panel, rear package tray or floor, or in the
door pockets or glove box when the
hybrid system is started or power switch
modes are changed.
ODo 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 outside the cabin and the doors
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.
OAs 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.
OEven if the electronic key is not inside the
vehicle, it may be possible to start the
hybrid system if the electronic key is near
the window.
OThe 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 auto-
matically be locked after approximately
60 seconds if the doors are not opened
and closed.)
OIf the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.)
OTouching the door lock sensor while
wearing gloves may delay or prevent
lock operation. Remove the gloves and
touch the lock sensor again.
OWhen the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
OUnlocking the vehicle may take more
time if another electronic key is within the
effective range.
