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)
●The hybrid system may not start.
Follow the procedure below to ini-
tialize the system.
1 Shift the shift lever to P.
2 Open and close any of the doors.
3 Restart the hybrid 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.

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 a screen
display
* and by a warning
light. ( P.649)
*: Vehicles with tire inflation pres-
sure display function only
 Vehicles with tire inflation
pressure display function
only: The tire pressure
detected by the tire pressure
warning system can be dis-
played on the multi-informa-
tion display. ( P.98)
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*
*
: Vehicles with tire inflation pres-
sure display function only
●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 (if
equipped)
●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.
