NOTICE
■To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the engine or other
components does not occur.
●Water entering the engine air
intake will cause severe engine
damage.
●Water entering the automatic
transmission will cause deterio-
ration in shift quality, locking up
of your transmission accompa-
nied by vibration, and ultimately
damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tial, transmission and transfer
case, reducing the gear oil’s
lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated in bra ke drums and
around brake di scs may affect
braking efficiency and may
damage brake system compo-
nents.
●Always perform a maintenance
inspection aft er each day of
off-road driving that has taken
you through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.

■Recharging function
 If a certain amount of time has
elapsed since charging com-
pleted and the portable device
has not been moved, the
wireless charger will restart
charging.
 If a portable device is moved
significantly within the
charging area, the charging
coil may disconnect and
charging may temporarily be
stopped. However, if a
charging coil is detected
within the charging area, the
charging coil inside the wire-
less charger will move near
the other coil and charging
will resume.

3706-1. Maintenance and care
6-1.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.
■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. 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.
■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.
■When using a car wash
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 correction pro-
cedures to wash the vehicle:
●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 bat-
tery-saving mode to disable the
smart key system. ( P.132)
■Wheels and wheel ornaments
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the
wheels when they are hot, such
as after driving or parking in hot
weather
■Brake pads and calipers
Rust may form if the vehicle is
parked with wet brake pads or disc
rotors, causing them to stick. Before
parking the vehicle after it is
washed, drive slo wly and apply the

parts.
■Bumpers
Do not scrub with abrasive cleaners.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●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 ra indrop 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 equipped)
If the paint of th e rear bumper is
chipped or scratched, the system
may malfunction. If this occurs,
consult your Toyota dealer.
NOTICE

tion and corrosion on the
body and components (alumi-
num wheels, etc.)
●Wash the vehicle immediately in
the following cases:
• After driving nea r the sea coast

3726-1. Maintenance and care
NOTICE
• After driving in an area contami-nated with soot, oily smoke,
mine dust, iron powder or chem-
ical substances
• 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 came ra 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, s uch 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.
