AIR CONDITIONING
164For normal use, it is best to keep the air intake control button
set to OUTSIDE AIR mode. If recirculated air is used during
heating, the windows will fog up more easily.
If manual onoff of the air conditioning is desired
Push the “A/C”
button to turn the air conditioning on and push
it again to turn the air conditioning off.
The air conditioning does not work if the outside temperature
is lowered down to around 0 C (32F).
If the system is used for ventilation, heating in dry weather or
removing frost or exterior fog on the windshield, turn the air
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for yearround
automatic temperature control including cooling and
dehumidifying operation.
If the air conditioning compressor does not operate, the
indicator of the “A/C” button will blink. If the indicator of the
“A/C” button blinks even when the “A/C” button is pushed
again, have the compressor checked by your nearest Lexus
dealer.
Displaying the outside temperature
The temperature display ranges from 30 C (22F) up to
50 C (122 F).
(b) Windshield defogging and defrosting
To remove interior fog on the windshield
Push the windshield air flow button.
To remove frost or exterior fog on the windshield
1. Push the “TEMP” button to set the maximum temperature.
2. Push the windshield air flow button.
3. Push the fan speed control button on the right side to obtain
a maximum air flow.
4. Leave the “A/C” button off.
When the windshield air flow button is pushed, air flows mainly
from the windshield vents and turns on the defogging function
with the purpose of clearing the front view.
Pushing this button once again returns the air flow mode to the
last one used.

AIR CONDITIONING
165
This
button allows the air intake to select OUTSIDE AIR mode
automatically. This is to clean up the front view more quickly.
If you want to return the setting to RECIRCULATED AIR mode,
push the air intake control button once again.
Push the “A/C” button for dehumidified heating or cooling. This
setting clears the front view more quickly.
CAUTION
Do not use the windshield air flow button during cooled
air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
(c) Operating tips
 To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
 Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
 If air flow control is not satisfactory, check the side vents and
rear vents. (See “(d) Side vents and rear vents”.)
 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.
 Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
 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.
 When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
control button be left to the OUTSIDE AIR mode and the fan
speed control button be pressed to anywhere except the
“OFF” button.

AIR CONDITIONING

If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.

(e) Checking and replacing the airconditioning filter
The air conditioning filter is behind the glove box.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioner and
heater experiences extreme reductions in operating ef ficiency,
or if the windows become to fog up easily.
To maintain the air conditioning ef ficiency, inspect and replace
the air conditioning filter according to the maintenance
schedule. (For scheduled maintenance information, please
refer to the “Owner’s Manual Supplement/Scheduled
Maintenance”.)
1. Open the glove box. Remove the screw with a
Phillipshead screwdriver.
2. Remove the 2 pins installed on the upper part of the
glove box and lower the glove box.

3. Take out the filter case.
4. Remove the filter from the filter case.
5. Inspect the filter on the surface.
If it the dirty, it should be replaced.
INFORMATION
The air conditioning filter should be installed properly
in position. The use of air conditioning with the filter
removed may cause deteriorated dustproof
performance and then affect air conditioning
performance.
