roads, the use of snow tires is recom-
mended. When installing snow tires, be
sure to replace all four tires.

●

All season tires

All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions as well
as for use year-round. All season tires,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in acceleration and handling per-
formance compared with summer tires in
highway driving.

●

Snow tires

For driving on snow-covered roads or icy
roads, we recommend using snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also have
radial construction. Do not install studded
tires without first checking local regula-
tions for possible restrictions. Snow tires
should be installed on all wheels.

WARNING

■

When inspecting or replacing tires

Observe the following precautions to

prevent accidents.

Failure to do so may cause damage to

parts of the drive train as well as danger-

ous handling characteristics, which may

lead to an accident resulting in death or

serious injury.

●

Do not mix tires of different makes,

models or tread patterns.

Also, do not mix tires of remarkably

different treadwear.

●

Do not use tire sizes other than those

recommended by Lexus.

●

Do not mix differently constructed

tires (radial, bias-belted or bias-ply

tires).

●

Do not mix summer, all season and

snow tires.

●

Do not use tires that have been used

on another vehicle.

Do not use tires if you do not know

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.

are

Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.



Vehicles with front and rear tires of
differing sizes

Tires cannot be rotated.

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
50 miles (80 km) at a speed below 50
mph (80 km/h) after any tire goes flat.
(However, the vehicle speed may not
increase to near 50 mph [80 km/h]
depending on weather or driving con-
ditions.)

Make sure to replace the flat tire before the
vehicle has been driven for near 50 miles
(80 km). 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
100 miles (160 km) at a speed below
50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may
not increase to near 50 mph [80
km/h] depending on weather or driv-
ing conditions.)

Make sure to replace the flat tire before the
vehicle has been driven for near 100 miles
(160 km). 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. (

P.77)



If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a

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.
When new tire pressure warning
valves and transmitters are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. (

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.

●

In the following situations, initialization

will not be started or was not completed

properly and the system will not operate

properly. Perform the initialization proce-

dure again.

• If, when attempting to start initialization,

the tire pressure warning light does not

blink 3 times.

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
