influence of the outside temperature, it may not be possible to start the hybrid system. In this case, try to start the
hybrid system again after the tem- perature of the hybrid battery increases due to the outside tempera-
ture increase, etc.

minutes to recharge the 12-volt
battery of your vehicle.
6 Vehicles with a smart entry &
start system: Open and close
any of the doors of your vehicle
with the power switch OFF.
7 Maintain the engine speed of
the second vehicle and start the
hybrid system of your vehicle by
turning the power switch to ON.
8 Make sure the “READY” indica-
tor comes on. If the indicator
does not come on, contact any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
9 Once the hybrid system has
started, remove the jumper
cables in the exact reverse
order from which they were con-
nected.
10 Close the exclusive jump start-
ing terminal cover and install the
fuse box cover to its original
position.
Once the hybrid system starts,
have the vehicle inspected at any
authorized Toyota retailer or Toyota
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.440)
■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
p owe r swi t ch wa s i n be f or e t he 1 2- v ol t 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.
●When removing the 12-volt battery:  P. 3 3 0
●After replacing, firmly attach the fol- lowing items to the exhaust hole of the
12-volt battery. • Use the exhaust hose that was attached to the 12-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 12-volt battery
prior to the replacement. (Depending
on the 12-volt battery to be replaced, the exhaust hole may be plugged.)

WARNING
■When removing the 12-volt bat-
tery terminals
Always remove the negative (-) termi- nal first. If the positive (+) terminal
contacts any metal in the surrounding area when the positive (+) terminal is removed, a spark may occur, leading
to a fire in addition to electrical shocks and death or serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to
prevent accidentally igniting the flam- mable gas that may be emitted from the 12-volt battery:
