■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. 5 4 6 )
■When using the compact spare tire (vehicles with a tire pressure warning system)
As the compact spare tire is not equipped with a tire pressure warning valve and trans-
mitter, 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 warn-
ing 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 compared 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. 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.

●Stop the vehicle in a safe place on a hard, flat surface.
●Set the parking brake.
●Shift the shift lever to P.
●Stop the engine.
●Turn on the emergency flashers. (→P. 466)
If you have a flat tire (vehicles without a spare tire)
Your vehicle is not equipped with a spare tire, but instead is equipped with an
emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be
repaired temporarily with the emergency tire puncture repair kit.
CAUTION
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel beyond
repair, which could result in an accident.

Start the engine.
To inject the sealant and inflate the
tire, turn the compressor switch on.
Inflate the tire until the specified air
pressure is reached.
The sealant will be injected and the
pressure will surge and then gradu-
ally decrease.
The air pressure gauge will display
the actual tire inflation pressure
about 1 minute (5 minutes at low
temperature) after the switch is
turned on.
Inflate the tire until the specified air
pressure.
• Turn the compressor switch off and
then check the tire inflation pressure.
Being careful not to over inflate,
check and repeat the inflation pro-
cedure until the specified tire infla-
tion pressure is reached.
• If the tire inflation pressure is still lower than the specified point after inflation
for 35 minutes 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 specified air pressure, let out some air
to adjust the tire inflation pressure. (→P. 5 1 8 , 5 4 6 )12

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 luggage compartment while it is connected
to the compressor.
To spread the liquid sealant evenly within the tire, immediately drive safely for
about 5 km (3 miles) below 80 km/h (50 mph).
After driving for about 5 km (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 an approximately 5 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 authorized 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 specified air pressure: Proceed to .
If the tire inflation pressure is the specified air pressure (→P. 5 4 6 ) : P r o c e e d t o
.
Turn the compressor switch on to inflate the tire until the specified air pressure
is reached. Drive for about 5 km (3 miles) and then perform .
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 luggage compartment while it is connected to the com-
pressor.
Taking precautions to avoid sudden braking, sudden acceleration and sharp
turns, drive carefully at under 80 km/h (50 mph) to the nearest authorized
Lexus dealer or repairer, or another duly qualified and equipped professional

■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. 5 4 6 )
If the air pressure is lower than the recommended level, turn the compressor switch on
again and repeat the inflation procedure until the recommended 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
■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.
●Do not use the emergency tire puncture repair kit for tires that are a different size
than the specified ones or for any other purpose. Doing so may cause the tires to not
be repaired properly.
■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 discom-
fort persists, consult a doctor.

CAUTION
■When fixing the flat tire
●Stop your vehicle in a safe and flat area.
●Do not touch the wheels or the area around the brakes immediately after the vehicle
has been driven.
After the vehicle has been driven, the wheels and the area around the brakes may be
extremely hot. Touching these areas with hands, feet or other body parts may result in
burns.
●Connect the valve and hose securely with the tire installed on the vehicle.
●If the hose is not properly connected to the valve, air leakage may occur or sealant
may be sprayed out.
●If the hose comes off the valve while inflating the tire, there is a risk that the hose will
move abruptly due to air pressure.
●After inflation of the tire has completed, the sealant may splatter when the hose is dis-
connected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedure is not followed, the
sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it bursting
while the repair operation is being performed. If you notice any cracks or deforma-
tion of the tire, turn off the compressor switch and stop the repair operation immedi-
ately.
●The kit may overheat if operated for a long period of time. Do not operate the com-
pressor continuously for more than 10 minutes.
●Parts of the kit become hot during operation. Be careful handling the kit during and
after operation.
●Do not attach the vehicle speed warning sticker to an area other than the one indi-
cated. If the sticker is attached to an area where an SRS airbag is located, such as the
pad of the steering wheel, it may prevent the SRS air bag from operating properly.
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop
the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 130 kPa (1.3 kgf/cm
2 or bar, 19 psi)
or below, this may indicate severe tire damage.
