4226-1. Using the air conditioning system
IS300h_EE(OM53D56E)
■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air mode.
●During use, various odors from inside and outside the vehicle may enter into and accu-
mulate in the air conditioning system. This may then cause odor to be emitted from the
vents.
●To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air mode priorto turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately
after the air conditioning system is started in automatic mode.
■Air conditioning filter
→ P. 4 8 6
■Customization
Settings (e.g. A/C Auto switch operation) can be changed.
(Customizable features →P. 5 9 8 )
CAUTION
■To prevent the windshield from fogging up
●Do not use during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can cause
the outer surface of the windshield to fog up, blocking your vision.
■To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mirror defog-
gers are on.
●Do not touch the glass at lower part of the windshield or to the side of the front pillars
when the windshield wiper de-icer is on.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the hybrid sys-
tem is off.
●Do not place anything on the instrument
panel which may cover the air outlets. Other-
wise, air flow may be obstructed, preventing
the windshield defoggers from defogging.

Maintenance and care
IS300h_EE(OM53D56E)
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or brush to
apply the foam. Rub in overlapping circles. Do not use water. Wipe dirty surfaces and let
them dry. Excellent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water us ing a cloth or sponge. Also check the belts
periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the carpet could
be damaged.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid battery
(traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
( → P. 4 4 )
An electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the wind-
shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.

●Do not use the following types of detergent, as they may discolor the vehicle interior
or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline, alkaline oracidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●Do not use polish wax or polish cleaner. The instrument panel’s or other interior part’s
painted surface may be damaged.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces:
●Remove any dust or dirt from leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended periods of time. Park the
vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or containing wax on the upholstery, as they
may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into contact
with electrical components such as the audio system above or under the floor of the
vehicle. Water may also cause the body to rust.
■When cleaning the inside of the windsh ield (vehicles with LDA [Lane Departure
Alert])
Be careful not to touch the camera sensor ( →P. 2 7 0 ) .
If the camera is accidentally scratched or hit, LDA may not operate properly or may
cause a malfunction.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires or antenna. Use a cloth dampened with luke-
warm water to gently wipe the window clean. Wipe the window in strokes running
parallel to the heater wires or antenna.
●Be careful not to scratch or damage the heater wires or antenna.
