■Note for the entr y function (if
equipped)
●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.

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 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
