●
Use a soft cloth dampened with an
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.
●
Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●
To remove oily deposits, use alco-
hol wet wipes or a similar product.
WARNING
■
When washing the vehicle
Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■
When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the switch is in “AUTO”, the wip-
ers may operate unexpectedly in
the following situations, and may
result in hands being caught or
other serious injuries and cause
damage to the wiper blades.
Off
AUTO
●
When the upper part of the
windshield where the raindrop
sensor is located is touched by
hand
●
When a wet rag or similar is
held close to the raindrop sen-
sor
●
If something bumps against the
windshield
●
If you directly touch the raindrop
sensor body or if something
bumps into the raindrop sensor
■
Precautions regarding the
exhaust pipe
Exhaust gasses cause the
exhaust pipe to become quite hot.
When washing the vehicle, be
careful not to touch the pipe until it
has cooled sufficiently, as touch-
ing a hot exhaust pipe can cause
burns.
■
Precaution regarding the rear
bumper with Blind Spot Moni-
tor
If the paint of the rear bumper is
chipped or scratched, the system
may malfunction. If this occurs,
consult your Toyota dealer.
NOTICE
■
To prevent paint deteriora-
tion and corrosion on the
body and components (alumi-
num wheels, etc.)
●
Wash the vehicle immediately in
the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present
on the paint surface
• If dead insects, insect droppings
or bird droppings are present on
the paint surface

NOTICE
• If the vehicle becomes heavily
soiled with dust or mud
• If liquids such as benzene and
gasoline are spilled on the paint
surface
●
If the paint is chipped or
scratched, have it repaired
immediately.
●
To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity when storing the wheels.
■
Cleaning the exterior lights
●
Wash carefully. Do not use
organic substances or scrub
with a hard brush.
This may damage the surfaces
of the lights.
●
Do not apply wax to the sur-
faces of the lights.
Wax may cause damage to the
lenses.
■
When using an automatic car
wash (vehicles with
rain-sensing windshield wip-
ers)
Set the wiper switch to the off
position.
If the wiper switch is in “AUTO”,
the wipers may operate and the
wiper blades may be damaged.
■
When using a high pressure
car wash
●
When washing the vehicle, do
not spray the camera or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●
Do not spray water directly on
the radar which is equipped
behind the emblem. Otherwise
it may cause the device to be
damaged.
●
Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), connectors or
the following parts. The parts
may be damaged if they come
into contact with high-pressure
water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●
Keep the cleaning nozzle at
least 11.9 in. (30 cm) away from
the vehicle body. Otherwise
resin section, such as moldings
and bumpers, may be deformed
and damaged.
Also, do not continuously hold the
nozzle in the same place.
●
Do not spray the lower part of
the windshield continuously.
If water enters the air conditioning
system intake located near the
lower part of the windshield, the
air conditioning system may not
operate correctly.
●
Do not wash the underside of
the vehicle using a high pres-
sure car washer.

WARNING
■
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 lug-
gage compartment.
Doing so may cause the hybrid
battery, electrical components,
etc. to malfunction or catch fire.
●
Do not get any of the SRS com-
ponents or wiring in the vehicle
interior wet.
(
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.373) 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 (espe-
cially instrument panel)
Do not use 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 dis-
color the vehicle interior or
cause streaks or damage to
painted surfaces:

Preventing damage to leather
surfaces
Observe the following precautions
to avoid damage to and deteriora-
tion of leather surfaces:
●

leather surfaces immediately.
●
Do not expose the vehicle to
direct sunlight for extended peri-
ods of time. Park the vehicle in
the shade, especially during
summer.

vinyl, plastic, or containing wax
on the upholstery, as they may
stick to the leather surface if the
vehicle interior heats up signifi-
cantly.
■
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 windshield
Do not allow glass cleaner to con-
tact the lens. Also, do not touch
the lens. (
■
Cleaning the inside of the rear
window
●

Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performance of each sys-
tem. If non-Toyota parts are used in
replacement or if a repair shop other
than a Toyota dealer performs
repairs, confirm the warranty cover-
age.
■
Allow inspection and repairs to
be performed by a Toyota
dealer
●
Toyota technicians are
well-trained specialists and are
kept up to date with the latest ser-
vice information. They are well
informed about the operation of all

proves that the maintenance that
has been performed is under war-
ranty coverage. If any problem
should arise while your vehicle is
under warranty, your Toyota
dealer will promptly take care of it.
General maintenance should be
performed on a daily basis. This
can be done by yourself or by a
Toyota dealer.
Scheduled maintenance should
be performed at specified inter-
vals according to the mainte-
nance schedule.
For details about maintenance
items and schedules, refer to the
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.
Maintenance require-
ments

When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is off.
With the power switch in ON, the
electric cooling fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. (
■
Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
