781-3. Emergency assistance
PRIUS_OM_OM47F32E_(EE)
WARNING
■For your safety
● Please drive safely.
The function of this system is to assist you in making the Emergency Call
in case of accidents such as traffic accidents or sudden medical emergen-
cies, and it does not protect the driver or passengers in any way. Please
drive safely and fasten your seatbelts at all times for your safety.
● In case of an emergency, make lives the top priority.
● If you smell anything burning or other unusual smells, leave the vehicle
and evacuate to a safe area immediately.
● Since the system detects shocks, the automatic reporting may not always
occur synchronized with the operation of the airbag system. (If the vehicle
is struck from behind, etc.)
● For safety, do not make the Emergency Call while driving.
Making calls during driving may caus e mishandling of the steering wheel,
which may lead to unexpected accidents.
Stop the vehicle and confirm the safety of your surroundings before mak-
ing the Emergency Call.
● When changing fuses, please use the specified fuses. Using other fuses
may cause ignition or smoke in the circuit and lead to a fire.
● Using the system while there is smoke or an unusual smell may cause a
fire. Stop using the system immediately and consult any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
NOTICE
■ To prevent damage
Do not pour any liquids onto the “SOS” button panel, etc. and do not impact
it.
■ If the “SOS” button panel, speaker or microphone malfunctions during
an Emergency Call or manual maintenance check
It may not be possible to make Emergency Calls, confirm the system status,
or communicate with the ERA-GLONASS/EVAK control center operator. If
any of the above equipment is damaged, please consult any authorized
Toyota retailer, Toyota authorized repairer, or any reliable repairer.

Hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it is a high volt-
age system (about 600 V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

For safety and security
There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the hybrid
battery (traction battery). If the
vent is blocked, charging/dis-
charging of the hybrid battery
(traction battery) may become lim-
ited.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions.

■If a warning light comes on, a warning message is displayed, or the
12-volt battery is disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light ( P. 583) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
7.5 L [2.0 gal., 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
● High voltage parts and cables on hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
■ Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).

For safety and security
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.
● Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
● The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the warning labels attached to the vehicle.
● Never try to open the service plug
access hole located under the right side
of the rear seat. The service plug is
used only when the vehicle is serviced
and is subject to high voltage.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front wheels (2WD models)
or four wheels (AWD models) raised. If the wheels connected to the elec-
tric motor (traction motor) are on the ground when towing, the motor may
continue to generate electricity. This may cause a fire. ( P. 572)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

WARNING
■Hybrid battery (traction battery)
● Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be
aware of these dangers.
● If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
or a qualified service shop. If the hybrid battery is not disposed of properly,
it may cause electric shock that can result in death or serious injury.
