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. ( P.289)
 The tire pressure detected by the 
tire pressure warning system can be 
displayed on the multi-information 
display. ( P.69)
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.
■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 tires not equipped with 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 af fected in the fol-
lowing situations.
• Near a TV tower, electric power plant,  gas station, radio stat ion, large display, 
airport or other fac ility 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.
Tire pressure warning system 

2626-3. Do-it-yourself maintenance
■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 
traveling speed.
 When changing the tire size.
When the tire pressure warning system 
is initialized, the cu rrent 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 
turn the engine switch off.
Initialization cannot  be performed while 
the vehicle is moving.
2 Adjust the tire inflation pressure to 
the specified cold tire inflation pres-
sure level.
Make sure to adjust th e tire pressure to the 
specified cold tire infl ation pressure level. 
The tire pressure warning system will oper-
ate based on this pressure level.
3 Turn the engine switch to IGNI-
TION ON mode.
4 Press and hold the tire pressure 
warning reset switch until the tire  pressure warning light blinks slowly 
3 times.
5 Wait for a few minutes with the 
engine switch in IGNITION ON 
mode and then turn the engine 
switch off.
■Initialization procedure
●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.
●If you have accidentally turned the engine 
switch off during initialization, it is not 
necessary to press the reset switch again 
as initialization will restart automatically 
when the engine switch has been turned 
to IGNITION ON mode for the next 
time.
●If you accidentally press the reset switch 
when initialization is  not necessary, adjust 
the tire inflation pressure to the specified 
level when the tires are cold, and conduct 
initialization again.
■When initialization of the tire pressure 
warning system has failed
Initialization ca n be completed in a few min-
utes. However, in the  following cases, the 
settings have not been recorded and the 
system will not operate  properly. If repeated 
attempts to record tire inflation pressure 
settings are unsuccessf ul, have the vehicle 
inspected by your Lexus dealer.
●When operating the tire pressure warn-
ing reset switch, the tire pressure warning 
light does not blink 3 times.

Maintenance and care
●After carrying out the initialization proce-
dure, the tire pressure warning light 
blinks for 1 minute then stays on after 
driving for 20 minutes.
The tire pressure warning valve and 
transmitter is equipped with a unique 
ID code. When replacing a tire pres-
sure warning valve and transmitter, it is 
necessary to register the ID code. 
Have the ID code registered by your 
Lexus dealer.The recommended cold tire inflation 
pressure and tire size are displayed on 
the tire and loading information label.

WARNING
■When initializing the tire pressure 
warning system
Do not operate the ti re pressure warning 
reset switch without first adjusting the tire 
inflation pressure to the specified level. 
Otherwise, the tire pressure warning 
light may not come on even if the tire 
inflation pressure is low, or it may come 
on when the tire inflation pressure is 
actually normal.

Maintenance and care
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 straight-
ened
■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 an d transmitters must 
be installed. ( P.261)
 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).
 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.
Wheels
If a wheel is bent, cracked or heavily 
corroded, it should be replaced. 
Otherwise, the tire may separate 
from the wheel or cause a loss of 
handling control.
Wheel selection
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.
●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.
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 qua lified 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 trans-
mitters may not work properly with 
non-genuine wheels.

When trouble arises
WARNING
■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], yo u should determine 
the proper tire infl ation 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 warnin g 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).
Your vehicle has also been equipped with 
a TPMS (tire pressure warning system) 
malfunction indicator  to indicate when 
the system is not operating properly. The 
TPMS (tire pressure warning system) 
malfunction indicator is combined with 
the low tire pressure telltale (tire pres-
sure warning light) . When the system 
detects a malfunction, the telltale will 
flash for approximately one minute and 
then remain continuously illuminated. 
This sequence will continue upon subse-
quent vehicle start-ups as long as the 
malfunction exists. When the malfunction 
indicator is illuminated, the system may 
not be able to detect or signal low tire 
pressure as intended.
TPMS (tire pressure warning system) 
malfunctions may occur for a variety of 
reasons, including the installation of 
replacement or alternate tires or wheels 
on the vehicle that prevent the TPMS 
(tire pressure warning system) from func-
tioning properly. Always check the 
TPMS (tire pressure warning system) 
malfunction telltale after replacing one 
or more tires or wheels on your vehicle to 
ensure that the replacement or alternate 
tires and wheels allow the TPMS (tire 
pressure warning system) to continue to 
function properly.
NOTICE
■To ensure the tire pressure warning 
system operates properly
Do not install tires with different specifi-
cations or makers, as the tire pressure 
warning system may not operate prop-
erly. 

3027-2. Steps to take in an emergency
■When the spare tire is equipped
The vehicle becomes lower when driving 
with the spare tire compared to when driv-
ing with standard tires.
■If you have a flat rear  tire on a road cov-
ered with snow or ice (vehicles with 
front and rear tires of the same size 
except for vehicles with LDH and 
19-inch tires)
Install the spare tire on one of the front 
wheels of the vehicle. Perform the following 
steps and fit tire chains to the rear tires:
1
Replace a front tire with the spare tire.
2
Replace the flat rear tire with the tire 
removed from the front of the vehicle.
3
Fit tire chains to the rear tires.
WARNING
■When using the spare tire
●Remember that the spare tire provided 
is specifically desi gned for use with 
your vehicle. Do not use your spare 
tire on another vehicle.
●Do not use more than one spare tire 
simultaneously.
●Replace the spare tire with a standard 
tire as soon as possible.
●Avoid sudden acceleration, abrupt 
steering, sudden braking and shifting 
operations that cause sudden engine 
braking.
■When the spare tire is attached
The vehicle speed may not be correctly 
detected, and the following systems may 
not operate correctly:
• ABS & Brake assist
• VSC
• TRAC
• Dynamic radar cruise control
• PCS

■Speed limit when using the spare tire
Do not drive at speeds in excess of 50 
mph (80 km/h) when a spare tire is 
installed on the vehicle.
The spare tire is not designed for driving 
at high speeds. Failure to observe this 
precaution may lead to an accident caus-
ing death or serious injury.
■After using the tools and jack
