ing pattern change s and the warn-
ing sounds for a certain period of
time.
●A person inside the vehicle opens
a door or hood, or unlocks the
vehicle using an inside lock but-
ton.
●The 12-volt battery is recharged or
replaced when the vehicle is
locked. ( P.469)
■Alarm-operated door lock
In the following cases, depending
on the situation, th e door may auto-
matically lock to p revent improper
entry into the vehicle:
●When a person remaining in the
vehicle unlocks the door and the
alarm is activated.
●While the alarm i s activated, a
person remaining in the vehicle

NOTICE
■To ensure the system oper-
ates correctly
Do not modify or remove the sys-
tem. If modified or removed, the
proper operation of the system
cannot be guaranteed.

1283-1. Key information
3-1.Key information
The following keys are provided
with the vehicle.Electronic keys
• Operating the smart key system ( P.148)
• Operating the wireless remote control function ( P.130)
Mechanical keys

■When riding in an aircraft
When bringing an electronic key
onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■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 and a
message will be dis played on the
multi-information display when the hybrid system stops.
●To reduce key battery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. (
P.150)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote contro l does not oper-
ate.
• The detection area becomes smaller.
• The LED indicator on the key sur- face does not turn on.
You can replace the battery by your-
self ( P.425). However, as there is
a danger that the electronic key may
be damaged, it is recommended
that replacement is carried out by
your Toyota dealer.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
●If the electronic key is near the
vehicle for longer than necessary,
even if the smart key system is not
operated, the key battery may
become depleted faster than nor-
mal. When not operating the
smart key system, it is recom-
mended to not stay with the elec-
tronic key near the vehicle longer
than necessary.
