WARNING
■Pregnant women
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 34)
■ When children are in the vehicle
 P. 6 9
■ Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that
case, the seat belt cannot be used again and must be replaced at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
Obtain medical advice and wear the seat
belt in the proper way. ( P. 34)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.

The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. 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 occu-
pants.

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 devic es 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.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.)
of inflation, placing yourself 250 mm ( 10 in.) 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
250 mm (10 in.) away now, you can change your driving position in sev-
eral 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 250 mm (10 in.) 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-slippery cushion, or raise the
seat if your vehicle has that feature.
• 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 above, while still maintain-
ing control of the foot pedals, steering wheel, and your view of the instru-
ment panel controls.
● The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seat belt should be properly secured using a child restraint sys-
tem. Toyota strongly recommends that all infants and children be placed in
the rear seats of the vehicle and proper ly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( P. 54)

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■ Important points while driving
● Keep the back door closed.
● If you smell exhaust gases in the vehicle even when the back door is
closed, open the side windows and have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi-
cle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.

521-2. Child safety
PRIUS_OM_OM47F32E_(EE)
Insert the mechanical key into the
cylinder and turn to the “OFF”
position.
The “OFF” indicator light turns on
(only when the power switch is in
ON mode).
■ “PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction
in the system. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
● The “OFF” indicator does not illuminate when the airbag manual on-off
switch is set to “OFF”.
● The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.
Deactivating the airbag for the front passenger
WARNING
■ When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In
the event that the rear seat cannot be used, the front seat can be used as
long as the airbag manual on-off system is set to “OFF”.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
■ When a child restraint system is not installed on the front passenger
seat
Ensure that the airbag manual on-off system is set to “ON”.
If it is left off, the airbag will not deploy in the event of an accident, which
may result in serious injury or even death.

771-3. Emergency assistance

PRIUS_OM_OM47F32E_(EE)
For safety and security
WARNING
■When the Emergency Call may not be made
● It may not be possible to make Emergency Calls in any of the following sit-
uations. In such cases, report to emergency services provider (112 system
etc.) by other means such as nearby public phones.
• Even when the vehicle is in the cellular phone service area, it may be
difficult to connect to the ERA-GLONASS/EVAK control center if the
reception is poor or the line is busy. In such cases, even though the sys-
tem attempts to connect to the ERA-GLONASS/EVAK control center,
you may not be able to connect to the ERA-GLONASS/EVAK control
center to make Emergency Calls and contact emergency services.
• When the vehicle is out of the cellular phone service area, the Emer-
gency Calls cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator
lights, microphone, speaker, DCM, antenna, or any wires connecting
the equipment) is malfunctioning, damaged or broken, the Emergency
Call cannot be made.
• During an Emergency Call, the system makes repeated attempts to
connect to the ERA-GLONASS/EVAK control center. However, if it can-
not connect to the ERA-GLONASS/EVAK control center due to poor
radio wave reception, the system may not be able to connect to the cel-
lular network and the call may finish without connecting. The red indica-
tor light will blink for approximately 30 seconds to indicate this
disconnection.
• This device may not function if a shock is applied to it.
● If the 12-volt battery’s voltage decreases or there is a disconnection, the
system may not be able to connect to the ERA-GLONASS/EVAK control
center.
■ When the Emergency Call system is replaced with a new one
The Emergency Call system should be registered. Contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

861-4. Hybrid system
PRIUS_OM_OM47F32E_(EE)
■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).
