QBattery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic key
battery and the 12-volt battery from being
discharged while the vehicle is not in opera-
tion for a long time.
OIn the following situations, the smart
access system with push-button start may
take some time to unlock the doors.
• The electronic key has been left within
approximately 6 ft. (2 m) of the outside of

ing situations, the communication between
the electronic key and the vehicle may be
affected, preventing the smart access sys-
tem with push-button start, wireless remote
control and immobilizer system from oper-
ating properly.
(Ways of coping:  P.389)

with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins

metallic objects are attached to the rear
window
OWhen the electronic key is placed near a
battery charger or electronic devices
OWhen the vehicle is parked in a pay park-

QNotes for the entry function
OEven when the electronic key is within the

1183-2. Opening, closing and locking the doors and trunk
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 in a high place, or too close to the center
of the rear bumper when the trunk is
opened.
• 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 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.
OIf 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.)
• Set the electronic key to battery-saving
mode to disable the smart access system
with push-button start. ( P.117)
OIf 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.
OThe 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.
OA 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.
QWhen the vehicle is not driven for
extended periods
OTo prevent theft of the vehicle, do not
leave the electronic key within 6 ft. (2 m)
of the vehicle.
OThe smart access system with push-but-
ton start can be deactivated in advance.
OBattery-saving mode can reduce the
power consumption of electronic keys.
