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

■Turning an electronic key to bat-
tery-saving mode
When battery-saving mode is set, battery
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.437)
●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

1143-2. 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.113)
●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.113)
■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.

WARNING
■When adjusting the seat position
●Take care when ad justing the seat
position to ensure that other passen-
gers are not injured by the moving
seat.
●Do not put your hands under the seat
or near the moving parts to avoid
injury.
Fingers or hands may become
jammed in the se at mechanism.
●Make sure to leave enough space
around the feet so they do not get
stuck.
■Seat adjustment
To reduce the risk of sliding under the lap
belt during a collision, do not recline the
seat more than necessary.
If the seat is too reclined, the lap belt may
slide past the hips and apply restraint
forces directly to the abdomen, or your
neck may contact the shoulder belt,
increasing the risk of death or serious
injury in the event of an accident.
Adjustments should not be made while
driving as the seat may unexpectedly
move and cause the driver to lose control
of the vehicle.
■Operating the front passenger’s seat
from the driver’s seat or rear seat
Do not operate the front passenger’s seat
when a passenger is seated in it. In addi-
tion, do not let anyone sit down in the
front passenger’s seat while the seat is
being operated or when the head
restraint is being folded. The front pas-
senger may catch their legs between the
instrument panel and seat, or the head
restraint may interfer e with their head,
resulting in injury.
■When the front passenger’s seat is
folded forward
If the outside rear view mirror is difficult
to see, due to the position of the front
passenger’s seat, move the front passen-
ger’s seat to an appropriate position.
Doing so may lead to mishandling of the
vehicle and cause an accident, resulting
in death or serious injury.
NOTICE
■Operating the front passenger’s seat
from the driver’s seat or rear seat
Before operating the front passenger’s
seat, make sure that there is no luggage
or any other objects on the seat or in the
footwell that could prevent its operation.
Such items may result in excess force
being applied, causing damage to the
seat and/or the luggage.
