1002-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
QIf 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 To y o t a
retailer or Toyota authorized repairer, or any reliable repairer.
QRunning 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. 660) 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.)
QElectromagnetic waves
OHigh 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.
OYour vehicle may cause sound interference in some third party-produced
radio parts.
QEffect 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.
QHybrid 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)”.
QStarting 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.

Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
This product must be grounded. In case of malfunction or break down,
grounding provides a path of least resistance for electric curr ent to
reduce the risk of electric shock. This product is equipped wit h a
grounding conductor and a grounding plug. The grounding plug mu st
be plugged into an appropriate socket that is properly installe d and
grounded in accordance with all local codes and ordinances.
The CCID (Charging Circuit Interrupting Device) has the followi ng
safety features.
QElectrical leakage detection function
If an electrical leakage is detected during charging, the power
source will be automatically interrupted, thus preventing fires or
electrical shocks caused by electrical leakage.
If the power source is interrupted, the error warning indicator flashes.
If the power source is interrupted: P. 120
QAutomatic check function
This is an automatic system check that is run before charging
begins to check for problems in the operation of the electrical leak-
age detection function.
If a malfunction is found in the electrical leakage detection f unction as a
result of the check, the error warning indicator flashes to inf orm the
user. ( P. 120)
QTemperature detection function
A temperature detection function is equipped to the plug. While
charging, if heat is generated due to looseness on the socket s ide
etc., this function suppresses heat by controlling the charging cur-
rent.
Grounding (Mode 2 charging cable)
WARNING
Q Grounding precautions
O Improper connection of the grounding conductor increases the risk of elec-
tric shock. Check with a qualified electrician or serviceman if you are in
doubt as to whether the product is properly grounded.
O Do not modify the grounding plug provided with the product. If it does not
fit the socket, have a proper socket installed by a qualified e lectrician.
