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”.

surface facing down. Depending
on the portable device, its
charging coil may not be in the
center of the device. In this
case, place the portable device
so that its charging coil is cen-
tered in the charging area.
While charging, the operation indi-
cator light (oran ge) will be illumi-
nated.
If charging does not begin, move

nal devices
●Do not leave external devices in
the vehicle. The temperature
inside the vehicle may become
high, resulting in damage to an
external device.
●Do not push down on or apply
unnecessary force to an exter-
nal device or the cable of an
external device while it is con-
nected.

■The wireless charger can be
operated when
The engine switch is in ACC or ON.
■Portable devices that can be
charged
●Portable devices compatible with
the Qi wireless charging standard
can be charged by the wireless
charger. However, compatibility
with all devices which meet the Qi
wireless charging standard is not
guaranteed.
●The wireless charger is designed
to supply low power electricity (5
W or less) to a cellular phone,
smartphone, or other portable
device.
●Failure to do so may result in the
possibility of fire, However, porta- ble devices, such as the following,
can be charged with more than 5
W.
• 7.5 W charging compatible iPhones can be charged at 7.5 W
or less.
• Portable devices which conform to WPC Ver 1.2.4 (Extended Power
profile ) can be charged at 10 W or
less.
■If a cover or accessory is
attached to the portable device
Do not charge a portable device if a
cover or accessory w hich is not Qi
compatible is atta ched. Depending
on the type of cover (including for
certain genuine manufacturer parts)
and/or accessory a ttached, it may
not be possible to charge the porta-
ble device. If the portable device is

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
■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 nea r 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

■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 ser-
vice information. They are well
informed about the operation 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”.
Maintenance require-
ments
To ensure safe and econom-
ical driving, day-to-day care
and regular maintenance
are essential. It is the
owner’s responsibility to
perform regular checks.
Toyota recommends the fol-
lowing maintenance:
WARNING
■If your vehicle is not properly
maintained
Improper maintenance could
result in serious damage to the
vehicle and possible death or seri-
ous injury.
■Handling of the battery
●Engine exhaust, some of its
constituents, and a wide variety
of automobile components con-
tain or emit chemicals known to
the State of California to cause
cancer and birth defects and
other reproductive harm. Work
in a well ventilated area.
●Oils, fuels and fluids contained
in vehicles as well as waste pro-
duced by component wear con-
tain or emit chemicals known to
the State of California to cause
cancer and birth defects or
other reproductive harm. Avoid
exposure and wash any
affected area immediately.
●Battery posts, terminals and
related accessories contain lead
and lead compounds which are
known to cause brain damage.
Wash your hands after han-
dling. ( P.391)

WARNING
The engine 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 engine
compartment
●Keep hands, clothing and tools
away from the moving fan and
engine drive belt.
ItemsParts and tools●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter driving as
they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.390)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.
