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.

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.

Use high−
quality cassettes:
 Low−quality cassette tapes can cause many problems,
including poor sound, inconsistent playing speed, and
constant auto−reversing. They can also get stuck or tangled
in the cassette player.
 Do not use a cassette if it has been damaged or tangled or
if its label is peeling off.
 Do not leave a cassette in the player if you are not listening
to it, especially if it is hot outside.
 Store cassettes in their cases and out of direct sunlight.
 Avoid using cassettes with a total playing time longer than
100 minutes (50 minutes per side). The tape used in these
cassettes is thin and could get stuck or tangled in the
cassette player. Caring for your compact disc player and discs

Your compact disc player is intended for use with 12 cm (4.7
in.) discs only.
 Extremely high temperature can keep your compact disc
player from working. On hot days, use air conditioning to
cool the vehicle interior before you listen to a disc.
 Bumpy roads or other vibrations may make your compact
disc player skip.
 If moisture gets into your compact disc player, you may not
hear any sound even though your compact disc player
appears to be working. Eject all discs from the player and
wait until the player dries.
CAUTION
Compact disc players use an invisible laser beam which
could cause hazardous radiation exposure if directed
outside the unit. Be sure to operate the player correctly.

shiny side.
 Dirt, scrapes, warping, pin holes, or other disc damage
could cause the player to skip or to repeat a section of a
track. (To see a pin hole, hold the disc up to the light.)
