■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. 717) 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. 162, “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.

Plug-in hybrid vehicle driving tips
◆Using 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. 98)
◆Using 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. 98)
◆Using 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. 468)
◆Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System Indi-
cator within Eco area. (P. 236)
◆Shift 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:

1162-1. Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual acceleration and deceleration will make
more effective use of the electric motor (traction motor) without
having to use gasoline engine power.
●Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (traction battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leaving and avoid delays as much as
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to move forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exces-
sive electricity and fuel consumption.
◆Highway driving
●Control and maintain the vehicle at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be regenerated when slowing down.
●Electricity consumption will increase significantly when driving at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is recom-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

■Charging time may increase
In the following situations, charging time may become longer than normal:
●In very hot or very cold temperatures.
●The vehicle is consuming a lot of electricity, for example, when the head
light switch is on etc.
●There is a power outage during charging.
●There is an interruption in the electrical supply.
●There is a drop in the voltage of external power source.
●The charge in the 12-volt battery is low, for example due to the vehicle being
left unused for a long period of time.
●The maximum charging current is set to 8A through the “Vehicle Settings”
settings. (P. 150)
●When the “Traction Battery Heater” operates.
●When the “Traction Battery Cooler” is operated before charging. (if
equipped) (P. 155)
●When the plug generates heat due to a loose socket connection etc.
■Using a DC Charger
DC Chargers cannot be used with this vehicle.
This vehicle is equipped with several functions that are linked with
charging.
■“Traction Battery Heater”
When the outside temperature is low and the charging cable is con-
nected to the vehicle, this function automatically warms the hybrid
battery (traction battery) until it reaches or exceeds a certain tem-
perature.
●When the charging cable is removed from the vehicle or remains
connected to the vehicle for approximately 3 days, the system
automatically stops.
●When the charging schedule is used (P. 176), this function will
operate according to the charging schedule.
