2001 Lexus ES300 windshield

CAUTION
For effective protection in automobile accidents and
sudden stops, child must be properly restrained
using a seat belt or child restraint depending on age
and size. Holding a child in your arms is not a
substitute for a child restraint system. In an accident,
the child can be crushed against the windshield, or
between you and the vehicle's interior if you are
unrestrained.
 Lexus strongly urges use of a proper child restraint
which conforms to the size of the child, and is put on
the rear seat. According to accident statistics, the
child is safer when properly restrained in the rear
seat than in the front seat.

The air intake control button is used to switch the air
intake between the OUTSIDE AIR mode and
RECIRCULATED AIR mode.
With the button in the OUTSIDE AIR mode, the
OUTSIDE AIR mode indicator light will come on and the
system will take fresh outside air into the vehicle.
If quick circulation of cooled air is desired, push the air
intake control button for RECIRCULATED AIR. The
RECIRCULATED AIR mode indicator light will come on.
For 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.
When the air conditioning is ON, if the engine coolant
temperature becomes extremely high, the
RECIRCULATED AIR mode is automatically selected.
This is not a malfunction. When the engine coolant
temperature is lowered, the previous mode resumes.
If manual on±off of the air conditioning is desired ±
Push the ªA/Cº 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 year±round automatic temperature
control including cooling and dehumidifying
operation.
If the air conditioning compressor does not operate, the
indicator of the ªA/Cº button will blink. If the indicator of
the ªA/Cº button blinks even when the ªA/Cº button is
pushed again, have the compressor checked by your
nearest Lexus dealer.
Displaying the outside temperature ±
When you push the ªOUTSIDE TEMPº knob, the
temperature display shows the outside temperature. To
return to the display of the current set temperature, push
the knob again. The temperature display ranges from
±30 C (±22 F) up to 50C (122F).

To remove interior fog on the windshield ±
Push the ªFRONT WINDSHIELDº button.
To remove frost or exterior fog on the windshield ±
1. Turn the ªTEMPº knob at the maximum temperature.
2. Push the ªFRONT WINDSHIELDº button.
3. Push the fan speed control button on the right side to
obtain a maximum air flow.
4. Leave the air conditioning on±off button off.
When the ªFRONT WINDSHIELDº button is pushed, air
flows mainly from the windshield vents and the
OUTSIDE AIR mode is automatically set. This setting
clears the front view more quickly.
If you want to return the setting to RECIRCULATED AIR
mode, push the air intake control button once again.
Pushing the ª
FRONT WINDSHIELDº button turns on the
defroster±linked air conditioning. At this time, the ªA/Cº
button indicator comes on regardless of whether or not
the ªA/Cº button is pushed in. This is to clean up the front
view more quickly.
To turn off the air conditioning alone, push the ªA/Cº
button once again.
When the ªA/Cº button is not pushed in, pushing another
air flow control button turns off the air conditioning.
Pushing the ªFRONT WINDSHIELDº button once again
returns the air flow mode to the last one used.
CAUTION
Do not use the ªFRONT WINDSHIELDº 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
dashboard vents. (See ªSide ventsº.)
 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, push the fan speed selector to adjust
the fan speed 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 ªOFFº button. 
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.
Heating
For best results, set controls to:
For automatic operation ±
Push in the ªAUTOº button.
