QStopping the hybrid system
Shift the shift lever to P, set the parking brake and press the power switch as

QReplacing the key battery
As the above procedure is a temporary
measure, it is recommended that the electronic key battery be replaced immediately when the battery is
depleted. ( P.486)
QAlarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.

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
light 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 reinstall
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.
QStarting the hybrid system when
the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
QTo prevent 12-volt battery dis-
charge
OTurn off the headlights and the audio
system while the hybrid system is off.
OTurn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
QWhen the 12-volt battery is
removed or discharged
OInformation 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.
OSome systems may require initializa-tion. ( P.582)

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.
QCharging 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.)
QWhen recharging or replacing the 12-volt battery
OIn 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.
OThe hybrid system may not start on
the first attempt after reinstalling the 12-volt battery. In that case, start the hybrid system in the same manner as
when the electronic key does not operate properly ( P.545). This is not
