When trouble arises
If you have a set of jumper (or
booster) cables and a second
vehicle with a 12-volt battery,
you can jump start your vehicle
by following the steps below.
1Vehicles with alarm system:
Confirm that the electronic
key is being carried.
When connecting the jumper (or
booster) cables, depending on the
situation, the ala rm may activate and the doors locked. (
P.83)
2 Open the hood ( P.398) and
fuse box cover.
Push claws and to com-
pletely release the lock, and then lift
up the cover.
3 Open the exclusive jump
starting terminal cover.
4 Connect a positive jumper cable clamp to on your vehicle and
connect the clamp on the other end of the positive cable to on
the second vehicle. Then, connect a negative cable clamp to
If the 12-volt battery is
discharged
The following procedures
may be used to start the
hybrid system if the vehi-
cle’s 12-volt battery is dis-
charged.
You can also call your
Toyota dealer or a qualified
repair shop.

5 Start the engine of the sec-
ond vehicle. Increase the
engine speed slightly and
maintain at that level for
approximately 5 minutes to
recharge the 12-volt battery
of your vehicle.
6 Vehicles without smart key
system: Maintain the engine
speed of the second vehicle
and start the hybrid system of
your vehicle.
Vehicles with smart key sys-
tem: Maintain the engine
speed of the second vehicle
and start the hybrid system of your vehicle by turning the
power switch to ON.
7 Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.
8 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were
connected.
9 Close the exclusive jump
starting terminal cover, and
reinstall the fuse box cover to
its original position.

4887-2. Steps to take in an emergency
Use a battery that the case size is
same as the previous one (LN1), 20
hours rate capacity (20HR) is equiv-
alent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent
(286A) or greater.
Type C:
Use a battery that the case size is
same as the previous one (LN2), 20
hours rate capacity (20HR) is equiv-
alent (55Ah) or greater, and perfor-
mance 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 t ype calcium bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt b attery without a
handle is used, removal is more
difficult.
●When removing the 12-volt bat-
tery: P.408
●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 an d confirm that
it is firmly connected to the hole
section of t he vehicle.
• Use the exhaust hole plug included with the new 12-volt bat-
tery or the one installed on the
battery prior to t he replacement.
(Depending on the new 12-volt
battery installed, the exhaust hole
may be plugged.)
For details, consult your Toyota
dealer. Exhaust hole

WARNING
■When removing the 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 ele ctrical 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.

When trouble arises
WARNING
●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 corrosi ve 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.
●Always wash your hands after
handling the 12-volt battery sup-
port, terminals, and other bat-
tery-related parts.
●Do not allow child ren near the
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 deteriorat-
ing, continued use may cause the
12-volt battery to emit a malodor-
ous gas, which may be detrimen-
tal to the health of passengers.
■When replacing the 12-volt
battery
●For information regarding 12-
volt battery rep lacement, con-
tact your Toyota dealer.
●After replacing, s ecurely attach
the exhaust hose and exhaust
hole plug to the exhaust hole of
the replaced 12-volt battery. If
not properly installed, gases
(hydrogen) may leak into the
vehicle interior, and there is the
possible danger of the gas ignit-
ing and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper
cables, ensure that they do not
become entangled in the cooling
fan, etc.
■To prevent damaging the
vehicle
The exclusive jump starting termi-
nal 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.
