To inject the sealant and

inflate the tire, turn the com-
pressor switch on.

Inflate the tire until the rec-

ommended 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 inflation
pressure about 1 to 5 min-
utes 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 speci-
fied 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 infla-
tion for 25 minutes, the tire is too
damaged to be repaired. Turn the
compressor switch off and con-
tact your Toyota dealer.

• If the tire inflation pressure

exceeds the specified air pres-
sure, let out some air to adjust the
tire inflation pressure. (

sor.

Taking precautions to avoid

sudden braking, sudden
acceleration and sharp turns,
drive carefully at under 50
mph (80 km/h) to the nearest
Toyota dealer that is less
than 62 miles (100 km) away
for tire repair or replacement.

For repair and replacement of a tire

or disposal of the tire puncture

repair kit, contact your Toyota

dealer.
When having the tire repaired or

replaced, make sure to tell the Toy-

ota dealer that the sealant is

injected.

■

If the tire is inflated to more

than the specified air pressure

Disconnect the hose from the

valve.

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.

Disconnect the hose from the

valve, remove the air release cap

from the hose and then recon-

nect the hose.

Turn the compressor switch on

and wait for several seconds,

then turn it off. Check that the air

pressure indicator shows the

specified air pressure is reached.

(

If the air pressure is under the

designated pressure, turn the

compressor switch on again and

repeat the inflation procedure

until the specified air pressure is

reached.

■

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.

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 immedi-

ately 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.

536

8-2. Steps to take in an emergency

WARNING

●

Connect the valve and hose

securely with the tire installed

on the vehicle.

If the hose is not properly con-
nected 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 dis-

connected or some air is let out

of the tire.

●

Follow the operation procedure

to repair the tire. If the proce-

dure 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 per-

formed. If you notice any cracks

or deformation of the tire, turn

off the compressor switch and

stop the repair operation imme-

diately.

●

The repair kit may overheat if

operated for a long period of

time. Do not operate the com-

pressor 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

air bag from operating properly.

■

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

straight or you feel a pull

through the steering wheel, stop

the vehicle and check the fol-

lowing:

• 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

or bar) or less,

the tire may be severely dam-

aged.

NOTICE

■

When performing an emer-

gency repair

●

Perform the emergency repair

without removing the nail or

screw that has punctured the

tread of the tire. If the object

that has punctured the tire is

removed, repair by the emer-

gency tire puncture repair kit

The EV system cannot be started by

push-starting.

■

To prevent 12-volt battery dis-

charge

●

Turn off the headlights, the air

conditioning system, the audio

system, etc. while the EV system

is off.

●

Turn off any unnecessary electri-

cal components when the vehicle

is running at a low speed for an

extended period, such as in heavy

traffic.

■

Charging the 12-volt battery

The electricity stored in the 12-volt

battery will discharge gradually even

when the vehicle is not in use, due

to natural discharge and the drain-

ing effects of certain electrical appli-

ances. If the vehicle is left for a long

time, the 12-volt battery may dis-

charge, and the EV system may be

unable to start. (The 12-volt battery

recharges automatically while the

EV system is operating.)

■

When the 12-volt battery is

removed or discharged

●

Information stored in the ECU is

cleared. When the 12-volt battery

is depleted, have the vehicle

inspected at your Toyota dealer.

●

In some cases, it may not be pos-

sible to unlock the doors using the

smart key system when the 12-

volt battery is discharged. Use the

wireless remote control or the

mechanical key to lock or unlock

the doors.

●

The EV system may not start on

the first attempt after the 12-volt

battery has recharged but will start

normally after the second attempt.

This is not a malfunction.

●

The power switch mode is memo-

rized by the vehicle. When the 12-

volt battery is reconnected, the

system will return to the mode it

was in before the 12-volt battery

was discharged. Before discon-

necting the 12-volt battery, turn

the power switch off.

If you are unsure what mode the

power switch was in before the

12-volt battery discharged, be

especially careful when recon-

necting the 12-volt battery.

●

If the 12-volt battery discharges, it

may not be possible to shift the

shift position to other positions. In

this case, the vehicle cannot be

towed without lifting both front

wheels because the front wheels

will be locked.

●

The power back door (if equipped)

544

P.181)

■

When replacing the 12-volt bat-

tery

●

Use a 12-volt battery that con-

forms to European regulations.

●

Use a 12-volt battery that the case

size is same as the previous one

(LN1), 20 hour rate capacity

(20HR) is equivalent (45Ah) or

greater, and performance rating

(CCA) is equivalent (286A) or

greater.

• If the sizes differ, the 12-volt bat-

tery cannot be properly secured.

• If an improper 12-volt battery is

used, battery performance may

decrease and the EV system may

not be able to restart.

• If the 20 hour rate capacity is low,

even if the time period where the

vehicle is not used is a short time,

the 12-volt battery may discharge

and EV system may not be able to

start.

For details, consult your Toyota

dealer.

WARNING

■

When removing the 12-volt

battery terminals

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

■

Avoiding 12-volt battery fires

or explosions

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the 12-volt battery:

●

Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.

●

Do not allow the other end of

the jumper cable connected to

the “+” terminal to come into

contact with any other parts or

metal surfaces in the area, such

as brackets or unpainted metal.

●

Do not allow the + and - clamps

of the jumper cables to come

into contact with each other.

●

Do not smoke, use matches,

cigarette lighters or allow open

flame near the 12-volt battery.

■

12-volt battery precautions

The 12-volt battery contains poi-

sonous and corrosive acidic elec-

trolyte, while related parts contain

lead and lead compounds.

battery, always wear safety

glasses and take care not to

allow any battery fluids (acid) to

come into contact with skin,

clothing or the vehicle body.

●

Do not lean over the 12-volt bat-

tery.

●

In the event that battery fluid

(acid) comes into contact with

the skin or eyes, immediately

wash the affected area with

water and seek medical atten-

tion.
