NOTICE
The automatic air conditioning automatically maintains
the set temperature.
To prevent the battery from being discharged, do not
leave the air conditioning on longer than necessary
when the engine is not running.
In the automatic operation mode, the air conditioning selects
the most suitable fan speed, air flow, air intake and on–off of
the air conditioning according to the temperature.
The ignition key must be in the ”ON” position.

(a) Climate control
SETTING OPERATION – automatic control
SV21018
1. Set the air flow control dial and the fan speed control
dial to ”AUTO” positions.
An indicator light will illuminate to show that the automatic
operation mode has been selected.
Air flow quantity and switching of the diffusers are
automatically adjusted.
When one of the manual control dials is turned while operating
in automatic mode, the operation corresponding to the dial
turned is set. Other conditions continue to be adjusted
automatically.
When the fan speed control dial is turned to ”OFF”, the fan is
turned off.
If the ”A/C” button indicator flashes, there is a problem in the
air conditioning system and the air conditioning automatically
shuts off. If this happens, take your vehicle to your Lexus
dealer for service.

2. Turn the temperature control dial to set the desired
temperature.
The temperature control dial is used to set the desired
passenger compartment temperature. The temperature of air
delivered to the passenger compartment will be controlled
automatically according to the setting. The figures on the
panel indicate degrees Fahrenheit.
When you adjust the temperature control dial to maximum
cooling, the air intake mode will be automatically changed to
RECIRCULATED AIR.

SETTING OPERATION – manual control
Press the ”A/C” button for dehumidified heating or
cooling. This setting clears the front view more quickly.
If manual air flow selection is desired –

Windshield – Air flows mainly from the windshield vents.
Set the air flow control dial to the windshield position turns
on the defogging function with the purpose of clearing the
front view.
SV21017
This position allows the air intake to select FRESH
automatically. This is to clean up the front view more
quickly.
If you want to return the setting to RECIRCULATE mode,
press the air intake selector button one again.
The outlets from which air is delivered can be selected
manually by pushing the button. The function of each mode is
as follows:
1
Panel – Air flows mainly from the instrument panel vents.
2
Bi–level – Air flows from both the floor vents and the
instrument panel vents.
3
Floor – Air flows mainly from the floor vents.
4
Floor/Windshield – Air flows mainly from the floor vents
and windshield vents.
Press ”A/C” button for dehumidified heating or cooling.
This setting clears the front view more quickly.
Set the air flow control dial to the floor/windshield position
turns on the defogging function with the purpose of
clearing the front view.
Use with the air intake control positioned in fresh.

AIR CONDITIONING
If manual fan speed control is desired –
SV21023
1 Fan speed at low
2 Fan speed at high
The fan speed can be set to your desired speed by turning the
fan speed control dial. The higher the fan speed is, the more
air is delivered. Turning the dial to ”OFF” turns off the fan.
To remove exterior windshield frost, use the high speed
setting.
If manual switching of air intake is desired –
SV21024a
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 you adjust the airflow control dial and the fan speed
control dial to ”AUTO” positions in case that the room
temperature is much higher than the set temperature, the air
intake mode will be automatically changed to
RECIRCULATED AIR.

AIR CONDITIONING
However, once selecting ”RECIRCULATED AIR” of the air
intake manually will make this function inoperable. In order to
make this function operable again, first select ”OUTSIDE AIR”
of the air intake, turn off the ignition switch, and start the engine
again. Then this function return to be operable.
(b) Windshield defogging and defrosting
If manual on–off 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.
SV21016
The air conditioning does not work if the outside temperature
is lowered down to around 0C (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 ”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.
To remove interior fog on the windshield –
1. Turn the air flow control dial to ”WINDSHIELD”.
2. Set the ”OUTSIDE AIR” mode.
To remove frost or exterior fog on the windshield –
1. Turn the temperature control dial to the maximum
temperature.
2. Turn the air flow control dial to ”WINDSHIELD”.
3. Turn the fan speed control dial to ”HI”.
4. Leave the air conditioning on–off button off.

AIR CONDITIONING
CAUTION
Do not use the ”FRONT WINDSHIELD” 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) Air filter
The air filter may clog after long use which will reduce the air
flow. However, you can inspect the filter easily.
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 efficiency,
or if the windows become to fog up easily.
When you inspect and replace the air filter, be sure to turn off
the fan.

1. Remove the glove box.
Remove belongings stored in the glove box, and remove the
two pins installed on the lower part of the glove box, and
remove the glove box.

AIR CONDITIONING
(d) 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.
SV21015
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 ”Center vents” and ”Side vents”.)
2. Remove the cover and take out the air filter
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.
If it is dirty, it should be replaced. To maintain the air
conditioning efficiency, replace the air filter according to the
maintenance schedule. (For scheduled maintenance
information, please refer to the ”Owner’s Manual Supplement
/ Scheduled Maintenance”.)
Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
INFORMATION
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 dial be turned to anywhere except the ”OFF”
button.
The air filter should be installed properly in position.
The use of air conditioning with the air filter removed
may cause deteriorated dustproof performance and
then affect air conditioning performance.
On cold days, set 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.
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.
