipso If the interior of the car is hot when you first
get in, open the windows for a few minutes
to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.
