■Electric power steering system warning light (warning buzzer)
When the battery charge becomes insufficient or the voltage temporarily drops, the
electric power steering system warning light may come on and the warning buzzer may
sound.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes, check that the tire infla-
tion pressure is at the specifie d level and carry out initialization.
The warning light may come on again if the above operations are conducted without first
allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural air
leaks and tire inflation pressure changes caused by temperature. In this case, adjusting
the tire inflation pressure will turn off the warning light (after a few minutes).
■When a tire is replaced with a spare tire
Vehicles with a compact spare tire: The compact spare tire is not equipped with a tire
pressure warning valve and transmitter. 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.
Vehicles with full-size spare tire: The spare tire is also equipped with a tire pressure warn-
ing valve and transmitter. The tire pressure warn ing light will turn on if the tire inflation
pressure of the spare tire is low. If a tire go es 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. 4 7 0
■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
engine switch is turned to IGNITION 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 because of noisy place or an audio sound.

■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 oper-
ate 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.
●Stop your vehicle in a safe place as soon as possible. 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 specificatio ns or makers, as the tire pressure warning
system may not operate properly.

→Check the tire inflation pressure, and adjust to the
appropriate level.
(If equipped)
Indicates a malfunction in th e tire pressure warning sys-
tem
→ Stop the vehicle in a safe place and turn the engine
switch off then on again. If the tire pressure warning
indicator flashes for 1 minute then illuminates, there

Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
103 N•m (10.5 kgf•m, 76 ft•lbf)
Vehicles with a full-size spare tire:
Reinstall the wheel ornament.
Stow the flat tire, tire jack and all tools.
■The spare tire (GS350/GS200t with compact spare tire, and GS F)
●GS350/GS200t: The spare tire is identified by the label “TEMPORARY USE ONLY”
on the tire sidewall.
●Use the spare tire temporarily, and only in an emergency.
●Make sure to check the tire inflation pressure of the spare tire. (→P. 6 2 3 )
■When using the spare tire* (vehicles with the tire pressure warning system)
As the spare tire is not equipped with a tire pressure warning valve and transmitter, low
inflation pressure of the spare tire will not be indicated by the tire pressure warning sys-
tem. Also, if you replace the spare tire after the tire pressure warning light comes on, the
light remains on.

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/cm
2 or bar, 44 psi) or
400 kPa (4.0 kgf/cm2 or bar, 58
psi), and then gradually decrease.
The air pressure gauge will dis-
play the actual tire inflation pres-
sure about 1 minute (15 minutes at
low temperature) after the switch
is turned on.
Inject to recommended pressure.
• 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 spec-
ified tire inflation pressure is
reached.
• If the tire inflation pressure is still lower than the specified point after inflation for 10 minutes (35 minutes at low temperature) 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 another duly qualified and equipped
professional.
• If the tire inflation pressure exceeds the recommended level, let out some air to
adjust the tire inflation pressure. ( →P. 5 7 9 , 6 2 3 )
With the compressor switch off, disconnect the hose from the valve on the tire
and then pull out the power plug from the power outlet socket.
Some sealant may leak when the hose is removed.

(3 miles), stop your vehicle in a safe
place on a hard, flat surface and
remove the air release cap from the
hose before reconnecting the repair
kit.
Turn the compressor switch on and
wait for several seconds, and then
turn it off. Check the tire inflation
pressure.If the tire inflation pressure is
under 130 kPa (1.3 kgf/cm
2 or
bar, 19 psi): The puncture cannot
be repaired. Contact any autho-
rized Lexus dealer or repairer, or
another duly qualified and
equipped professional.
If the tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or bar, 19 psi) or higher,
but less than the recommended level: Proceed to step .
