■When a tire is replaced with a spare tire (vehicles with a spare tire)
The spare tire is also equipped with a tire pressure warning valve and transmitter. The
tire pressure warning light will turn on if the tire inflation pressure of the spare tire is
low. If a tire goes flat, the tire pressure warning light will not turn off even though the
flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
P. 511
■If the tire pressure warning light frequently comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the power switch is turned to ON mode, have it checked by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
■Warning buzzer
In some cases, the buzzer may not be heard due to ambient noise or sounds from the
audio system.

CAUTION
■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional. The vehicle
will become extremely unstable during braking, 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
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate 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
vehicle control and result in death or serious injury.
●As the tire inflation pressure may be low when this warning light is illuminated,
stop your vehicle in a safe place as soon as possible and adjust the tire inflation
pressure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
●Avoid abrupt maneuvering and braking. If the 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.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pressure warn-
ing system may not operate properly.

CAUTION
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their stor-
age location to reduce the possibility of personal injury during a collision or sudden
braking.
NOTICE
■When replacing the tires (vehicles with the tire pressure warning system)
When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. ( P. 508)

it is impossible to attach the label,
make sure to tell any authorized Lexus
dealer or repairer, or another duly
qualified and equipped professional
when you have them repair and
replace the tire that sealant is injected.
Check the specified tire inflation
pressure.
Tire inflation pressure is specified on
the label as shown. ( P. 630)

LS600h/LS600hL_EE(OM50G20E)
Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected and
the pressure will spike to 300
kPa (3.0 kgf/cm2 or bar, 44
psi) or 400 kPa (4.0 kgf/cm2
or bar, 58 psi), then gradually
decrease.
The air pressure gauge will dis-
play the actual tire inflation
pressure about 1 minute (15
minutes at low temperature)
after the switch is turned on.
• Turn the compressor switch off
and then check the tire inflation
pressure. Being careful not to
over inflate, check and repeat
the inflation procedure until the
recommended tire inflation
pressure is reached.
• If the tire inflation pressure is still
lower than the recommended
level after inflation for 10 min-
utes (35 minutes at low tem-
perature) with the switch on, the
tire is too damaged to be
repaired. Turn the compressor
switch off and contact any
authorized Lexus dealer or
repairer, or anot her duly quali-
fied and equipped professional.
• If the tire inflation pressure
exceeds the recommended
level, let out some air to adjust
the tire inflation pressure.

Turn the compressor switch on
and wait for several seconds, then
turn it off. Check the tire inflation
pressure.
If the tire inflation pressure is
below 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi): The puncture can-
not be repaired. Contact any
authorized Lexus dealer or
repairer, or another duly quali-
fied and equipped profes-
sional.
If the tire inflation pressure is
between 130 kPa (1.3 kgf/cm
2
or bar, 19 psi) and a point
below the recommended level:
The tire can be repaired. Pro-
ceed to step .
If the tire inflation pressure is at
the recommended level: Pro-
ceed to step .
Turn the compressor switch on to inflate the tire until the recommended
tire inflation pressure is reached. Drive for about 5 km (3 miles) and
then perform step .
Attach the air release cap to the
end of the hose.
If the air release cap is not attached,
the sealant may leak and the vehicle
may get dirty.

Store the bottle in the trunk while it is connected to the compressor.
Taking precautions to avoid sudden braking, sudden acceleration and
sharp turns, drive carefully at under 80 km/h (50 mph) to any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped
professional that is less than 100 km (62 miles) away for tire repair or
replacement.
■Emergency tire puncture repair kit
●The sealant has a limited lifespan. The expiry date is marked on the bottle. The seal-
ant should be replaced before the expiry date. Contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional for replace-
ment.
●The sealant stored in the emergency tire puncture repair kit can be used only once
to temporarily repair a single tire. If the sealant has been used and needs to be pur-
chased, contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional. The compressor is reusable.
●The sealant can be used when the outside temperature is from -40 C (-40F) to
60 C (140F).
●The kit is exclusively designed for size and type of tires originally installed on your
vehicle. Do not use it for tires that a different size than the original ones, or for any
other purposes.
●If the sealant gets on your clothes, it may stain.
●If the sealant adheres to a wheel or the surface of the vehicle body, the stain may
not be removable if it is not cleaned at once. Immediately wipe away the sealant
with a wet cloth.
●During operation of the kit, a loud operation noise is produced. This does not indi-
cate a malfunction.
●Do not use the emergency tire puncture repair kit to check or to adjust the tire
pressure.

■If the tire is inflated to more than the recommended level
Disconnect the hose from the valve.
Disconnect the hose from the valve, remove the air release cap from the hose and
then reconnect the hose.
Turn the compressor switch on and wait for several seconds, then turn it off. Check
that the air pressure indicator shows the recommended level. ( P. 630)
If the air pressure is lower than the recommended level, turn the compressor
switch on again and repeat the inflation procedure until the recommended pres-
sure is reached.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended level, the tire pressure
warning light may come on/flash.
■Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry date has
already passed. Otherwise, repairs conducted using the emergency tire puncture
repair kit may not be performed properly.
Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the valve to let some air
out.
