PRIUS_OM_OM47F32E_(EE)
For safety and security
■If the SRS airbags deploy (inflate)
● Slight abrasions, burns, bruising etc., may be sustained from SRS airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, and roof side rails,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● The hybrid system will be stopped and fuel supply to the engine will be
stopped. ( P. 85)
● The emergency flashers will turn on automatically. (P. 568)
● Vehicles with “ERA-GLONASS/EVAK”: If any of the following situations
occur, the system is designed to send an emergency call* to the “ERA-
GLONASS/EVAK control center”, notifying them of the vehicle’s location
(without needing to push the “SOS” button) and an agent will attempt to
speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent auto-
matically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( P. 74)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
• The vehicle is involved in a rollover accident.
*: In some cases, the call cannot be made. ( P. 7 7 )
■ SRS airbag deployment conditions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 20 -
30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.

461-1. For safe use
PRIUS_OM_OM47F32E_(EE)
■ SRS airbag deployment conditions (SRS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event of an
impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by an approximately 1500 kg [3300 lb.] vehicle
colliding with the vehicle cabin from a direction perpendicular to the vehicle
orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
● Both SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.
■ Conditions under which the SRS airbags may deploy (inflate), other than
a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a
serious impact occurs to the underside of your vehicle. Some examples are
shown in the illustration.
■ Types of collisions that may not deploy the SRS airbags (SRS front air-
bags)
The SRS front airbags do not generally infl ate if the vehicle is involved in a
side or rear collision, if it rolls over, or if it is involved in a low-speed frontal
collision. But, whenever a collision of any type causes sufficient forward
deceleration of the vehicle, deployment of the SRS front airbags may occur.
● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
● Collision from the side
● Collision from the rear
● Vehicle rollover

For safety and security
■Regenerative braking
● In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in c onjunction with the recharging of the
hybrid battery (traction battery).
• The accelerator pedal is released while driving with the shift position in D
or B.
• The brake pedal is depressed while driv ing with the shift position in D or
B.
● Vehicles with GPF system: While the GPF system (P. 440) is operating to
regenerate the exhaust gas filter, the hybrid battery (traction battery) may
not be recharged.
■ Hybrid System Indicator
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions*:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery (traction battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 16 km (10 miles). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact any authorized Toyota retailer or 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.

■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).

use the display.
■ Pop-up display
Some functions, such as the driving mode select switch and air conditioning
system, are operation-linked and display pop-up screens on the multi-infor-
mation display. If the pop-up screens of these functions are not desired, they
can be turned off in the “Meter Customize” settings. ( P. 156)
WARNING
■To prevent an accident
■ Caution for use while driving
For safety, avoid operating the meter control switch while driving as much
as possible, and do not look continuously at the multi-information display
while driving. Stop the vehicle and operate the meter control switch. Failure
to do so may cause a steering wheel operation error, resulting in an unex-
pected accident.
NOTICE
■ The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
