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 sys-
tem from operating properly.When a certain level of impact is
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 m ay 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 di splay 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 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.

4006-1. Using the air conditioning system and defogger
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally. This may also reduce fuel
consumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by pressing
the outside/recirculated air mode
switch.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Engine speed and compressor operation controlled to restrict
heating/cooling capacity
• Fan speed restr icted when auto-
matic mode is selected
●To improve air conditioning perfor-
mance, perform the following
operations:
• Turn off Eco drive mode ( P.377)
• Turn off Eco air conditioning mode
●When the driving mode is set to
Eco driving mode, the Eco air con-
ditioning mode will be turned on
automatically. Even in this case,
the Eco air conditioning mode can
be turned off by pressing the Eco
air conditioning mode switch.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from inside and outside the vehicle may
enter into and accumulate in the
air conditioning system. This may
then cause odor
to be emitted
from the vents.
●To reduce potential odors from
occurring:
• It is recommended that the air
conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Make sure that “IGNITION ON”
on the multi-info rmation display
and the “READY” indicator are
both off.
ItemsParts and tools●Keep hands, clothing and tools
away from the moving fan.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, c ause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.463)
■Safety glasses
Wear safety gla sses to prevent
flying or falling material, fluid
spray, etc., from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the ai r cleaner filter
removed may cause excessive
engine wear due to dirt in the air.

5248-2. Steps to take in an emergency
a safe place and, if the fuel level is
low, refuel the vehicle.
• “Hybrid System Stopped”
• “Engine Stopped”
●If “Maintenance required for
DCDC converter cooling parts
See Owner’s Manual” is shown,
the filter may be clogged, the air
intake vent may be blocked, or
there may be a gap in the duct.
Therefore, perform the following
correction procedure.
• If the air intake vent or filter of the DC/DC converter are dirty, per-
form the procedures on P.486 to
clean them.
• If the warning message is shown
when the air intake vent and filter
of the DC/DC converter are not
dirty, have the vehicle inspected
at your Toyota dealer.
●If “12-Volt Battery Charging Sys-
tem Malfunction Stop in a Safe
Place See Owner’s Manual” is
shown
Indicates a malfunction in the vehi-
cle’s charging system. Pull over and
stop the vehicle as soon as it is safe
to do so.
While the message is displayed, the
functions of the air conditioning, etc.
may be partially lim ited in order to
reduce the power consumption of
the 12-volt battery.
■If “Hybrid System Overheated
Output Power Reduced” is
shown
The message may be shown when
driving under severe operating con-
ditions. (For example, when driving
up a long steep hill or driving up a
steep hill in reverse.)
Coping method: P.544
■If “Traction Battery Needs to be
Protected Refrain from the Use
of N Position” is shown
This message may be displayed
when the shift lever is in N. As the hybrid battery (traction bat-
tery) cannot be charged when the
shift lever is in N, shift the shift lever
to P when the vehicle is stopped.
■If “Traction Battery Needs to be
Protected Shift into P to
Restart” is shown
This message is displayed when the
hybrid battery (traction battery)
charge has becom e extremely low
because the shift lever has been left
in N for a certain amount of time.
When operating the vehicle, shift to
P and restart the hybrid system.
■If “Shift to P when Parked” is
shown
Message is displayed when the
driver’s door is opened without turn-
ing the power switch to OFF with the
shift lever in any p osition other than
P.
Shift the shift lever to P.
■If “Shift is in N Release Acceler-
ator Before Shifting” is shown
Message is displayed when the
accelerator pedal has been
depressed and the shift lever is in N.
Release the accelerator pedal and
shift the shift lever to D or R.
■If “Press Brake when Vehicle is
Stopped Hybrid System may
Overheat” is shown
Message is displayed when the
accelerator pedal is depressed to
maintain the vehicl e position when
stopped on a upward slope, etc.
If this continues, the hybrid system
may overheat.
Release the accelerator pedal and
depress the brake pedal.
■If “Auto Power OFF to Conserve
Battery” is shown
Power was turned off due to the
automatic power off function.
Next time when starting the hybrid
system, operate the hybrid system
for approximately 5 minutes to
