10 The Prius Prime system has features of both electric and hybrid vehicles. Electricity
received by charging from an external power source can be used to supplement
hybrid energy, and the vehicle can also be driven as an electric vehicle using only
the electric motor. The EV driving range can be extended by using regenerative
braking to store electricity in the traction battery.
ELECTRIC VEHICLE SYSTEM
Charging equipment
The charge cable included with the vehicle is designed to be connected only to
an AC 120V power source.
NOTE: Toyota recommends installing a heavier-duty 15-amp wall receptacle
with GFCI (Ground-Fault Circuit-Interrupter). Refer to the Owner’s Manual for more details.

Hybrid Synergy Drive System
FEATURES & OPERATIONS
The Hybrid Synergy Drive System utilizes a computer-controlled gasoline engine
and electric motor to provide the most efficient combination of power for the
vehicle. To conserve energy, when the brakes are applied the braking force
generates electricity which is then sent to the traction battery. In addition, the
engine shuts off when the vehicle is stopped. The benefits are better fuel economy
and reduced vehicle emissions.
NOTE: Fuel consumption and energy information of the Hybrid System are
shown on the Multi-Information Display.
-Ensure tire pressures are maintained at levels specified in the Owner’s Manual.
-When possible, link trips to reduce engine cold starts.
-Avoid driving at speeds that are higher than necessary, especially on the highway.
-When possible, avoid sudden stops to maximize regenerative braking energy.
-Minimize use of the air conditioning.
