The 12-volt battery is located in
the right-hand side of luggage
compartment.
■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the power switch on
the charger is off when connecting
and disconnecting the charger
cables to the 12-volt battery.
■After recharging/reconnecting
the 12-volt battery (vehicles
with smart key system)
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to
lock/unlock the doors.
●Start the hybrid system with the
power switch in ACC. The hybrid
system may not start with the
power switch turned off. How-
ever, the hybrid system will oper- ate normally from the second
attempt.
●The power switch mode is
recorded by the vehicle. If the 12-
volt battery is reconnected, the
vehicle will return the power
switch mode to the status it was in
before the 1
2-volt battery was dis-
connected. Make sure to turn off
the power switch before discon-
nect the 12-volt battery. Take
extra care when connecting the
12-volt battery if the power switch
mode prior to discharge is
unknown.
If the hybrid system will not start
even after multiple attempts at all
methods above, contact your
Toyota dealer.

Maintenance and care
■When rotating the tires (vehi-
cles with tire pressure warning
system)
Make sure that the power switch is
OFF. If the tires are rotated while
the power switch is in ON, the tire
position informa tion will not be
updated. If this accidentally occurs,
either turn the power switch to OFF
and then to ON, or initialize the sys-
tem after checking that the tire pres-
sure is properly adjusted.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
 If the tire pressure drops
below a predetermined level,
the driver is warned by a
screen display and a warning
light. ( P.630)
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.101)
The illustration used is intended
as an example, and may differ
from the image that is actually
displayed on the multi-informa-
tion display.
■Routine tire inflation pressure
checks
The tire pressure warning system
does not replace routine tire inflation
pressure checks . Make sure to
check tire inflation pressure as part
of your routine o f daily vehicle
checks.
■Tire inflation pressure
●It may take a few minutes to dis-
play the tire inflation pressure
after the power switch is turned to
ON. It may also take a few min-
utes to display the tire inflation
pressure after infl ation pressure
has been adjusted.
●Tire inflation pressure changes
with temperature.
The displayed values may also be
different from the values mea-
sured using a tire pressure gauge.
■Situations in which the tire
pressure warning system may
not operate properly
●In the following cases, the tire
pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-support ed run-flat tire
is equipped.
• If a window tint that affects the radio wave signals is installed.

system (if equipped)

5827-3. Do-it-yourself maintenance
• If there is a lot of snow or ice on
the vehicle, particularly around the
wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the speci-
fied level.
• If wheels without tire pressure warning valves a nd transmitters
are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure
warning computer.
●Performance may be affected in
the following situations.
• Near a TV tower, electric power plant, gas station, radio station,
large display, airpo rt or other facil-
ity that generates strong radio
waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication
device
If tire position information is not cor-
rectly displayed due to the radio
wave conditions, the display may be
corrected by driving and changing
the radio wave conditions.
●When the vehicle is parked, the
time taken for the warning to start
or go off could be extended.
●When tire inflation pressure
declines rapidly for example when
a tire has burst, the warning may
not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure
warning system will change in
accordance with th e conditions
under which it was initialized. For
this reason, the system may give a
warning even if the tire pressure
does not reach a low enough level,
or if the pressure is higher than the
pressure that was adjusted to when
the system was initialized.
When replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer and the tire
pressure warning system must
be initialized. ( P.585)
■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and tr ansmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.

each tire on the multi-information
display while the tire pressure
warning system determines the
position.
8Drive straight (with occa-
sional left and right turns) at
approximately 25mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information
display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, initializat ion can be com-
pleted by driving for a long time.
However, if initia lization does not
complete after driving for 1 hour or
more, park the vehicle in a safe
place for approximately 20 minutes
and then drive th e vehicle again.
■When initializing
●Initialization is performed while
driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure. Also, make sure the
tires are cold before carrying out
initialization or tir e inflation pres-
sure adjustment.
●The tire pressure warning system
can be initialized by yourself, but
depending on the driving condi-
tions and driving environment, ini-
tialization may take some time to
complete.
■The initialization operation
●If you have accidentally turned the
power switch to OFF during initial-
ization, it is not necessary to
restart the initia lization again as
initialization will restart automati-
cally when the power switch has
been turned to ON for the next time.
●If you accidentally perform initial-
ization when initia
lization is not
necessary, adjust the tire inflation
pressure to the s pecified level
when the tires are cold, and con-
duct initialization again.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-information display, if
the inflation pressure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not initia lized properly
●In the following situations, initial-
ization may take longer than usual
to be completed or may not be
possible. Normally, initialization
completes within approximately
30 minutes.
• Vehicle is not driven at approxi- mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved
roads
• Vehicle is driven near other vehi- cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f your vehicle
over those of other vehicles.
• If the vehicle is driven in heavy traffic or another situation where
other vehicles are driven close by,
it may take time f or the system to
recognize the ti re pressure warn-
ing valve and transmitters of your
vehicle over those of other vehi-
cles.
If initialization does not complete
after driving for 1 hour or more, park
the vehicle in a safe place for
approximately 20 minutes and then
drive the vehicle again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so p erform the ini-
tialization procedure again from
the beginning.
●In the following situations, initial-

ization will not be started or was
not completed properly and the
system will not operate properly.
Perform the initialization proce-
dure again.
• If, when attempting to start initial-
ization, the tire pressure warning
light does not blink 3 times.
• If, when the vehicle has been
driven for about 20 minutes after
performing initialization, the tire
pressure warning light blinks for
approximately 1 minute and then
illuminates.
If the inflation pressure of each tire
is still not displayed, have the vehi-
cle inspected by your Toyota dealer.
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID codes,
perform the following procedure.
1 Park the vehicle in a safe
place, wait for approximately 20 minutes, and then start
the hybrid system.
