INSIDE REAR VIEW MIRROR
16X016e
Adjust the mirror so that you can just see the rear of your
vehicle in the mirror.
Pushing the switch changes the mode between “AUTO”
and “DAY”.
The indicator comes on when the “AUTO” mode is selected.
“DAY” mode: The mirror surface is normal.
“AUTO” mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror surface
darkens slightly to reduce the reflected light.
When the inside rear view mirror surface changes, the outside
rear view mirror surfaces will also become darker.
When the ignition key is inserted and turned on, the inside rear
view mirror always turns on in the “AUTO” mode. When
the inside air temperature is low, it may take a little longer
for the mirror to darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in death or serious
injuries.
16x658b
To ensure correct functioning of antiglare mirror sensors
located on both sides of the mirror, do not touch or cover
the sensors with your finger or a piece of cloth, etc.

If manual switching of air intake is desired
20X023a
Each time you push the air intake control button, the mode
changes in order from the RECIRCULATED AIR mode to
AUTOMATIC mode to OUTSIDE AIR mode, then back to the
RECIRCULATED
AIR mode. Each indicator light shows which
mode is now selected.
1 RECIRCULATED mode If quick circulation of cooled air
is desired, select this mode.
2 EXHAUST GAS AUTOMATIC mode If the outside air
contains harmful substances like exhaust gas (i.e., when
the vehicle running just in front of your vehicle accelerates
rapidly), the system changes automatically from the
OUTSIDE AIR mode (with indicators
2
and 3 on) to
the RECIRCULATED mode (with indicators 1
and 2
on).
3 OUTSIDE AIR mode The system will take fresh outside
air into the vehicle. Turning off the air conditioning manually will cancel the
EXHAUST
GAS AUTOMATIC mode. If you select the “AUTO”
mode during fan operating, the air conditioning turns on and
the EXHAUST GAS AUTOMATIC mode will operate.
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.
In the following cases, the RECIRCULATED mode may
change to the OUTSIDE AIR mode automatically to prevent
interior fog.
 When the outside temperature becomes lower than 4 C
(39 F).
 When the air conditioning compressor malfunctions.
 When the air conditioning cooler refrigerant decreases.
To change the sensitivity of the sensor switching between
the RECIRCULA TED and OUTSIDE AIR in the AUTOMATIC
mode, push the air intake control button until the “AUTO”
indicator light flashes. The display changes as illustrated
below.
The sensitivity of the sensor can be adjusted only while the
vehicle has stopped.

When you turn the “TEMP” knob, the sensitivity changes from
“+3” down to “−3”. If you do not operate any button for a few
seconds or if you push a button other than the air intake control
button and temperature control knob, the previous display
returns.
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. If you turn off the air
conditioning manually, the EXHAUST GAS AUTOMATIC
mode will be cancelled.
If the outside temperature is lowered down to around 0 C
(32 F), the air conditioning will turn off automatically. At this
time, the indicator on the A/C button is off and the EXHAUST
GAS AUTOMATIC indicator light remains on. However, the
EXHAUST GAS AUTOMA TIC mode does not operate. When
the air conditioning turns on as with the raised temperature, the
EXHAUST GAS AUTOMATIC mode resumes. 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.

AIR CONDITIONING

20X073c
Your vehicle is equipped with an air conditioning filter.
The air conditioning filter may clog after long use and
reduce the air flow quantity.
To maintain the air conditioning efficiency, inspect and replace
the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, such
as inner city or desert areas, early replacement may be
required. (For scheduled maintenance information, please
refer to the “Owner’s Manual Supplement / Scheduled
Maintenance”.)
(e) Operating tips
 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”, “Side vents” and “Lower vent”.)\
 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.
 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.
 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.

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.

MID: Adjusts mid− pitched tones.
TRE: Adjusts high− pitched tones.
FAD: Adjusts the sound balance between the front and rear
speakers.
BAL: Adjusts the sound balance between the right and left
speakers.
ASL: Turns on or off the automatic sound levelizer.
Automatic Sound Levelizer (ASL): When the audio sound
becomes difficult to be heard due to road noise, wind noise,
etc. during driving, the system adjusts to the optimum volume
and tone quality according to the noise level. While the
Automatic Sound Levelizer (ASL) is on, “ASL” appears on the
display.
