When trouble arises
8-2. Steps to take in an emergency
If the electronic key does not operate
properly
Use the mechanical key (P. 11 7 )
in order to perform the following
operations:
Locks all the doors
Unlocks the door
Turning the key rearward unlocks
the driver’s door. Turning the key
once again within 3 seconds
unlocks the other doors.
Ensure that the shift position is in P and depress the brake pedal.
Touch the Toyota emblem side
of the electronic key to the
power switch.
When the electronic key is
detected, a buzzer sounds and the
power switch will turn to ON mode.
When the smart key system is
deactivated in customization set-
ting, the power switch will turn to
ACCESSORY mode.
Firmly depress the brake pedal and check that the smart key sys-
tem indicator light (green) turns on (vehicles without multi-informa-
tion display) or is shown on the multi-information display
(vehicles with multi-information display).
If communication between the electronic key and vehicle is
interrupted ( P. 133) or the electronic key cannot be used
because the battery is depleted, the smart key system and
wireless remote control cannot be used. In such cases, the
doors can be opened and the hybr id system can be started by
following the procedure below.

When trouble arises
Make sure the “READY” indicator comes on. If the indicator light
does not come on, contact your Toyota dealer.
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 your
Toyota dealer as soon as possible.
■ Starting the hybrid system when th e 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.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery 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 vehicle is left for a long time, the 12-volt
battery 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 repl acing the 12-volt battery
● In some cases, it may not be possible to unlock the doors using the smart
key system when the 12-volt battery is discharged. Use the wireless 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.
● If the 12-volt battery discharges while the shift position is in P, it may not be
possible to shift the shift position to other positions. In this case, the vehicle
cannot be towed without lifting both front wheels because the front wheels
will be locked. ( P. 486)
● When the 12-volt battery is reconnected, start the hybrid system and con-
firm that the shift position can be changed to each position using the shift
position indicator.
