7-2. Steps to take in an emergency
authorized repairer, or any reliable  
repairer as soon as possible.
■Starting the hybrid system when  the 12-volt battery is discharged 
The hybrid system cannot be started by  
push-starting.
■To prevent 12-volt battery dis- charge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical components when the vehicle is run-ning at a low speed for an extended  
period, such as in heavy traffic.
■When the 12-volt battery is  removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is depleted, have the vehicle inspected  
at any authorized Toyota retailer or  Toyota authorized repairer, or any reli-able repairer.
●Some systems may require initializa-tion. ( P.505)
■When removing the 12-volt battery  
terminals 
When the 12-volt battery terminals are  removed, the information stored in the  
ECU is cleared. Before removing the 12- volt battery terminals, contact any  
authorized Toyota retailer or Toyota  authorized repairer, or any reliable repairer.
■Charging the 12-volt battery 
The electricity stored in the 12-volt bat- tery will discharge gradually even when the vehicle is not in use, due to natural  
discharge and the draining effects of  certain electrical appliances. If the vehi-cle is left for a long time, the 12-volt bat- 
tery may discharge, and the hybrid  system may be unable to start. (The 12-volt battery recharges automatically  
while the hybrid system is operating.)
■When recharging or replacing the 
12-volt battery (vehicles with a  smart entry & start system)
●In some cases, it may not be possible to unlock the doors using the smart entry & start system when the 12-volt  
battery is discharged. Use the wire- less remote control or the mechanical key to lock or unlock the doors.
●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.
●The power switch mode is memorized by the vehicle. When the 12-volt bat- 
tery is reconnected, the system will  return to the mode it was in before the 12-volt battery was discharged.  
Before disconnecting the 12-volt bat- tery, 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 reconnecting the 12-volt  
battery.
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt 
battery (European Regulations).
●Use a battery that the case size is 
same as the previous one, 20 hour  rate capacity (20HR) is equivalent or greater, and performance rating  
(CCA) is equivalent or greater. Check  the label on top of the battery for the battery size and specifications (ex.  
LN0, 35Ah, 264A). • If the sizes differ, the 12-volt battery cannot be properly secured. 
• If the 20 hour rate capacity is low,  even if the time period where the vehi-cle is not used is a short time, the 12- 
volt battery may discharge and the  hybrid system may not be able to start.
●Use a ventilation type calcium battery
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
