6-3. Do-it-yourself maintenance

If the tire inflation pressure settings for the

installed tires change, initialization opera-

tions are required, but if the tire inflation

pressure settings are the same, initializa-

tion is not required.

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

Changing a second wheel set is complete

when the tire pressure warning light turns

off and the inflation pressure of each tire is

displayed on the multi-information display.

The recommended cold tire inflation
pressure and tire size are displayed on
the tire and loading information label.

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pressure
gauge onto the tire valve.

Read the pressure using the gauge
gradations.

If the tire inflation pressure is not at
the recommended level, adjust the
pressure.
If you add too much air, press the
center of the valve to deflate.

After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.

Put the tire valve cap back on.

■

Tire inflation pressure check interval

You should check tire inflation pressure

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 refilling, 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 gener-

ated 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.)

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
your Lexus dealer.

: 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.469)

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.

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.

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



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

●

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 your Lexus

dealer or other qualified service shop.

In addition, make sure to purchase

your tire pressure warning valves and

transmitters at your Lexus dealer.

●

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.

Inspect the tires to check if a tire is punc-

tured.
If a tire is punctured:



P.511

If none of the tires are punctured:
Turn the engine switch to OFF then turn it

to ON. Check if the tire pressure warning

light comes on or blinks.



If the tire pressure warning light blinks for

approximately 1 minute then stays on

There may be a malfunction in the tire pres-
sure warning system. Have the vehicle
inspected by your Lexus dealer immedi-
ately.



If the tire pressure warning light comes

After the temperature of the tires has

lowered sufficiently, check the inflation

pressure of each tire and adjust them to

the specified level.

If the warning light does not turn off

even after several minutes have

elapsed, check that the inflation pres-

sure of each tire is at the specified level

and perform initialization. (

The tire pressure warning light may come

on due to natural causes such as natural air

leaks and tire inflation pressure changes

caused by temperature. In this case, adjust-

warning light (after a few minutes).

■

When a tire is replaced with a spare tire

The spare tire is also equipped with the tire

pressure warning valve and transmitter. The

If a tire goes flat, even though the flat tire is

replaced with the spare tire, the tire pres-

sure warning light does not turn off.

Replace the spare tire with the repaired tire

and adjust the proper tire inflation pressure.

The tire pressure warning light will turn off

after a few minutes.

WARNING

■

When the electric power steering

system warning light comes on

When the light comes on yellow, the

assist to the power steering is restricted.

When the light comes on red, the assist

to the power steering is lost and handling

operations of the steering wheel become

extremely heavy.

When steering wheel operations are

heavier than usual, grip the steering

wheel firmly and operate it using more

force than usual.

■

If the tire pressure warning light

comes on

Be sure to observe the following precau-

tions. Failure to do so could cause a loss

of vehicle control and result in death or

serious injury.

●

Stop your vehicle in a safe place as

soon as possible. Adjust the tire infla-

tion pressure immediately.

●

If the tire pressure warning light comes

on even after tire inflation pressure

adjustment, it is probable that you have

a flat tire. Check the tires. If a tire is flat,

change it with the spare tire and have

the flat tire repaired by the nearest

Lexus dealer.

●

Avoid abrupt maneuvering and brak-

ing. If the vehicle tires deteriorate, you

could lose control of the steering

wheel or the brakes.

■

If a blowout or sudden air leakage

should occur

The tire pressure warning system may

not activate immediately.

■

Maintenance of the tires

Each tire, including the spare (if pro-

vided), should be checked monthly when

cold and inflated to the inflation pressure

recommended by the vehicle manufac-

turer on the vehicle placard or tire infla-

tion pressure label (tire and load

information label). (If your vehicle has

tires of a different size than the size indi-

cated on the vehicle placard or tire infla-

tion pressure label [tire and load

information label], you should determine

the proper tire inflation pressure for

those tires.)

As an added safety feature, your vehicle

has been equipped with a tire pressure

monitoring system (TPMS-tire pressure

warning system) that illuminates a low

tire pressure telltale (tire pressure warn-

ing light) when one or more of your tires

is significantly under-inflated. Accord-

ingly, when the low tire pressure telltale

(tire pressure warning light) illuminates,

you should stop and check your tires as

soon as possible, and inflate them to the

proper pressure. Driving on a signifi-

cantly under-inflated tire causes the tire

to overheat and can lead to tire failure.

Under-inflation also reduces fuel effi-

ciency and tire tread life, and may affect

the vehicle’s handling and stopping abil-

ity.

Please note that the TPMS (tire pressure

warning system) is not a substitute for

proper tire maintenance, and it is the

driver’s responsibility to maintain correct

tire pressure, even if under-inflation has

not reached the level to trigger illumina-

tion of the TPMS low tire pressure telltale

(tire pressure warning light).
