Scion Q EV. Service Manual - part 23

Check the specified tire inflation
pressure.

Tire inflation pressure is specified
on the label on the driver’s side
pillar as shown. (

Inflate the tire until the specified

air pressure is reached.

The sealant will be injected
and the pressure will spike to
44 psi (300 kPa, 3.1 kgf/cm

or bar) or 58 psi (400 kPa,
4.1 kgf/cm

or bar), and then

gradually decrease.

The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
(15 minutes at low tempera-
ture) after the switch is
turned on.

Inject to specified air pres-
sure.

• Turn the compressor switch

off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the infla-
tion procedure until the
specified tire inflation pres-
sure is reached.

• If the tire inflation pressure

is still lower than the speci-
fied point after inflation for
10 minutes (40 minutes at
low temperature) with the
switch on, the tire is too
damaged to be repaired.
Turn the compressor switch
off and contact your Scion
dealer.

• If the tire inflation pressure

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

P. 371, 400 )

With the compressor switch off, disconnect the hose from the valve
on the tire and then pull out the power plug from the power outlet
socket.

Some sealant may leak when the hose is removed.

Install the valve cap onto the valve of the emergency repaired tire.

Attach the air release cap to the
end of the hose.

If the air release cap is not
attached, the sealant may leak
and the vehicle may get dirty.

Temporarily store the bottle in the luggage room while it is con-
nected to the compressor.

To spread the liquid sealant evenly within the tire, immediately drive
safely for about 3 miles (5 km) below 50 mph (80 km/h).

After driving for about 3 miles (5
km), stop your vehicle in a safe
place on a hard, flat surface
and remove the air release cap
from the hose before recon-
necting the repair kit.

Turn the compressor switch on
and wait for several seconds,
and then turn it off. Check the
tire inflation pressure.

If the tire inflation pressure is
under 19 psi (130 kPa, 1.3
kgf/cm

or bar): The puncture

cannot be repaired. Contact
your Scion dealer.

If the tire inflation pressure is
19 psi (130 kPa, 1.3 kgf/cm

or bar) or higher, but less
than the specified air pres-
sure: Proceed to step

If the tire inflation pressure is
the specified air pressure:
Proceed to step

Turn the compressor switch on to inflate the tire until the specified
air pressure is reached. Drive for about 3 miles (5 km) and then
perform step

Attach the air release cap to the
end of the hose.

If the air release cap is not
attached, the sealant may leak
and the vehicle may get dirty.

Store the bottle in the luggage room while it is connected to the
compressor.

Taking precautions to avoid sudden braking, sudden acceleration
and sharp turns, drive carefully at under 50 mph (80 km/h) to the
nearest Scion dealer tire repair or replacement.

■

Emergency tire puncture repair kit

●

The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant has been used
and needs to be replaced, purchase a new bottle at any authorized
Scion dealer. The compressor is reusable.

●

The sealant can be used when the outside temperature is from -40

F

(-40

C) to 140 F (60 C).

●

The repair 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.

●

The sealant has a limited lifespan. The expiry date is shown on the bot-
tle. The sealant should be replaced before the expiry date. Purchase a
new bottle at your Scion dealer for replacement.

●

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.

If the tire is inflated to more than the specified air pressure

Disconnect 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, then turn
it off. Check that the air pressure indicator shows the specified air pres-
sure. (

P. 400)

If the air pressure is under the designated pressure, turn the compres-
sor switch on again and repeat the inflation procedure until the speci-
fied air pressure is reached.

■

The valve of a tire that has been repaired

After a tire is repaired with the emergency tire puncture repair kit, the tire
pressure warning valve and transmitter should be replaced.

■

Note for checking the emergency tire puncture repair kit

Check the sealant expiration 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.

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

■

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 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 or sealant may be sprayed out.

●

Follow the operation procedure to repair the tire. If the procedures are
not followed, the sealant may spray 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.

●

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 60 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.

CAUTION

■

Driving to spread the liquid sealant evenly

Observe the following precautions to reduce the risk of accidents.
Failure 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 following:

• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 19 psi (130 kPa,

1.3 kgf/cm

or bar) or less, this may indicate severe tire damage.

■

Caution while driving

●

Store the repair kit in the luggage room.
Otherwise, the repair kit may fly out and break in events such as sud-
den braking, and may cause an accident.

●

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.

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. 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 organic substances such as benzene or gasoline splatters on the
repair kit, the repair kit may deteriorate. Take care not to allow organic
substances 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 assigned place 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 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 Scion dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. (
