1002-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47F38E_(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 that 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. 662) 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 the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
●Your vehicle may cause sound interference in some third party-produced
radio parts.
■Effect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are
placed inside the luggage compartment or installed nearby, the generated
magnetic forces may negatively affect the hybrid system.
■Hybrid battery (traction battery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV mode decreases
when the hybrid battery (traction battery) capacity reduces, vehicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the directions
listed on P. 152, “Capacity reduction of the hybrid battery (traction battery)”.
■Starting the hybrid system in an extremely cold environment
When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -30C [-22F]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

1782-2. Charging
Prius Plug-in Hybrid_OM_OM47F38E_(EE)
Solar charging system
This system generates solar power with the solar panel equipped to
the roof of the vehicle (solar roof).
●The hybrid battery (traction battery) is charged
* while parking.
After the solar power is stored in the solar battery, it is transferred
all at once to the hybrid battery (traction battery) to reduce the sys-
tem electrical consumption and charge the battery efficiently.
●The electrical consumption of the hybrid battery (traction battery) is
reduced during driving.
The electrical consumption of the hybrid battery (traction battery) is
suppressed increasing EV driving distance and fuel economy by
supplementing power consumption for the auxiliary systems using
solar power.
*: The maximum charge amount of the solar charging system is approxi-
mately 90% of the fully charged capacity for the charging from an external
power source.
: If equipped
A system that provides power to the hybrid battery (traction bat-
tery) and auxiliary systems by performing solar charging via the
large solar panel (solar roof) equipped on the vehicle roof.
Even when a parking lot does not have charging equipment and in
the event of a disaster, it is possible to charge
* the hybrid battery
(traction battery) without any special operations as long as sunlight
is available.
*: The charging amount via the solar charging system differs depending on
conditions, such as season and weather. Also, there is a limit on the
amount of charging possible per day. It requires at least approximately 10
days to charge to the maximum possible charging amount via the solar
charging system.

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. 724
■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:

WARNING
■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 door, touch an
unpainted metal surface to discharge any stat ic electricity. It is important to
discharge static electricity before re fueling 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 pr event 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.
NOTICE
■Refueling
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.
