When bringing an elec tronic key onto an
aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an
electronic key in your bag etc., ensure that
the buttons are not likely to be pressed
accidentally. Pressing a button may cause

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 when the engine is
stopped.
●Battery-saving mode can reduce the
power consumption of electronic keys
that are not used for long periods of time.
(  P.107)
●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 nec-
essary. ( P.341)
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself
(  P.341). However, as there is a danger
that the electronic key may be damaged, it
is recommended that replacement be car-
ried out by your Lexus dealer.
●To avoid serious dete rioration, do not
leave the electronic key within 3 ft. (1 m)
of the following electrical appliances that
produce a magnetic field:
•TVs
