When the 12-volt battery is dis-
charged, refer to P.539, “If the 12-
volt battery is discharged” and
perform the corr ection procedure.
●When the vehicle is left with the
AC charging cable connected, the
electricity consumption amount of
the 12-volt battery increases due
to controls, such as the system
checking, operating. 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
22 mph (35 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting Sy stem may be dif-
ficult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the Acoustic Vehicle Alert-
ing System is installed on the front
of the vehicle, it may be more diffi-
cult to hear from the rear of the vehi-
cle compared to the front.
■When “Acoustic Vehicle Alert-
ing System Malfunction Visit

■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.518)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.3 gal.
[8.8 L, 1.9 Imp.gal.], when the vehi-
cle is on a level su rface. This value
may vary when the vehicle is on a
slope. Add extra fuel when the vehi-
cle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
the hybrid vehicles incorporate
electromagnetic shielding, and
therefore emit approximately the
same amount of electromagnetic
waves as conventional gasoline
powered vehicles or home elec-
tronic appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Effect of magnetic forces
If objects that generate strong mag-
netic forces, such as large speak-
ers, are placed inside the luggage
compartment or installed nearby,
the generated magnetic forces may
negatively affect t he 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 recharge-
able batteries. The extent at which capacity reduces changes drasti-
cally depending on the environment
(ambient temperature, etc.) and
usage conditions, such as how the
vehicle is driven and how the hybrid
battery (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 battery (traction
battery) capacity reduces, vehicle
performance does not significantly
become worse.
In order to reduce the possibility of
the capacity reducing, follow the
directions listed on P.121, “Capacity
reduction of the hybrid battery (trac-
tion battery)”.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C]) under
the influence of the outside tem-
perature, it may not be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increase etc.

■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.

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.
