601-2. Child safety
■Child restraint LATCH
anchors
LATCH anchors are provided for
the outboard rear seats. (Marks
displaying the location of the
anchors are attached to the seats.)
■When installing in the rear
outboard seats
Install the child restraint system
in accordance to the operation
manual enclosed with the child
restraint system.
1 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
( P.212)
With flexible lower attach-
ments
2 Remove the anchor covers,
and latch the hooks of the
lower attachments onto the
LATCH anchors.
For owners in Canada:
The symbol on a child
restraint system indicates
WARNING
●When securing some types of
child restraint systems in rear
seats, it may not be possible to
properly use the seat belts in
positions next to the child
restraint without interfering with
it or affecting se at belt effective-
ness. Be sure your seat belt fits
snugly across your shoulder
and low on your hips. If it does
not, or if it interferes with the
child restraint, mo ve to a differ-
ent position. Failure to do so
may result in death or serious
injury.
■When installing a booster
seat
To prevent the belt from going
into ALR lock mode, do not fully
extend the shoulder belt. ALR
mode causes the belt to tighten
only. This could cause injury or
discomfort to the child. ( P.33)
■Do not use a seat belt
extender
If a seat belt extender is used
when installing a child restraint
system, the seat belt will not
securely hold th e child restraint
system, which could cause death
or serious injury to the child or
other passengers in the event of
sudden braking, sudden swerv-
ing or an accident.

Plug-in hybrid system
The plug-in hybrid system oper-
ates in the following modes.
The meter display can be used to
check which mode the plug-in
hybrid system is currently being
driven in. (P.150)
■EV mode
When a sufficient amount of
electricity is remaining after
charging
*1, EV driving is per-
formed using electricity stored in
the hybrid battery (traction bat-
tery).
*2
When in EV mode, the EV drive
mode indicator illuminates.
*1: The amount of remaining charge can be checked on the SOC
(State of Charge) gauge.
( P.155)
*2: Depending on the situation, EV
driving may be canceled and
both gasoline engine and electric
motor are used. ( P.79)
■AUTO EV/HV mode
Normally, the electricity stored
in the hybrid battery (traction
battery) is used for EV driving.
However, when more power is
required, such as for driving
uphill or accelerating suddenly,
the gasoline engine starts and
provides powerful acceleration
by strongly depressing the
accelerator pedal.
When the vehicle is in a condi-
tion where EV driving is possi-
ble, EV mode and AUTO EV/HV
mode can be switched by oper-
ating the switch. ( P.74)
When in AUTO EV/HV mode, the
AUTO EV/HV mode indicator illumi-
nates.
■HV mode
When in HV mode, the vehicle is
driven using both the gasoline
Plug-in hybrid system

762-1. Plug-in hybrid system
from an external power source.
■If the plug-in hybrid system
operation mode cannot be
changed
In the following situations, the plug-
in hybrid system operation mode
cannot be changed even if the
AUTO EV/HV mode switch or
EV/HV mode selection switch is
pressed. (In this case, the warning
message is displayed on the multi-
information displa y when the switch
is pressed.)
●When electricity needed for EV
driving is not remaining (when in
EV mode or AUTO EV/HV mode)
●When the hybrid battery (traction
battery) is almost completely
charged (hybrid battery [traction
battery] charge mode)
■When switching from EV mode
to another mode using the
switch
When the power switch is turned off,
operation mode switching is can-
celed and the system returns to EV
mode the next time the vehicle is
started.
*
*
: If there is not enough charge remaining in the hybrid battery
(traction battery) to allow EV driv-
ing, the system switches to HV
mode.
■Hybrid battery (traction battery)
charge mode
●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or
cannot cancel it
• Gasoline engine does not start or stops even after switching to
hybrid battery (traction battery)
charge mode
●If a load to the system is large,
such as when the power con-
sumption of the air conditioning
system is large or when the tem-
perature of the engine coolant is
high, it may take longer time than
usual to charge using the hybrid
battery (traction battery) charge
mode, or charging to the hybrid
battery (traction battery) may not
be performed.
■When in EV mode
In EV mode, EV driving (driving
WARNING
■When using the hybrid bat-
tery (traction battery) charge
mode
Observe the following precautions
when using the hybrid battery
(traction battery) charge mode
while parking.
Failure to do so may lead to death
or serious health hazard, as the
gasoline engine operates when in
the hybrid battery (traction bat-
tery) charge mode.
●Do not stop the vehicle near
flammable materials.
●Do not use the hybrid battery
(traction battery) charge mode
in a closed area where ventila-
tion is insufficient, such as in a
garage or area with snow
buildup.
Control when driving in
each mode

782-1. Plug-in hybrid system
When the accelerator pedal is
depressed heavily, drive force
from both the gasoline engine
and the electric motor (trac-
tion motor) is used to acceler-
ate.
*: When the hybrid battery (traction
battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P.79)
■When braking (regenera-
tive braking)
The electric motor (traction
motor) charges the hybrid bat-
tery (traction battery).
The EV driving range can be
extended by actively using this
regenerative braking to store
electricity in the hybrid battery
(traction battery).
Moreover, as fuel consumption
is also reduced when in HV
mode, the regenerative braking
system can be used effectively.
■Regenerative braking
●In the following situations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with
the recharging of the hybrid bat-
tery (traction battery).
• The accelerator pedal is released while driving with the shift position
in D or B.
• The brake pedal is depressed while driving with the shift position
in D or B.
●The Regeneration Boost oper-
ates when the shift position is
shifted to B. The regenerative
braking force can be changed when the Regeneration Boost is
operating. (
P.260)
■EV driving range
●The EV driving range is displayed
on the meter. ( P.155)
●The EV driving range changes in
accordance with the charge status
of the hybrid battery (traction bat-
tery), the speed of the vehicle, etc.
●Even if there is enough charge
remaining in the hybrid battery
(traction battery), EV driving may
be canceled and both gasoline
engine and electric motor are
used depending on the situation.
( P.79)
■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.
The on/off operation of the EV indi-
cator can be changed. ( P.166)
■After EV mode has switched to
HV mode due to low hybrid bat-
tery (traction battery) charge
If the hybrid battery (traction battery)
is regenerated by driving continu-
ously down a long slope, the EV
driving range etc. will be displayed
on the meter an d EV mode will be
automatically switched to.
If EV mode is not switched to even
though EV driving range is being
displayed, EV mode can be
switched to by pressing the EV/HV
mode selection switch.

■Gasoline engine operation in
EV mode or AUTO EV/HV mode
Even if there is a sufficient amount
of electricity remain ing in the hybrid
battery (traction battery) and EV
driving range ( P.155) is being dis-
played on the meter, EV driving
(driving using only the electric
motor) may be canceled and both
gasoline engine and electric motor
are used depending on the situation
(EV driving will be returned to auto-
matically after EV driving becomes
possible again).
EV driving may be canceled auto-
matically in the following circum-
stances
*1:
●When vehicle speed is more than
approximately 84 mph (135 km/h).
●When power is needed temporar-
ily, for example when the acceler-
ator pedal is depressed firmly or
when accelerating suddenly.
*2
●When the temperature of the
hybrid system is high.
The vehicle has been left in the
sun, driven on a h ill, driven at high
speeds, etc.
●When the temperature of the
hybrid system is low.
●When the heater is switched on
when the outside temperature is
below about 14°F (-10°C).
●When the windshield defogger
switch is pressed. ( P.434)
●When the system determines that
the gasoline engine needs to be
started.
*1: The gasoline engine may also
operate in circumstances other
than those listed above, depend-
ing on conditions.
*2: When driving in AUTO EV/HV mode. Even in EV mode, the gas-
oline engine may start, depend-
ing on the condition of the hybrid
battery (traction battery).
■If “Engine Started to Protect
System EV driving unavailable”
is displayed on the multi-infor-
mation display
EV driving may be canceled in order
to protect the hybrid system, etc.
In this case, perform driving with the
gasoline engine until EV driving will
be returned to automatically.
Depending on the conditions, driv-
ing that combines the use of the
gasoline engine may continue for a
short while. However, this is not a
malfunction.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically . However, it
may not stop automatically in the
following 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 windshield defogger
switch is pressed. ( P.434)
*: Depending on the circumstances,
the gasoline engine may also not
stop automatically in situations
other than those above.
■Sounds and vibrations specific
to a Plug-in Hybrid Electric
Vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
Plug-in Hybrid Electric Vehicle for
being off when it is actually still run-
ning, as indicated by the “READY”
indicator being illuminated. For
safety, make sure to always shift the
shift position to P and apply the
parking brake when parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion.

812-1. Plug-in hybrid system

Plug-in hybrid system
charge the hybrid battery (traction
battery) from external power
source or start the hybrid system
at least once every 2 or 3 months,
and turn the power switch off after
the gasoline engine has stopped
automatically. (If the gasoline
engine does not start up even
after approximately 10 seconds
have passed since the “READY”
indicator came on, the power
switch can be turned to off without
any further action.)
When the 12-volt battery is dis-
charged, refer to P.589, “If the 12-
volt battery is discharged” and
perform the correction procedure.
●When the vehicle is left with the
AC charging cable connected, the
electricity consumption amount of
the 12-volt battery increases due
to controls, such as the system
checking, operating. When the AC
charging cable is not needed,
remove it from the vehicle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the Acoustic Vehicle Alert- ing System is installed on the front
of the vehicle, it may be more diffi-
cult to hear from the rear of the vehi-
cle compared to the front.
■When “Acoustic Vehicle Alert-
ing System Malfunction Visit
your Dealer” is displayed on the
multi-information display
The Acoustic Vehicle Alerting Sys-
tem may be malfunctioning. Have
the vehicle inspected by your
Toyota dealer immediately.
*: This function can only be used in the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “MULTIME-
DIA OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the refer-
ence operation range ( ) of
the ECO Accelerator Guid-
ance ( P.163) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.

When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks off the high voltage cur-
rent and stops the fuel pump to
minimize the risk of electrocu-
tion and fuel leakage.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the hybrid sys-
tem, contact 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
that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
NOTICE
●If the vehicle has not been refu-
eled for a certain amount of time
and it is possible that the quality
of the fuel remaining in the tank
has changed, “No New Fuel has
been Added Recently Please
