Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.
CALIBRATING THE COMPASS (circling calibration)
16x280a
“C” appears on the display in case the circling calibration is
required due to a drastic change in the magnetic field. To
rectify this, follow the calibration procedure below.
16x270
Drive the vehicle slowly (at 8 km/h (5 mph) or lower) in a circle
until the direction is displayed. If there is not enough space to
drive in a circle, drive around the block until the direction is
displayed.
After driving in 1 to 3 circles in the above method, calibration
is complete with the direction shown on the display.
If calibration cannot be performed because of the magnetized
vehicle, etc., take your vehicle to Lexus dealer.
 Do not perform circling calibration of the compass in a place
where the earth’s magnetic field is subject to interference by
artificial magnetic fields (underground parking, under a
steel tower, between buildings, roof parking, near a
crossing, near a large vehicle, etc.).
 During calibration, do not operate electric systems (moon
roof, power windows, etc.) as they may interfere with the
calibration.

CAUTION
When doing the circling calibration, be sure to secure
a wide space, and watch out for people and vehicles
in the neighborhood. Do not violate any local traffic
rules while performing circling calibration.
 Do not adjust the display while the vehicle is moving.
Be sure to adjust the display only when the vehicle is
stopped.

You can adjust the brightness of the display. See
“Instrument panel light control” on page 66 for details.
The automatic air conditioning automatically maintains
the set temperature.
This air conditioning features automatic fan speed and air flow
control which automatically se lects the most suitable fan
speed and air flow to control the temperature. The ignition key
must be in the “ON” position.NOTICE
To prevent the battery from being discharged, do not
leave the air conditioning on longer than necessary
when the engine is not running.

1. Push the “AUTO” button.
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 mode relevant to the
depressed button is set. Other conditions continue to be
adjusted automatically.
It is recommended that you close the lower vent. For details
about this, see page 212.
Push the “OFF” button to turn the air conditioning off.

2. Turn the “TEMP” knob until the desired temperature is
displayed.
The “TEMP” knob 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 or Centigrade.

When one of the manual control buttons is depressed
while operating in automatic mode, the mode relevant to
the depressed button is set. Other conditions continue to
be adjusted automatically.
If manual air flow selection is desired
20X021a
The outlets from which air is delivered can be selected
manually by pressing the button. The function of each mode
is as follows:
1
Panel − Air flows mainly from the instrument panel vents.
2
Bilevel − Air flows from both the floor vents and the
instrument panel vents.
3 Floor − Air flows mainly from the floor vents.
It is recommended that you close the lower vent. For details
about this, see page 212.
4 Floor/Windshield − Air flows mainly from the floor vents
and windshield vents.
It is recommended that you close the lower vent. For details
about this, see page 212.
If quick heating or cooling is desired
Turn the “TEMP” knob until “MAX. HOT” or “MAX. COLD”
appears on the display.
If manual fan speed control is desired
21x600
 1 Fan speed at low 2Fan 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
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.
