■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the low fuel level warning light (
P.405)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 1.8 gal.
[7.0 L, 1.5 I mp. gal.] when the vehi-
cle is on a level surface. This value
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 600 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

may vary when the vehicle is on a
slope. Add extra fuel when the vehi-
cle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
hybrid vehicles incorporate elec-
tromagnetic shielding, and there-
fore emit approximately the same
amount of electromagnetic waves
as conventional gasoline pow-
ered vehicles or home electronic
appliances.
●Your vehicle may cause sound
interference in some third
party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery)
has a limited service life. The lifes-
pan of the hybrid battery (traction
battery) can change in accordance
with driving style and driving condi-
tions.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C]) under
the influence of t he outside tem-
perature, it may no t be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increasing, etc.
WARNING
■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a
12-volt system. DC and AC high
voltage is very dangerous and
can cause severe burns and elec-
tric shock that may result in death
or serious injury.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the warning labels
attached to the vehicle.
●Never try to open the service
plug access hole located under
the right side o f the rear seat.
The service plug is used only
when the vehicle is serviced
and is subject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Pull your vehicle off the road,
apply the parking brake, shift
the shift lever to P, and turn the
hybrid system off.
●Do not touch the high voltage
parts, cables and connectors.
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●If a fire occurs in the hybrid
vehicle, leave the vehicle as
soon as possible. Never use a
fire extinguisher that is not
meant for electric fires. Using
even a small amount of water
may be dangerous.

For safety and security
WARNING
●If your vehicle needs to be
towed, do so with the four
wheels raised. If the wheels
connected to the electric motor
(traction motor) are on the
ground when towing, the motor
may continue to generate elec-
tricity. This may cause a fire.
(
P.397)
●Carefully inspect the ground
under the vehicle. If you find
that liquid has leaked onto the
ground, the fuel system may
have been damaged. Leave the
vehicle as soon as possible.
●Do not touch the battery if liquid
is leaking from or adhering to it.
If electrolyte (carbonic-based
organic electrolyte) from the
hybrid battery (traction battery)
comes into contact with the
eyes or skin, it could cause
blindness or skin wounds. In the
unlikely event that it comes into
contact with the eyes or skin,
wash it off immediately with a
large amount of water, and seek
immediate medical attention.
●If electrolyte is leaking from the
hybrid battery (traction battery),
do not approach the vehicle.
Even in the unlikely event that
the hybrid battery (traction bat-
tery) is damaged, the internal
construction of the battery will
prevent a large amount of elec-
trolyte from leaking out. How-
ever, any electrolyte that does
leak out will give off a vapor.
This vapor is an irritant to skin
and eyes and could cause acute
poisoning if inhaled.
●Do not bring burning or
high-temperature items close to
the electrolyte.
The electrolyte may ignite and
cause a fire.
■Hybrid battery (traction bat-
tery)
●Your vehicle contains a sealed
lithium-ion battery.
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly col-
lected, the following may occur,
resulting in dea th or serious
injury:
• The hybrid batte ry may be ille-
gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
hybrid vehicle. If the hybrid bat-
tery is used out side of your
vehicle or modified in any way,
accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of an
accident is extremely high
because the person receiving the
vehicle may not be aware of these
dangers.

741-4. Hybrid system
There is an air intake vent under
the left side of the rear seat with
the purpose of cooling the
hybrid battery (traction battery).
If the vent becomes blocked, it
may interfere with the cooling of
the hybrid battery (traction bat-
tery).
If input/output of the hybrid bat-
tery (traction battery) becomes
limited and the distance that the
vehicle can be driven using the
electric motor (traction motor) is reduced, the fuel economy may
be reduced.
When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
WARNING
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in death or serious
injury.
NOTICE
■Hybrid battery (traction bat-
tery)
Do not carry large amounts of
water such as water cooler bottles
in the vehicle. If water spills onto
the hybrid battery (traction bat-
tery), the batte ry may be dam-
aged. Have the vehicle inspected
by your Toyota dealer.

battery) air intake vent
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Make sure not to block the air
intake vent with anything, such
as a seat cover, plastic cover, or
luggage.
The input/output of the hybrid
battery (traction battery) may be
restricted, leading to a reduction
in hybrid battery (traction bat-
tery) output and a malfunction.
●Periodically clean the air intake
vent to prevent it from clogging.
(  P.379)
●Do not allow liquid or foreign
material to enter the air intake
vent as this may cause a short
circuit and damage the hybrid
battery (traction battery).
