Maintenance and care
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. ( P.249)
■If the tread on snow tires wears down
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
■Replacing tires (vehicles with run-flat
tires)
Your vehicle may not be equipped with the
following tools and jack for replacing a tire.
In this case, when replacing tires with tires
that are not run-flat tires, purchase tools
and jack. Tools and jack can be purchased
at your Lexus dealer.
●Wheel nut wrench
●Jack
●Jack handle
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 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.
●Vehicles with compact spare tire: Do
not tow if your vehicle has a compact
spare tire installed.
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.
■If tire inflation pressure of each tire
becomes low while driving (vehicles
without run-flat tires)
Do not continue driving, or your tires
and/or wheels may be ruined.

3306-3. Do-it-yourself maintenance
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 engi ne switch is OFF. If
the tires are rotated while the engine switch
is in ON, the tire position information will
not be updated.
If this accidentally oc curs, either turn the
engine switch to OFF and then to ON, or
initialize the tire pr essure warning system
after checking that the tire pressure is prop-
erly adjusted.
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.)
A run-flat tire has a mark on
the sidewall.
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 ti re 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. ( P.359, 367)
 The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P.79)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.

Maintenance and care
■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 ON. 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.
• 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 wheels 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 stat ion, large display,
airport or other faci lity 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 pr essure 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 the
conditions under which it was initialized. 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 initialized.

3326-3. Do-it-yourself maintenance
■Certification for tire pressure warning system
For vehicles sold in the U.S.A. , Hawaii, Guam and Puerto Rico
For vehicles sold in Canada
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 pres-
sure warning computer and the tire pres-
sure warning system must be initialized.

Maintenance and care
■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.
■The tire pressure warning system
must be initialized in the following
circumstances:
 When rotating the tires.
 When the tire inflation pressure is
changed such as when changing tire
size. (When there are multiple spec-
ified pressures)
 After registering the ID codes.
( P.335)
When the tire pressure warning system
is initialized, the current tire inflation
pressure is set as the benchmark pres-
sure.
■How to initialize the tire pressure
warning system
1
Park the vehicle in a safe place and
stop the engine for 20 minutes or
more.
Initialization cannot be performed while
the vehicle is moving.
2Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level.
Make sure to adjust the tire pressure to the
specified cold tire inflation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.

■Repairing or replacing tires, wheels,
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 and the tire pressure
warning valves could be bound.
●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
transmitter may not operate properly. If a
liquid sealant is used , contact your Lexus
dealer or other qualified service shop as
soon as possible. After use of liquid seal-
ant, make sure to re place the tire pres-
sure warning valve and transmitter when
repairing or replacing the tire.

sure of each tire on the multi-information
display.
6Drive at 25 mph (40 km/h) or
more for approximately 10 to 30
minutes.
Registration is complete when the tire
pressure warning light turns off and the
inflation pressure of each tire is displayed
on the multi-information display.
Even if the vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more, regis-
tration can be completed by driving for a
long time. However, if registration does not
complete after driving for 1 hour or more,
perform the procedure again from the
beginning.
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation
pressure to the specified level. Other-
wise, the tire pressure warning light may
not come on even if the tire inflation pres-
sure is low, or it may come on when the
tire inflation pressure is actually normal.

system. ( P.333)
■When registering ID codes
●ID code registration is performed while
driving at a vehicle speed of approxi-
mately 25 mph (40 km/h) or more.
●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.
●ID codes can be registered by yourself,
but depending on the driving conditions
and driving environment, registration
may take some time to complete.
■Canceling ID code registration
●To cancel ID code registration after it has
been started, turn th e 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 ON and then
illuminate. The tire pressure warning sys-
tem will be operational 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-
celed correctly. To cancel registration,
perform the ID code registration start
procedure again and th en 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. Nor-
mally, registration completes within
approximately 30 minutes. • Vehicle is not parked for approximately
20 minutes or more before driving
• 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 valves and transmitters of your
vehicle over those of other vehicles
• Wheel with tire pr essure warning valve
and transmitter installe d is inside or near
the vehicle
If registration does not complete after driv-
ing for 1 hour or more, perform the ID code
registration proced ure again from the
beginning.
●If the vehicle is reve rsed during registra-
tion, the data up to that point is reset, so
perform the registration procedure again
from the beginning.
●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. Pe rform 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 20 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 your Lexus dealer.
