Owners Manual_USA_M0C052_entery recharges aut
omatically while
the hybrid system is operating.)
■When recharging or replacing
the 12-volt battery
●In some cases, i t may not be pos-
sible to unlock the doors using the
smart key system when the 12-
volt battery is discharged. Use the
wireless remote control or the
mechanical key to lock or unlock
the doors.
●The hybrid system may not start
on the first attem pt after reinstall-
ing the 12-volt battery. In that
case, start the hy brid system in
the same manner as when the
electronic key does not operate
properly ( P.528). This is not a
malfunction, as the hybrid system
will start normally on the second
attempt.
●The power switch mode is memo-
rized by the vehicle. When the 12-
volt battery is reconnected, the
system will return to the mode it
was in before the 12-volt battery
was discharged. Before discon-
necting the 12-volt battery, 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 recon-
necting the 12-volt battery.
●Some systems may require initial-
ization. ( P.571)
■When replacing the 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
●Use a battery 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
equivalent (345A) or greater.
• If the sizes differ, the 12-volt bat- tery cannot be pr operly secured.
• If the 20 hour rate capacity is low,
even if the time period where the
vehicle 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 bat-
tery
●Use a 12-volt battery with a han-
dle. If a 12-volt battery without a
handle is used, removal is more
difficult.
●When removing the 12-volt bat-
tery:
P.463
●After replacing, firmly attach the
following items to the exhaust hole
of the 12-volt battery.
• Use the exhaust hose that was
attached to the 1 2-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 12-volt battery
replaced or the one installed on
the battery prior to the replaced.
(Depending on the 12-volt battery
to be replace, t he exhaust hole
may be plugged.)
For details, consult your Toyota
dealer.
