using only the electric motor)
possible. However, depending
on the situation, EV driving may
be canceled and both gasoline
engine and electric motor are
used (P.82). Also, if a little
electricity is remaining in the
hybrid battery (traction battery),
HV mode is automatically
selected. To drive in EV mode
long, observe the followings.
 Avoid sudden acceleration
and sudden deceleration, and
be sure to drive smoothly. If
you repeatedly accelerate,
the hybrid battery (traction
battery) charge will deplete
quickly. Also, EV driving may
be canceled by rapid acceler-
ation or vehicle speed.
 Restrain your speed as much
as possible. The distance that
can be driven in EV mode will
reduce considerably at high
speeds.

: The EV driving range can be
checked using the multi-informa-
tion display. (P.172)
When in AUTO EV/HV mode
■
Only the electric motor is used
*
for EV driving during normal
driving, but when the accelera-
tor pedal is strongly depressed,
the gasoline engine starts.
(P.82)
Also, when the hybrid battery
(traction battery) level is low, the
mode switches to HV mode

mode.
AUTO EV/HV mode is suitable
for driving conditions when more
power is required, such as for
driving uphill or accelerating
suddenly. However, because
the gasoline engine will start
more easily, it is recommended
to drive in EV mode usually.

tion display. (P.172)
When in HV mode
■
The vehicle can be used in the
same way as a standard hybrid
vehicle.
In HV mode, controls are pri-
marily carried out as follows in
accordance with the driving con-
ditions.
 The gasoline engine stops
when the vehicle is stopped.
 During start off, the electric
motor (traction motor) drives
the vehicle.
 During normal driving, the
gasoline engine and electric
motor (traction motor) are
controlled effectively, and the
vehicle is driven with optimum
fuel efficiency. Also, when
necessary, the electric motor
(traction motor) operates as
an electrical generator to
charge the hybrid battery
(traction battery).
