■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. 6 4 5 )
■When using the compact spare tire (vehicles with the tire pressure warning sys-
tem)
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 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
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 stor-
age 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 perfor-
mance.
■When replacing the tires (vehicles with the tire pressure warning system)
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 quali-
fied and equipped professional as the tire pressure warning valve and transmitter
may be damaged if not handled correctly.

■If the tire is inflated to more than the recommended levelDisconnect 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, and then turn it off.
Check that the air pressure indicator shows the recommended level. ( →P. 6 4 5 )
If the air pressure is lower than the recommended level, turn the compressor
switch on again and repeat the inflation procedure until the recommended pres-
sure is reached.
■The valve of a tire that has been repaired
●After a tire is repaired with the emergency tire puncture repair kit, the valve should
be replaced.
●Vehicles with the tire pressure warning system: After a tire is repaired with the
emergency tire puncture repair kit, even if the tire inflation pressure is at the recom-
mended level, the tire pressure warning light may come on/flash.
■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. Install the air release cap to the end of the
hose and push the protrusion on the air
release cap into the tire 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.

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, and then immediately consult a doctor.
●If sealant gets in eyes or adheres to skin, immediately wash it off with water. If dis-
comfort persists, consult a doctor.
■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 seal-
ant 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
disconnected or some air is let out of the tire.
●Follow the operation procedure to repair the tire. If the procedures not followed,
the sealant may spray out.
●Keep back from the tire while it is being repaired, as there is a chance of it burst-
ing while the repair operation is being performed. If you notice any cracks or
deformation of the tire, turn off the compressor switch and stop the repair opera-
tion immediately.
●The repair kit may overheat if operated for a long period of time. Do not operate
the repair kit continuously for more than 35 minutes.
●Parts of the repair kit become hot during operation. Be careful handling the
repair kit during and after operation. Do not touch the metal part connecting the
bottle and the compressor. It will be extremely hot.
●Do not attach the vehicle speed warning sticker to an area other than the one
indicated. 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 operat-
ing properly.

NOTICE
■When performing an emergency repair
●Perform the emergency repair without removing the nail or screw that has punc-
tured the tread of the tire. If the object that has punctured the tire is removed,
repair by the emergency tire puncture repair kit may not be possible.
●The repair kit is not waterproof. Make sure that the repair kit is not exposed to
water, such as when it is being used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the side of the
road. If the repair kit vacuums up dust etc., a malfunction may occur.
■Handling the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not
connect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate. Take care not
to allow gasoline to contact it.
●Store the emergency tire puncture repair kit in the trunk.
The kit may be thrown around during sudden braking and so forth, damaging the
kit.
●Store the repair kit in the trunk out of reach of children.
●Do not disassemble or modify the repair kit. Do not subject parts such as the air
pressure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressure warning valves and transmitters (vehicles
with the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (→P. 4 6 8 )
