WARNING
■When installing a child restraint system
Observe the following precautions.
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 inju-
ries 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 instructions provided by the child restraint system
manufacturer.
■ 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. 31)
■ 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 the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of sud-
den braking, sudden swerving or an accident.

■Switching to the hybrid battery (traction battery) charge mode
Press and hold the switch.
Take your hand off the switch
once the hybrid battery charge
mode indicator starts to blink.
The hybrid battery charge mode
indicator illuminates when the
switch to hybrid battery (traction
battery) charge mode is com-
plete.
When the hybrid battery (traction battery) is fully charged
*, the hybrid
battery (traction battery) charge mode is automatically canceled and the
operation mode will be switched to HV mode.
The hybrid battery (traction battery) charge mode will be canceled by
pressing EV/HV mode selection switch or EV auto mode switch.
*: The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
■ If the plug-in hybrid system op eration mode cannot be changed
In the following situations, the plug-in hybrid system operation mode cannot
be changed even if the EV/HV mode selection switch or EV auto mode switc\
h
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
● When electricity needed for EV driving is not remaining (when in EV/EV
auto mode)
● When the traction battery is almost completely charged (hybrid battery [trac-
tion 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 canceled
and the system returns to EV mode the next time the vehicle is started.
■ Hybrid battery (tractio n 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 bat- tery (traction battery) charge mode
● If a load to the system is large, such as when the power consumption of \
the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.

■Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
WARNING
■When using the hybrid battery (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 battery) 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 ventilation is insufficient, such as in a garage or area with
snow buildup.

There are air intake vents on both
sides of the rear seatback for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vents
become blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading to a reduction in
hybrid battery (traction battery)
output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leak-
age. If the emergency shut off syst em activates, your vehicle will not
restart. To restart the hybrid system, contact your Toyota dealer.
A message is automatically displa yed 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 disconnected
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.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel le\
vel
warning light ( →P. 655) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
2.0 gal. [7.5 L, 1.7 Imp.gal.], when the vehicle is on a level surface. \
This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore em it approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction ba ttery) (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 rechargeable batteries.
The extent at which capacity reduces changes drastically 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 malfunc-
tion. Also, even though the distance that can be driven in EV mode decreases
when the hybrid battery (traction battery) capacity reduces, vehicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the \
directions
listed on P. 133, “Capacity reduction of the hybrid battery (traction battery)”.
■ Starting the hybrid system in an extremely cold environment
When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -22° F [-30°C]) under the influence of the outside temperature, 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 sys-
tem. DC and AC high voltage 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 voltage parts,
cables or their connectors.
● 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.
●Never try to open the service plug
access hole located in the luggage
compartment. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
