(a) Climate control
SETTING OPERATION automatic control
1. Push the “AUTO” button.
An indicator light will illuminate to show that the automatic
operation mode has been selected.
Air flow quantity, switching of the diffusers, on−off of the air
conditioning and switching of the air intake between
RECIRCULATED AIR and OUTSIDE AIR are automatically
adjusted. The operation status is shown by each indicator.
When one of the manual control buttons is depressed while
operating in automatic mode, the operation corresponding to
the button depressed is set. Other conditions continue to be
adjusted automatically.
Push the “OFF” button to turn the air conditioning system off.
2. Use the “TEMP” or “PASSENGER TEMP” button to set
the desired temperature.
The “TEMP” or “PASSENGER TEMP” button is used to set the
desired temperature. The temperature will be controlled on the
driver and passenger sides simultaneously or individually.
“TEMP” button Changes the temperature on the driver and
passenger sides simultaneously or the driver side only.
“PASSENGER TEMP” button Changes the temperature on
the passenger side only.
“DUAL” button Changes the mode of the temperature
setting.
The indicator on the “DUAL” button has two modes:
 With the indicator on For individual temperature setting
 With the indicator off For simultaneous temperature
setting

AIR CONDITIONING
184If quick heating or cooling is desired
Push the “TEMP” or “PASSENGER TEMP” button on either
side
and hold it until “MAX. HOT” or “MAX. COLD” appears on
the display.
If manual fan speed control is desired
 1 Fan speed at low 2 Fan speed at high
The fan speed can be set to your desired speed by pushing the
appropriate side of fan speed control button. The higher the fan
speed is, the more air is delivered. Pushing the “OFF” button
turns off the fan.
To remove exterior windshield frost, use the high speed setting. If manual switching of air intake is desired
Each time you push the air intake control button, the mode
changes in order from the RECIRCULATED AIR mode to
OUTSIDE AIR mode, then back to the RECIRCULATED AIR
mode. Each indicator light shows which mode is now
selected.
1RECIRCULATED AIR mode If quick circulation of
cooled air is desired, select this mode.
2OUTSIDE AIR mode The system will take fresh outside
air into the vehicle.
To prevent fogging up of the windshield, the air intake mode
may change automatically to the OUTSIDE AIR mode
depending on the condition of the air conditioning system.
For example, when the ambient temperature is low, the air
intake mode may change automatically to the OUTSIDE AIR
mode. This is not a malfunction.

AIR CONDITIONING
185
If quick circulation of cooled air is desired, push the air intake
control
button for RECIRCULATED AIR. The indicator light will
come on.
For normal use, it is best to keep the air intake control button
set to the 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 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.
(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
186This button allows the air intake to select the OUTSIDE AIR
mode automatically. This is to clean up the front view more
quickly. If you want to return the setting to the
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) Center vents and side 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
be set to the OUTSIDE AIR mode and the fan speed to any
setting except “OFF”.

Using your audio system: some basics
This section describes some of the basic features of the Lexus
audio system. Some information may not pertain to your
system.
Your audio system adjusts to the optimum volume and tone
quality automatically. While the system is adjusting the audio
sound, the audio sound fades out and then fades in.
Your audio system works when the ignition switch is in the
“ACC” or “ON” position.
NOTICE
To prevent the battery from being discharged, do not
leave the car audio on longer than necessary when the
engine is not running.
(a) Turning the system on and off
Push this knob to turn the audio system on and off. Turn
this knob to adjust the volume.
The system turns on in the last mode used.

AUDIO
198
Push the “AM”, “FM”, “TAPE” or “DISC” button to turn on
that mode. The selected mode turns on directly.
Push these buttons if you want to switch from one mode to
another.
If the tape or disc is not set, the cassette player or compact disc
player does not turn on.
You can turn off the cassette player by ejecting the cassette
tape. If the audio system was previously off, then the entire
audio system will be turned off when you eject the cassette
tape. If another function was previously playing, it will come on
again.In the “TAPE” or “CD” mode, the applicable functions are
shown in the lowest part of the display. Push the switch
just below to turn on each function.
(b) Tone and balance
How good an audio program sounds to you is largely
determined by the mix of the treble, mid −range, and bass
levels. In fact, different kinds of music and vocal programs
usually sound better with different mixes of treble, mid −range
and bass.
A good balance of the left and right stereo channels and of the
front and rear sound levels is also important.
Keep in mind that if you are listening to a stereo recording or
broadcast, changing the right/left balance will increase the
volume of one group of sounds while decreasing the volume
of another.
