These
are the controls added to the front air conditioning when
your vehicle is equipped with a rear air conditioning. The
controls for the rear passengers and for the front passengers
both work the same, so operation can be made with the
controls on either panel.
(a) Controls and Functions
This rear air conditioning is equipped with dustproof and
deodorant filter with photocatalyst. When light in the
xenon tube (ultraviolet rays) hits the filter, odious
ingredients adsorbed in the filter are oxidized and
decomposed to deliver clean air in the interior.

turn on if the front air conditioning is off.

When you install the filter, face the filter surface (gray)
downward and fit the filter folds properly in the case as shown.

because of ultraviolet rays included in the light, however it is
no problem for use.

AIR CONDITIONING
257
When the ignition switch is turned on, the xenon tube comes
on even if the rear air conditioning or rear fan is not operating.
This
does not indicate a malfunction but is required for the long
use of the photocatalyst.
NOTICE
 Do not look into the xenon tube in the air purifier
through the filter slot and do not expose your skin
directly to the light in the xenon tube also. Although
the xenon tube scarcely issues less than 300nm
ultraviolet rays which are thought harmful for the
human body, some people may have symptoms such
as eye sore, vision trouble, skin inflammation, etc.
 Do not disassemble the air purifier , or it may cause a
malfunction. As some part in the purifier is under
high voltage, you may get an electric shock when you
touch it.
 The filters should be installed properly in position.
The use of rear air conditioning controls with the filter
removed may cause the malfunction of the rear air
conditioning controls.
 Turn on the air conditioning with a filter in position.
The activation without an filter may not only cause a
malfunction of the system but also dirty the interior
by spouting dust.

Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to
serious engine trouble due to insufficient oil.
For detailed information on oil level check, see “Checking the
engine oil level” described below.
