■

Starting the hybrid system

when the battery is discharged

The hybrid system cannot be started

by push-starting.

■

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.581)

■

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

●

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.536). 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.

●

Some systems may require initial-

ization. (



P.581)

■

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 (LN2),

20 hours rate capacity (20HR) is

equivalent (55Ah) or greater, and

performance rating (CCA) is

equivalent (345A) 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

●

Use a 12-volt battery with a han-

dle. If a 12-volt battery without a

handle is used, removal is more

●

After replacing, firmly attach the

following items to the exhaust hole

of the 12-volt battery.

• Use the exhaust hose that was

attached to the 12-volt battery

before replacing and confirm that

it is firmly connected to the hole

section of the vehicle.

• Use the exhaust hole plug

included with the 12-volt battery

replaced or the one installed on

the battery prior to the replaced.

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.

12-volt battery.

■

After recharging the 12-volt

battery

Have the 12-volt battery

inspected at your Toyota dealer

as soon as possible. If the 12-volt

battery is deteriorating, continued

use may cause the 12-volt battery

to emit a malodorous gas, which

may be detrimental to the health

of passengers.

■

When replacing the 12-volt

battery

●

For information regarding 12-

volt battery replacement, con-

tact your Toyota dealer.

●

After replacing, securely attach

the exhaust hose and exhaust

hole plug to the exhaust hole of
