When trouble arises
8-2. Steps to take in an emergency
If you have a flat 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 using the emergency tire
puncture repair kit. (The kit contains a bottle of sealant. The
sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.) After temporar-
ily repairing the tire with the kit, have the tire repaired or
replaced by your Toyota dealer.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short dist ance with a flat tire can damage the tire and the
wheel beyond repair, which could result in an accident.

When trouble arises
■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.
■After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
●Even if the tire inflation pressure is at the recommended 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 conducted using the emer-
gency tire puncture repair kit may not be performed properly.
■Emergency tire puncture repair kit
●The emergency tire punctu re repair kit is for filling the car tire with air.
●The sealant has a limited life span. The expiry date is marked on the
bottle. The sealant should be replaced before the expiry date. Contact
your Toyota dealer for replacement.
●The sealant stored in the emergency ti re 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 replaced, con-
tact your Toyota dealer.
●The compressor can be used repeatedly.
●The sealant can be used when the outside temperature is from -40°F
(-40°C) to 140°F (60°C).
●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 repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
●Do not use to check or to adjust the tire pressure.

WARNING
■Do not drive the vehicle with 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.
Driving with a flat tire may cause a circumferential groove on the side
wall. In such a case, the tire ma y explode when using a repair kit.
■Caution while driving
●Store the repair kit in the luggage compartment.
Injuries may result in the event of an accident or sudden braking.
●The repair kit is exclusively only for your vehicle.
Do not use repair kit on other vehicles, which could lead to an accident
causing death or serious injury.
●Do not use repair kit for tires that are different size than the original
ones, or for any other purpose. If the tires have not been completely
repaired, it could lead to an accide nt causing death or serious injury.
■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 discomfort persists, consult a doctor.

When trouble arises
WARNING
■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 vehi-
cle. If the hose is not properly co nnected to the valve, air leakage may
occur as 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 abru ptly due to air pressure.
●After inflation of the tire has comp leted, 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 bursting while the repair op eration is being performed. If you
notice any cracks or deformation of the tire, turn off the compressor
switch and stop the repair operation immediately.
●The repair kit may overheat if operated for a long period of time. Do not
operate the repair kit continuously for more than 40 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 airbag from operating properly.

WARNING
■Driving to spread the liquid sealant evenly
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death
or serious injury.
●Drive the vehicle carefully at a low speed. Be especially careful when
turning and cornering.
●If the vehicle does not drive strai ght 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 the tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm
2 or bar) or less, the tire may be severely dam-
aged.
NOTICE
■When performing an emergency repair
●A tire should only be repaired with the emergency tire puncture repair
kit if the damage is caused by a sharp object such as nail or screw
passing through the tire tread.
Do not remove the sharp object from the tire. Removing the object may
widen the opening and disenable emergency repair with the repair kit.
●The repair kit is not waterproof. Ma ke 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.
■Precautions for 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 fuel splatters on the repair kit, the repa ir kit may deteriorate. Take
care not to allow fuel to contact it.
●Place the repair kit in a storage to prevent it from being exposed to dirt
or water.
●Store the repair kit in the luggage compartment out of reach of chil-
dren.
●Do not disassemble or modify the repair kit. Do not subject parts such
as the air pressure indicator to im pacts. This may cause a malfunction.

When trouble arises
NOTICE
■To avoid damage to the tire pressure warning valves and transmit-
ters
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 your Toyota dealer or other qualified service shop as soon
as possible. After use of liquid sealant, make sure to replace the tire
pressure warning valve and transmitter when repairing or replacing the
tire. ( →P. 595)
