■

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 tire 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,

and then turn it off. Check that

the air pressure indicator shows

the specified air pressure.

(



P.358)

If the air pressure is under the des-

ignated 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 emer-

gency tire puncture repair kit, the

valve should be replaced.

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.

■

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.

●

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 as 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 dis-

connected or some air is let out

of the tire.

●

Follow the operation procedure

to repair the tire. If the proce-

dures not followed, the sealant

may spray out.

338

7-2. Steps to take in an emergency

WARNING

●

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 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.

■

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 tire

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

or bar) or

below, this may indicate severe

tire damage.

NOTICE

■

When performing an emer-

gency repair

●

A tire should only be repaired

with the emergency tire punc-

ture 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.

●

Make sure to stand the kit with

the bottle vertical. The kit can-

not work properly if it is laid on

its side.

■

Precautions for the emer-

gency 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 repair kit may deteriorate.

Take care not to allow fuel to

contact it.

removed, the information stored in

the ECU is cleared. Before remov-

ing the battery terminals, contact

your Toyota dealer.

■

Charging the battery

The electricity stored in the battery

will discharge gradually even when

the vehicle is not in use, due to nat-

ural discharge and the draining

effects of certain electrical appli-

ances. If the vehicle is left for a long

time, the battery may discharge,

and the engine may be unable to

start. (The battery recharges auto-

matically during driving.)

■

When recharging or replacing

rized by the vehicle. When the

battery is reconnected, the system

will return to the mode it was in

before the battery was dis-

charged. Before disconnecting the

battery, turn the engine switch off.

If you are unsure what mode the

engine switch was in before the

battery discharged, be especially

careful when reconnecting the

battery.

■

When replacing the battery

●

Use a battery that conforms to

European regulations.

●

Type A: Use a battery that the

case size is same as the previous

one (LN2), 20 hour rate capacity

(20HR) is equivalent (60Ah) or

greater, and performance rating

(CCA) is equivalent (345A) or

greater.

●

Type B: Use a battery that the

case size is same as the previous

one (LN3), 20 hour rate capacity

346

7-2. Steps to take in an emergency

(20HR) is equivalent (70Ah) or

greater, and performance rating

(CCA) is equivalent (600A) or

greater.

• If the sizes differ, the battery can-

not be properly secured.

• If the 20 hour rate capacity is low,

even if the time period where the

vehicle is not used is a short time,

the battery may discharge and the

engine may not be able to start.

●

After replacing, firmly attach the

following items to the exhaust hole

of the battery.

• Use the exhaust hose that was

attached to the battery before

replacing and confirm that it is

firmly connected to the hole sec-

tion of the vehicle.

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 battery.
