● Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift position to P.
● Stop the hybrid system.
● Turn on the emergency flashers.
● Check the degree of the tire damage.

A  tire  should  only  be  repaired
with  the  emergency  tire  punc-
ture  repair  kit  if  the  damage  is
caused by a nail or screw pass-
ing through the tire tread.

• Do not remove the nail or

screw  from  the  tire.  Remov-
ing the object may widen the
opening  and  make  emer-
gency  repair  with  the  repair
kit impossible.

• To avoid sealant leakage, move the vehicle until the area of the

puncture, if known, is positioned at the top of the tire.

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 spike to
between 44 psi (300 kPa,
3.0 kgf/cm

or bar) and

58 psi (400 kPa, 4.0 kgf/cm

or  bar),  then  gradually
decrease.
The  air  pressure  gauge  will
display  the  actual  tire  infla-
tion  pressure  about  1  to  5
minutes  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  specified
tire  inflation  pressure  is
reached.

• The tire can be inflated for about 5 to 20 minutes (depending on

the outside temperature). If the tire inflation pressure is still lower
than the specified point after inflation for 25 minutes, the tire is
too damaged to be repaired. Turn the compressor switch off and
contact your Toyota dealer.

• If the tire inflation pressure exceeds the specified air pressure, let

out some air to adjust the tire inflation pressure. (

Emergency tire puncture repair kit

●

The emergency tire puncture 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 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 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 may 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 accident 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.

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 connected 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 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 bursting 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 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.
