Check if the treadwear indicators are
showing on the tires. Also check the
tires for uneven wear, such as exces-
sive wear on one side of the tread.
Check the spare tire condition and
pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is
shown by a “TWI” or “
” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indica-
tors are showing on a tire.
■
When to replace your vehicle’s tires
●
Tires should be replaced if:
• The treadwear indicators are showing on
a tire.
• You have tire damage such as cuts, splits,
cracks deep enough to expose the fabric,
and bulges indicating internal damage
• A tire goes flat repeatedly or cannot be
properly repaired due to the size or loca-
tion of a cut or other damage
If you are not sure, consult your Lexus
dealer.
●
Vehicles with 17-inch tires:
The wheel angle differs from vehicles
equipped with 18-inch/19-inch tires. There-
fore, 18-inch/19-inch tires cannot be
installed, as sufficient gaps with surrounding
parts cannot be ensured.
■
Tire life
Any tire over 6 years old must be checked
by a qualified technician even if it has sel-
dom or never been used or damage is not
obvious.
■
Low profile tires (18-inch/19-inch tires)
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use
snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for
road and weather conditions.
■
Maximum load of tire
Check that the maximum load of the
replacement tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR) of
either the front axle or the rear axle, which-
ever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the
load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the
tire. (

Tire types
●
Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway driv-
ing under dry conditions. Since summer
tires do not have the same traction per-
formance as snow tires, summer tires are
inadequate for driving on snow-covered
or icy roads. For driving on snow-cov-
ered roads or icy roads, the use of snow
tires is recommended. 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 ade-
quate for driving in most winter condi-
tions as well as for use year-round. All
season tires, however, do not have ade-
quate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance com-
pared 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
regulations for possible restrictions.
Snow tires should be installed on all
wheels. (
■
If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
WARNING
■
When inspecting or replacing tires
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drivetrain 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 tow if your vehicle has a com-
pact spare tire installed.
●
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.
■
Low profile tires (18-inch/19-inch
tires)
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:

Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
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.
■
When rotating the tires
Make sure that the engine switch is off. If the
tires are rotated while the engine switch is
in IGNITION ON mode, the tire position
information will not be updated.
If this accidentally occurs, either turn the
engine switch to off and then to IGNITION
ON mode, or initialize the system after
checking that the tire pressure is properly
adjusted.
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.
If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. (
The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. (
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■
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.
NOTICE
●
Be sure to use proper tire inflation
pressure. If tires are under-inflated,
they may be damaged more severely.
●
Avoid potholes, uneven pavement,
curbs and other road hazards. Failure
to do so may lead to severe tire and
wheel damage.
■
If tire inflation pressure of each tire
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.

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.
• A tire has been replaced with a tire that is
not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is
not of the specified size.
• Tire chains etc. are equipped.
• 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 extremely
higher than the specified level.
• If wheel without tire pressure warning
valves and transmitters 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.
• Near a TV tower, electric power plant,
gas station, radio station, large display,
airport or other facility that generates
strong radio waves or electrical 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 driving and
changing the radio wave conditions.
●
When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●
When tire inflation pressure declines rap-
idly for example when a tire has burst, the
warning may not function.
■
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 tires or wheels, tire
pressure warning valves and transmit-
ters must also be installed.
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. (
■
When replacing the tires and wheels
If the ID code of the tire pressure warning
valve and transmitter is not registered, the
tire pressure warning system will not work
properly. After driving for about 20 min-
utes, the tire pressure warning light blinks
for 1 minute and stays on to indicate a sys-
tem malfunction.

Drive at approximately 25 mph
(40 km/h) or more for approxi-
mately 10 to 30 minutes.
When initialization is complete, the infla-
tion pressure of each tire will be displayed
on the multi-information display.
Even if the vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more, initial-
ization can be completed by driving for a
long time. However, if initialization does
not complete after driving for 1 hour or
more, park the vehicle in a safe place for
approximately 20 minutes and then drive
the vehicle again.
■
When initializing
●
Initialization is performed while driving at
a vehicle speed of approximately 25 mph
(40 km/h) or more.
●
Make sure to carry out initialization after
adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initialization or tire inflation
pressure adjustment.
●
The tire pressure warning system can be
initialized by yourself, but depending on
the driving conditions and driving envi-
ronment, initialization may take some
time to complete.
■
The initialization operation
●
If you have accidentally turned the engine
switch off during initialization, it is not
necessary to manually restart the initial-
ization again, as initialization will restart
automatically the next time the engine
switch is turned to IGNITION ON
mode.
●
If you accidentally perform initialization
when initialization is not necessary, adjust
the tire inflation pressure to the specified
level when the tires are cold, and conduct
initialization 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 pres-
sure 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. Normally,
initialization completes within approxi-
mately 30 minutes.
• Vehicle is not driven at approximately 25
mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles and
system cannot recognize tire pressure
warning valve and transmitters of your
vehicle over those of other vehicles
If initialization does not complete after driv-
ing for 1 hour or more, park the vehicle in a
safe place for approximately 20 minutes
and then drive the vehicle again.
●
If the vehicle is reversed during initializa-
tion, the data up to that point is reset, so
perform the initialization procedure
again from the beginning.
●
In the following situations, initialization
will not be started or was not completed
properly and the system will not operate
properly. Perform the initialization pro-
cedure again.
• If, when attempting to start initialization,
the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for
about 20 minutes after performing initial-
ization, the tire pressure warning light
blinks for approximately 1 minute and
then illuminates.
If initialization cannot be completed after
performing the above procedure, contact
your Lexus dealer.

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.)
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

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. (
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 1000
miles (1600 km).
Vehicles with 17-inch tires: Be care-
ful not to damage the aluminum
wheels when using tire chains.
Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
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.

■
When replacing wheels
●
Do not use wheels that are a different
size from those recommended in the
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.
