For safety and security
Exhaust gas precau-
tions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases contain harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in
the vehicle even when the back
door is closed, open the side
windows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time.
If such a situation cannot be
avoided, park the vehicle in an
open space and ensure that
exhaust fumes do not enter the
vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem operating, exhaust gases
may collect and enter the vehi-
cle.
■Exhaust pipe
The exhaust system needs to be
checked periodically. If there is a
hole or crack caused by corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

541-2. Child safety
■When installing a child
restraint system to a front
passenger seat
For the safety of a child, install
child restraint system to a rear
seats. When installing child
restraint system to a front pas-
senger seat is unavoidable,
adjust the seat as follows and
install the child restraint system.
 Adjust the seatback angle to
the most upright position.
 Move the front seat fully rear-
ward.
 Move the seat to the upper-
most position
 If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
Otherwise, put the head
restraint in the upper most
position.
When using a child
restraint systemWARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Never install a re ar-facing child
restraint system on the front
passenger seat even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated. In
the event of an accident, the
force of the rapid inflation of the
front passenger airbag can
cause death or serious injury to
the child if the rear-facing child
restraint system is installed on
the front passenger seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.

551-2. Child safety
1
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.

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.

872-1. Plug-in hybrid system
2
Plug-in hybrid system
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
refuel” is displayed on the multi-
information display when the
power switch is turned to ON. If
the message is displayed, refuel
the vehicle immediately.
