PRIUS PRIME_OM_OM47C77U_(U)
1
For safety and security
Riding with children
●It is recommended that children sit in the rear seats to avoid acci-
dental contact wit h the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switc h to
avoid children opening the door while driving or operating the
power window accidentally. ( P. 282, 312)
● 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 properly 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 neutral.
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 children.

2-2. Charging
■“Traction Battery Cooler”
●When the hybrid battery (traction battery) is above a certain temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Co oler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this s creen, sys-
tem operation becomes possible.
● When charging starts, “Traction Battery Cooler” only operates i f the hybrid
battery (traction battery) temperature is hot.
● The charging indicator is illuminated while “Traction Battery C ooler” is on
standby or operating.
● “Traction Battery Cooler” is implemented for a maximum of approximately
30 minutes. However, when the “Departure” time is set ( P. 157) and there
is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become s horter.
● When there is a small amount of remaining charge in the hybrid battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.
● When the following operations are performed while “Traction Bat tery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.
• A door is opened
• The hood is opened
• The power switch is turned to any mode other than off
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( P. 5 2 2 )
• “Charge Now” is implemented ( P. 1 5 8 )
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
● When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Batt ery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display ( P. 246). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
● “Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of th e remaining
charge of the hybrid battery (traction battery) increases and d ecreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as ch arging by a
charging equipment. The charging equipment that calculates the fee
according to charging time causes a charging fee.

5-5. Using the driving support systems
■If the PCS warning light flashes or illuminates and a warning m essage is
displayed on the multi-information display
The pre-collision system may be temporarily unavailable or ther e may be a
malfunction in the system.
● In the following situations, the warning light will turn off, t he message will
disappear and the system will become operational when normal op erating
conditions return:
• When the radar sensor or camera sensor or the area around eith er sen-
sor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around eith er sen-
sor is cold, such as in an extremely cold environment
• When a front sensor is dirty or covered with snow, etc.
• When the part of the windshield in front of the camera sensor is fogged
up or covered with condensation or ice
(Defogging the windshield: P. 504, 514)
• If the camera sensor is obstructed, such as when the hood is open or a sticker is attached to the windshield near the camera sensor
● If the PCS warning light continues to flash or remains illuminated or the
warning message does not disappear even though the vehicle has returned
to normal, the system may be malfunctioning. Have the vehicle inspected by
your Toyota dealer immediately.

●If VSC is disabled ( P. 491), the pre-collision brake assist and pre-collision
braking functions are also disabled.

Interior features
WARNING
■Precautions for the Remote Air Conditioning System
● Do not use the system if people are in the vehicle.
Even when the system is in use, the internal temperature may st ill reach a
high or low level due to features such as the automatic shut-off. Children
and pets left inside the vehicle may suffer heatstroke dehydration or hypo-
thermia or could result in death or serious injury.
● Depending on the surrounding environment, signals from the wire less
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessa r y.
● Do not operate “A/C” if the hood is open. The air conditioning may operate
unintentionally and objects may be drawn into the electrical cooling fan.
NOTICE
■To prevent the hybrid battery (traction battery) from being discharged
through incorrect operation
