●When carrying a portable radio,
cellular phone, cordless phone or
other wireless communication
device
●When the electronic key is in con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is

■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

floor, or in the door pockets or
glove box when the hybrid system
is started or power switch modes
are changed.
●Do not leave the electronic key on
top of the instrument panel or near
the door pockets when exiting the

wave reception conditions, it may
be detected by the antenna out-

within the effective range, the
doors may be locked or unlocked
by anyone. However, only the
doors detecting the electronic key
