■Conditions affecting operation
The smart key system uses weak
radio waves. In the following situa-
tions, the communication between
the electronic key and the vehicle
may be affected, preventing the
smart key system, wireless remote
control and immobilizer system from
operating properly. (Ways of coping:
 P.527)
●When the electronic key battery is
depleted
●Near a TV tower, electric power
plant, gas station , radio station,
large display, airpo rt or other facil-
ity 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 con-
tact with, or is covered by the fol-
lowing metallic objects
• Cards to which al uminum foil is
attached
• Cigarette boxes that have alumi- num 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 electronic key or a wire- less key that emits radio waves
• Personal computers or personal
digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic con-
tent or metallic objects are
attached to the rear window
●When the electronic key is placed
near a battery charger or elec-
tronic devices
●When the vehicle is parked in a
pay parking spot where radio
waves are emitted.
■Note for the entry function
●Even when the electronic key is
within the effective range (detec-
tion areas), the system may not
operate properly in the following
cases:
• The electronic key is too close to the window or outside door han-
dle, 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.
• The electronic key is on the instru- ment panel, or 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 out-
side 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 electro nic key is not
inside the vehicle, it may be possi-
ble to start the hybrid system if the
electronic 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 effec-
tive range. (The doors will auto-
matically be locked after
approximately 60 seconds if the

1313-2. Opening, closing and locking the doors and tailgate

Before driving
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 possib ility that the door
may not be unlocke d by the entry
function. (Use the wireless remote
control to unloc k the doors.)
●Touching the door lock sensor
while wearing gloves may delay or
prevent lock operation.
●When the lock op eration is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In this
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 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
key system. ( P.129)
●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-informatio n display and a
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it com es into contact
with ice, snow, mud, etc. Clean
the lock sensor and attempt to
operate it again.
●A sudden approach to the effec-
tive range or door handle may pre-
vent 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 key system can be
deactivated in advance.
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.129)
■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 operat-
ing the system from the outside of
the vehicle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
rectly and the system may not oper-
ate properly. (The alarm may go off
accidentally, or the door lock pre-
vention function m ay not operate.)
■If the smart key system does
not operate properly
●Locking and unlocking the doors
and tailgate: P. 5 2 7
●Starting the hybrid system:
P. 5 2 8
■Customization
Some functions can be customized.
(  P.561)
■If the smart key system has
been deactivated in a custom-
ized setting
●Locking and unlocking the doors
and opening the tailgate:
Use the wireless remote control or
mechanical key. ( P.113, 121,
527)

posture.
Adjustment procedureWARNING
■When adjusting the seat posi-
tion
●Take care when adjusting the
seat position to ensure that
other passengers 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 seat 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 se at more than
necessary.
If the seat is too reclined, the lap
belt may slide past the hips and
apply restraint for ces directly to
the abdomen, or your neck may
contact the shoulder belt, increas-
ing 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.
