reliable repairer.
■ Stopping the hybrid system

When trouble arises
Start the engine of the second vehicle. Increase the engine speed
slightly and maintain at that level for approximately 5 minutes to
recharge the 12-volt battery of your vehicle.
Maintain the engine speed of the second vehicle and start the
hybrid system of your vehicle by turning the power switch to ON
mode.
Make sure the “READY” indicator comes on. If the indicator light
does not come on, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the
fuse box cover to its original position.
When installing, first hook the fuse box cover onto the two rear tabs.
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 discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical 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
● 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 battery
has recharged but will start normally 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 battery,
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 recon-
necting the 12-volt battery.
