For safety and security
QIf the SRS airbags deploy (inflate)
O Slight abrasions, burns, bruising etc., may be sustained from SRS airbags,
due to the extremely high speed depl oyment (inflation) by hot gases.
O A loud noise and white powder will be emitted.
O 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, a nd roof side rails,
may be hot for several minutes. The airbag itself may also be h ot.
O The windshield may crack.
O The hybrid system will be stopped and fuel supply to the engine will be
stopped. ( P. 99)
O The emergency flashers will turn on automatically. (P. 646)
Q SRS airbag deployment conditions (SRS front airbags)
O 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 app roximately 20 -
30 km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or
deform).
However, this threshold veloci ty 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
O Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
Q SRS airbag deployment conditions (SRS side and curtain shield airbags)
O 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 mp h]).
O Both SRS curtain shield airbags may also deploy in the event of a severe
frontal collision.

5085-5. Using the driving support systems
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
GPF (Gasoline Par ticulate Filter) system
QIf “Exhaust Filter Full See Owner’s Manual” is shown on the multi-infor-
mation display
O The message may be displayed while high load driving with particulate mat-
ter accumulating.
O Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to driv e the vehicle
unless the malfunction indicator lamp comes on.
O Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low s peeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of par ticulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as w hen driving on
highways and freeways.
Q If the malfunction indicator lamp comes on or “Exhaust Filter Full Visit
Your Dealer” is shown on the multi-information display
The amount of accumulated particulate matter has exceeded a cer tain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reli able repairer immediately.
The GPF system collects particulate matter in the exhaust gas
by using an exhaust gas filter.
The system will operate to regenerate the filter automatically,
depending on the vehicle conditions.
NOTICE
Q To prevent the GPF system from not operating properly
O Do not use fuel other than the specified type
O Do not modify the exhaust pipes

Prius Plug-in Hybrid_OM_OM47E75E_(EE)
WARNING
QWater in the vehicle
O Do not splash or spill liquid in the vehicle, such as on the floor, in the
hybrid battery (traction battery) air intake vent, and in the l uggage com-
partment.
Doing so may cause the hybrid battery (traction battery), elect rical compo-
nents, etc. to malfunction or catch fire.
O Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 40)
An electrical malfunction may cause the airbags to deploy or no t function
properly, resulting in death or serious injury.
O Vehicles with wireless charger:
Do not let the wireless charger ( P. 557) get wet. Failure to do so may
cause the charger to become hot and cause burns or could cause electric
shock resulting in death or serious injury.
Q Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel m ay reflect
off the windshield, obstructing the driver’s view and leading t o an accident,
resulting in death or serious injury.
NOTICE
Q Cleaning detergents
O Do not use the following types of detergent, as they may discolor the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasol ine,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco-
hol
O Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
Q Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deteri oration of
leather surfaces:
O Remove any dust or dirt from leather surfaces immediately.
O Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
O Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
