WARNING

Q

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.

O

Do not mix tires of different makes, 

models or tread patterns. 

Also, do not mix tires of remarkably 

different treadwear.

O

Do not use tire sizes other than those 

recommended by Lexus.

O

Do not mix differently constructed 

tires (radial, bias-belted or bias-ply 

tires).

O

Do not mix summer, all season and 

snow tires.

O

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.

O

Vehicles with compact spare tire: Do 

not tow if your vehicle has a compact 

spare tire installed.

O

Vehicles with emergency tire punc-

ture repair kit: Do not tow anything if a 

tire that has been repaired using the 

emergency tire puncture repair kit is 

installed. The load on the tire may 

cause unexpected damage to the tire.

NOTICE

Q

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.

Q

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.

6-3. Do-it-yourself maintenance

the tires are rotated while the power switch 

is in ON, the tire position information will 

not be updated. 

If this accidentally occurs, either turn the 

power switch to OFF and then to ON, or 

initialize the tire pressure 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 
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.)

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 160 
km (100 miles). Also, do not use a repaired 
tire.

Q

Run-flat tires

O

The run-flat tires are for only this vehicle. 

Do not use the tires on other vehicles.

O

Do not mix run-flat tires and normal tires.

O

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.

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

P.413, 422)

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

P.108)

The illustration used is intended as an 
example, and may differ from the image 
that is actually displayed on the multi-infor-
mation display.

Q

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.

Q

Tire inflation pressure

O

It may take a few minutes to display the 

tire inflation pressure after the power 

switch is turned to ON. It may also take a 

few minutes to display the tire inflation 

pressure after inflation pressure has been 

adjusted.

O

Tire inflation pressure changes with tem-

perature.

The displayed values may also be differ-

ent from the values measured using a tire 

pressure gauge.

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.

O

When the vehicle is parked, the time 

taken for the warning to start or go off 

could be extended.

O

When tire inflation pressure declines rap-

idly for example when a tire has burst, the 

warning may not function.

Q

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.

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. 
(

P.386)

Q

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 10 minutes, 

the tire pressure warning light blinks for 1 

minute and stays on to indicate a system 

malfunction.

Q

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.386)

When the tire pressure warning sys-
tem is initialized, the current tire infla-
tion pressure is set as the benchmark 
pressure.

Q

How to initialize the tire pressure 
warning system

1

Park the vehicle in a safe place and 
stop the hybrid system for 20 min-
utes or more.

Initialization cannot be performed while 

the vehicle is moving.

2

Adjust the tire inflation pressure to 
the specified cold tire inflation 
pressure 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.

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.

O

When replacing tire valve caps, do not 

use tire valve caps other than those 

specified. The cap may become stuck.

Q

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 any autho-

rized Lexus retailer or Lexus authorized 

repairer, or any reliable repairer or other 

qualified service shop as soon as possi-

ble. After use of liquid sealant, make sure 

to replace the tire pressure warning 

valve and transmitter when repairing or 

replacing the tire.

Drive at approximately 40 km/h 
(25 mph) 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 40 km/h (25 mph) 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.

Q

When initializing

O

Initialization is performed while driving at 

a vehicle speed of approximately 40 

km/h (25 mph) or more.

O

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.

O

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.

Q

The initialization operation

O

If you have accidentally turned the power 

switch off during initialization, it is not 

necessary to manually restart the initial-

ization again, as initialization will restart 

automatically the next time the power 

switch is turned to ON.

O

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.

O

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.

Q

If the tire pressure warning system is not 

initialized properly

O

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 40 

km/h (25 mph) 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.

O

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.

O

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 the inflation pressure of each tire is still not
