For safety and security
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag
sensor assembly (ECU) controls airbag deployment based on infor-
mation obtained from the sensors etc. shown in the system compo-
nents diagram above. This information includes crash severity and
occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-toxic gas to help restrain
the motion of the occupants.
WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts
properly.
The SRS airbags are supplemental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause
death or serious injury especially if the driver is very close to the airbag.
The National Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm)
of inflation, placing yourself 10 in. (250 mm) from your driver airbag pro-
vides you with a clear margin of safety. This distance is measured from
the center of the steering wheel to your breastbone. If you sit less than 10
in. (250 mm) away now, you can change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the ped-
als comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in.
(250 mm) distance, even with the driver seat all the way forward, simply
by reclining the back of the seat somewhat. If reclining the back of your
seat makes it hard to see the road, raise yourself by using a firm, non-

• If your steering wheel is adjustable, tilt it downward. This points the air-
bag toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while
still maintaining control of the foot pedals, steering wheel, and your view
of the instrument panel controls.

WARNING
■SRS airbag precautions
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●Do not allow the front seat occupants to
hold items on their knees.
●Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.

681-2. Child safety
PRIUS PRIME_OM_OM47D71U_(U)
◆Removing a child restraint system installed with a seat belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may
spring up due to the rebound of
the seat cushion. Release the
buckle while holding down the
child restraint system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.

801-3. Emergency assistance
PRIUS PRIME_OM_OM47D71U_(U)■
Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GPS data to the already
included warranty-based Toyota roadside service.
Subscribers can press the “SOS” button to reach a Safety Connect
response-center agent, who can help with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Roadside Assistance services and their limitations, please see the
Safety Connect Terms and Conditions, which are available at
Toyota.com in the United States, Toyotapr.com in Puerto Rico and
Toyota.ca in Canada.
Important! Read this information before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wire-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
●ANSI (American National Standards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scientific literature. Over 120 scientists, engi-
neers, and physicians from universities, and government health
agencies and industries reviewed the available body of research to
develop the ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

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.
●Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic electrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
●If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.
●Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.
●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 raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (P. 667)
●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.

locked, carry an electronic key
and press the charging connec-
tor lock switch.
The charging connector is
unlocked by the smart lid & con-
nector locking system.
Carrying an electronic key and moving near the charging inlet will cause
the charging inlet light to illuminate.
Pull the charging connector
towards you while pressing the
latch release button.
If the latch release button is
pressed during charging (while the
charging indicator is on), charging
will be interrupted.
Attach the charging connector
cap.
Attach the charging inlet cap
and close the charging port lid.

2-2. Charging
■When removing the charging connector
■Push lifter (vehicles with smart lid & connector locking system) Press the latch release button, check that
the lever raises up, and then pull the
charging connector towards you.
Vehicles with smart lid & connector lock-
ing system: If the lever does not raise up
even after the latch release button is
pressed, the charging connector is
locked. If this occurs, carry an electronic
key and press the charging connector
lock switch to unlock the charging con-
nector.
When the charging port lid is open, make
sure not to touch the push lifter. If it is
touched accidentally, the charging port lid
or connector lock may operate.
If they are accidentally operated, carry an
electronic key or unlock the doors, and
then press the charging connector lock
switch to unlock.
