501-2. Child safety
1-2.Child safety
Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the shift lever, wiper
switch, etc.
 Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.189, 229)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
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
neutral. There is also a danger
that children ma y injure them-
selves 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
children.

1102-2. Charging
■“Battery Cooler”
●The charging indicator is illumi-
nated while “Battery Cooler” is on
standby or operating.
●“Battery Cooler” is implemented
for a maximum of approximately
30 minutes.
●When there is a small amount of
remaining charge in the hybrid
battery (traction battery), even if
the hybrid battery (traction battery)
is hot, “Battery Cooler” may not be
implemented.
●When the hybrid battery (traction
battery) is almost completely
charged, “Battery Cooler” may not
be implemented.
●When the following operations are
performed while “Battery Cooler”
is operating, the hybrid battery
(traction battery) cooling operation
stops.
• The hood is opened
• The power switch is turned to any mode other than off
• “Charge Now” is implemented ( P.124)
●“Battery Cooler” uses the power of
the hybrid battery (traction battery)
and external power source.
• While “Battery Cooler” is operat- ing, the remaining charge of the
hybrid battery ma y not increase
the same amount as during nor-
mal charging.
• The operation of “Battery Cooler”
is recognized as charging by a
charger. The charger that calcu-
lates the fee according to charging
time causes a charging fee.
To enable the use of EV mode
or AUTO EV/HV mode, we rec-
ommend systematically
charging the vehicle.
■Before leaving home
In order to use EV mode or
AUTO EV/HV mode, charge the
hybrid battery (traction battery)
at home before leaving.
■At your destination
Use a public charging station to
charge the hybrid battery (trac-
tion battery).
If there are no charging facilities
at your destination, the hybrid
battery (traction battery) can be
charged using the hybrid battery
(traction battery) charge mode.
( P.75)

This section explains meth-
ods for using the charging
function for this vehicle and
checking information
related to charging.

1894-2. Opening, closing and locking the doors
4
Before driving
message will be displayed on the
multi-information display for approx-
imately 6 seconds.
Also, as the second reminder, when
the doors are locked, a buzzer will
sound and the emergency flashers
will flash for a few seconds, and a
message will be displayed on the
multi-information display.
●The hybrid system is started
within approximately 10 minutes
after opening and closing a rear
door.
●A rear door has been opened and
closed after the hybrid system
was started.
The second reminder will not be
activated if a rear door was opened
before the doors are locked.
However, if a rear door is opened
and then closed within approxi-
mately 2 seconds, the rear seat
reminder function may not operate.
The rear seat reminder function
determines that luggage, etc. has
been placed in a rear seat based on
opening and closing of a rear door.
Therefore, depending on the situa-
tion, the rear seat reminder function
may not operate and you may still
forget luggage, etc. in the rear seat,
or it may operate unnecessarily.
■Open door warning buzzer
If the vehicle speed reaches 3 mph
(5 km/h), a buzzer sounds to indi-
cate that the door(s) or the hood is
not fully closed.
The open door(s) or hood is dis-
played on the multi-information dis-
play.
■Customization
The rear seat reminder function can
be enabled/disabled. (Customiz-
able features: P.618)The door cannot be opened
from inside the vehicle when the
lock is set.
WARNING
■To prevent an accident
Observe the following precautions
while driving the vehicle.
Failure to do so may result in a
door opening and an occupant
could be thrown out of the vehicle,
resulting in death or serious
injury.
●Ensure that all doors are prop-
erly closed and locked.
●Do not pull the inside handle of
the doors while driving.
Be especially careful for the
front doors, as the doors may
be opened even if the inside
lock buttons are in locked posi-
tion.
●Set the rear door child-protector
locks when children are seated
in the rear seats.
■When opening or closing a
door
Check the surroundings of the
vehicle such as whether the vehi-
cle is on an incline, whether there
is enough space for a door to
open and whether a strong wind
is blowing. When opening or clos-
ing the door, hold the door handle
tightly to prepare for any unpre-
dictable movement.

4726-4. Using the other interior features
Observe the following precau-
tions before starting the power
supply:
Park the vehicle in a well-ven-
tilated area, avoiding loca-
tions with poor ventilation
such as garages, as the
engine may start while the
system is operating.
 Park the vehicle on a solid
and level place.
Block the wheels as needed.
Check that the hood is closed.
 Check that the parking brake
is engaged.
 Check that the shift position is
in P.
 Check that the power switch
is off.
 Note that the alarm system
WARNING
• When a device is likely to fall
under the pedals and prevent
the brake pedal from being
depressed, such as a hair dryer,
AC adapter, mouse, etc.
●Do not use devices which pro-
duce steam while the windows
are closed. Doing so may cause
the windows to fog up, reducing
visibility and making it difficult to
drive safely. Also, the steam
may damage or negatively
affect other devices. If the
device must be used, stop the
vehicle and open the windows
before use.
NOTICE
■To avoid short circuit or mal-
function
Observe the following precau-
tions. Failure to do so may lead to
the power outlets not operating
correctly or damage to the vehicle
or a connected device.
●Do not set a toaster or other
device which generates heat
near the interior components or
on a seat. Heat may cause
these parts to melt or burn.
●Do not use devices which are
sensitive to vibration or heat in
the vehicle. These devices may
malfunction due to vibration
while driving or heat while the
vehicle is parked in the sun.
●When not using a power outlet,
make sure to close the lid. If for-
eign matter or a liquid enters the
power outlet, it may cause a
malfunction or short circuit.
■Using the power outlet while
parked or stopped
●Water may leak from the
exhaust pipe while the engine
running if the power outlet is
used for a long time. However,
this is not a malfunction.
●At extremely low temperatures,
water may freeze in the exhaust
pipe and make it difficult to start
the engine, or an odor may
come from the exhaust pipe. In
this case, stop using the power
outlet, and then drive the vehi-
cle for 15 to 30 minutes.

power outlets while
parked

WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions.
Failure to do so may result in seri-
ous injury such as burns.
●If steam is seen coming from
under the hood, do not open the
hood until the steam has sub-
sided. The engine compart-
ment may be very hot.
●After the hybrid system has
been turned off, check that the
“READY” indicator is off.
When the hybrid system is oper-
ating, the gasoline engine may
automatically start, or the cool-
ing fan may suddenly operate
even if the gasoline engine
stops. Do not touch or approach
rotating parts such as the fan,
which may lead to fingers or
clothing (especially a tie, a scarf
or a muffler) getting caught,
resulting in serious injury.
●Do not loosen the coolant reser-
voir cap while th e hybrid system
and radiator are hot.
High temperature steam or
coolant could spray out.
NOTICE
■When adding engine/power
control unit coolant
Add coolant slowly after the
hybrid system has cooled down
sufficiently. Adding cool coolant to
a hot hybrid system too quickly
can cause damage to the hybrid
system.
