may be affected, preventing the smart
access system with push-button start, wire-
less remote control and immobilizer system
from operating properly. (Ways of coping:
→ P.387) ●
When the electronic key battery is
depleted ●
Near a TV tower, electric power plant,

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 near the ground or

bumper center when the back door is
opened.
• The electronic key is on the instrument
panel, luggage room, 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 vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the door
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle.
●
As long as the electron ic key is within the
effective range, the doors may be locked
or unlocked by anyone.
●
Even 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.
●
The doors may unlock 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 door will automatically 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. Remove the gloves and touch
the lock sensor again. ●
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 that 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.)
• Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( → P.123)●
If the electronic key is inside the vehicle
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
