Assemble the jack handle
extension.

Raise the vehicle until the tire
is slightly raised off the
ground.

Remove all the wheel nuts
and the tire.

When resting the tire on the

ground, place the tire so that the

wheel design faces up to avoid

scratching the wheel surface.

Remove any dirt or foreign
matter from the wheel con-
tact surface.

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 vehi-

cle 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.

●

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.

• Have the wheel nuts tightened

with a torque wrench to 76 ft•lbf

(103 N•m, 10.5 kgf•m) as soon

as possible after changing

wheels.

• 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.

■

Starting the hybrid system

when the 12-volt battery is dis-

charged

The hybrid system cannot be started

by push-starting.

412

7-2. Steps to take in an emergency

■

To prevent 12-volt battery dis-

charge

●

Turn off the headlights and the

audio system while the hybrid sys-

tem 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.

■

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.

●

Some systems may require initial-

ization. (



P.452)

■

When removing the 12-volt bat-

tery terminals

When the 12-volt battery terminals

are removed, the information stored

in the ECU is cleared. Before

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 (vehicles

with a smart key system)

●

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 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.

■

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 (295A) 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 the hybrid 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.

WARNING

■

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.

Observe the following precautions

when handling the 12-volt battery:

●

When working with the 12-volt

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

comes into contact with the skin

or eyes, immediately wash the

affected area with water and

seek medical attention. Place a

wet sponge or cloth over the

affected area until medical

attention can be received.
