■Note for the entry function
●Even when the electronic key is within
the effective range (detection areas),
the system may not operate properly
in the following cases:
• The electronic key is too close to the
window or outside door handle, 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 recep-
tion conditions, it may be detected by
the antenna outside the cabin and the
door will become lockable from the
outside, possibly trapping the elec-
tronic key inside the vehicle.
●As long as the electronic key is within
the effective range, the doors may be
locked or unlocked by anyone. How-
ever, 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 possible to start
the engine if the electronic 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 effective range. (The doors
will automatically be locked after
approximately 30 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 pos-
sibility 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 sen-
sor while wearing gloves may prevent
lock or unlock operation.
●When the lock operation is performed
using the lock sensor, recognition sig-
nals will be shown up to two consecu-
tive times. After this, no recognition
signals will be given.
●If the door handle becomes wet while
the electronic key is within the effec-
tive range, the door may lock and
unlock repeatedly. In that case, follow
the following correction procedures to
