1. Push the ºAUTOº 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 operation
corresponding to the button depressed is set. Other
conditions continue to be adjusted automatically.
Push the ºOFFº button to turn the air conditioning system
off.

The outlets from which air is delivered can be selected
manually by pushing the button. The function of each
mode is as follows:

vents.
2 Bi±level ± Air flows from both the floor vents and
the instrument panel vents.
3 Floor ± Air flows mainly from the floor vents.

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 indicator 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.
If the engine coolant temperature becomes extremely
high, the RECIRCULATED AIR mode is automatically
selected. This is not a malfunction. When the engine
coolant temperature is lowered, the previous mode
resumes.
If manual on±off of the air conditioning is desired ±
Push the ºA/Cº 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 ºA/Cº button will blink. If the indicator of
the ºA/Cº button blinks even when the ºA/Cº button is
pushed again, have the compressor checked by your
nearest Lexus dealer.
Displaying the outside temperature ±
When you push the ºOUTSIDE TEMPº knob, the
temperature display shows the outside temperature. To
return to the display of the current set temperature, push
the knob again. The temperature display ranges from
±30 C (±22 F) up to 50C (122F).

(c) 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 ºSide ventsº.)
 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 ºOFFº 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.

Gasolines quality
In a very few cases, you may experience driveability
problems caused by the particular gasoline that you are
using. If you continue to have unacceptable driveability,
try changing gasoline brands. If that does not rectify
your problem, then consult your Lexus dealer.

FACTS ABOUT ENGINE OIL CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and
cooling the inside of the engine, and plays a major role
in maintaining the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some
engine oil during normal engine operation. The
causes of oil consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston rings and
cylinders. A thin film of oil is left on the cylinder wall
when a piston moves downwards in the cylinder.
High negative pressure generated when the vehicle
is decelerating sucks some of this oil into the
combustion chamber. This oil as well as some part of
the oil film left on the cylinder wall is burned by the
high temperature combustion gases during the
combustion process.
 Oil is also used to lubricate the stems of the intake
valves. Some of this oil is sucked into the combustion
chamber together with the intake air and is burned
along with the fuel. High temperature exhaust gases
also burn the oil used to lubricate the exhaust valve
stems.
