3-1. Using the air conditioning system and defogger
■Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode in sit-
uations where the windows need to be defogged.
■When micro dust and pollen filter is active
●In order to prevent the windshield from fogging up when the outside air is cold,
the following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The air conditioning syst em operates automatically.
• The operation cancels after 1 minute.
●In rainy weather, the windows may fog up. Press .
■When outside air temperature is below 32 F (0C)
The cooling and dehumidification func tion may not operate even when
is
pressed.
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning sy stem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic mode.
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air oper ation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.

4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
■When working on the engine compartment
●Make sure that the indicator on the “POWER” switch and the “READY” indicator
are both off.
●Keep hands, clothing and tools away from the moving fans and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold,
etc. right after driving as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fans or radiator grille
Be sure the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is high.
(  P. 4 3 6 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to
dirt in the air. Also, a backfire could cause a fire in the engine compartment.

Maintenance and care
■Checking interval
Inspect, clean and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, early replacement may be
required. (For scheduled maintenance information, please refer to the “Owner’s
Manual Supplement” or “Scheduled Maintenance”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
Slide and pull out the filter.
Replace the filter with a new
one.
The “ UP” mark shown on the
filter should be pointing up.
■ Cleaning method
If the filter is dirty, clean by blow-
ing compressed air through the
filter from the underside.
Hold the air gun 2 in. (5 cm)
from the filter and blow for
approximately 2 minutes at
72 psi (500 kPa, 5.0 kgf/cm
2
or bar).
If an air gun is not available,
have the filter cleaned by
your Lexus dealer.
