Canceling ID code registration

To cancel ID code registration after

it has been started, select “Register

Valve / ID” again on the multi-infor-

mation display.
If ID code registration has been can-

celed, the tire pressure warning light

will turn off.
If the warning light does not turn off,

ID code registration may not have

been cancelled correctly. To cancel

registration, select “Register Valve /

ID” on the multi-information display.

Your vehicle is equipped with a
tire pressure warning system
with a function to register two
sets of ID codes. This allows for
registration of a second wheel
set, for example a winter set.
The wheel set can be changed
only if a second wheel set has
been registered to the system. If
a second wheel set has not
been registered, it will not be
possible to change to the
selected wheel set.
ID codes can be registered by
yourself.



Only a change between both

registered wheel set is possi-
ble, mixing between these
wheel sets is not supported.



While registering ID codes, it
may not be possible to
change between wheel sets
normally. Cancel registration
before changing between
wheel sets.

Install the desired wheel set.

dealer.

Before jacking up the
vehicle

WARNING

■

Using the tire jack

Observe the following precau-

tions. Improper use of the tire jack

may cause the vehicle to sud-

denly fall off the jack, leading to

death or serious injury.

●

Do not use the tire jack for any

purpose other than replacing

tires or installing and removing

tire chains.

●

Only use the tire jack that

comes with this vehicle for

replacing a flat tire. Do not use it

on other vehicles, and do not

use other tire jacks for replacing

tires on this vehicle.

●

Put the jack properly in its jack

point.

●

Do not put any part of your body

under the vehicle while it is sup-

ported by the jack.

●

Do not start the engine or drive

the vehicle while the vehicle is

supported by the jack.

●

Do not raise the vehicle while

someone is inside.

●

When raising the vehicle, do not

put an object on or under the

jack.

●

Do not raise the vehicle to a

height greater than that required

to replace the tire.

●

Use a jack stand if it is neces-

sary to get under the vehicle.

Raise the vehicle until the tire
is slightly raised off the
ground.

Remove all the wheel nuts
and the tire.

When resting the tire on the

ground, place the tire so that the

wheel design faces up to avoid

scratching the wheel surface.

Remove any dirt or foreign
matter from the wheel con-
tact surface.

If foreign matter is on the wheel

contact surface, the wheel nuts

may loosen while the vehicle is in

motion, causing the tire to come off.

WARNING

■

Replacing a tire

Do not touch the disc wheels or

the area around the brakes imme-

diately after the vehicle has been

driven.

After the vehicle has been driven

the disc wheels and the area

around the brakes will be

extremely hot. Touching these

areas with hands, feet or other

body parts while changing a tire,

etc. may result in burns.

WARNING

■

When installing the tire

Failure to follow these precau-

tions could cause the wheel nuts

to loosen and the tire to fall off,

resulting in death or serious injury.

●

Never use oil or grease on the

wheel bolts or wheel nuts.

Oil and grease may cause the

wheel nuts to be excessively

tightened, 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 a

serious accident. Remove any

oil or grease from the wheel

bolts or wheel nuts.

●

Have the wheel nuts tightened

with a torque wrench to 76 ft•lbf

(103 N•m, 10.5 kgf•m) as soon

as possible after changing

wheels.

●

Do not attach a heavily dam-

aged wheel ornament, as it may

fly off the wheel while the vehi-

cle is moving.

●

When installing a tire, only use

wheel nuts that have been spe-

cifically designed for that wheel.

level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.

After completing the tire infla-

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.

6-4. Do-it-yourself maintenance

When replacing wheels, care
should be taken to ensure that

: 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

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.281)

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

●

Greater possibility of tire dam-

age while driving (due to road

hazards, expansion joints,

sharp edges on 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

●

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.
