CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in handlingthe ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or other
body parts while changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.Oil and grease may cause the wheel nuts to be excessively tightened, leading
to bolt or disc wheel damage. In a ddition, the oil or grease can cause the
wheel nuts to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• Do not attach a heavily damaged wheel ornament, as it may fly off the wheel while the vehicle is moving.
• When installing a tire, only use wheel nuts that have been specifically designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wheel, have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.

If you have a flat tire (vehicles without a spare tire)
●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. 5 3 4 )
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 em ergency 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.
Driving with a flat tire may cause a circumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.

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.
