the air intake control to the fresh air ( )
position and fan speed to the desired posi-
tion.
o When the A/C is operated continuously on
the floor-defrost level ( ) or defrost level
( ), it may cause fog to form on the exterior
windshield by the temperature differencial.

B760A06Y-AATAIR CONDITIONER FILTER (FOR
EVAPORATOR AND BLOWER UNIT)
(If installed)
The air conditioner filter is located in the evapo-
rator behind the glove box.
It operates to decrease pollutants the amount of
entering the car.
CAUTION:o Replace the filter every 12,000 miles
(20,000 km) or once a year.
If the car is being driven in severe condi-
tions such as dusty, rough roads, more
frequent air conditioner filter inspec-
tions and changes are required.
o When the air flow rate is suddenly de-
creased, it must be checked at an autho-
rized dealer.
o If your vehicle is not equipped with this
filter, it can be installed by your dealers.
Check with your dealer for details.
!
B740D01Y-AATOperation Tips
o 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.
