how they were used previously.

NOTICE

■

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 cushion-

ing ability of the tires. In addition, driving

on rough roads may cause damage to

the tires themselves, as well as the vehi-

cle’s wheels and body.

405

6-3. Do-it-yourself maintenance

Ma
inte
na

e and care

To equalize tire wear and help extend tire
life, Lexus recommends that tire rotation is
carried out approximately every 10000
km (6000 miles) for 2WD models or
5000 km (3000 miles) for AWD models.
Do not fail to initialize the tire pressure
warning system after tire rotation.

A run-flat tire has a

mark on the side wall.



For XXX/XXRXX size tires

When run-flat tires are installed, the
vehicle can be driven for a maximum of
80 km (50 miles) at a speed below 80
km/h (50 mph) after any tire goes flat.
(However, the vehicle speed may not
increase to near 80 km/h [50 mph]
depending on weather or driving con-
ditions.)

Make sure to replace the flat tire before the
vehicle has been driven for near 80 km
(50 miles). Also, do not use a repaired tire.



For XXX/XXRFXX size tires

When run-flat tires are installed, the
vehicle can be driven for a maximum of
160 km (100 miles) at a speed below
80 km/h (50 mph) after any tire goes
flat. (However, the vehicle speed may
not increase to near 80 km/h [50
mph] depending on weather or driving
conditions.)

Make sure to replace the flat tire before the
vehicle has been driven for near 160 km
(100 miles). Also, do not use a repaired
tire.

■

Run-flat tires

●

The run-flat tires are for only this vehicle.

Do not use the tires on other vehicles.

●

Do not mix run-flat tires and normal tires.

●

If non-genuine Lexus wheels are used, it

may be impossible to sufficiently demon-

strate the performance of run-flat tires.

Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.



The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (

6-3. Do-it-yourself maintenance

■

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.

■

Tire inflation pressure

●

It may take a few minutes to display the

tire inflation pressure after the engine

switch is turned to IGNITION ON mode.

It may also take a few minutes to display

the tire inflation pressure after inflation

pressure has been adjusted.

●

Tire inflation pressure changes with tem-

perature. The displayed values may also

be different from the values measured

using a tire pressure gauge.

■

Situations in which the tire pressure

warning system may not operate prop-

erly

●

In the following cases, the tire pressure

warning system may not operate prop-

erly.

• If non-genuine Lexus wheels are used.

• If a tire has been replaced with a tire that

is not an OE (Original Equipment) tire.

• If a tire has been replaced with a tire that

is not of the specified size.

• If tire chains, etc. are installed.

• 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 vehi-

cle, particularly around the wheels or

wheel housings.

• If the tire inflation pressure is much higher

than the specified level.

• If wheels not equipped with tire pressure

warning valves and transmitter are used.

• If the ID code on the tire pressure warn-

ing valves and transmitters is not regis-

tered in the tire pressure warning

computer.

●

Performance may be affected in the fol-

lowing situations.

• When driving near a TV tower, electric

power plant, gas station, radio station,

large display, airport or other facility that

generates strong radio waves or electri-

cal noise

• When carrying a portable radio, cellular

phone, cordless phone or other wireless

communication device

If tire position information is not correctly

displayed due to the radio wave conditions,

the display may be corrected by changing

the location of the vehicle as the radio wave

conditions may change.

●

When the vehicle is stopped, the time

taken for the warning to start or turn off

may be longer.

●

When the inflation pressure of a tire

drops rapidly, for example when a tire has

burst, the warning may not operate.

■

Warning performance of the tire pres-

sure warning system

The warning of the tire pressure warning

system will change in accordance with driv-

ing conditions. For this reason, the system

may give a warning even if the tire pressure

does not reach a low enough level, or if the

pressure is higher than the pressure that

was adjusted to when the system was initial-

ized.

When replacing the tires or wheels, the
tire pressure warning valve and trans-
mitters must be installed to the wheels
which will be installed to the vehicle.

Replacing tires and wheels

If the ID codes of the tire pressure warning

valve and transmitters are not registered,

the tire pressure warning system will not

work properly. In this case, after driving for

about 10 minutes, the tire pressure warning

light will blink for approximately 1 minute

and then illuminate to indicate a system

malfunction.

■

The tire pressure warning system
must be initialized in the following
circumstances:



When the tire inflation pressure is

changed such as when changing
traveling speed or load weight.



When the tire inflation pressure is
changed such as when the tire size
is changed.



When rotating the tires.



After performing the transmitter ID
code registration procedure.

Initialization procedure

●

Make sure to perform the initialization

procedure after adjusting the tire inflation

pressure.

Also, make sure the tires are cold before

performing the initialization procedure or

adjusting the tire inflation pressure.

●

If the engine switch is turned off during

initialization, it is not necessary to restart

the initialization procedure from the

beginning as it will begin automatically

when the engine switch is turned back to

IGNITION ON mode.

●

If initialization has accidentally been

started when it is not necessary, adjust

the tire inflation pressure to the specified

level when the tires are cold and then

perform the initialization procedure

again.

●

While the position of each tire is being

determined and the inflation pressures

are not being displayed on the

multi-information display, if the inflation

pressure of a tire drops, the tire pressure

warning light will come on.

■

If the tire pressure warning system is not

initialized properly

●

In the following situations, initialization

may take longer than usual to be com-

pleted or may not be possible. (Usually,

the vehicle will need to be driven for

approximately 10 to 30 minutes to com-

plete initialization.) If initialization is not

complete after driving approximately 30

minutes, continue driving for a while.

• If the vehicle is driven on an unpaved

road, it may take longer to complete ini-

tialization.

• If the vehicle is backed up while perform-

ing initialization, data collected during ini-

tialization will be cleared and it will take

longer than normal to complete.

• If the vehicle is driven in heavy traffic or

another situation where other vehicles

are driven close by, it may take time for

the system to recognize the tire pressure

warning valve and transmitters of your

vehicle over those of other vehicles.

If initialization is not complete after driving

for approximately 1 hour, park the vehicle in

a safe place for approximately 20 minutes

and then drive the vehicle again.

After registering the ID codes, make sure

to initialize the tire pressure warning sys-

■

When registering ID codes

●

Before performing ID code registration,

make sure that no wheels with tire pres-

sure warning valve and transmitters

installed are near the vehicle.

●

Make sure to initialize the tire pressure

warning system after registering the ID

codes. If the system is initialized before

registering the ID codes, the initialized

values will be invalid.

●

As the tires will be warm when registra-

tion is completed, make sure to allow the

tires to cool before performing initializa-

tion.

■

Canceling ID code registration

●

To cancel ID code registration after it has

been started, turn the engine switch off

before driving the vehicle.

If the vehicle is driven after ID code regis-

tration is started, to cancel registration,

perform the ID code registration start

procedure again and turn the engine

switch off before driving.

●

If ID code registration has been canceled,

the tire pressure warning light will blink

for approximately 1 minute when the

engine switch is turned to IGNITION

ON mode and then illuminate. The tire

pressure warning system will be opera-

tional when the tire pressure warning

light turns off.

●

If the warning light does not turn off even

after several minutes have elapsed, ID

code registration may not have been can-

celled correctly. To cancel registration,

perform the ID code registration start

procedure again and then turn the engine

switch off before driving.

■

If ID codes are not registered properly

●

In the following situations, ID code regis-

tration may take longer than usual to be

completed or may not be possible. (Usu-

ally, the vehicle will need to be driven for

approximately 10 to 30 minutes to com-

plete ID code registration.)

If ID code registration is not complete

after driving for approximately 30 min-

utes, continue driving for a while.

• If the vehicle is driven on an unpaved

road, it may take longer than normal to

complete registration.

• If the vehicle is backed up while perform-

ing registration, data collected during

registration will be cleared, and it will take

longer than normal to complete.

• If the vehicle is driven in heavy traffic or

another situation where other vehicles

are driven close by, it may take time for

the system to recognize the tire pressure

warning valve and transmitters of your

vehicle over those of other vehicles.

• If a wheel with a tire pressure warning

valve and transmitter installed is inside or

near the vehicle, registration of the ID

codes for the installed wheels may not be

possible.

If ID registration is not complete after driv-

ing for approximately 1 hour, park the vehi-

cle in a safe place for approximately 20

minutes and then perform the ID code reg-

istration procedure again.

●

In the following situations, ID code regis-

tration will not be started or was not com-

pleted properly and the system will not

operate properly. Perform the ID code

registration procedure again.

• If, when attempting to start ID code regis-

tration, the tire pressure warning light

does not blink slowly 3 times.

• If, when the vehicle has been driven for

about 10 minutes after performing ID

code registration, the tire pressure warn-

ing light blinks for approximately 1 minute

and then illuminates.

●

If ID code registration cannot be com-

pleted after performing the above proce-

dure, contact any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer.
