●To let fresh air in, set the air condition-
ing system to the outside air mode.
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condi-tioning system be set to outside air
mode prior to 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.

WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch 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 outside rear view mirror surfaces, as they can become very hot and burn you.
●Vehicles with windshield wiper de-icer: Do not touch the glass at lower
part of the windshield or to the side of the front pillars when the wind-shield wiper de-icer is on.

ronment, signals from the wireless switch may transmit further than expected. Pay appropriate attention

lukewarm water as soon as possible.
●If the windows are very dirty, do not
open and close them repeatedly.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the
vehicle. Doing so may cause the electrical components, etc., to malfunction or
catch fire.
●Do not get any of the SRS compo-
nents or wiring in the vehicle interior wet. ( P. 3 9 ) An electrical malfunction may
cause the airbags to deploy or not function properly, resulting in death or serious injury.
●Vehicles with wireless charger: Do not let the wireless charger
( P.446) get wet. Failure to do so may cause the charger to become hot and cause burns or could cause
electric shock resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use a polish wax or polish
cleaner. The instrument panel may reflect off the windshield, obstructing the driver’s view and leading to an
accident, resulting in death or serious injury.
NOTICE
■Cleaning detergents
●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 sub- stances such as benzene or gaso-line, alkaline or acidic solutions,

hol
●Do not use a polish wax or polish
cleaner. The instrument panel’s or other interior part’s painted surface may be damaged.
■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 sys-tem above or under the floor of the
vehicle. Water may also cause the body to rust.
■When cleaning the inside of the windshield
Do not allow glass cleaner to contact
the lens. Also, do not touch the lens. ( P.276)
■Cleaning the inside of the rear window
●Do not use a glass cleaner to clean
the rear window, as this may cause damage to the rear window defog-ger heater wires or antenna. Use a
cloth dampened with lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.

vacuum cleaner.
 Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent.
Use a diluted water solution of
approximately 5% neutral wool
detergent.
 Wring out any excess water from
the cloth and thoroughly wipe off
all remaining traces of detergent.
 Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
Allow the leather to dry in a
shaded and ventilated area.
■Caring for leather areas
Toyota recommends cleaning the inte- rior of the vehicle at least twice a year to maintain the quality of the vehicle’s inte-
rior.
 Remove dirt and dust using a
vacuum cleaner.
 Wipe it off with a soft cloth damp-
ened with neutral detergent
diluted to approximately 1%.
 Wring out any excess water from
the cloth and thoroughly wipe off
NOTICE
