(If equipped)
Indicates that the tire
position information
cannot be recognized
Drive for a short while
and check if the display
updates.
If the radio wave
conditions improve,
the display may
return to normal. If
the tire pressure is
still not displayed
after driving for sev-
eral minutes, stop the
vehicle in a safe
place, turn the engine
switch off then on
again, and start driv-
ing.
If the tire pressure is
still not displayed
even after repeating
this several times,
have the vehicle
inspected by any
authorized Lexus
dealer or repairer, or
another duly quali-
fied and equipped
professional.

The compact spare tire
The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily, and only in an emergency.
Make sure to check the tire inflation pressure of the compact spare tire.
(P. 850)
When using the compact spare tire
As the compact 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 system. Also, if you replace the compact spare
tire after the tire pressure warning light comes on, the light remains on.
When the compact spare tire is equipped
The vehicle becomes lower when driving with the compact spare tire com-
pared to when driving 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 and compact spare tire only)
Install the compact spare tire on one of the front wheels of the vehicle. Per-
form the following 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.

CAUTION
Speed limit when using the compact spare tire
Do not drive at speeds in excess of 80 km/h (50 mph) when a compact
spare tire is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failure to
observe this precaution may lead to an accident causing death or serious
injury.
After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in
their storage location to reduce the possibility of personal injury during a
collision or sudden braking.
NOTICE
Driving with tire chains and the compact spare tire
Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving per-
formance.
When replacing the tires
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 qualified and equipped professional as the tire pressure warn-
ing valve and transmitter may be damaged if not handled correctly.

When trouble arises
GS350/250_EE (OM30C36E)Connect the hose to the valve.
Screw the end of the hose clock-
wise as far as possible.
Check the specified tire infla-
tion pressure.
Tire inflation pressure is specified
on the label as shown. (P. 850)
Start the engine. (P. 207)
To inject the sealant and
inflate the tire, turn the com-
pressor switch on.
Use the kit with the top facing
upward.

GS350/250_EE (OM30C36E)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/cm
2 or bar, 58 psi),
then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
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 recom-
mended tire inflation pres-
sure is reached.
• If the needle of the air pres-
sure gauge reaches the red
zone (450 kPa [4.5 kgf/cm
2
or bar, 65 psi] or more), there
may be a malfunction in the
tire or in the kit itself. Stop
operation immediately.
• If the tire inflation pressure is
still lower than the recom-
mended level after inflation
for 10 minutes with the
switch on, the tire is too dam-
aged 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 pres-
sure.
(P. 813)
Disconnect the hose from the valve on the tire and then pull out
the power plug from the power outlet socket.
To spread the liquid sealant evenly within the tire, immediately
drive for about 5 km (3 miles).
After driving for about 5 km
(3 miles), stop your vehicle in
a safe place on a hard, flat sur-
face and reconnect the com-
pressor.12

8107-2. Steps to take in an emergency
GS350/250_EE (OM30C36E)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 cannot be repaired.
Contact any authorized
Lexus dealer or repairer, or
another duly qualified and
equipped professional.
If the tire inflation pressure
is between 130 kPa (1.3 kgf/
cm
2 or bar, 19 psi) and a
point below the recom-
mended level: The tire can
be repaired. Proceed to step
.
If the tire inflation pressure
is at the recommended
level: Proceed to step .
Turn the compressor switch on to inflate the tire until the recom-
mended tire inflation pressure is reached. Drive for about 5 km (3
miles) and then perform step .

In the following cases, the tire cannot be repaired with the emergency tire
puncture repair kit. Contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
When the tire is damaged due to driving without sufficient air pressure
When the tire lost air pressure due to a crack or damage in the tire sidewall
When the tire is visibly separated from the wheel
When the cut or damage to the tread is 4 mm (0.16 in.) long or more
When the wheel is damaged
When two or more tires have been punctured
When there is more than one hole or cut in the damaged tire
Emergency tire puncture repair kit
The sealant has a limited lifespan. The expiry date is marked on the bottle.
The sealant should be replaced before the expiry date. Contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional 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 in the bottle and other
parts of the kit have been used and need to be purchased, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
The sealant can be used when the outside temperature is from -30 C (-22
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 indicate a malfunction.

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. 850)
If the air pressure is lower than the recommended level, turn the compres-
sor switch on again and repeat the inflation procedure until the recom-
mended pressure is reached. 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.
CAUTION
Precautions for use of the sealant
Ingesting the sealant is hazardous to your health. If you ingest sealant,
consume as much water as possible, then immediately consult a doctor.
If sealant gets in eyes or adheres to skin, immediately wash it off with
water. If discomfort persists, consult a doctor.
