■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 near the ground or in a high place, or too
close to the center of the rear
bumper when the trunk is opened.
• The electronic key is on the instru- ment panel, rear package tray 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 co nditions, 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.
●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 following correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca-
tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to bat- tery-saving mode to disable the
smart key system. ( P.113)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a
message may be shown on the
multi-information display and a
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it co mes into contact
with ice, snow, mud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked before pulling the
door handle again.

Before driving
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.
■When the vehicle is not driven
for extended periods
●To prevent theft of the vehicle, do
not leave the electronic key within
6 ft. (2 m) of the vehicle.
●The smart key system can be
deactivated in advance. ( P.548)
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P. 1 1 3 )
■To operate the system properly
●Make sure to carry the electronic
key when operating the system.
Do not get the electronic key too
close to the vehicle when operat-
ing the system from the outside of
the vehicle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention function may not operate.)
●Do not leave the electronic key
inside the trunk.
The key confinement prevention
function may not operate, depend-
ing on the location of the key (the
inside edge of the trunk), condi-
tions (inside a metal bag, close to
metallic objects) and the radio
waves in the surrounding area.
