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

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.

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)

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

lid may cause the lid to suddenly shut
again after it is opened.
■Trunk easy closer (vehicles with
power trunk lid)
In the event that the trun k lid is left slightly
open, the trunk easy closer will automati-
cally close it to the fully closed position. It
takes several seconds before the trunk
easy closer begins to operate. Be careful
not to catch fingers or anything else in
the trunk lid, as this may cause bone frac-
tures or other serious injuries.

denly shut after it opens automatically.
Make sure the trunk lid is fully open
and secure before using the trunk.
●In the following situations, the power
trunk lid may detect an abnormality
and automatic operation may be
stopped. In this case, the trunk lid has
to be operated manually. Take extra
care in this situat ion, as the stopped
trunk lid may suddenly shut, causing an
accident.
• When the trunk lid contacts an obsta- cle
• When the battery voltage suddenly drops, such as when the engine switch
is turned to IGNITION ON mode or
the engine is started during automatic
operation
