NOTICE
■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 com-
ponents of the fuel system or 
the gasoline engine.
●If the vehicle has not been refu-
eled 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.

■DC/DC converte r air intake 
vent
●Make sure not to block the air 
intake vent with anything, such 
as a seat cover, plastic cover, or 
luggage. Blocking the air intake 
vent may prevent the plug-in 
hybrid system from operating 
properly.
●When dust etc. has accumu-
lated in the air intake vent, clean 
it with a vacuum cleaner to pre-
vent 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 damage the DC/DC con-
verter.
●Do not carry large amounts of 
water such as water cooler bot-
tles in the vehicle. If water spills 
onto the DC/DC converter, the 
converter 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 replace-
ment is recommended. When 
cleaning the filter, refer to 
P.486.
●If “Maintenance required for 
DCDC converter cooling parts 
See Owner’s Manual” is shown 
on the multi-information dis-
play, the air intake vent and fil-
ter may be clogged. Refer to 
P.486 for information on how to 
clean the air intake vent.

detected by the impact sensor, 
the emergency shut off system 
blocks off the high voltage cur-
rent and stops the fuel pump to 
minimize the risk of electrocu-
tion and fuel leakage. 
If the emergency shut off system 
activates, your vehicle will not 
restart. To restart the hybrid sys-
tem, contact your Toyota dealer.
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 
instructions.
■If a warning light comes on, a 
warning message is displayed 
or the 12-volt battery is discon-
nected
The hybrid system  may not start. In 
that case, try to start the system 
again. If the “READY” indicator does 
not come on, contact your Toyota 
dealer.
Primarily using EV mode and 
AUTO EV/HV mode when driv-
ing in cities and using HV mode 
when driving on highways (or 
freeways) can help conserve 
fuel and electricity. ( P.78)
When using Eco drive mode, the 
torque corresponding to the 
accelerator pedal depression 
amount can be generated more 
smoothly than it is in normal 
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be 
minimized, improving fuel and 
electricity economy. ( P.377)
Eco-friendly driving is possible 
by keeping the Hybrid System 
Indicator within Eco area.

Shift the shift lever to D when 
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the 
shift lever to P when parking. 
When using the N, there is no 
positive effect on fuel consump-
tion. In the N, the gasoline 
engine operates but electricity 
cannot be generated. Also, 
when using the air conditioning 
system, etc., the hybrid battery 
(traction battery) power is con-
sumed.
Drive your vehicle smoothly. 
Avoid abrupt acceleration and 
deceleration. Gradual accel-
eration 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 (trac-
tion battery) power, resulting 
in poor fuel consumption. Bat-
tery 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 
deceleration, as well as long 
waits at traffic lights, will lead to 
high fuel and electricity con-
sumption. Check traffic reports 
before leaving and avoid delays 
as much as possible. When driv-
ing in a traffic jam, gently 
release the brake pedal to allow 
the vehicle to move forward 
slightly while avoiding overuse 
of the accelerator pedal. Doing 
so can help control excessive 
electricity and fuel consumption.
Control and maintain the vehi-
cle at a constant speed. 
Before stopping 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 regenerated 
when slowing down.
 Electricity consumption will 
increase significantly when 
driving at high speeds in EV 
mode or AUTO EV/HV mode.

to the next external charging 
point after leaving a freeway,

HV mode while on the free-
way and change to EV mode 
or AUTO EV/HV mode after 
leaving the freeway. (P.78)
 Turn the “A/C” switch off 
when it is not needed. Doing 
so can help reduce excessive 
electricity and fuel consump-
tion.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to 
reduce the burden on the air condi-
tioning system and reduce electric-
ity and fuel consumption as well.
In winter: Avoid excessive and 
unnecessary use o f the heater. 
Usage of the heated steering wheel 
(if equipped) ( P.407) and seat 
heaters ( P.408) are effective.
 Using the Remote Air Condi-
tioning System ( P.405) 
while the AC charging cable is 
connected to the vehicle can 
reduce electricity consump-
tion immediately after starting 
off by operating air condition-
ing mainly using electricity 
from an external power 
source.
 When setting the charging 
schedule, setting the charging 
mode to “Departure” and “Cli-
mate Prep” to on can reduce 
electricity consumption imme-
diately after starting off by 
operating air conditioning  before charging is completed. 
(
P.130)
Make sure to check the tire infla-
tion pressure frequently. If there 
is improper tire inflation pres-
sure in the tires, the EV driving 
range will become shorter, and 
fuel consumption when in HV 
mode will increase.
Also, as snow tires can cause 
large amounts of friction, their 
use on dry roads can lead to 
increased fuel and electricity 
consumption.
Carrying heavy luggage will lead 
to poor fuel economy. Avoid car-
rying unnecessary luggage. 
Installing a large roof rack will 
also cause poor fuel economy.
Since the gasoline engine starts 
up and cuts out automatically, 
warming up is not necessary.

The value displayed on the SOC 
(State of Charge) gauge 
(P.165) is estimated from the 
following information.
 The amount of hybrid battery 
(traction battery) charge cur-
rently remaining
 The electricity consumption 
(the estimated distance that 
EV driving is possible per unit 
of electrical energy) based on 
the recorded value
 Past air conditioning system 
electricity consumption 
amount
The electricity consumption var-
ies depending on how the vehi-
cle is driven. The vehicle  automatically records the elec-
tricity consumption when being 
charged and uses the electricity 
consumption for estimating the 
EV driving range. Therefore, the 
EV driving range displayed 
when the hybrid battery (traction 
battery) is fully charged may dif-
fer from the previous EV driving 
range depending on how the 
vehicle was driven.
The EV driving range may 
change significantly with each 
charging until the electricity con-
sumption based on the recorded 
value is stable (for approxi-
mately the first month or two). 
However, this does not indicate 
a malfunction.
When the air conditioning sys-
tem is turned on, the EV driving 
range (with using the air condi-
tioning system) is estimated 
based on the past air condition-
ing electricity consumption 
amount considering that the 
electricity consumption may 
become higher.
The distance that EV driving is 
possible varies significantly 
depending on how the vehicle is 
driven, road conditions, the 
weather, the outside tempera-
ture, usage conditions of electri-
cal components and the number 
EV driving range
The EV driving range dis-
played on the multi-informa-
tion display shows the 
reference distance that EV 
driving (driving using only 
the electric motor) is possi-
ble, and the actual distance 
that can be driven may dif-
fer from that displayed.
Even if the EV driving range is 
displayed, EV driving may be 
canceled and both gasoline 
engine and electric motor are 
used depending on the situa-
tion. (

Tips for extending the EV 
driving range

of occupants.
The distance that EV driving is 
possible can be extended if the 
following is performed:
■When starting off, depress 
the accelerator pedal 
smoothly to accelerate
As a guide, accelerate up to 
approximately 12mph (20 km/h) 
in the first 5 seconds.
Electrical and fuel efficiency can 
be improved just by using the 
ECO Accelerator Guidance dis-
played on the multi-information 
display and taking care to start 
off gently. ( P.173)
When the driving mode is set to 
Eco drive mode, depressing the 
accelerator pedal generates 
smooth torque that  makes it easier 
to operate the accelerator gently.
At the same time, the air condition-
ing control is switched to eco air 
conditioning mode ( P.397) to 
reduce the strength of the air condi-
tioning operation.
■Maintain sufficient vehicle-
to-vehicle distance and do 
not accelerate or decelerate 
unnecessarily
Try to maintain a fixed speed 
while driving. Driving at a short 
vehicle-to-vehicle distance will 
result in repeating wasteful 
acceleration and deceleration, 
which will worsen the electrical 
and fuel efficiency.
■Release the accelerator 
pedal early before stopping 
the vehicle, such as at a 
traffic light
The regenerative brake will 
operate to convert the kinetic 
energy of the vehicle into electri-
cal energy, which will charge the 
hybrid battery (traction battery).
The regeneration status can be 
checked from the Hybrid Sys-
tem Indicator. ( P.167)
When the brake pedal is 
depressed lightly during decel-
eration, the regeneration 
amount increases, enabling 
more electrical energy to be 
recovered.
If the brake pedal is depressed too 
strongly, the recovered amount 
indicator will reac h the maximum 
level and the upper limit of the 
recoverable energy will be 
exceeded. Theref ore, be sure to 
operate the brak e pedal early.
■Use the air conditioning 
system appropriately, and 
also utilize the heated steer-
ing wheel (if equipped) and 
seat heaters
In EV mode, the vehicle is 
cooled and heated by electrical 
energy. (Except in extremely 
cold temperatures of approxi-
mately 14°F (-10°C) or less.)
Preventing excessive cooling or 
heating of the vehicle will reduce 
power consumption and 
improve electrical efficiency.

When eco air conditioning mode 
is used, the air conditioning con-
trol is switched automatically to 
a lower setting. (P.397)
The heated steering wheel (if 
equipped) and seat heaters are 
efficient heating device that 
directly warm the body using 
less electric power.
When used togethe r with the air 
conditioning system, a low tem-
perature setting can be used to 
improve electrical and fuel effi-
ciency.
■Check the tire pressure
If the tire pressure is lower than 
the specified value, it will 
worsen the electrical and fuel 
efficiency.
A pressure level 7  psi (50 kPa, 0.5 
kgf/cm
2 or bar) lower than the spec-
ified value will cause a worsening of 
several percentage points.
■When driving on highways, 
use the EV/HV mode selec-
tion switch to drive in HV 
mode
The power consumption will 
increase significantly if the vehi-
cle is driven in EV mode on 
highways.
■Do not load unnecessary 
objects in the vehicle
Driving with objects weighing 
220 lb. (100 kg) in the vehicle 
will worsen the electrical and 
fuel efficiency by approximately 
3%. Air resistance also greatly 
affects electrical and fuel effi-
ciency. Remove any exterior 
accessories such as a roof lug-
gage carrier when they are not 
being used.
The running resistance of snow 
tires is high and they will worsen 
electrical and fuel efficiency. 
Replace them with standard 
tires as soon as they are no lon-
ger needed.
■Know your vehicle’s electri-
cal and fuel efficiency
If you know your vehicle’s daily 
electrical and fuel efficiency, you 
will understand the benefits of 
Eco drive.
Use the Power Consump-
tion/Fuel Economy, ECO Accel-
erator Guidance/“Eco Score” 
and other data displayed on the 
multi-information display.
The following indicate that 
charging has been carried out
