Opening the fuel tank cap
The fuel tank of your vehicle has a special structure, which requires
a reduction in fuel tank pressure before refueling. After the opener
switch has been pressed, it will take several seconds until the vehi-
cle is ready for refueling.
■Before refueling the vehicle
●Turn the “POWER” switch off and close all the doors and win-
dows.
●Confirm the type of fuel. (oP. 1 8 0 )
■Opening the fuel tank cap
Press the fuel filler door
opener switch.
The screen to the left is dis-
played for a short period. Wait
until “REFUEL READY” is dis-
played, then proceed to the
next step.

■Fuel types
Use unleaded gasoline. (Octane rating 87 [Research Octane Number 91] or
higher)
■If the fuel filler door opener is inoperable
If the fuel filler door opener switch cannot be operated, contact your Toyota
dealer. In the event that urgent refueling is required, follow the procedure
below.
Remove the cap slowly. Take care to prevent fuel from spilling
out, as fuel tank pressure may not have been adequately
reduced.
Fill the fuel tank carefully and slowly. Use caution, as air being
discharged from inside the fuel tank may cause fuel to spray out
from the filler opening during refueling.
Open the fuel filler door using the lever in
the luggage compartment.STEP 1

CAUTION
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel filler door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
●Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the fuel filler neck
●Stop filling the tank after the fuel nozzle automatically clicks off
●Do not top off the fuel tank
■When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

NOTICE
■Refueling
●Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may spill out if you continue to
refuel the vehicle. About 5 minutes after the valve is closed, a message
“CLOSE FUEL LID” will appear on the multi-information display. To refuel
the vehicle again, tighten fuel tank cap and close the fuel filler door, and
then press the fuel filler door opener switch again.
●Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.
■Notice about fuel
For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
●Engine speed and compressor operation controlled to restrict heating/
cooling capacity
●Fan speed restricted when automatic mode is selected
To i m p r o v e a i r c o n d i t i o n i n g p e r f o r m a n c e , p e r f o r m t h e f o l l o w i n g o p e r a t i o n s :
●Adjust the fan speed
●Turn off Eco drive mode (oP. 2 5 1 )
●Customize the air conditioning control of Eco drive mode. (oP. 6 4 7 )
■When outside air temperature is below 32°F (0°C)
The cooling and dehumidification function may not operate even when
is pressed.
■Ve nt i l a t i on a nd a i r c on di t i o ni n g od o rs

●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
●To r e d u c e p o t e n t i a l o d o r s f r o m o c c u r r i n g :
•It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
•The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic
mode.
■Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.

4-2. Maintenance
PRIUS PHV_OM_OM47A11U_(U)
Emission inspection and maintenance (I/M) programs
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system moni-
tors the operation of the emission control system.
■If the malfunction indicator lamp comes on
The OBD system determines that a problem exists somewhere
in the emission control system. Yo u r v e h i c l e m a y n o t p a s s t h e I /
M test and may need to be repaired. Contact your Toyota dealer
to service the vehicle.
■Yo u r v e h i c l e m a y n o t pa s s t h e I / M t e s t i n t h e f o l l o w i n g s i t u a -
tions:
●When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are
erased.
Also, depending on your driving habits, the readiness codes
may not be completely set.
●When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a tempo-
rary malfunction and your vehicle may not pass the I/M test.
■When the malfunction indicator lamp still remains on after
several driving trips
The error code in the OBD system will not be cleared unless the
vehicle is driven 40 or more times.
■If your vehicle does not pass the I/M test
Contact your Toyota dealer to prepare the vehicle for re-testing.
