confinement prevention function is acti-
vated so the trunk can be opened. In
order to prevent theft, take all electronic
keys with you when leaving the vehicle.
●If the electronic key is put in the trunk with
all the doors locked, the key may not be
detected depending on the location of
the key and the surrounding radio wave
conditions. In this case, the key confine-
ment prevention function cannot be acti-
vated, causing the doors to lock when the

Before driving
take some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of the
outside of the vehicle for 10 minutes or
longer.
• The smart access system with push-but-
ton start has not been used for 5 days or
longer.
●If the smart access system with push-but-
ton start has not been used for 14 days or
longer, the doors cannot be unlocked at
any doors except the driver’s door. In this
case, take hold of the driver’s door han-
dle, or use the wireless remote control or
the mechanical key, to unlock the doors.
■Turning an electronic key to bat-
tery-saving mode

depletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
Press twice while pressing and holding . Confirm that the electronic key indica-
tor flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function,

■Conditions affe cting operation
The smart access system with push-button
start uses weak radio waves. In the following
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 engine immobilizer system
from operating properly. (Ways of coping:
 P.442)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant, gas station, radio stat
ion, large display,
airport or other fac ility that generates
strong radio waves or electrical noise
●When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device
●When the electronic key is in contact
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
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio
waves) are being used nearby
●When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or
metallic objects are attached to the rear
window
●When the electronic key is placed near a
battery charger or electronic devices
●When the vehicle is parked in a pay park-
ing spot where radio waves are emitted.
■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 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

1163-2. Opening, closing and locking the doors and trunk
engine is started or engine 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 electron ic 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 possible to start the
engine if the electronic key is near the
window.
●The doors may unlock or lock if a large
amount of water spla shes 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 d oors 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.)
• Set the electronic key to battery-saving mode to disable the smart access system
with push-button start. ( P.115)
●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
to unlock the doors after the door handle
is gripped.
■When the vehicle is not driven for
extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 6 ft. (2 m)
of the vehicle.
●The smart access system with push-but-
ton start can be deactivated in advance.
●Setting the electronic key to battery-sav-
ing mode helps to reduce key battery
depletion. ( P.115)
■To operate the system properly
●Make sure to carry the electronic key
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.
Depending on the position and holding
condition of the electr onic 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.)
●Do not leave the electr onic key inside the
trunk.

ton start or wireless remote control.
The driving position will move to the
recorded position (not including the steer-
ing wheel and head-up display [if
equipped]). However, the seat will move to a position slightly behind the recorded
position in order to make entering the vehi-
cle easier.
If the driving position is in a position that
has already been recorded, the seat and
outside rear view mirrors will not move.

tered for each electronic key. Therefore,
the driving position that is recalled may
be different depending on the key being
carried.
●If a door other than the driver’s door is
unlocked with the smart access system
with push-button start, the driving posi-
tion cannot be recalled. In this case, press

power window after checking to make
sure that there is no possibility of any
passenger having any of their body
parts caught in the window. Also do
not let a child operate window by the
wireless remote control or mechanical
key. It is possible for children and other
passengers to get caught in the power
window.
