2021 TOYOTA RAV4 PRIME open hood

3145-5. Using the driving support systems
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disapp ear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such as
after the vehicle is parked in an
extremely cold environment, use the
air conditioning system to increase
the temperature around the front
camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc. to clear the obstruction.
SituationActions

4066-1. Using the air conditioning system and defogger
cient due to the power being
restricted more than during normal
air conditioning operation. Also, the
outside of the windshield may fog up
due to the outside temperature,
humidity or air conditioning set tem-
perature.
■Using the heater via the Remote
Air Conditioning System
●When the outside temperature is
low, heating may feel insufficient
due to restricted operation of the
air conditioning.
●When the outside heat exchanger
becomes frosted over, heating
performance may decline due to
automatically switching to the frost
removal operation. ( P.396)
■Security feature
Any unlocked doors will be automat-
ically locked when the system is
operating. The buzzer sounds and
the emergency flashers flash to indi-
cate that the doors have been
locked or the system has been
turned off.
■Conditions affecting operation
 P.218
■While the Remote Air Condi-
tioning System is operating
●Depending on the operating con-
dition of the Remote Air Condition-
ing System, the air conditioning
compressor or cooling fan may
spin and an operating noise may
be heard. However, this does not
indicate a malfunction.
●The air conditioning operation
switches, etc. will not operate
while the Remote Air Condition-
ing System is operating.
■Electronic key battery depletion
 P.194
■When the electronic key bat-
tery is fully depleted
 P.493
■Customization
Setting (e.g. Operation using “A/C”
on the wireless remote control) can
be changed. (Customizable fea-
tures: P.569)
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
still 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
hypothermia or could result in
death or serious injury.
●Depending on the surrounding
environment, signals from the
wireless switch may transmit
further than e xpected. Pay
appropriate attention to the
vehicle’s surroundings and use
the switch only when neces-
sary.
●Do not operate “A/C” on the
wireless remote control if the
hood is open. The Remote Air
Conditioning System may oper-
ate unintentionally and objects
may be drawn into the electrical
cooling fan.
NOTICE
■To prevent the hybrid battery
(traction battery) from being
discharged
Use “A/C” on the wireless remote
control only when necessary.

4246-4. Using the other interior features
WARNING
• Devices which may fall under the pedals and prevent the
brake pedal from being
depressed, such as a hair dryer,
AC adaptor, 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.
●Do not connect a malfunctioning
device to a power outlet, as
doing so may ca use the power
outlet to become inoperable.
●Do not disconnect the plug of a
device while your hands are wet
or insert a pin o r other object
into the pow er outlet. Also, if a
liquid or snow is on the power
outlet, dry the outlet before
using it.
●Be careful not to get pinched by
the power outlet lid.
●Do not attempt to modify, disas-
semble or repair a power outlet.
Also, do not replace the 120
VAC inverter with a commer-
cially available one. For infor-
mation on repairs, contact your
Toyota dealer.
●Do not let children touch the
power outlet.
●Keep the power outlet free of
foreign matter.
●Keep the power outlet free of
dust and foreign matter. Also,
make sure to clean the power
outlet periodically.
●If the plug of a device fits
loosely in a power outlet, even
though it is fully inserted,
replace the power outlet. For
information on replacement,
contact your Toyota dealer.
■Using the power outlet while
parked or stopped
Observe the following precau-
tions.
Failure to do so may lead to an
accident, possibly resulting in
death or serious injury.
●Make sure to securely engage
the parking brake and shift the
shift lever to P.
●Do not leave the vehicle unat-
tended while the READY indica-
tor is illuminated and a device is
connected to a power outlet.
●Make sure that the hood is
closed. As the engine will start
automatically depending on the
condition of the vehicle, make
sure that nothing is left near or
contacting the exhaust pipes.
Also, do not put your head or
hands anywhere inside the
engine compartment, as the
cooling fans may operate sud-
denly. Keep hands and clothing
(especially a tie, scarf, etc.)
away from the fans as they may
get caught in a fan.
●Do not stop the vehicle near
objects which burn easily. If the
exhaust system is extremely
hot, it may cause a fire.

When trouble arises
dropped and the vehicle may be
driven normally.
However, if the message appears
again frequently, contact your
Toyota dealer.
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 the 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.
■To prevent damage to the
cooling system
Observe the following precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust, etc.).
●Do not use any coolant additive.
