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)
SV16139
ºCº 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.
SV16079
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.

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.

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 ºONº position.
NOTICE
To prevent the battery from being discharged, do not leave the air conditioning on longer than necessarywhen the engine is not running.

1. Set the air flow control dial and the fan speed control
dial to ºAUTOº 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

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 ºOFFº, the fan is

1Fan speed at low 2Fan 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 ºOFFº 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 ind
icator 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 ºAUTOº 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.
