When trouble arises
WARNING
●If the tire pressure warning light comes
on even after tire inflation pressure
adjustment, 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
Lexus dealer.
●Avoid abrupt maneuvering and brak-
ing. If the vehicle tires deteriorate, you
could lose control of the steering
wheel or the brakes.
Vehicles with an emergency tire punc-
ture repair kit
●Stop your vehicle in a safe place as
soon as possible. Adjust the tire infla-
tion pressure immediately.
●If the tire pressure warning light comes
on even after tire inflation pressure
adjustment, it is probable that you have
a flat tire. Check the tires. If a tire is flat,
repair the flat tire by using emergency
tire puncture repair kit.
●Avoid abrupt maneuvering and brak-
ing. 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.
■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], you should determine
the proper tire infl ation pressure for
those tires.)
As an added safety fe ature, 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 ti re 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 maintena nce, 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.

■Emergency tire puncture repair kit
●The sealant has a lim ited lifespan. The
expiry date is marked on the bottle. The
sealant should be re placed before the
expiry date. Contact your Lexus dealer
for replacement.
●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
purchased, contact your Lexus dealer.
The compressor is reusable.
●The sealant can be used when the outside
temperature is from -40°F (-40°C) to
140°F (60°C).
●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 opera-
tion 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.
■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 con-
ducted using the emergency tire puncture
repair kit may not be performed properly.

■Caution while driving
Observe the following precautions.
Failure to do so may cause an accident.
●The emergency tire puncture repair kit
is made exclusively for your vehicle.
Do not use it on other vehicles.
