2-1. Plug-in hybrid system
2
Plug-in hybrid system
driving range (P.172) is being dis-
played on the multi-information dis-
play, EV driving (driving using only
the electric motor) may be canceled
and both gasoline engine and elec-
tric motor are used depending on
the situation (EV driving will be
returned to automatically after EV
driving becomes possible again).
EV driving may be canceled auto-
matically in the following circum-
stances
*1
:
● When vehicle speed is more than
approximately 84 mph (135 km/h).
● When power is needed temporar-
ily, for example when the acceler-
ator pedal is depressed firmly or
when accelerating suddenly.
*2
● When the temperature of the
hybrid system is high.
The vehicle has been left in the
sun, driven on a hill, driven at high
speeds, etc.
● When the temperature of the
hybrid system is low.
● When the heater is switched on
when the outside temperature is
below about 14°F (-10°C).
● When the windshield defogger
switch is pressed. (P.398)
● When the system determines that
the gasoline engine needs to be
started.
*1
:The gasoline engine may also
operate in circumstances other
than those listed above, depend-
ing on conditions.
*2
:When driving in AUTO EV/HV
mode. Even in EV mode, the gas-
oline engine may start, depend-
ing on the condition of the hybrid
battery (traction battery).
■ If “Engine Started to Protect
System EV driving unavailable”
is displayed on the multi-infor-
mation display
EV driving may be canceled in order
to protect the hybrid system, etc.
In this case, perform driving with the
gasoline engine until EV driving will
be returned to automatically.
■ Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it
may not stop automatically in the
following conditions
*
:
● During gasoline engine warm-up
● During hybrid battery (traction bat-
tery) charging
● When the temperature of the
hybrid battery (traction battery) is
high or low
● When the windshield defogger
switch is pressed. (P.398)
*
: Depending on the circumstances,
the gasoline engine may also not
stop automatically in situations
other than those above.
■ Sounds and vibrations specific
to a hybrid vehicle
There may be no engine sound or
vibration even though the vehicle is
able to move with the “READY” indi-
cator is illuminated. For safety,
apply the parking brake and make
sure to shift the shift lever to P when
parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion.
● Motor sounds may be heard from
the engine compartment.
● Sounds may be heard from the
hybrid battery (traction battery)
when the hybrid system starts or
stops.
● Relay operating sounds such as a
snap or soft clank will be emitted
from the hybrid battery (traction
battery), behind the rear seats,
when the hybrid system is started
or stopped.
