(c) Micro dust and pollen filter
This vehicle is equipped with a micro dust and pollen filter
mode. When this mode is activated, air from the vents will
remove pollen on the driver and passengers.
G21073
Push the micro dust and pollen filter button.
The indicator light and “A/C” switch come on and
RECIRCULATED AIR mode is turned on. Air is delivered from
the instrument panel vents to the areas near the driver and
passengers to remove pollen on them.
When the interior is purified sufficiently with fresh air (after
about 3 minutes at normal outside temperature and about 1
minute at low outside temperature), this mode will be turned off
automatically and the indicator light will go out.
When the micro dust and pollen filter is activated, this mode will
be turned off by pushing the micro dust and pollen filter button
again. The indicator light will also go out.
INFORMATION
 Use this mode to remove pollen quickly carried by the
driver or passengers or through the window in the
days with much pollen.
 Use and push the windshield air flow button to
remove the fog on the windshield in rainy days.
 Fresh air is delivered even when the micro dust and
pollen filter button is turned off.

(f) Replacing the air conditioning filter
G21011
The air conditioning filter information label is placed in the
glove box as shown and indicates that a filter has been
installed.
The air conditioning filter, in addition to removing odors,
prevents dust and pollen from entering the vehicle through the
air conditioning vent.

G21012
The air conditioning filter is behind the glove box.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioning
and heater experiences extreme reductions in operating
efficiency, or if the windows fog up easily.
If the symptoms of air conditioning efficiency problems occur,
contact your nearest Lexus dealer to have the filter replaced.
To maintain the air conditioning efficiency, replace the air
conditioning filter according to the maintenance schedule. In
dusty areas or areas with heavy traffic flow, such as inner city
or desert areas, early replacement may be required. (For
scheduled maintenance information, see the “Owner’s Manual
Supplement / Scheduled Maintenance”). 1. Turn the air intake control to RECIRCULATED AIR
mode.
The filter case cannot be removed in the OUTSIDE AIR mode.
2. Turn off the engine switch.
3. When you replace the filter, be sure to turn off the fan.G21013

NOTICE
When setting the filter to the filter case, the UP marks
shown on the filter and filter case should be noted and
fitted as shown.
INFORMATION
The air conditioning filter should be installed properly
in position. The use of air conditioning with the filter
removed may cause deteriorated dustproof perfor-
mance and then affect air conditioning performance.

Fuel
filler door: Do not apply water (high −pressure car wash,
for example) at or near the fuel tank inlet with the fuel filler door
opened. If the water enters the air vent, you may experience
trouble with refueling or rough engine idling.
Plastic wheel ornaments: The plastic wheel ornaments are
damaged easily by organic substances. If any organic
substances splash an ornament, be sure to wash them of f with
water and check if the ornament is damaged.
Aluminum wheels: Use only a mild soap or neutral detergent.
Plastic bumpers and side moldings: Wash carefully. Do not
scrub with abrasive cleaners. The bumper and side molding
faces are soft.
Exterior lights: Wash carefully. Do not use organic
substances or scrub them with a hard brush. This may
damage the surfaces of the lights.
Road tar: Remove with turpentine or cleaners that are marked
safe for painted surfaces.
3. Rinse thoroughly − dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard − you might scratch the
paint.
NOTICE
 Do not use organic substances (gasoline, kerosene,
benzine or strong solvents), which may be toxic or
cause damage.
 Do not scrub any part of the vehicle with a hard brush,
which may cause damage.
Automatic car wash
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some types of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss, especially
on darker colors. The manager of the car wash should be able
to advise you whether the process is safe for the paint on your
vehicle.
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus’ finish.
Apply wax once a month or if the vehicle surface does not repel
water well.
1. Always wash and dry the vehicle surface before you begin
waxing, even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become
extremely weathered, use a car−cleaning polish, followed by
a separate wax. Carefully follow the manufacturer’s
instructions and precautions. Be sure to polish and wax the
chrome trim as well as the paint.
