NOTICE
■Notice about fuel
●For Plug-in Hybrid Electric Vehi-
cles, 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 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 sys-
tem 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.
DC/DC converter air intake
vent
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.504.
●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.504 for informa-
tion on how to clean the air intake vent.
Emergency shut off system

1042-1. Plug-in hybrid system
■When starting off, depress the
accelerator pedal smoothly to
accelerate
As a guide, accelerate up to
approximately 20 km/h (12mph) in
the first 5 seconds.
Electrical and fuel efficiency can be
improved just by using the ECO
Accelerator Guidance displayed on
the multi-information display and
taking care to start off gently.
(P.202)
When the driving mode is set to Eco
drive mode, depressing the accelerator
pedal generates smooth torque that
makes it easier to operate the accelera-
tor gently.
■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 vehi-
cle, such as at a traffic light
The regenerative brake will operate
to convert the kinetic energy of the
vehicle into electrical energy, which
will charge the hybrid battery (trac-
tion battery).
The regeneration status can be
checked from the Hybrid System
Indicator. (P.190)When the brake pedal is depressed
lightly during deceleration, the
regeneration amount increases,
enabling more electrical energy to
be recovered.
If the brake pedal is depressed too
strongly, the recovered amount indica-
tor will reach the maximum level and
the upper limit of the recoverable
energy will be exceeded. Therefore, be
sure to operate the brake pedal early.
■Use the air conditioning sys-
tem appropriately, and also
utilize the heated steering
wheel (if equipped) and seat
heaters
In EV mode, the vehicle is cooled
and heated by electrical energy.
(Except in extremely cold tempera-
tures of approximately -10°C (14°F)
or less.)
Preventing excessive cooling or
heating of the vehicle will reduce
power consumption and improve
electrical efficiency.
The heated steering wheel (if
equipped) and seat heaters are effi-
cient heating device that directly
warm the body using less electric
power.
When used together with the air condi-
tioning system, a low temperature set-
ting can be used to improve electrical
and fuel efficiency.
■Check the tire pressure
If the tire pressure is lower than the
specified value, it will worsen the
electrical and fuel efficiency.
