■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 displayed on the
multi-information display when the hybrid system stops.
●To reduce key ba
ttery 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.205)
●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 control 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.538). 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.

ately.

key number
The number of keys already regis-
tered to the vehicle can be con-
firmed. Ask your Toyota dealer for
details.
■If “A New Key has been Regis-
tered Contact Your Dealer for
Details” is displayed on the
multi-information display
This message will be displayed
each time the driver’s door is
opened when the doors are
unlocked from the outside for
approximately 10 days after a new
electronic key has been registered.
If this message is displayed but you
have not had a new electronic key
registered, ask your Toyota dealer
to check if an unknown electronic
key (other than those in your pos-
session) has been registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject
them to strong shocks or bend
them.
●Do not expose the keys to high
temperatures for long periods of
time.
●Do not get the keys wet or wash
them in an ultrasonic washer,
etc.

materials.
●Do not disassemble the keys.
●Do not attach a sticker or any-
thing else to the surface of the

●Do not place the keys near
objects that produce magnetic
fields, such as TVs, audio sys-
tems and induction cookers.
●Do not place the keys near
medical electrical equipment
such as low-fr equency therapy
equipment or microwave ther-
apy equipment, and do not
receive medical attention with
the keys on your person.
■Carrying the electronic key
on your person
Carry the electronic key 3.9 in.
(10 cm) or more away from elec-
tric appliances that are turned on.

your vehicle.
To stop the alarm, press any button on the electronic key.

key of the vehicle if traveling
to a location with unreliable
communications.
 If the smartphone battery is
depleted, the smartphone
cannot be used as Digital

be sure to charge the smart-
phone prior to going out.
 The Digital Key system is
related to the smart key sys-
tem. If the smart key system
has been deactivated in the
vehicle customization setting,
the Digital Key will also be
disabled.
 Depending on the radio wave
environment, the Digital Key
may not be able to be used.
( P.205)
 When transferring vehicle
ownership, make sure to
delete the Digital Keys.
 If the vehicle is not operated
for 14 days or more, the Digi-
tal Key will not connect auto-
matically. Therefore, it may
take some time before the
system operates after a door
handle is touched.
 A part of the services may be
stopped for a certain period of
time due to server mainte-
nance. However, registered
Digital Keys can be used
during the maintenance.
 A smartphone with the Digital Key App enabled will be able
to lock and unlock the doors,
start the hybrid system and

phone or allow it to be stolen.
If the smartphone is lost or
stolen, contact your Toyota
dealer immediately.

Toyota dealer for an inspec-
tion or repairs, make sure to
bring an electronic key.
 With the Digital Key alone, no
vehicle lights will illuminate
when approached to the vehi-
cle. Also, with the Digital Key
