Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pressure 
gauge onto the tire valve.
3 Read the pressure using the gauge 
gradations.
4 If the tire inflation pressure is not at 
the recommended level, adjust the 
pressure.
If you add too much air, press the 
center of the valve to deflate.
5 After completing the tire inflation 
pressure measurem ent and adjust-
ment, apply soapy water to the 
valve and check for leakage.
6 Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire  inflation pressure 
every two weeks, or at least once a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pres-
sure
Driving with incorrect ti re inflation pressure 
may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor han-
dling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drivetrain
If a tire needs frequent inflating, have it 
checked by your Lexus dealer.
■Instructions for checking tire inflation 
pressure
When checking tire inflation pressure, 
observe the following:
●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 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 ti
re inflation pressure 
to be higher after driving as heat is gen-
erated 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.)

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 wa rning 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.305)
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 
air leak, resulting in decreased tire infla-
tion pressure.
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. 

3166-3. Do-it-yourself maintenance
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).
 Use only Lexus genuine balance 
weights or equivalent and a plastic 
or rubber hammer when balancing 
your wheels. 1
Turn the engine switch 
2 Open the glove box.
3 Remove the panel.
4 Unlock the filter cover ( ), pull 
the filter cover out of the claws 
( ), and remove the filter cover.
WARNING
●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.
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 qualified service shop. 
In addition, make sure to purchase 
your tire pressure warning valves and 
transmitters at your Lexus dealer.
●Ensure that only ge nuine Lexus wheels 
are used on your vehicle.
Tire pressure warning valves and trans-
mitters may not work properly with 
non-genuine wheels.

towing service, using a wheel-lift 
type truck or flatbed truck.
Use a safety chain system for all 
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions. 
Failure to do so may result in death or 
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle 
with all four wheels raised off the ground. 
If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and 
related parts may be damaged or an 
accident may occur due to a change in 
direction of the vehicle.
LC500h: Be sure to transport the vehi-
cle with all four wheels raised off the 
ground. If the vehicle is towed with the 
tires contacting the ground, the drive-
train and related parts may be damaged, 
an accident may occur due to a change 
in direction of the vehicle or electricity 
generated by the operation of the motor 
may cause a fire to occur depending on 
the nature of the damage or malfunction.
■While towing
●When towing using cables or chains, 
avoid sudden starts, etc. which place 
excessive stress on the towing eyelets, 
cables or chains. The towing eyelets, 
cables or chains may become dam-
aged, broken debris may hit people, 
and cause serious damage.
●Do not turn the engine switch 
This may lead to an accident as the 
rear wheels will be locked by the park-
ing lock. 
Also, there is a possibility that the 
steering wheel is locked and cannot be 
operated.

■The tire pressure warning light may come on due to natural causes
The tire pressure warnin g light may come on due to natural  causes such as natural air leaks 
and tire inflation pressure chan ges caused by temperature. In this case, adjusting the tire 
inflation pressure will turn off the warning light (after a few minutes).
■Conditions that the tire pressure wa rning system may not function properly
 P.304
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning lig ht frequently comes on after blinking for 1 minute when the 
engine switch 
checked by your Lexus dealer.
■Warning buzzer
In some cases, the buzzer may not be heard du e to being in a noisy location or audio sound.
■Customization
The vehicle speed linked seat belt reminder buzzer can be disabled. 
(Customizable features:  P.391)
WARNING
■If both the ABS and the brake sy stem warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehicle 
will become extremely unstable during brakin g, and the ABS system may fail, which could 
cause an accident resulting  in death or serious injury.
■When the electric power steering  system warning light comes on
When the light comes on in yellow, the assist to the power steering is restricted. When the 
light comes on red, the assist  to the power steering is lost and handling operations of the 
steering wheel become extremely heavy. When steering wheel operations are heavier 
than usual, grip the steering  wheel firmly and operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a loss of vehi-
cle control and result in death or serious injury.
●Decelerate to the lowest appr opriate speed as soon as possible. Do not drive over 50 
mph (80 km/h).
●Check and adjust the tire in flation pressure immediately.
●If the tire pressure warning lig ht comes on even after tire inflation pressure adjustment, 
it is probable that you have  a flat tire. Have the flat tire replaced by the nearest Lexus 
dealer.
●Avoid abrupt maneuvering and braking. If th e vehicle tires deteriorate, you could lose 
control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system  may not activate immediately.
