hybrid battery (traction battery)
from an external power source
before using the vehicle.
Even if charging the hybrid battery
(traction battery) has not been com-
pleted, the vehicle can be driven. How-
ever, if there is not enough charge
remaining, it is possible that the vehicle
cannot be driven in EV mode or AUTO
EV/HV mode, or the EV driving range
will become shorter.
QRefilling fuel
Plug in Hybrid Electric Vehicles can be
driven using electricity charged from an external power source. However, as the gasoline engine is used depending on
the situation ( P.90) even if in EV mode or AUTO EV/HV mode, and the gasoline engine is provided on board as
a power source for driving in HV mode, it is needed to refueling the vehicle.
Check the fuel amount and refill immedi-
ately when the fuel level becomes low. ( P.298)
QIf the vehicle is not used for a long time
OThe 12-volt battery may discharge. In
this event, charge the 12-volt battery. ( P.546) In order to prevent the hybrid battery
(traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from external power source or start the
hybrid system at least once every 2 or 3 months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after approximately 10 seconds have
passed since the “READY” indicator came on, the power switch can be turned to off without any further
action.) When the 12-volt battery is dis-charged, refer to “If the 12-volt battery
is discharged” ( P.546) and perform the correction procedure.
OWhen the vehicle is left with the AC charging cable connected, the elec-tricity consumption amount of the 12-
volt battery increases due to controls, such as the system checking, operat-ing. When the AC charging cable is
not needed, remove it from the vehi- cle.
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of the
vehicle’s approach. The sound will
stop when the vehicle speed
exceeds approximately 25 km/h (15
mph).
QAcoustic Vehicle Alerting System
In the following cases, the Acoustic
Vehicle Alerting System may be difficult for surrounding people to hear.
OIn very noisy areas
OIn the wind or the rain

2 2-1. Plug-in hybrid system
Plug-in hybrid system
stops the fuel pump to minimize the
risk of electrocution and fuel leak-
age.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the hybrid sys-
tem, contact any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
A message is automatically dis-
played when a malfunction occurs
in the hybrid system or an improper
operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the instruc-
tions.
QIf a warning light comes on, a warn-
ing message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that
case, try to start the system again. If the
“READY” indicator does not come on,
contact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
Primarily using EV mode and
AUTO EV/HV mode when driving in
cities and using HV mode when
driving on highways (or freeways)
can help conserve fuel and electric-
ity. (P.86)
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
fuel and electricity economy.
(P.387)
Eco-friendly driving is possible by
keeping the Hybrid System Indica-
tor within Eco area. (P.175)
