WARNING
■Front passenger occupant classi fication system precautions
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator
light is illuminated. If the “AIR BAG OFF” indicator is illuminated, ask the
passenger to sit up straight, well back in the seat, feet on the floor, and
with the seat belt worn correctly. If the “AIR BAG OFF” indicator still
remains illuminated, either ask the passenger to move to the rear seat, or
if that is not possible, move the front passenger seat fully rearward.
● When it is unavoidable to install a forward-facing child restraint system on
the front passenger seat, install the child restraint system on the front pas-
senger seat in the proper order. ( →P. 58)
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Other-
wise, the SRS warning light may come on to indicate a malfunction of the
front passenger occupant classification system. In this case, contact your
Toyota dealer immediately.
● Child restraint systems installed on the rear seat should not contact the
front seatbacks.
● Do not use a seat accessory, such as a cushion and seat cover, that cov-
ers the seat cushion surface.
● Do not modify or replace the upholstery of the front seat.
● Adjust the front passenger seat so that the head restraint does not touch
the ceiling. If the head restraint is left in contact with the ceiling, the system
may not detect the front passenger properly, leading to improper operation
of the airbags.

Riding with children
●It is recommended that children sit in the rear seats to avoid acci-
dental contact with the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the
power window accidentally. ( →P. 270, 300)
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, back door,
seats etc.
Observe the following precautions when children are in the vehi-
cle.
Use a child restraint system appropriate for the child, until the
child becomes large enough to pr operly wear the vehicle’s seat
belt.
WARNING
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neut\
ral.
There is also a danger that children may injure themselves by playing with
the side windows or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures inside the vehicle can be fatal to childr\
en.

2-1. Plug-in hybrid system
■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(→P. 587)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, 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 vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, suc\
h
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.
■ 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 position 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) 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. ( →P. 91)
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
● In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.

2-2. Charging
WARNING
■If the error warning indicator on the CCID (Charging Circuit Interrupt-
ing Device) illuminates or flashes during charging
There may be an electrical leakage in the power source path, or there may
be a malfunction in the charging cable or CCID (Charging Circuit Interr\
upt-
ing Device). Refer to P. 110 and follow the correction procedure. If the error
warning indicator does not turn off even after performing the correction pro-
cedure, immediately stop charging, remove the charging cable and contact
your Toyota dealer. Continuing to charge the vehicle in that condition may
lead to unforeseen accidents or serious injury.
■ After charging
Remove the plug if it will not be used for a long time.
Dirt and dust may accumulate plug or outlet, which could cause a malfunc-
tion or fire, possibly leading to death or serious injury.
■ Charging equipment
There is charging equipment under the rear seats. Make sure to observe
the following precautions regarding the charging equipment. Failure to
observe these precautions may result in death or serious injury such as
burns and electric shocks.
● The charging equipment is hot during charging. Do not touch the charging
equipment, as doing so may result in burns.
● Do not disassemble, repair or modify the charging equipment.
When the charging equipment needs to be repaired, consult your Toyota
dealer.
