■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.

Before driving
■If a message regarding the state
of the electronic key or power
switch mode, etc. is shown
To prevent trapping the electronic
key inside the vehicle, leaving the
vehicle carrying the electronic key
on your person without turning the
power switch to OFF or other pas-
sengers from unintentionally taking
the key out of the vehicle, etc., a
message that prompts the user to
confirm the state of the electronic
key or power switch mode may be
shown on the multi-information dis-
play. In those cases, follow the
instructions on the display immedi-
ately.
■If “Key Battery Low Replace
Key Battery” is displayed on
the multi-information display
The electronic key has a low bat-
tery. Replace the electronic key bat-
tery. ( P.538)
■Replacing the battery
 P.538
■Confirmation of the registered
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.
●Do not attach me tallic or mag-
netic materials to the keys or
place the keys close to such
materials.
●Do not disassemble the keys.
●Do not attach a sticker or any-
thing else to the surface of the
electronic key.
●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.
Radio waves emitted from electric
appliances within 3.9 in. (10 cm)
of the electronic key may interfere
with the key, causing the key to
not function properly.
■In case of a smart key system
malfunction or other key-
related problems

The second reminder will not be
activated if a rear door was opened
before the doors are locked.
However, if a rear door is opened
and then closed within approxi-
mately 2 seconds, the rear seat
reminder function may not operate.

lock is set.
WARNING
■To prevent an accident
Observe the following precautions
while driving the vehicle.
Failure to do so may result in a
door opening and an occupant
could be thrown out of the vehicle,
resulting in death or serious
injury.
●Ensure that all doors are prop-
erly closed and locked.
●Do not pull the inside handle of
the doors while driving.
Be especially careful for the
front doors, as the doors may
be opened even if the inside
lock buttons are in locked posi-
tion.
●Set the rear door child-protector
locks when children are seated
in the rear seats.
■When opening or closing a
door
Check the surroundings of the
vehicle such as whether the vehi-
cle is on an incline, whether there
is enough space for a door to
open and whether a strong wind
is blowing. When opening or clos-
ing the door, hold the door handle
tightly to prepare for any unpre-
dictable movement.

tact with, or is covered by the fol-
lowing metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have alumi-
num foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
