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.

■

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 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

• 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.

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

●

Make sure that the “ACCES-

SORY” or “IGNITION ON” on 

the multi-information display 

and the “READY” indicator are 

both off.

●

Keep hands, clothing and tools 

away from the moving fans.

Items

Parts and tools

●

Be careful not to touch the 

engine, power control unit, radi-

ator, exhaust manifold, etc. right 

after 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 12-volt battery. Fuel and 

12-volt battery fumes are flam-

mable.

●

Be extremely cautious when 

working on the 12-volt battery. It 

contains poisonous and corro-

sive sulfuric acid.

■

When working near the elec-

tric cooling fans or radiator 

grille

Be sure the power switch is OFF.

With the power switch in ON, the 

electric cooling fans may auto-

matically start to run if the air con-

ditioning is on and/or the coolant 

temperature is high. (

■

When adding washer fluid

Do not add washer fluid when the 

hybrid system is hot or operating 

as washer fluid contains alcohol 

and may catch fire if spilled on the 

engine, etc.

NOTICE

■

Do not use any fluid other 

than washer fluid

Do not use soapy water or engine 

antifreeze instead of washer fluid.

Doing so may cause streaking on 

the vehicle’s painted surfaces, as 

well as damaging the pump lead-

ing to problems of the washer 

fluid not spraying.

■

Diluting washer fluid

Dilute washer fluid with water as 

necessary.

Refer to the freezing tempera-

tures listed on the label of the 

washer fluid bottle.

■

When to replace your vehicle’s 

tires

Tires should be replaced if:

●

The treadwear indicators are 

showing on a tire

●

You have tire damage such as 

cuts, splits, cracks deep enough 

to expose the fabric, and bulges 

indicating internal damage

●

A tire goes flat repeatedly or can-

not be properly repaired due to the 

size or location of a cut or other 

damage

If you are not sure, consult with your 

Toyota dealer.

■

Tire life

Any tire over 6 years old must be 

checked by a qualified technician 

even if it has seldom or never been 

used or damage is not obvious.

■

Maximum load of tire

Check that the maximum load of the 

replacement tire is greater than 1/2 

of the Gross Axle Weight Ratings 

(GAWR) of either the front axle or 

the rear axle, whichever is greater.
For the GAWR, see the Certification 

Label.

For the maximum load of the tire, 

see the load limit at maximum cold 

tire inflation pressure mentioned on 

the sidewall of the tire. (

Tire types

●

Summer tires

Summer tires are high-speed perfor-
mance tires best suited to highway 
driving under dry conditions. Since 
summer tires do not have the same 
traction performance as snow tires, 
summer tires are inadequate for 
driving on snow-covered or icy 
roads. For driving on snow-covered 
roads or icy roads, the use of snow 
tires is recommended. When install-
ing snow tires, be sure to replace all 
four tires.

●

All season tires

All season tires are designed to pro-
vide better traction in snow and to 
be adequate for driving in most win-
ter conditions as well as for use 
year-round. All season tires, how-
ever, do not have adequate traction 
performance compared with snow 
tires in heavy or loose snow. Also, 
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway 
driving.

●

Snow tires

For driving on snow-covered roads 
or icy roads, we recommend using 
snow tires. If you need snow tires, 
select tires of the same size, con-
struction and load capacity as the 
originally installed tires. Since your 
vehicle has radial tires as original 
equipment, make sure your snow 
tires also have radial construction. 
Do not install studded tires without 
first checking local regulations for 
possible restrictions. Snow tires 
should be installed on all wheels. 
(

P.247)

■

If the tread on snow tires wears 

down below 0.16 in. (4 mm)

The effectiveness of the tires as 

snow tires is lost.

Checking the tire valves

When replacing the tires, check the 

tire valves for deformation, cracks, 

and other damage.

Rotate the tires in the order 
shown.

Front

To equalize tire wear and extend 
tire life, Toyota recommends that 
tire rotation is carried out at the 
same interval as tire inspection.
Vehicles with a tire pressure warn-
ing system: Do not fail to initialize 
the tire pressure warning system 
after tire rotation.

Your vehicle is equipped with a 
tire pressure warning system 
that uses tire pressure warning

WARNING

■

When inspecting or replacing 

tires

Observe the following precautions 

to prevent accidents.

Failure to do so may cause dam-

age to parts of the drive train as 

well as dangerous handling char-

acteristics, which may lead to an 

accident resulting in death or seri-

ous injury.

●

Do not mix tires of different 

makes, models or tread pat-

terns.

Also, do not mix tires of remark-

ably different treadwear.

●

Do not use tire sizes other than 

those recommended by Toyota.

●

Do not mix differently con-

structed tires (radial, bias-belted 

or bias-ply tires).

●

Do not mix summer, all season 

and snow tires.

●

Do not use tires that have been 

used on another vehicle.

Do not use tires if you do not 

know how they were used previ-

ously.

NOTICE

■

If tire inflation pressure of 

each tire becomes low while 

driving

Do not continue driving, or your 

tires and/or wheels may be 

ruined.

■

Driving on rough roads

Take particular care when driving 

on roads with loose surfaces or 

potholes.

These conditions may cause 

losses in tire inflation pressure, 

reducing the cushioning ability of 

the tires. In addition, driving on 

rough roads may cause damage 

to the tires themselves, as well as

Situations in which the tire 

pressure warning system may 

not operate properly

●

In the following cases, the tire 

pressure warning system may not 

operate properly.

• If non-genuine Toyota wheels are 

used.

• A tire has been replaced with a 

tire that is not an OE (Original 

Equipment) tire.

• A tire has been replaced with a 

tire that is not of the specified size.

• Tire chains, etc. are equipped.

• An auxiliary-supported run-flat tire 

is equipped.

• If a window tint that affects the 

radio wave signals is installed.

• If there is a lot of snow or ice on 

the vehicle, particularly around the 

wheels or wheel housings.

• If the tire inflation pressure is 

extremely higher than the speci-

fied level.

• If tires not equipped with tire pres-

sure warning valves and transmit-

ters are used.

• If the ID code on the tire pressure 

warning valves and transmitters is 

not registered in the tire pressure 

warning computer.

●

Performance may be affected in 

the following situations.

• Near a TV tower, electric power 

plant, gas station, radio station, 

large display, airport 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.

●

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.

■

Warning performance of the tire

■

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 than 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 vehi-

cle 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

When replacing wheels

●

Do not use wheels that are a dif-

ferent size from those recom-

mended in the Owner’s Manual, 

as this may result in a loss of 

handling control.

Doing so may result in an acci-

dent, causing death or serious 

injury.

■

When installing the wheel 

nuts

Never use oil or grease on the 

wheel bolts or wheel nuts.

Oil and grease may cause the 

wheel nuts to be excessively tight-

ened, leading to bolt or disc wheel 

damage. In addition, the oil or 

grease can cause the wheel nuts 

to loosen and the wheel may fall 

off, causing an accident and 

resulting in death or serious injury. 

Remove any oil or grease from 

the wheel bolts or wheel nuts.

■

Use of defective wheels pro-

hibited

Do not use cracked or deformed 

wheels. Doing so could cause the 

tire to leak air during driving, pos-

sibly causing an accident.

Scheduled maintenance of the 

air intake vent is necessary 

when

In some situations such as when the 

vehicle is used frequently or in 

heavy traffic or dusty areas, the air 

intake vent may need to be cleaned 

more regularly. For details, refer to 

“Scheduled Maintenance Guide” or 

“Owner’s Manual Supplement”.

■

Cleaning the air intake vent

●

Dust in the air intake vent may 

interfere with the cooling of the 

hybrid battery (traction battery). If 

charging/discharging of the hybrid 

battery (traction battery) becomes 

limited, the distance that the vehi-

cle can be driven using the electric 

motor (traction motor) may be 

reduced and the fuel economy 

may be reduced.

Inspect and clean the air intake 

vent periodically.

●

Improper handling of the air intake 

vent cover and filter may result in 

damage to them. If you have any 

concerns about cleaning the filter, 

contact your Toyota dealer.
