• If electricity needed for EV driv-
ing in EV mode or AUTO EV/HV 
mode is not remaining, the oper-
ation mode will be automatically 
switched to HV mode.
• The operation mode can be 
switched to HV mode at any tim-
ing by operating the switch to 
keep electricity for EV driving 
etc.
* (P.86). Switching to HV 
mode when driving on a highway 
or when driving uphill is recom-
mended in order to conserve bat-
tery power.
When in HV mode, the HV drive mode 
indicator illuminates.
*: The EV driving range may reduce 
even after switching to HV mode.
■Hybrid battery (traction bat-
tery) charge mode (P.87)
Electricity generated in the gasoline 
engine can be charged in the hybrid 
battery (traction battery) by switch-
ing to the hybrid battery (traction 
battery) charge mode when elec-
tricity needed for EV driving is not 
remaining.
*
• The system may not be able to switch to the hybrid battery (trac-
tion battery) charge mode due to 
the state of the plug-in hybrid 
system. (P.88)
• Charging time differs depending 
on the driving state of the vehicle 
when driving in hybrid battery 
(traction battery) charge mode.
When in the hybrid battery (traction bat-
tery) charge mode, the hybrid battery 
charge mode indicator illuminates.
*: When in the hybrid battery (traction 
battery) charge mode, the hybrid bat-
tery can be charged while driving. 
However, the gasoline engine runs to 
charge the battery and fuel consump-
tion becomes higher compared with 
driving in HV mode.
The plug-in hybrid system opera-
tion modes can be switched using 
the switches.
■Switching the plug-in hybrid 
system operation modes
Press the AUTO EV/HV mode 
switch or EV/HV mode selection 
switch to change modes as the fol-
lowing table shows.

be changed even if the AUTO EV/HV  
mode switch or EV/HV mode selection  switch is pressed. (In this case, the warning message is displayed on the  
multi-information display when the  switch is pressed.)
●When electricity needed for EV driving is not remaining (when in EV mode or AUTO EV/HV mode)
●When the traction battery is almost completely charged (hybrid battery  
[traction battery] charge mode)
■When switching from EV mode to  another mode using the switch
●After switching from EV mode to HV  
mode or hybrid battery (traction bat- tery) charge mode and the power  
switch is turned off, the system  returns to EV mode the next time the  
vehicle is started.*
●After switching from EV mode to  
AUTO EV/HV mode and the power  switch is turned off, the system does not return to EV mode the next time  
the vehicle is started.* 
*: If there is not enough charge remain- 
ing in the hybrid battery (traction bat-
tery) to allow EV driving, the system 
switches to HV mode.
■Hybrid battery (traction battery)  charge mode
●The following may occur to protect the system, etc.• Cannot switch to hybrid battery (trac- 
tion battery) charge mode or cannot  cancel it• Gasoline engine does not start or  
stops even after switching to hybrid  battery (traction battery) charge mode
●If a load to the system is large, such as when the power consumption of the air conditioning system is large or  
when the temperature of the engine  coolant is high, it may take longer time than usual to charge using the hybrid  
battery (traction battery) charge  mode, or charging to the hybrid bat-tery (traction battery) may not be per- 
formed.
■When in EV mode 
In EV mode, EV driving (driving  
using only the electric motor)* is  
possible. However, depending on  
the situation, EV driving may be  
canceled and both gasoline engine  
and electric motor are used  
( P.90). Also, if a little electricity is  
remaining in the hybrid battery  
(traction battery), HV mode is auto- 
matically 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

WARNING
■When using the hybrid battery  (traction battery) charge mode 
Observe the following precautions  
when using the hybrid battery (trac- tion battery) charge mode while park-ing. 
Failure to do so may lead to death or  serious health hazard, as the gasoline engine operates when in the hybrid  
battery (traction battery) charge  mode.
●Do not stop the vehicle near flam- 
mable materials.
●Do not use the hybrid battery (trac-
tion battery) charge mode in a  closed area where ventilation is insufficient, such as in a garage or  
area with snow buildup.
Control when driving in

922-1. Plug-in hybrid system
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.
■Refilling fuel 
Plug-in hybrid vehicles can be driven  
using electricity charged from an exter- nal power source. However, as the gas-oline 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.342)
■If the vehicle is not used for a long  time
●The 12-volt battery may discharge. In  
this event, charge the 12-volt battery.  ( P.606) 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.606) and perform  the correction procedure.
●When 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, immediately remove it  from the vehicle.
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).

■Running out of fuel 
When the vehicle has run out of fuel and  
the hybrid system cannot be started,  refuel the vehicle with at least enough gasoline to make the low fuel level warn- 
ing light ( P.575) go off. If there is only  a small amount of fuel, the hybrid sys-tem may not be able to start. (The stan- 
dard amount of fuel is about 8.8 L [2.3  gal., 1.9 Imp.gal.], when the vehicle is on a level surface. This value may vary  
when the vehicle is on a slope. Add  extra fuel when the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-magnetic shielding, and therefore emit  
approximately the same amount of  electromagnetic waves as conven-tional gasoline powered vehicles or  
home electronic appliances.
●Your vehicle may cause sound inter-
ference in some third party-produced  radio parts.
■Effect of magnetic forces 
If objects that generate strong magnetic  
forces, such as large speakers, are  placed inside the luggage compartment or installed nearby, the generated mag- 
netic forces may negatively affect the  hybrid system.
■Hybrid battery (traction battery) (lithium-ion battery) 
The hybrid battery (traction battery) has  a limited service life. 
The hybrid battery (traction battery)  
capacity (the ability to hold a charge)  reduces with time and use in the same way as other rechargeable batteries.  
The extent at which capacity reduces  
changes drastically depending on the  environment (ambient temperature, etc.)  
and usage conditions, such as how the  vehicle is driven and how the hybrid bat-tery (traction battery) is charged. This is  
a natural characteristic of lithium-ion  batteries, and is not a malfunction. Also, even though the EV driving range  
becomes shorter when the hybrid bat- tery (traction battery) capacity reduces, vehicle performance does not signifi- 
cantly become worse. 
In order to reduce the possibility of the  capacity reducing, follow the directions  
listed on P.134, “Capacity reduction of  the hybrid battery (traction battery)”.
■Starting the hybrid system in an extremely cold environment 
When the hybrid battery (traction bat- tery) is extremely cold (below approxi-mately -30°C [-22°F]) under the  
influence of the outside temperature, it  may not be possible to start the hybrid system. In this case, try to start the  
hybrid system again after the tempera- ture of the hybrid battery increases due to the outside temperature increase etc.
■Declaration of conformity 
This model conforms to hydrogen emis- sions according to regulation ECE100 (Battery electric vehicle safety).

WARNING
■High voltage precautions 
The vehicle has high voltage DC and  
AC systems as well as a 12-volt sys- tem. DC and AC high voltage is very dangerous and can cause severe  
burns and electric shock that may  result in death or serious injury. 

982-1. Plug-in hybrid system
There is an air intake vent under  
the rear seat for cooling the DC/DC  
converter. 
Blocking the air intake vent may  
prevent the plug-in hybrid system  
from operating properly. 
When a certain level of impact is  
detected by the impact sensor, the  
emergency shut off system blocks  
off the high voltage current and 
NOTICE
■Notice about fuel
●For plug-in hybrid vehicles, fuel  
may remain in the tank for a long  time and undergo changes in qual-ity depending on the how the vehi- 
cle is used. Refuel at least 20 L (5.3  gal., 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least 20  
L [5.3 gal., 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. If the message is displayed, refuel the vehicle immediately.

NOTICE
■DC/DC converter air intake vent
●Make sure not to block the air  
intake vent with anything, such as a  seat cover, plastic cover, or lug-gage. Blocking the air intake vent  
may prevent the plug-in hybrid sys- tem from operating properly.
●When dust etc. has accumulated in the air intake vent, clean it with a vacuum cleaner to prevent the vent  
from clogging.
●Do not wet or allow foreign sub-
stances to enter the air vent as this  may cause a short circuit and dam-age the DC/DC converter.
●Do not carry large amounts of water such as water cooler bottles in the  
vehicle. If water spills onto the  DC/DC converter, the converter may be damaged. Have the vehicle  
inspected by any authorized Toyota  retailer or Toyota authorized repairer, or any reliable repairer.
●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.536.
●If “Maintenance required for DCDC converter cooling parts See Owner’s Manual” is shown on the  
multi-information display, the air  intake vent and filter may be clogged. Refer to P.536 for informa- 
tion on how to clean the air intake  vent.
Emergency shut off system 

1002-1. Plug-in hybrid system
Shift the shift lever to D when 
stopped at a traffic light, or driving 
in heavy traffic etc. Shift the shift 
lever to P when parking. When 
using the N, there is no positive 
effect on fuel consumption. In the 
N, the gasoline engine operates but 
electricity cannot be generated. 
Also, when using the air condition-
ing system, etc., the hybrid battery 
(traction battery) power is con-
sumed.
Drive your vehicle smoothly. 
Avoid abrupt acceleration and 
deceleration. Gradual accelera-
tion and deceleration will make 
more effective use of the electric 
motor (traction motor) without 
having to use gasoline engine 
power.
Avoid repeated acceleration. 
Repeated acceleration con-
sumes hybrid battery (traction 
battery) power, resulting in poor 
fuel consumption. Battery power 
can be restored by driving with 
the accelerator pedal slightly 
released.
Make sure to operate the brakes 
gently and a timely manner. A greater amount of electrical energy 
can be regenerated when slowing 
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to high fuel and 
electricity consumption. Check traf-
fic reports before leaving and avoid 
delays as much as possible. When 
driving in a traffic jam, gently 
release the brake pedal to allow the 
vehicle to move forward slightly 
while avoiding overuse of the accel-
erator pedal. Doing so can help 
control excessive electricity and 
fuel consumption.
Control and maintain the vehicle 
at a constant speed. Before stop-
ping at a toll booth or similar, 
allow plenty of time to release 
the accelerator and gently apply 
the brakes. A greater amount of 
electrical energy can be regener-
ated when slowing down.
Electricity consumption will 
increase significantly when driv-
ing at high speeds in EV mode or 
AUTO EV/HV mode. If there will 
be a long distance to the next 
external charging point after 
leaving a freeway, it is recom-
mended to drive in HV mode

Plug-in hybrid system
equipped with a Residual Cur- 
rent Circuit-Breaker (RCCB). If it  
is not, have one installed by a  
duly qualified professional. 
 When charging outdoors, make  
sure to connect to a rain-tight  
socket that is certified for outdoor  
use. Checking Residual Current  
Circuit-Breaker (RCCB) opera- 
tion before its use is recom- 
mended. 
 Check whether there are any  
local EV-charging regulations in  
place, and adhere to them.
*: For detailed information, consult an  
electrician.
■The charging environment 
For safe charging, the following  charging equipment and settings are  
recommended.
●Rain-tight socket 
When charging outdoors, connect the  
plug to a rain-tight socket, and ensure 
that the plug remains waterproof while 
the plug is connected.
●Dedicated circuit 
• To reduce the risk of fire, connect only  to an at least 13A branch circuit with an over-current protection. 
• To reduce the risk of electric shock  when working with the plug, connect to a socket that has a Residual Cur- 
rent Circuit-Breaker (RCCB) installed.
●Remote switch 
Allows the electricity from the socket to  
be interrupted by operating a switch, 
thus allowing safe removal and insertion 
of the plug on rainy days.
■When your circuit breaker trips  
during charging 
The upper limit of the charging current  
can be changed in “Vehicle Settings” on  
the multi-information display.

even after changing the upper limit of  the charging current, check if the con-nected power source meets the speci- 
fied charging conditions. ( P.124)*1: Vehicles with 6.6 kW onboard trac- 
tion battery charger only
*2: Restricting the charging current will 
lengthen the charging time.
