■SRS warning light
This warning light system monitors the airbag sensor assembly, front impact sensors, side
impact sensors (front door), side impact sensors (front), side impact sensors (rear),
driver’s seat position sensor, driver’s seat belt buckle switch, front passenger occupant
classification system, “AIR BAG ON” indicat or light, “AIR BAG OFF” indicator light,
front passenger’s seat belt buckle switch, seat belt pretensioner assemblies, airbags,
interconnecting wiring and power sources. (→ P. 4 3 )
■Front passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on the front passenger seat, the front passenger detection sensor
may cause the warning light to flash and the warning buzzer to sound even if a passenger
is not sitting in the seat.
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon as
possible.
■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
Check the tire inflation pressure and adjust to the appropriate level. Initializing the tire
pressure warning system will not turn off the tire pressure warning light.
■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
The compact spare tire is not equipped with a tire pressure warning valve and transmit-
ter. 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. 4 1 8
■If the tire pressure warning light freque ntly 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 your Lexus dealer.

■If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact your Lexus dealer. The vehi-
cle will become extremely unstable during br aking, 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 Lexus dealer.
●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.

■Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label (tire and load information label). (If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire
inflation pressure label [tire and load in formation label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure moni-
toring system (TPMS-tire pressure warning system) that illuminates a low tire pressure
telltale (tire pressure warning light) when on e or more of your tires is significantly
under-inflated. Accordingly, when the low ti re pressure telltale (tire pressure warning
light) illuminates, you should stop and check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale (tire pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning system) mal-
function indicator to indicate when the system is not operating properly. The TPMS
(tire pressure warning system) malfunction indicator is combined with the low tire pres-
sure telltale (tire pressure warning light). When the system detects a malfunction, the
telltale will flash for approximately one minu te and then remain continuously illumi-
nated. This sequence will continue upon su bsequent 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.
TPMS (tire pressure warning system) malfunctions may occur for a variety of reasons,
including the installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS (tire pressure warning system) from functioning properly. Always
check the TPMS (tire pressure warning syst em) malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that the replacement or alternate
tires and wheels allow the TPMS (tire pressure warning system) to continue to function
properly.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or markers, as the tire pressure warning
system may not operate properly.

Firmly tighten each wheel nut two or
three times in the order shown in the
illustration.
Tightening torque:
76 ft•lbf (103 N•m, 10.5 kgf•m)
Stow the flat tire, tire jack and all tools.
■The spare tire
●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. 5 5 0 )
■When using the spare tire
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.
■When the spare tire is equipped
The vehicle may become lower when driving with the spare tire compared to when driv-
ing with standard tires.
■If you have a flat rear tire on a road covered with snow or ice (vehicles with front and
rear tires of the same size)
Install the compact spare tire on one of the front wheels of the vehicle. Perform the fol-
lowing steps and fit tire chains to the rear tires:
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of the vehicle.
Fit tire chains to the rear tires.

■When using the spare tire
●Remember that the spare tire provided is specifically designed for use with your vehi-
cle. Do not use your spare tire on another vehicle.
●Do not use more than one spare tire simultaneously.
●Replace the spare tire with a standard tire as soon as possible.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations
that cause sudden engine braking.

When trouble arises
Check the specified tire inflation
pressure.
Tire inflation pressure is specified on the
label as shown. ( →P. 5 5 0 )
Start the engine. ( →P. 1 9 7 )
To inject the sealant and inflate the
tire, turn the compressor switch on.
Inflate the tire until the recom-
mended pressure is reached. The sealant will be injected and
the pressure will spike to 44 psi
(300 kPa, 3.0 kgf/cm
2 or bar) or
58 psi (400 kPa, 4.0 kgf/cm2 or
bar), 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.

5107-2. Steps to take in an emergency
GS350_200t_GS F_OM_OM30E86U_(U)• 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 your
Lexus dealer.
• If the tire inflation pressure exceeds the recommended level, let out some air to adjust the tire inflation pressure. ( →P. 5 1 2 , 5 5 0 )
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.
Install the valve cap onto the valve of the emergency repaired tire.
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.
Temporarily store the bottle in the trunk while it is connected to the compres-
sor.
To spread the liquid sealant evenly within the tire, immediately drive safely for
about 3 miles (5 km) below 50 mph (80 km/h).
After driving for about 3 miles
(5 km), 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.
