■ 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 operation 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
EV 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.188)
● 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.497). 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.
■ If a message regarding the state
of the electronic key or power
switch mode, etc. is shown
