7-2. Steps to take in an emergency



Stop the vehicle in a safe

place on a hard, flat surface.



Set the parking brake.



Shift the shift lever to P.



Stop the hybrid system.



Turn on the emergency flash-

ers. (





For vehicles with power back

door: Turn off the power back

door system. (



P.130)



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. Removing

the object may widen the

opening and prevent emer-

gency repair with the repair

kit.

• To avoid sealant leakage,

move the vehicle until the

area of the puncture, if

known, is positioned at the

top of the tire.

If you have a flat tire

(vehicles without

spare 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 seal-

ant can be used only once

to temporarily repair one

tire without removing the

nail or screw from the tire.)

Depending on the damage

condition of the flat tire, it

may not be able to repaired

with the emergency tire

puncture repair kit.

(



P.485)

After temporarily repairing

the tire with the kit, have the

tire repaired or replaced by

your Toyota dealer.

WARNING

To inject the sealant and

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

Inflate the tire until the speci-

fied 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
be displayed the actual tire

inflation pressure about 1 to
5 minutes after the switch is
turned on.

Turn the compressor switch off and
then check the tire inflation pres-
sure. Being careful not to over
inflate, check and repeat the infla-
tion 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 compres-
sor 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. (

494

7-2. Steps to take in an emergency

WARNING

●

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.

●

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 the tire

inflation pressure is 19 psi (130

kPa, 1.3 kgf/cm

or bar) or less,

the tire may be severely dam-

aged.

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

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.

●

Place the repair kit in a storage

to prevent it from being exposed

to dirt or water.

●

Store the repair kit in the lug-

gage compartment 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

transmitters

When a tire is repaired with liquid

sealants, the tire pressure warn-

ing valve and transmitter may not

operate properly. If a liquid seal-

ant 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 repair-

ing or replacing the tire. (

WARNING

■

Replacing a flat tire

●

Do not touch the disc wheels or

the area around the brakes

immediately after the vehicle

has been driven.

After the vehicle has been

driven the disc wheels and the

area around the brakes will be

extremely hot. Touching these

areas with hands, feet or other

body parts while changing a tire,

etc. may result in burns.

• Never use oil or grease on the

wheel bolts or wheel nuts. Oil

and grease may cause the

wheel nuts to be excessively

tightened, leading to bolt or disc

wheel damage. Remove any oil

or grease that has adhered

when installing the wheel nuts.

●

Failure to follow these precau-

tions could cause the wheel

nuts to loosen and the tire to fall

off, resulting in death or serious

injury.

• After replacing a tire, check the

tightening torque as soon as

possible. Wheel nut torque: 76

ft•lbf (103 N•m, 10.5 kgf•m)

• Do not attach a heavily dam-

aged wheel ornament, as it may

fly off the wheel while the vehi-

cle is moving.

• When installing a tire, only use

wheel nuts that have been spe-

cifically designed for that wheel.

• If there are any cracks or defor-

mations in the bolt screws, nut

threads or bolt holes of the

wheel, have the vehicle

inspected by your Toyota

dealer.

• When installing the wheel nuts,

be sure to install them with the

tapered ends facing inward.

●

For vehicles with power back

door: In cases such as when

replacing tires, make sure to

turn off the power back door

system (



P.96). Failure to do

so may cause the back door to

operate unintentionally if the

power back door switch is acci-

dentally touched, resulting in

hands and fingers being caught

and injured.

removing the 12-volt battery termi-
nals, contact your Toyota dealer.

■

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 hybrid system may
be unable to start. (The 12-volt bat-
tery recharges automatically while
the hybrid system is operating.)

■

When recharging or replacing
the 12-volt battery

●

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 hybrid system may not start
on the first attempt after reinstall-
ing the 12-volt battery. In that
case, start the hybrid system in
the same manner as when the
electronic key does not operate
properly (



P.507). This is not a

malfunction, as the hybrid system
will start normally on the second
attempt.

●

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 can not be
towed without lifting both front
wheels because the front wheels
will be locked.

●

Some systems may require initial-
ization. (

P.555)

■

When replacing the 12-volt bat-
tery

●

Use a 12-volt battery that con-
forms to European regulations.

●

Use a 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 (285A) or greater.

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

tery cannot 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 12-volt battery may discharge
and hybrid system may not be
able to start.

●

Use a ventilation type calcium bat-
tery
