Plug-in hybrid system
The plug-in hybrid system operates in the following modes.
The multi-information display can be used to check which mode the plug-in
hybrid system is currently being driven in. (→P. 205)
EV mode
When a sufficient amount of electricity is remaining after
charging
*1, EV driving is performed using electricity stored in the
hybrid battery (traction battery).
*2
When in EV mode, the EV drive mode indicator illuminates.
*1: The amount of remaining charge can be checked on the multi-informa- tion display etc. ( →P. 216)
*2: Depending on the situation, EV driving may be canceled and both gaso-
line engine and electric motor are used. ( →P. 87)

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released while driving with the shift position in D or
B.
● The brake pedal is depressed while driving with the shift position in D or \
B.
■ EV driving range
●The EV driving range is displayed on the multi-information display etc.
(→P. 199, 215, 222, 239)
● The EV driving range changes in accordance with the charge status of the
hybrid battery (traction battery), the speed of the vehicle, etc.
● Even if there is enough charge remaining in the hybrid battery (traction bat-
tery), EV driving may be canceled and both gasoline engine and electric
motor are used depending on the situation. ( →P. 87)
■ After EV mode has switched to HV mo de due to low hybrid battery (trac-
tion battery) charge
If the hybrid battery (traction battery) is regenerated by driving continuously
down a long slope, the EV driving range etc. will be displayed on the multi-
information display and EV mode will be automatically switched to.
If EV mode is not switched to even though EV driving range is being dis-
played, EV mode can be switched to by pressing the EV/HV mode selection
switch.
■ Refilling fuel
Plug-in hybrid vehicles can be driven using electricity charged from an exter-
nal power source. However, as the gasoline engine is used depending on the
situation even if in EV 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 immediately when the fuel level becomes
low. ( →P. 356)

■Gasoline engine operatio n in EV/EV auto mode
Even if there is a sufficient amount of electricity remaining in the hybrid bat-
tery (traction battery) and EV driving range ( →P. 199, 215, 222, 239) is being
displayed on the multi-information display etc., EV driving (driving using only
the electric motor) may be canceled and both gasoline engine and electric
motor are used depending on the situat ion (EV driving will be returned to
automatically after EV driving becomes possible again).
EV driving may be canceled automatically in the following circumstances:
● When vehicle speed is more than approximately 84 mph (135 km/h).
● When power is needed temporarily, for example when the accelerator pedal
is depressed firmly or when accelerating suddenly.
*
●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. 491, 501)
● When the system determines that the gasoline engine needs to be started.\
The gasoline engine may also operate in circumstances other than those
listed above, depending on conditions.
*: When traveling in the EV auto mode only
■ Conditions in which the gasoline 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 battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the windshield defogger switch is pressed. ( →P. 491, 501)
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.

Plug-in hybrid system
There are air intake vents on both
sides of the rear seatback for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vents
become blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading to a reduction in
hybrid battery (traction battery)
output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leak-
age. If the emergency shut off syst em activates, your vehicle will not
restart. To restart the hybrid system, contact your Toyota dealer.
A message is automatically displa yed 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
instructions.

NOTICE
■Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● A filter is installed to the air intake vent. When the filter remains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 562.
■ Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-month period), as this
may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.

EV driving range
The value displayed on the multi-information display etc. (→P. 199,
215, 222, 239) is estimated from the following information.
● The amount of hybrid battery (traction battery) charge currently
remaining
● The electricity consumption (the estimated distance that can be
driven in EV mode per unit of electrical energy) based on the
recorded value
● Past air conditioning system electricity consumption amount
The electricity consum ption varies depending on how the vehicle is
driven. The vehicle automatically re cords the electricity consumption
when being charged and uses the el ectricity consumption for estimat-
ing the EV driving range. Therefor e, the EV driving range displayed
when the hybrid battery (traction ba ttery) is fully charged may differ
from the previous EV driving range depending on how the vehicle was
driven.
The EV driving range may change si gnificantly with each charging
until the electricity consumption based on the recorded value is stable
(for approximately the fi rst month or two). However, this does not indi-
cate a malfunction.
When the air conditioning system is turned on, the EV driving range
(with using the air conditioning syst em) is estimated based on the past
air conditioning electricity consumption amount considering that the
electricity consumpt ion may become higher.
The EV driving range displayed on the multi-information display
etc. shows the reference distance that EV driving (driving using
only the electric motor) is possible, and the actual distance that
can be driven may differ from that displayed.
Even if the EV driving range is displayed, EV driving may be can-
celed and both gasoline engine and electric motor are used depend-
ing on the situation. ( →P. 8 7 )
