Prius Plug-in Hybrid_OM_OM47D72E_(EE)
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 hypo-
thermia, or could result in death or serious injury.
● Depending on the surrounding environment, signals from the wireless
switch may transmit further than expected. Pay appropriate attention to
the vehicle’s surroundings and use the switch only when necessary.
● 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
Use “A/C” only when necessary.

Maintenance and care
WARNING
■ Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
■ To prevent burns
■ After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
■ When closing the hood
NOTICE
■When closing the hood
Be sure to return the supporting rod to its clip before closing the hood. Clos-
ing the hood without returning the support rod properly could cause the
hood to bend.
Do not touch the air conditioning pipes
when the air conditioning compressor is
operating or after it is stopped, because
the air conditioning pipes are hot.
Touching by hands before the air condi-
tioning pipes cool down may cause
burns.
When closing the hood, take extra care
to prevent your fingers etc. from being
caught.

After stopping the hybrid system and waiting for 5 minutes or
more, start the hybrid system again and check if “Hybrid System
Overheated” is shown on the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the message is not displayed:
The hybrid system temperature has dropped and the vehicle may
be driven normally.
However, if the message appears again frequently, contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
WARNING
■ To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “Accessory”,
“Ignition ON” or mileage display ( P. 223) on the main display and the
“READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
cally start, or the cooling fans 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 reservoir caps while the hybrid system and radi-
ator are hot.
High temperature steam or coolant could spray out.
