2-1. Plug-in hybrid system
WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r 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 electrolyte) from the hy brid 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 bat tery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction ba ttery) is dam-
aged, the internal construction of the battery will prevent a l arge amount of
electrolyte from leaking out. However, any electrolyte that doe s 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-tem perature 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. Th is may
cause a fire. ( P. 655)
● 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 accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on 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 a t
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leav ing and avoid delays as much a s
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to mov e 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 re lease
the accelerator and gently apply the brakes. A greater amount o f
electrical energy can be regenerated when slowing down.
● Electricity consumption will in crease significantly when drivin g 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 rec om-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

2-2. Charging
Before charging, always check the following items.
● The parking brake is applied. ( P. 349)
● The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interi or 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. 3 3 6 )
Before charging, make sure that each part of the charging cable is in
good condition. ( P. 120)
■Safety functions
●The hybrid system will not start while the charging cable is at tached 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 wi ll 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 malfuncti on.
● 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 cha rging
equipment cooling air intake vents. ( P. 145)
● During and after charging, the rear seat and its surrounding ar ea in which
the charging equipment is installed may get warm.
Confirm the following before charging
Inspecting the charging cable
