WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic el ectrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
● If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.
● Do not bring burning or high-temperature items close to the electrolyte.
The electrolyte may ignite and cause a fire.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. ( P. 652)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

◆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.

Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47F38E_(EE)
Before charging, always check the following items.
●The parking brake is applied. (P. 336)
●The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interior lights etc. are switched off.
If these light switches are turned ON, then these features will consume
electricity, and charging time will increase.
●The power switch is off. (P. 323)
Before charging, make sure that each part of the charging cable is in
good condition. (P. 126)
■Safety functions
●The hybrid system will not start while the charging cable is attached to the
vehicle, even if the power switch is operated.
●If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving will not be possi-
ble.
●When the charging cable is connected to the vehicle, the shift position can-
not be changed from P to another position.
■During charging
The followings occur, however, it does not indicate a malfunction.
●The charging starting time may differ depending on the state of the vehicle.
●During charging, the sound of the fan may be heard from the onboard trac-
tion battery charger cooling air intake vents. (P. 154)
●During and after charging, the rear seat and its surrounding area in which
the onboard traction battery charger is installed may get warm.
Confirm the following before charging

Rear seats
Park the vehicle in a safe place.
Apply the parking brake firmly (P. 336) and shift the shift position to P.
( P. 330)
Adjust the position of the front seat and the angle of the seatback.
(P. 290)
Depending on the position of the front seat, if the seatback is folded back-
ward, it may interfere with the operation of the rear seat.
Lower the head restraint of the rear seat. (P. 294)
Stow the armrest of the rear seat if it is pulled out. (P. 563)
This step is not necessary when operating the left side seat only.
Pull the seatback lock release
lever and fold the seatback down.
To avoid trapping the seat belt
between the seat and the inside of
the vehicle, pass the seat belt
inside the seat belt guide and then
return the seatback securely to
the locked position.
The seatbacks can be folded down.
