--Air flow selector settings --Operating tips
D To cool off your Toyota after it has
been parked in the hot sun, drive with
the windows open for a few minutes.
This vents the hot air, allowing the air
conditioning to cool the interior more
quickly.
D Make sure the air intake grilles in front
of the windshield are not blocked (by
leaves or snow, for example).
D On humid days, do not blow cold air
on the windshield. The windshield could
fog up because of the difference in air
temperature on the inside and outside
of the windshield.
D Keep the area under the front seats
clear to allow air to circulate through-
out the vehicle.
D On cold days, set the fan speed to
high for a minute to help clear the
intake ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.
D When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
FRESH and the fan speed selector to
any setting except "OFF".

--Checking and replacing the
air conditioning filter
The air conditioning filter may clog af-
ter long use. The filter may need to be
replaced if the air flow of the air condi-
tioning and heater experiences extreme
reductions in operating efficiency, or if
the windows begin to fog up easily.
To maintain the air conditioning efficiency,
inspect and replace the air conditioning
filter according to the maintenance sched-
ule. In dusty areas or areas with heavy
traffic flow, such as inner city or desert
areas, early replacement may be required.

INFORMATION
The air filter should be installed prop-
erly in position. The use of air condi-

may cause deteriorated dustproof per-
