Maintenance and care
 Remove dirt and dust using a
vacuum cleaner. Wipe dirty
surfaces with a cloth damp-
ened with lukewarm water.
 If dirt cannot be removed,
wipe it off with a soft cloth
dampened with neutral deter-
gent diluted to approximately
1%.
Wring out any excess water
from the cloth and thoroughly
wipe off remaining traces of
detergent and water.
■Shampooing the carpets
There are several commercial foam-
ing-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.
■Handling the seat belts
Clean with mild soap and lukewarm
water using a cloth or sponge. Also
check the belts periodically for
excessive wear, fraying or cuts.
■Front side window s with IR pro-
tective coating
The front side windows have IR pro-
tective coating. To prevent any dam-

• 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 con-
tinuously 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 usin g a high pres-
sure car washer. If water enters
the traction battery, the EV sys-
tem may malfunction.
●Do not use the washer on the
area around the charging port
lid. Water could get into the
charging inlet and could dam-
age the vehicle.
■Cleaning aluminum parts
When cleaning the hood, do not
push hard or put weight on it.
The aluminum part may be
dented.
Cleaning and protect-
ing the vehicle interior
Perform cleaning in a man-
ner appropriate to each
component and its material.

●Performance may be affected in
the following situations.
• Near a TV tower, electric power
plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device
If tire position information is not cor-
rectly displayed due to the radio
wave conditions, the display may be
corrected by driving and changing
the radio wave conditions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure warn-
ing computer and the tire pressure
warning system must be initialized.
(  P.481)
■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, the tire pressure warning
system will not work properly. After driving for about 10 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

warning valves and trans-
mitters
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your
Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves and the tire pressure
warning valves could be bound.
●When replacing tire valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repa ired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer as soon as possible. After
use of liquid sealant, make sure to
replace the tire p ressure warning
valve and transmitter when repair-
ing or replacing the tire.

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result in the following:
●Reduced electricity consumption
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
●Check only when the tires are
cold.
If your vehicle has been parked for
at least 3 hours or has not been
driven for more tha n 1 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is
properly inflated based only on its
appearance.
●It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
●Never exceed the vehicle capacity
weight. Passengers and luggage
weight should be placed so that
the vehicle is balanced.
WARNING
■Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting
from overheated tires
●Air leaking from between tire
and wheel
●Wheel deformation and/or tire
damage
●Greater possibi lity of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing tire inflation pressure
Be sure to put the tire valve caps
back on.
If a valve cap is no t installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.

Use only Toyota wheel bolts
and wrenches designed for
use with your aluminum
wheels.
 When rotating, repairing or
changing your tires, check
that the wheel bolts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels. 1
Turn the power switch off.
Confirm that the charging connec-
tor is not connected. Also, do not
use the Remote Air Conditioning
System during the procedure.
2Open the front passenger’s
door.
By keeping the door open, unex-
pected operation of the Remote Air
Conditioning System can be pre-
vent. ( P.409)
3 While pressing the claw, hold
handle and remove the
panel.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.

■When installing the filter cover
Slide the recessed part of the fil-
ter cover on the upper surface of the
upper filter case as shown in the
figure, and attach it so that it is lifted
toward the insertion part of the
cover attachment.
■Checking interval
Inspect and replace the air condi-
tioning filter according to the mainte-
nance schedule. In dusty areas or
areas with heavy traffic flow, early
replacement may be required. (For
scheduled maintenance information,
please refer to the “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
■If air flow from the vents
decreases dramatically
The filter may be clogged. Check
the filter and replace if necessary.
WARNING
■When replacing the air condi-
tioning filter
Observe the following precau-
tions. Failure to do so may result
in the air conditioning system
operating during the procedure,
possibly resulting in injury.
●Check that the charging con-
nector is not connected
●Do not use the Remote Air Con-
ditioning System
NOTICE
■When using the air condition-
ing system
●Make sure that a filter is always
installed. Using the air condi-
tioning system without a filter
may cause damage to the sys-
tem.
●The filter is replaceable. When
cleaning the filter, do not clean
with water or an air gun.
■To prevent damage to the fil-
ter cover
When moving the filter cover in
the direction of arrow to release
the fitting, pay attention not to
apply excessive force to the
claws. Otherwise, the claws may
be damaged.
