7-2. Steps to take in an emergency



M20A-FXS engine

●

Use a Central Degassing type 12-volt battery (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 perfor-
mance rating (CCA) is equivalent (286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If an improper 12-volt battery is used, battery performance may decrease

and the hybrid system may not be able to restart.

• If the 20 hour rate capacity is low, even if the time period where the vehi-

cle is not used is a short time, the 12-volt battery may discharge and the
hybrid system may not be able to start.

●

Use a 12-volt battery with a handle. If a 12-volt battery without a handle is
used, removal is more difficult.

●

After replacing, firmly attach the following items to the exhaust hole of the
12-volt battery.

●

For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

Exhaust hole plug
Exhaust hole
Exhaust hose
• 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  12-volt  bat-
tery  prior  to  the  replacement.
(Depending  on  the  12-volt  battery  to
be replaced, the exhaust hole may be
plugged.)

WARNING

■

When removing the 12-volt battery terminals

Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) 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 flam-
mable gas that may be emitted from the 12-volt battery:

●

Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.

●

Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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 poisonous and corrosive acidic electrolyte,
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 battery.

●

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.

●

Always wash your hands after handling the 12-volt battery support, termi-
nals, and other battery-related parts.

7-2. Steps to take in an emergency

WARNING

■

After recharging the 12-volt battery (M20A-FXS engine)

Have the 12-volt battery inspected at any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer 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

●

When the vent plug and indicator are close to the hold down clamp, the
battery fluid (sulfuric acid) may leak.

●

For information regarding 12-volt battery replacement, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

●

M20A-FXS engine: After exchanging, securely attach the exhaust hose
and exhaust hole plug to the exhaust hole of the exchanged 12-volt bat-
tery. If not properly installed, gases (hydrogen) may leak into the vehicle
interior, and there is the possible danger of the gas igniting and exploding.

NOTICE

■

When handling jumper cables

When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans, etc.

■

To prevent damaging the vehicle (M20A-FXS engine)

The exclusive jump starting terminal is to be used when charging the 12-volt
battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.

WARNING

■

To prevent an accident or injury when inspecting under the hood of
your vehicle

Observe the following precautions.
Failure to do so may result in serious injury such as burns.

●

If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.

●

After the hybrid system has been turned off, check that the indicator on the
power switch and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally start, or the cooling fans may suddenly operate even if the gasoline
engine stops. Do not touch or approach rotating parts such as the fan,
which may lead to fingers or clothing (especially a tie, a scarf or a muffler)
getting caught, resulting in serious injury.

●

Do not loosen the coolant reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.

NOTICE

■

When adding engine/power control unit coolant

Add coolant slowly after the hybrid system has cooled down sufficiently.
Adding cool coolant to a hot hybrid system too quickly can cause damage to
the hybrid system.

■

To prevent damage to the cooling system

Observe the following precautions:

●

Avoid contaminating the coolant with foreign matter (such as sand or dust,
etc.).

●

Do not use any coolant additive.
