If the change wheel set mode is canceled,

the ID codes that have already been reg-

istered are communicated. When com-

munication is finished, the tire pressure

warning light will turn off.

When ID code registration may not

operate properly

Do not move the vehicle backward

during registration. Registration is started

again from the beginning and it may take

longer than usual.

When another vehicle is running the side

of the vehicle such as in heavy traffic, it

may take longer to detect the vehicle’s

tire pressure warning valves and trans-

mitters.

If tire pressure warning valves and trans-

mitters are in the vehicle, the ID codes

may not be registered.

If registration takes long time, perform the
procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable
repairer.

Effects of incorrect tire inflation pres-

sure

Driving with incorrect tire inflation pressure

may result in the following:

Reduced fuel economy

Reduced driving comfort and poor han-

dling

Reduced tire life due to wear

Reduced safety

Damage to the drivetrain

If a tire needs frequent inflating, have it

checked by any authorized Lexus retailer

or Lexus authorized repairer, or any reli-

able repairer.

Instructions for checking tire inflation

pressure

When checking tire inflation pressure,

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 1.5 km or 1 mile, you will get an

accurate cold tire inflation pressure read-

ing.

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 gener-

ated in the tire. Do not reduce tire infla-

tion pressure after driving.

Passengers and luggage weight should

be placed so that the vehicle is balanced.

WARNING

When installing the tire

Failure to follow these precautions 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, lead-

ing 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 140 N•m (14.3

kgf•m, 103.3 ft•lbf) as soon as possible

after changing wheels.

Do not attach a heavily damaged

wheel ornament, as it may fly off the

wheel while the vehicle is moving.

When installing a tire, only use wheel

nuts that have been specifically

designed for that wheel.

If there are any cracks or deformations

in the bolt screws, nut threads or bolt

holes of the wheel, have the vehicle

inspected by any authorized Lexus

retailer or Lexus authorized repairer,

or any reliable repairer.

After using the tools

Before driving, make sure all the tools

are stored securely in place. Failure to do

so may cause injury in case of a collision

or sudden braking.

Tire inflation pressure

Make sure to maintain proper tire
inflation pressure. Tire inflation
pressure should be checked at
least once per month. However,
Lexus recommends that tire infla-
tion pressure be checked once
every two weeks.

6-3. Do-it-yourself maintenance

When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset

Replacement wheels are available at
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer.

: Conventionally referred to as offset.

Lexus 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 trans-

mitters that allow the tire pressure warning

system to provide advance warning in the

event of a loss in tire inflation pressure.

Whenever wheels are replaced, tire pres-

sure warning valves and transmitters must

be installed. (



P.337)

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 serious 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 dam-

age

Greater possibility of tire damage

while driving (due to road hazards,

expansion joints, sharp edges in the

road, etc.)

NOTICE

When inspecting and adjusting tire

inflation pressure

Be sure to put the tire valve caps back

on.

If a valve cap is not installed, dirt or mois-

ture may get into the valve and cause an

air leak, resulting in decreased tire infla-

tion pressure.

Wheels

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



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



When rotating, repairing or chang-

ing your tires, check that the wheel
nuts are still tight after driving 1600
km (1000 miles).



Be careful not to damage the alumi-
num wheels when using tire chains.



Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
your wheels.

WARNING

When replacing wheels

Do not use wheels that are a different

size from those recommended 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.

Use of defective wheels prohibited

Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air

during driving, possibly causing an acci-

dent.

NOTICE

Replacing tire pressure warning

valves and transmitters

Because tire repair or replacement

may affect the tire pressure warning

valves and transmitters, make sure to

have tires serviced by any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer or

other qualified service shop. In addi-

tion, make sure to purchase your tire

pressure warning valves and transmit-

ters at any authorized Lexus retailer or

Lexus authorized repairer, or any reli-

able repairer.

Ensure that only genuine Lexus wheels

are used on your vehicle.

Tire pressure warning valves and

transmitters may not work properly

with non-genuine wheels.
