For safety and security
A child restraint system for a
small child or baby must itself be
properly restrained on the seat
with the lap portion of the
lap/shoulder belt.
■Installing child restraint
system using a seat belt
(child restraint lock func-
tion belt)
Install the child restraint system
in accordance to the operation
WARNING
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, adjust the seat-
back angle to the most upright
position, move the seat to the
rearmost position, even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
●Do not allow the child to lean
his/her head or any part of
his/her body against the door or
the area of the seat, front or rear
pillars, or roof side rails from
which the SRS side airbags or
SRS curtain shield airbags
deploy even if the child is
seated in the child restraint sys-
tem. It is dangerous if the SRS
side and curtain shield airbags
inflate, and the impact could
cause death or serious injury to
the child.
●When a booster seat is
installed, always ensure that the
shoulder belt is positioned
across the center of the child’s
shoulder. The belt should be
kept away from the child’s neck,
but not so that it could fall off the
child’s shoulder.
●Use a child restraint system
suitable to the age and size of
the child and install it to the rear
seat.
●If the driver’s seat interferes
with the child restraint system
and prevents it from being
attached correctly, attach the
child restraint system to the
right-hand rear seat.
●Adjust the front passenger seat
so that it does not interfere with
the child restraint system.

buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. (P.31)
■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may spring
up due to the rebound of the seat
cushion. Release the buckle while
holding down the child restraint
system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●Ensure that the belt and plate
are securely locked and the
seat belt is not twisted.
●Shake the child restraint system
left and right, and forward and
backward to ensure that it has
been securely installed.
●After securing a child restraint
system, never adjust the seat.
●When a booster seat is
installed, always ensure that the
shoulder belt is positioned
across the center of the child’s
shoulder. The belt should be
kept away from the child’s neck,
but not so that it could fall off the
child’s shoulder.
●Follow all installation instruc-
tions provided by the child
restraint system manufacturer.

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.

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)

●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.

842-1. Plug-in hybrid system
■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.562)
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 2.1 gal.
[8.0 L, 1.8 Imp.gal.], when the vehi-
cle is on a level surface. This value
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
the Plug-in Hybrid Electric Vehi-
cles incorporate electromagnetic
shielding, and therefore emit
approximately the same amount
of electromagnetic waves as con-
ventional gasoline powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in some third party-
produced radio parts.
■Effect of magnetic forces
If objects that generate strong mag-
netic forces, such as large speak-
ers, are placed inside the luggage
compartment or installed nearby,
the generated magnetic forces may
negatively affect the hybrid system.
■Hybrid battery (traction battery)
(lithium-ion battery)
The hybrid battery (traction battery)
has a limited service life.
The hybrid battery (traction battery)
capacity (the ability to hold a
charge) reduces with time and use
in the same way as other recharge-
able batteries. The extent at which
capacity reduces changes drasti-
cally depending on the environment
(ambient temperature, etc.) and
usage conditions, such as how the
vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of
lithium-ion batteries, and is not a
malfunction. Also, even though the
EV driving range becomes shorter
when the hybrid battery (traction
battery) capacity reduces, vehicle
performance does not significantly
become worse.
In order to reduce the possibility of
the capacity reducing, follow the
directions listed on P.113, “Capacity
reduction of the hybrid battery (trac-
tion battery)”.
■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 the outside tem-
perature, it may not 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 increase etc.
WARNING
■High voltage precautions
The vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
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 caution labels
attached to the vehicle.

WARNING
●Never try to open the service
plug access hole located in the
luggage compartment. The ser-
vice plug is used only when the
vehicle is serviced and is sub-
ject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Stop the vehicle in a safe place
to prevent subsequent acci-
dents. While depressing the
brake pedal, apply the parking
brake and shift the shift position
to P to stop the Plug-in hybrid
system. Then, slowly release
the brake pedal.
●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.
●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.
●If a fire occurs in the Plug-in
Hybrid Electric 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 dan-
gerous.
●If your vehicle needs to be
towed, do so with front wheels
raised. If the wheels connected
to the electric motor (traction
motor) are on the ground when
towing, the motor may continue
to generate electricity. This may
cause a fire. ( P.550)
●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)
●Your vehicle contains a sealed
lithium-ion battery.
