451-1. For safe use

Prius Plug-in Hybrid_OM_OM47D72E_(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. 109)
● The emergency flashers will turn on automatically. (P. 704)
■ 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.
■ 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.

◆“Fuel Consumption Record”
When the unit is set to “km/h”
The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 km (0.6 mile) or 5 km
(3.1 miles) of driving.
When the unit is set to “MPH” (if equipped)
The transitions of the average fuel consumption after the hybrid
system starts can be checked in units of 1 mile (1.6 km) or 5 miles
(8 km) of driving.
■How to read the screen
The “ 1 km” display is shown as an example. However, the
basic method for how to read the screen is the same for each fuel
consumption history screen.

When the unit is set to “km/h”:
When the recorded unit is
exceeded (every 1 km [0.6 mile]
or 5 km [3.1 miles]) the currently
displayed history moves
towards the left side and the old-
est record is deleted.
When the unit is set to “MPH” (if equipped):
When the recorded unit is exceeded (every 1 mile [1.6 km] or 5 miles
[8 km] the currently displayed history moves towards the left side and
the oldest record is deleted.

Driving
Opening the fuel tank cap
●Turn the power switch off and ensure that all the doors and win-
dows are closed.
●Confirm the type of fuel.
■Fuel types
P. 780
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle

5585-5. Using the driving support systems
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
GPF (Gasoline Particulate Filter) system
■ If “Exhaust Filter Full See Owner’s Manual” is shown on the multi-infor-
mation display
● The message may be displayed while high load driving with particulate mat-
ter accumulating.
● Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to drive the vehicle
unless the malfunction indicator lamp comes on.
● Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low speeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of particulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as when driving on
highways and freeways.
■ 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 certain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable 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
■ To prevent the GPF system from not operating properly
● Do not use fuel other than the specified type
● Do not modify the exhaust pipes

6257-1. Maintenance and care

Maintenance and care
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also
check the belts periodically for excessive wear, fraying or cuts.
■Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid bat-
tery (traction battery) and results in poor electricity and fuel consumption.
Clean the air intake vents and filters periodically.
●If continuing to drive the vehicle with “Maintenance required for Traction bat-
tery cooling parts See owner’s manual” shown on the multi-information dis-
play, the hybrid battery (traction battery) may overheat, leading to
decreasing in distance that can be driven using the electric motor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning
message is shown, clean the air intake vents and filters immediately.
●Improper handling may result in damage to the grille or filters. If you have
any concerns about cleaning the filters, contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
●If the warning message on the multi-information display does not disappear
after cleaning the filters, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
●Timing of cleaning filters differs depending on the use environment of the
vehicle.

When trouble arises
If the hybrid system will not start
One of the following may be the cause of the problem:
● The charging cable may be attached to the vehicle. (P. 165)
● The electronic key may not be functioning properly.* (P. 751)
● There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle. ( P. 1 1 0 )
● There may be a malfunction in the immobilizer system.* (P. 7 4 )
● There may be a malfunction in the shift control system.*
( P. 376, 729)
● The hybrid system may be malfunctioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. How-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. ( P. 750)
● There is a possibility that the temperature of the hybrid battery
(traction battery) is extremely low (approximately below -30 C
[-22 F]). (P. 110, 375)
*: It may not be possible to shift the shift position other than P.
One of the following may be the cause of the problem:
● The 12-volt battery may be discharged. (P. 755)
● The 12-volt battery terminal connections may be loose or corroded.
( P. 644)
Reasons for the hybrid system not starting vary depending on
the situation. Check the following and perform the appropriate
procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. ( P. 373)
The interior lights and headlights are dim, or the horn does not
sound or sounds at a low volume.
