If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 591)
● Starting the hybrid system: P. 592
■ Electronic key battery depletion
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. ( P. 114)
● As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 493)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Charging cellular phones or cordless phones
• Induction cookers
• Table lamps

mode (the hybrid system is not operating) for more than an hour with the
shift position in P, the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent the 12-volt battery from discharging. Do
not leave the vehicle with the “POWER” switch in ACCESSORY or ON mode
for long periods of time when the hybrid system is not operating.
■ Sounds and vibrations specific to a hybrid vehicle

Maintenance and care
■
After charging/reconnecting the 12-volt battery
● Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
● Start the hybrid system with the “POWER” switch in ACCESSORY mode.
The hybrid system may not start with the “POWER” switch turned off.
However, the hybrid system wi ll operate normally from the second
attempt.
● The “POWER” switch mode is recorded by the vehicle. If the 12-volt bat-
tery is reconnected, the vehicle will return the “POWER” switch mode to
the status it was in before the 12-volt battery was disconnected. Make
sure to turn off the power before disconnect the 12-volt battery. Take
extra care when connecting the 12-volt battery if the “POWER” switch
mode prior to discharge is unknown.
● Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.

MessageDetailsCorrection procedure
Charging has been
stopped because of the
high energy consumption
of electrical compo-
nents, such as the head-
lights. Switch the electrical
appliance OFF, and
restart charging by fol-
lowing the procedure on
P. 80.
If the message is still
displayed, the 12-volt
battery may have a low
charge.
In this event, turn the
“POWER” switch OFF
approximately 15 min-
utes after starting the
hybrid system, and
restart charging.
Charging has been
stopped because of
extremely low voltage,
possibly caused by the
plug not being inserted

procedure
Charging has been
stopped because of a
problem with the charg-
ing cable. If the charging cable is
not a genuine Toyota

charging using a charg-
ing station (other than a
Toyota dealer), try charg-
ing with a genuine Toyota

tect the battery). If the desired charge
level has not been
achieved, restart charg-
ing by following the pro-
cedure on P. 80 after the
