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.

Power (ignition) switch
Check that the parking brake is set.
Firmly depress the brake pedal.
and a message will be dis-
played on the multi-information dis-
play.
When the shift position is N, the
hybrid system cannot start. Shift
the shift position to P when starting
the hybrid system. (P. 254)
Press the power switch shortly
and firmly.
When operating the power switch,
one short, firm press is enough. It
is not necessary to press and hold
the switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake pedal until the “READY” indicator is illumi-
nated.
The hybrid system can be started from any power switch mode.
Check that the “READY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a solid light and
the buzzer sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if the engine
is stopped. (The gasoline engine starts or stops automatically in accor-
dance with the state of the vehicle.)
Performing the following operations when carrying the elec-
tronic key on your person starts the hybrid system or changes
power switch modes.

mode (the hybrid system is not operating) for more than an hour with the shift
position in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent the 12-volt battery discharge. Do not leave the

NOTICE
■To prevent 12-volt battery discharge
● Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
● If “Accessory”, “Ignition ON” or mileage display (P. 121) is displayed on
the main display while the hybrid system is not operating, the power switch
is not off. Exit the vehicle after turning the power switch off.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.
■ Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.

2784-4. Refueling
PRIUS_OM_OM47F32E_(EE)
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any stat ic electricity. It is important to
discharge static electricity before re fueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to pr event fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically clicks off.
● Do not top off the fuel tank.

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become el ectrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Make sure that the “Accessory”, “Ignition ON” or mileage display (P. 118,
120) on the main display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan.
● Be careful not to touch the engine, power control unit, radiator, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
● Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately. If you still experience discom-
fort, consult a doctor.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. ( P. 520)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
