■Running out of fuel
When the vehicle has run out of fuel and
the hybrid system c annot 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.], w hen 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 (tr action 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 a nd 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 batter y) capacity reduces, vehicle performance does not signifi -
cantly become worse.
In order to reduce th e 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 c old (below approxi- mately -30°C [-22°F]) under the
influence of the outsi de 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 hy brid battery increases due to the outside temperature increase etc.
■Declaration of conformity
This model conform s 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.

2-2. Charging
Plug-in hybrid system
■Charging from an external
power source ( →P.135)
This is a charging method used
when charging from an AC socket
(220 V - 240 V) with the AC
charging cable equipped to the
vehicle or charging at a public
charging station.
The charging start time (or departure
time) and day can be set to carry out
charging using the charging schedule
at the desired date and time. ( →P.144)
■Using the hybrid battery (trac-
tion battery) charge mode
( →P.87)
The plug-in hybrid system can be
switched to hybrid battery (traction
battery) charge mode to charge the
hybrid battery (traction battery)
using electricity generated by gaso-
line engine operation.
The maximum charge amount in the
hybrid battery (traction battery) charge
mode is approximately 80% of the fully
charged capacity for the charging from
an external power source.
The time required to charge the
hybrid battery (traction battery) dif -
fers according to t he charging volt-
age and charging current.

each part of the AC charging cable
is in good condition. ( →P.117)
■During charging
●The charging starting time may differ
depending on the state of the vehicle,
but this does not indicate a malfunc - tion.
●Cooling fan sounds may be heard from near the rear seat. ( →P.98)
●During charging, sounds may be heard from near the hybrid battery
(traction battery) in accordance with
the operation of the air conditioning system or “Battery Cooler” ( →P.129).
●During and after charging, the rear seat and its surrounding area in which
the onboard traction battery charger is
installed may get warm.
●The surface of the CCID (Charging
Circuit Interrupting Device) may become hot, but this does not indicate
a malfunction. ( When using Mode 2
AC charging cable.)
●Depending on radio wave conditions,
interference may be heard on the radio.
●The current chargi ng condition and the estimated time until charging will
complete can be checked on the
multi-information display.
■Capacity reduction of the hybrid
battery (tracti on battery)
The capacity of the hybrid battery (trac -
tion battery) will dec line gradually when
the hybrid battery (tr action battery) is in use. The rate at which it declines will dif -
fer in accordance with environmental
conditions and the way in which the vehicle is used. Observing the following
can help suppress battery capacity
decline.
●Avoid parking the vehicle in areas with
a high temperature under direct sun - light when the hybrid battery (traction
battery) is fully charged.
●Avoid accelerating and decelerating
frequently and suddenly when EV
driving.
●Avoid frequent driving near the top
speed for EV driving. ( →P.90)
●Leave a low level of charge in the
hybrid battery (trac tion battery) when leaving the vehicle undriven for a long
period of time.
After confirming that EV mode or AUTO EV/HV mode has switched to
HV mode, turn the power switch off.
●Use the charging schedule function as
much as possible in order to fully
charge the hybrid battery (traction bat - tery) immediately bef ore starting off.
( →P.144)
Also, if the hybrid battery (traction bat- tery) capacity reduces, the distance that
can be driven in EV mode or AUTO
EV/HV mode decreases. However, vehi - cle performance does not significantly
become worse.
■When the remaining charge of the
hybrid battery (trac tion battery) is low after charging
In the following situations, the remaining
charge of the hybrid battery (traction battery) after charging completes may
be less than normal in order to protect
the system (the EV dr iving range after the battery is fully charged may be
shorter).*
●Charging is carried out when the out -
side temperature is low or high.
●Charging is carried out immediately
after high-load driv ing or in extreme
heat.
When none of the above situations
apply and there is a drastic drop in the
remaining charge of the hybrid battery
(traction battery) after charging com - pletes, have the veh icle inspected by
any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.*: When this occurs, even if the remain -
ing charge display of the hybrid bat-
tery (traction battery) shows that it is

install the clip.
■Cleaning the air intake vent
●Dust in the air intake vent may inter - fere with the cooling of the DC/DC
converter. If the cooling perfor -
mance/capacity of the DC/DC con - verter becomes limited, the 12-volt
battery may discharge. Inspect and
clean the air intake vent periodically.
●Improper handling of the air intake
vent cover and filter may result in damage to them. If you have any con -
cerns about cleaning the filter, contact
any authorized Toy ota retailer or Toyota authorized repairer, or any reli -
able repairer.
■If “Maintenance required for DCDC
converter cooling parts See Owner’s Manual” is shown on the
multi-information display
●If this warning message is shown on
the multi-informatio n display, remove
the air intake vent cover and clean the filter. ( →P.536)
●After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer shown.
It may take approximately 20 minutes
after the hybrid syst em is started until the warning message disappears. If
the warning message does not disap -
pear, have the vehicle inspected by any authorized Toy ota retailer or
Toyota authorized repairer, or any reli -
able repairer.
WARNING
■When cleaning the air intake vent
●Do not use water or other liquids to
clean the air intake vent. If water is applied to the DC/ DC converter or
other components, a malfunction or
fire may occur.
●Before cleaning th e air intake vent,
make sure to turn the power switch
off to stop the hybrid system.
NOTICE
■When cleaning the air intake vent

8-2. Steps to take in an emergency
When trouble arises
a malfunction, as the hybrid system
will start normally on the second attempt.
●The power switch mode is memorized by the vehicle. When the 12-volt bat-
tery is reconnected , the system will
return to the mode it was in before the 12-volt battery was discharged.
Before disconnecting the 12-volt bat -
tery, turn the power switch off. If you are unsure what mode the
power switch was in before the 12-volt
battery discharged, be especially careful when reconnecting the 12-volt
battery.
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to
European regulations.
●Use a 12-volt batt ery that the case
size is same as the previous one
(LN2), 20 hours rate capacity (20HR) is equivalent (55Ah ) or greater, and
performance rating (CCA) is equiva -
lent (345A) or greater. • If the sizes differ, the 12-volt battery
cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi -
cle is not used is a short time, the 12-
volt battery may discharge and hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If
a 12-volt battery without a handle is used, removal is more difficult.
●When removing the 12-volt battery: → P.508
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery.
• Use the exhaust hose that was
attached to the 12-volt battery before replacing and confirm that it is firmly
connected to the hole section of the
vehicle. • Use the exhaust hole plug included
with the new 12-volt battery or the one
installed on the battery prior to the replacement. (Depending on the new
12-volt battery installed, the exhaust
hole may be plugged.)
For details, consult any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
