When to register the position of
each wheel

It is necessary to register the position
of each wheel after performing a tire
rotation.
Wheel position registration can be
performed by oneself. Wheel position
registration is performed by driving
forward with moderate left and right
turns. However, depending on the driv-
ing conditions and driving environ-

ment, registration may take some time
to complete.

■

Registering the position of each
wheel

Park the vehicle in a safe place, turn
the engine switch off and wait 15
minutes or more.

Start the engine.

The wheel position registration procedure

cannot be performed while the vehicle is

moving.

Select

on the center display.

Select “Vehicle customize”.

Select “Tire pressure”.

Select “Tire rotation”.

Select “Continue”.

A message indicating that wheel position

registration is being performed will be dis-

played on the multi-information display.

“---” will be displayed for the tire inflation

pressure of each tire and wheel position

registration will begin.

Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.

When wheel position registration is com-

plete, a message indicating that registra-

tion has been completed and the inflation

pressure of each tire will be displayed on

the multi-information display.
Even if it is not possible to drive continu-

ously at approximately 25 mph (40 km/h)

or more, registration can be completed by

driving for a long time. However, if registra-

tion does not complete after driving for 1

hour or more, park the vehicle in a safe

place and leave it with the engine switch in

ON for approximately 15 minutes or more,

and then perform the driving procedure

again.

tire pressure warning valves, trans-

mitters and tire valve caps

●

When removing or fitting the wheels,

tires or the tire pressure warning

valves and transmitters, contact your

Lexus dealer as the tire pressure warn-

ing valves and transmitters may be

damaged if not handled correctly.

●

Make sure to install the tire valve caps.

If the tire valve caps are not installed,

water could enter the tire pressure

warning valves, corrode the valve, and

cause sticking and air leaks.

●

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 seal-

ants, the tire pressure warning valve and

every two weeks, or at least once a month.

Do not forget to check the spare.

■

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 drive train

If a tire needs frequent inflating, have it

checked by your Lexus dealer.

■

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 mile or 1.5 km, 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 gen-

erated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Never exceed the vehicle capacity

weight.

Passengers and luggage weight should

be placed so that the vehicle 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 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.

ened

■

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.441)

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.

Wheel selection

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.

wheel which is designed for a tubeless

tire.

Doing so may result in an accident,

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 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 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 prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air

during driving, possibly causing an acci-

dent.
