The 12-volt battery is located on the 
right-hand side of the trunk.

Q

Before recharging

When recharging, the 12-volt battery pro-

duces hydrogen gas which is flammable 

and explosive. Therefore, observe the fol-

lowing precautions before recharging:

O

If recharging with the 12-volt battery 

installed on the vehicle, be sure to dis-

connect the ground cable.

O

Make sure the power switch on the char-

ger is off when connecting and discon-

necting the charger cables to the 12-volt 

battery.

Q

After recharging/reconnecting the 12-

volt battery

O

The hybrid system may not start. Follow 

the procedure below to initialize the sys-

tem.

1

Shift the shift lever to P.

2

Open and close any of the doors.

3

Restart the hybrid system.

O

Unlocking the doors using the smart 

entry & start system may not be possible 

immediately after reconnecting the 12-

volt battery. If this happens, use the wire-

less remote control or the mechanical 

key to lock/unlock the doors.

O

switch in ACCESSORY mode. The 

hybrid system may not start with the 

power switch turned off. However, the 

hybrid system will operate normally from 

the second attempt.

O

The power switch mode is recorded by 

the vehicle. If the 12-volt battery is recon-

nected, the vehicle will return the power 

switch mode to the status it was in before 

the 12-volt battery was disconnected. 

Make sure to turn off the power switch 

before disconnect the 12-volt battery. 

Take extra care when connecting the 12-

volt battery if the power switch mode 

prior to discharge is unknown.

Q

When to replace your vehicle’s tires

O

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 any authorized 
Lexus retailer or Lexus authorized repairer, 
or any reliable repairer.

O

Vehicles with 17-inch tires:

The wheel angle differs from vehicles 

equipped with 18-inch/19-inch tires. 

Therefore, 18-inch/19-inch tires cannot 

be installed, as sufficient gaps with sur-

rounding parts cannot be ensured.

Q

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.

Q

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.

Q

If the tread on snow tires wears down 

below 4 mm (0.16 in.)

The effectiveness of the tires as snow tires is 

lost.

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.

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

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:

re

Rotate the tires in the order shown.

To equalize tire wear and help extend tire 
life, Lexus recommends that tire rotation is 
carried out approximately every 10000 
km (6000 miles).
Do not fail to initialize the tire pressure 
warning system after tire rotation.

Q

When rotating the tires

Make sure that the power switch is off. If the 

tires are rotated while the power switch is in 

ON mode, the tire position information will 

not be updated.

If this accidentally occurs, either turn the 

power switch to off and then to ON mode, 

or initialize the tire pressure warning system 

after checking that the tire pressure is prop-

erly 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.410)

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

P.107)

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 mode. It may also 

take a few minutes to display the tire infla-

tion pressure after inflation pressure has 

NOTICE

O

Be sure to use proper tire inflation 

pressure. If tires are under-inflated, 

they may be damaged more severely.

O

Avoid potholes, uneven pavement, 

curbs and other road hazards. Failure 

to do so may lead to severe tire and 

wheel damage.

Q

If tire inflation pressure of each tire 

becomes low while driving

Do not continue driving, or your tires 

and/or wheels may be ruined.

O

Tire inflation pressure changes with tem-

perature. The displayed values may also 

be different from the values measured 

using a tire pressure gauge.

Q

Situations in which the tire pressure 

warning system may not operate prop-

erly

O

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.

• 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.

O

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 pressure warning computer and 
the tire pressure warning system must 
be initialized. (

P.379)

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.

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 mode.

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

Q

Effects of incorrect tire inflation pres-

sure

Driving with incorrect tire inflation pressure 

may result in the following:

O

Reduced fuel economy

O

Reduced driving comfort and poor han-

dling

O

Reduced tire life due to wear

O

Reduced safety

O

Damage to the drivetrain

If a tire needs frequent inflating, have it 

checked by any authorized Lexus retailer 

or Lexus authorized repairer, or any reli-

able repairer.

Q

Instructions for checking tire inflation 

pressure

When checking tire inflation pressure, 

observe the following:

O

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 1.5 km or 1 mile, you will get an 

accurate cold tire inflation pressure read-

ing.

O

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly 

inflated based only on its appearance.

O

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.

O

Passengers and luggage weight should 

be placed so that the vehicle is balanced.

Tire inflation pressure

Make sure to maintain proper tire 
inflation pressure. Tire inflation 
pressure should be checked at 
least once per month. However, 
Lexus recommends that tire infla-
tion pressure be checked once 
every two weeks.

WARNING

Q

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:

O

Excessive wear

O

Uneven wear

O

Poor handling

O

Possibility of blowouts resulting from 

overheated tires

O

Air leaking from between tire and 

wheel

O

Wheel deformation and/or tire dam-

age

O

Greater possibility of tire damage 

while driving (due to road hazards, 

expansion joints, sharp edges in the 

road, etc.)

NOTICE

Q

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 

air leak, resulting in decreased tire infla-

tion pressure.

Q

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 and transmitters must 

be installed. (

P.376)

Use only Lexus wheel nuts and 
wrenches designed for use with 
your aluminum wheels.

When rotating, repairing or chang-

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.

WARNING

Q

When replacing wheels

O

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.

O

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.

Q

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.

NOTICE

Q

Replacing tire pressure warning 

valves and transmitters

may affect the tire pressure warning 

valves and transmitters, make sure to 

have tires serviced by any authorized 

Lexus retailer or Lexus authorized 

repairer, or any reliable repairer or 

other qualified service shop. In addi-

tion, make sure to purchase your tire 

pressure warning valves and transmit-

ters at any authorized Lexus retailer or 

Lexus authorized repairer, or any reli-

able repairer.

O

Ensure that only genuine Lexus wheels 

are used on your vehicle.

Tire pressure warning valves and 

transmitters may not work properly 

with non-genuine wheels.
