Mechanical keys
Key number plate
■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 shown on the
multi-information display when the
engine is stopped.
●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.109)
●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. ( P.456)
• 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.
●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
• Recharging cellular phones or cordless phones
• 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.
■Replacing the battery
 P.456
■If “A New Key has been Regis-
tered Contact Your Dealer for

■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following cases:
• The electronic key is too close to the window or outside door han-
dle, near the ground, or in a high
place when the doors are locked
or unlocked.
• The electronic key is on the instru- ment panel, luggage cover or
floor, or in the door pockets or
glove box when the engine is
started or engine switch modes
are changed.
●Do not leave the electronic key on
top of the instrument panel or near
the door pockets when exiting the
vehicle. Depending on the radio
wave reception conditions, it may
be detected by the antenna out-
side the cabin and the door will
become lockable from the outside,
possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is
within the effective range, the
doors may be locked or unlocked
by anyone. However, only the
doors detecting the electronic key
can be used to unlock the vehicle.
●Even if the electronic key is not
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic key is near the window.
●The doors may unlock or lock if a
large amount of water splashes on
the door handle, such as in the
rain or in a car wash when the
electronic key is within the effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the
doors are not opened and closed.)
●If the wireless remote control is
used to lock the doors when the
electronic key is near the vehicle,
there is a possibilit y that the door
may not be unlocked by the entry
function. (Use the wireless remote
control to unlock the doors.)
●Touching the door lock or unlock
sensor while wearing gloves may
prevent lock or unlock operation.

Before driving
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recognition signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective range, the door may
lock and unlock repeatedly. In that
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 6 ft. (2 m) or more away from
