Before recharging

When recharging, the 12-volt bat-

tery produces hydrogen gas which

is flammable and explosive. There-

fore, observe the following precau-

tions before recharging:

If recharging with the 12-volt bat-

tery installed on the vehicle, be

sure to disconnect the ground

cable.

Make sure the charger is off when

connecting and disconnecting the

charger cables to the 12-volt bat-

tery.

After recharging/reconnecting

the 12-volt battery

Unlocking the doors using the

smart key system may not be pos-

sible immediately after reconnect-

ing the 12-volt battery. If this

happens, use the wireless remote

control or the mechanical key to

lock/unlock the doors.

Start the hybrid system with the

power switch in ACC. The hybrid

system may not start with the

power switch turned off. However,

the hybrid system will operate nor-

mally from the second attempt.

The power switch mode is

recorded by the vehicle. If the

12-volt battery is reconnected, the

vehicle will return the power

switch mode to the status it was in

before the 12-volt battery was dis-

connected. Make sure to turn off

the power before disconnecting

the 12-volt battery. Take extra

care when connecting the 12-volt

battery if the power switch mode

prior to discharge is unknown.

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. (

P.517)

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.243)

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
valves and transmitters to detect

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

the vehicle’s wheels and body.

Routine tire inflation pressure

checks

The tire pressure warning system

does not replace routine tire inflation

pressure checks. Make sure to

check tire inflation pressure as part

of your routine of daily vehicle

checks.

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

pressure warning system

The warning of the tire pressure

warning system will change in

accordance with driving conditions.

For this reason, the system may

give a warning even if the tire pres-

sure does not reach a low enough

level, or if the pressure is higher

than the pressure that was adjusted

to when the system was initialized.

When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. Have tire pressure

Replacing tires and wheels

If the ID code of the tire pressure

warning valve and transmitter is not

registered, the tire pressure warning

system will not work properly. After

driving for about 20 minutes, the tire

pressure warning light blinks for 1

minute and stays on to indicate a

system malfunction.

The tire pressure warning
system must be initialized
in the following circum-
stances:

When rotating front and rear
tires which have different tire
inflation pressures.

When changing the tire size.

When the tire inflation pres-
sure is changed such as
when changing traveling
speed or load weight.

When changing between two
registered wheel sets.

When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.

How to initialize the tire
pressure warning system

1

Park the vehicle in a safe
place and turn the power
switch off.

NOTICE

Repairing or replacing tires,

wheels, tire pressure warn-

ing valves, transmitters and

tire valve caps

When removing or fitting the

wheels, tires or the tire pressure

warning valves and transmit-

ters, contact your Toyota dealer

as the tire pressure warning

valves and transmitters may be

damaged if not handled cor-

rectly.

Make sure to install the tire

valve caps. If the tire valve caps

are not installed, water could

enter the tire pressure warning

valves and the tire pressure

warning valves could be bound.

When replacing tire valve caps,

do not use tire valve caps other

than those specified. The cap

may become stuck.

To avoid damage to the tire

pressure warning valves and

transmitters

When a tire is repaired with liquid

sealants, the tire pressure warn-

Tire inflation pressure check

interval

You should check tire inflation pres-

sure every two weeks, or at least

once a month. Do not forget to

check the spare.

Effects of incorrect tire inflation

pressure

Driving with incorrect tire inflation

pressure may result in the following:

Reduced fuel economy

Reduced driving comfort and poor

handling

Reduced tire life due to wear

Reduced safety

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

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. (

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

re

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
