Note for the entry function●
Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow 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 instrument
panel, rear package tray or floor, or in the
door pockets or glove box when the
hybrid system is star ted 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 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. ●
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 po ssible to start the
hybrid system if the el ectronic 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 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 possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.) ●
Touching the door lock sensor while
wearing gloves may delay or prevent lock
operation. ●
When 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.
●
If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft.
(2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)

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 vehicle. To
turn off the alarm, lock all the doors.●
The lock sensor may not work properly if
it comes into contact with ice, snow, mud,
etc. Clean the lock sensor and attempt to
operate it again.●
A sudden approach to the effective
range or door handle may prevent the
doors from being unlocked. In this case,
return the door handle to the original
position and check that the doors unlock
before pulling the door handle again.●
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.■

extended periods●
To prevent theft of the vehicle, do not
leave the electronic key within 6 ft. (2 m)
of the vehicle.●

when operating the system. Do not get
the electronic key too close to the vehicle
when operating the system from the out-
side of the vehicle.

condition of the electronic key, the key may
not be detected correctly and the system
may not operate properly. (The alarm may
go off accidentally, or the door lock pre-
vention function may not operate.)
