Key of letters inserted in the above table:
X: Not suitable seat position for children in this mass group.
U: Suitable for “universal” category child restraint systems approved
for use in this mass group.
UF: Suitable for forward-facing “universal” category child restraint sys-
tems approved for use in this mass group.
L: Suitable for “specific vehicles”, “restricted”, or “semi-universal”,
category child restraint systems approved for use in this mass
group.
*1: Adjust the seatback angle to the most upright position. Move the front seat
fully rearward. If the passenger seat height can be adjusted, move it to the
upper most position.
*2: If the head restraint interferes with your child restraint system, and the
head restraint can be removed, remove the head restraint.
Otherwise, put the head restraint in the upper most position.
When securing some types of child restraint systems in rear seat, it
may not be possible to properly use the seat belts in positions next
to the child restraint without interfering with it or affecting seat belt
effectiveness. Be sure your seat belt fits snugly across your shoul-
der and low on your hips. If it does not, or if it interferes with the
child restraint, move to a different position. Failure to do so may
result in death or serious injury.
The child restraint systems mentioned in the table may not be avail-
able outside the EU area.
● When installing a child restraint in the rear seats, adjust the front
seat so that it does not interfere with the child or child restraint
system.
● When installing a child seat with support base, if the child seat
interferes with the seatback when latching it into the support
base, adjust the seatback rearward until there is no interference.

■ After the 12-volt battery has discharged or when the terminal has been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) behind the
rear seats when the hybrid system starts or stops.
● Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent on the side of the
lower part of the rear left seats.
■ Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer regarding maintenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
■ Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.

WARNING
■High voltage precautions
This 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 warning labels attached to the vehicle.
■ Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
● 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.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● Never try to open the service plug
access hole located underneath the
rear seats. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
