For safety and security
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P. 6 9 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).
■When braking (regenera-
tive braking)
The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.
■Regenerative braking
In the following si tuations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with the
recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released
while driving with the shift lever in
D or B.
●The brake pedal is depressed
while driving with the shift lever in
D or B.
■EV indicator
The EV indicator comes on when the vehicle is driven using only the
electric motor (traction motor) or the
gasoline engine is stopped.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it may
not stop automatic ally in the follow-
ing conditions:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the heater is switched on
Depending on the circumstances,
the gasoline engine may also not
stop automatically in other situa-
tions.
■Charging the hybrid battery
(traction battery)
As the gasoline engine charges the
hybrid battery (trac tion battery), the
battery does not need to be charged
from an outside source. However, if
the vehicle is left parked for a long
time the hybrid battery (traction bat-
tery) will slowly dis charge. For this
reason, be sure to drive the vehicle
at least once every few months for
at least 30 minutes or 10 miles (16
km). If the hybrid battery (traction
battery) becomes fully discharged
and you are unabl e to start the
hybrid system, contact your Toyota
dealer.
■Charging the 12-volt battery

For safety and security
There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the
hybrid battery (traction battery).
If the vent becomes blocked, the
hybrid battery may overheat,
charging/discharging of the
hybrid battery (traction battery)
may become limited.
WA R N I N G
●If your vehicle needs to be
towed, do so with the front
wheels raised. If the wheels
connected to the electric motor
(traction moto r) are on the
ground when towing, the motor
may continue to generate elec-
tricity. This may cause a fire.
(  P.445)
●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.
■Hybrid battery (traction bat-
tery)
●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 battery 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 outside 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.
●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 dea th or serious
injury.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
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 battery may be dam-
aged. Have the vehicle inspected
by your Toyota dealer.

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,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.
■If a warning light comes on, a
warning message
is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Make sure that the air intake
vent is not blocked, such as by
a seat cover, plastic cover, or
luggage. If the vent is blocked,
charging/discharging of the
hybrid battery (traction battery)
may become limited, possibly
leading to a malfunction.
●Clean the air intake vent regu-
larly to prevent the hybrid bat-
tery (traction battery) from
overheating.
●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).
●A filter is installed to the air
intake vent. Wh en the filter
remains noticeably dirty even

tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag, etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be s hown on the
multi-information display when the
hybrid system is stopped.
●To reduce key battery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. ( P. 1 1 3 )
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary. ( P.431)
• The smart key system or the wire-
less remote contro l does not oper-
ate.
• The detection area becomes
smaller.
