Plug-in hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it contains a high
voltage system (about 600V at maximum) as well as parts that
become extremely hot when the hybrid system is operating.
Obey the caution labels attached to the vehicle.

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 vehicle driving tips
XUsing EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV mode
when driving on highways (or freeways) can help conserve fuel and
electricity. (P. 88)
XUsing EV City mode
When using EV City mode, the motor output is limited and the oper-
ation of the gasoline engine can be minimized. Therefore, the vehi-
cle can be driven with only electric motor (traction motor) in city
areas, etc. (P. 88)
XUsing Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improving
fuel and electricity economy. (P. 418)
XUse of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System Indi-
cator within Eco area. (P. 226)
XShift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air conditioning system, etc., the hybrid
battery (traction battery) power is consumed.
For economical and ecological driving, pay attention to the fol-
lowing points:

1072-1. Plug-in hybrid system

Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
XAir conditioning
OTurn the “A/C” switch ( ) off when it is not needed. Doing
so can help reduce excessive electricity and fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 539)
OUsing the Remote Air Conditioning System (P. 535) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
OWhen setting the charging schedule, selecting the start time set-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immediately after starting off by operating air
conditioning before charging is completed. (if equipped)
(P. 166)
XChecking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.

EV driving range
The value displayed on the multi-information display etc. (P. 215,
231, 238, 255) is estimated from the following information.
OThe amount of hybrid battery (traction battery) charge currently
remaining
OThe electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
OPast air conditioning system electricity consumption amount
The electricity consumption varies depending on how the vehicle is
driven. The vehicle automatically records the electricity consumption
when being charged and uses the electricity consumption for estimat-
ing the EV driving range. Therefore, the EV driving range displayed
when the hybrid battery (traction battery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change significantly with each charging
until the electricity consumption based on the recorded value is stable
(for approximately the first month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning system) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumption may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine and electric motor are used depend-
ing on the situation. (P. 9 4 )

The distance that can be driven in EV mode varies significantly
depending on how the vehicle is driven, road conditions, the weather,
the outside temperature, usage conditions of electrical components
and the number of occupants.
The distance that can be driven in EV mode can be extended if the fol-
lowing is performed:
OMaintain a safe distance from the vehicle in front and avoid unnec-
essary acceleration and deceleration
OAccelerate and decelerate the vehicle as smoothly as possible
ODrive at moderate speeds as much as possible and maintain a con-
stant speed
O
Set the air conditioning to a moderate temperature and turn the “A/C”
switch ( ) off when it is not needed
OUse tires of the specified size and maintain the specified tire pres-
sure
OUse the EV/HV mode selection switch to drive in HV mode when
driving on a highway
Electricity consumption will increase substantially when driving on a
highway in EV mode.
ODo not add unnecessary weight to the vehicle
The following indicate that charging has been carried out properly.
OThe charging indicator turns off
OThe Hybrid battery (traction battery) status indicators illuminate for
approximately 15 seconds. (P. 1 1 3 )
O“Charging Complete” is displayed on the multi-information display
when starting off (P. 149)
Regardless of the type of power source or whether the charging
schedule function is used, charging is completed if the above can be
confirmed.
