■

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

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.

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 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.

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.

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

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.

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 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

●

Poor handling

●

Possibility of blowouts resulting

from overheated tires

●

Air leaking from between tire

and wheel

●

Wheel deformation and/or tire

damage

When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset

*

.

Replacement wheels are avail-
able at your Toyota dealer.

*

: Conventionally referred to as off-

set.

Toyota does not recommend
using the following:



Wheels of different sizes or
types



Used wheels



Bent wheels that have been
straightened

■

When replacing wheels (vehi-

cles with a tire pressure warn-

ing system)

The wheels of your vehicle are

equipped with tire pressure warning

valves and transmitters that allow

the tire pressure warning system to

provide advance warning in the

event of a loss in tire inflation pres-

sure. Whenever wheels are

replaced, the tire pressure warning

valves and transmitters must be

installed. (



P.446)

WARNING

●

Greater possibility 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 not installed, dirt

or moisture may get into the valve

and cause an air leak, resulting in

decreased tire inflation pressure.

Wheels

If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.



Use only Toyota wheel nuts
and wheel nut wrenches
designed for use with your
aluminum wheels.



When rotating, repairing or
changing your tires, check
that the wheel nuts 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.

WARNING

■

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.

●

Never use an inner tube in a

leaking wheel which is designed

for a tubeless tire.

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.

NOTICE

■

Replacing tire pressure warn-

ing valves and transmitters

(vehicles with a tire pressure

warning system)

●

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.
