7-1.Maintenance and care
Working from top to bottom,
liberally apply water to the
vehicle body, wheel wells and
underside of the vehicle to
remove any dirt and dust.
 Wash the vehicle body using
a sponge or soft cloth, such
as a chamois.
 For hard-to-remove marks,
use car wash soap and rinse
thoroughly with water.
 Wipe away any water.
 Wax the vehicle when the
waterproof coating deterio-
rates.
If water does not bead on a clean
surface, apply wax when the vehi-
cle body is cool.
■Self-restoring coat
The vehicle body has a self-restor-
ing coating that is resistant to small
surface scratches caused in a car
wash, etc.
●The coating lasts for 5 to 8 years
from when the vehicle is delivered
from the plant.
●The restoration time differs
depending on t he depth of the scratch and outside temperature.
The restoration time may become
shorter when the coating is
warmed by applying warm water.
●Deep scratches caused by keys,
coins, etc., cannot be restored.
●Do not use wax that contain abra-
sives.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors
• Turn off the power back door (if equipped)
Start washing from the front of the
vehicle. Make sure to extend the
mirrors before driving.
●Brushes used in automatic car
washes may scratch the vehicle
surface, parts (wheel, etc.) and
harm your vehicle’s paint.
●Rear spoiler may not be washable
in some automatic car washes.
There may also be an increased
risk of damage to vehicle.
●When the shift position needs to
be held in N, refer to P.239.
■High pressure car washes
As water may enter the cabin, do
not bring the nozzle tip near the
gaps around the doors or perimeter
of the windows, or spray these
areas continuously.
■Note for a smart key system
●If the door handle becomes wet
while the electronic key is within
the effective range, the door may
lock and unlock repeatedly. In that
case, follow the following correc-
tion procedures to wash the vehi-
cle:
• Place the key in a position 6 ft. (2 m) or more separate from the
vehicle while the vehicle is being
washed. (Take care to ensure that
the key is not stolen.)
• Set the electronic key to battery-
saving mode to disable the smart
key system. ( P.188)

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 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.

■Repair and replacement
It is recommended that genuine
Toyota parts be used for repairs to
ensure performanc e 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 service
information. They are well
informed about the operations of
all systems on your vehicle.
●Keep a copy of the repair order. It
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”.
You can perform some mainte-
nance procedures by yourself.

that a problem exists some-
where in the emission control
system. Your vehicle may not
pass the I/M test and may need
to be repaired. Contact your

connected or discharged
Readiness codes that are set
during ordinary driving are
erased.
Also, depending on your driving
habits, the readiness codes may
not be completely set. The error code in the OBD sys-
tem will not be cleared unless
the vehicle is driven 40 or more
times.
Contact your Toyota dealer to
prepare the vehicle for re-test-
ing.

The motor compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the motor
compartment
●Make sure that “POWER ON”
on the multi-information display
and the “READY” indicator are
both off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
motor, power control unit, radia-
tor, etc., right after driving as
they may be hot. Coolant and
other fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the motor compartment.
●Do not smoke, cause sparks or
expose an open flame to the 12-
volt battery. 12-volt battery
fumes are flammable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables and their con-
nectors. It can cause severe
burns or electric shock that may
result in death or serious injury.
