minutes to recharge the 12-volt
battery of your vehicle.

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)

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
