4877-2. Steps to take in an emergency
7
When trouble arises
have the vehicle inspected at 
your Toyota dealer as soon as 
possible.
■Starting the hybrid system 
when the 12-volt battery is dis-
charged
The hybrid system cannot be 
started by push-starting.
■To prevent 12-vol t battery dis-
charge
●Turn off the headlights and the 
audio system while the hybrid sys-
tem is off.
●Turn off any unnec essary electri-
cal components when the vehicle 
is running at a low speed for an 
extended period, such as in heavy 
traffic.
■When the 12-volt battery is 
removed or discharged
●Information stor ed in the ECU is 
cleared. When the 12-volt battery 
is depleted, have the vehicle 
inspected at your Toyota dealer.
●Some systems may  require initial-
ization. ( P.531)
■When removing the 12-volt bat-
tery terminals
When the 12-volt battery terminals 
are removed, the information stored 
in the ECU is cleared. Before 
removing the 12-volt battery termi-
nals, contact your Toyota dealer.
■Charging the 1 2-volt battery
The electricity stor ed in the 12-volt 
battery will discharge gradually even 
when the vehicle is not in use, due 
to natural discharge and the drain-
ing effects of certa in electrical appli-
ances. If the vehicle is left for a long 
time, the 12-volt battery may dis-
charge, and the hybrid system may 
be unable to start. (The 12-volt bat-
tery recharges aut omatically while 
the hybrid system is operating.)
■When recharging or replacing 
the 12-volt battery (vehicles 
without smart key system)
The hybrid system may not start on 
the first attempt after the 12-volt bat-
tery has recharged but will start nor-
mally after the second attempt. This 
is not a malfunction.
■When recharging or replacing 
the 12-volt battery (vehicles 
with smart key system)
●In some cases, it 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 c ontrol or the 
mechanical key to lock or unlock 
the doors.
●The hybrid syste m may not start 
on the first attempt after the 12-
volt battery has  recharged but will 
start normally after the second 
attempt. This is n ot a malfunction.
●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 to 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.
■When replacing t he 12-volt bat-
tery
●Use a 12-volt battery that con-
forms to European regulations.
Type A:
Use a battery that the case size is 
same as the previous one (LN1), 20 
hours rate capacity (20HR) is equiv-
alent (45Ah) or greater, and perfor-
mance rating (CCA) is equivalent 
(285A) or greater.
