WARNING
■Back door closer
●In the event that the back door
is left slightly open, the back
door closer will automatically
close it to the fu lly closed posi-
tion. It takes several seconds
before the back door closer
begins to operate. Be careful
not to get fingers caught or any-
thing else in the back door, as
this may cause bone fractures
or other serious injuries.
●Use caution when using the
back door closer as it still oper-
ates when the power back door
system is disabled.
■Power back door
Observe the following precautions
when operating the power back
door. Failure to do so may cause
death or serious injury.
●Check the safety of the sur-
rounding area to make sure
there are no obs tacles or any-
thing that could cause any of
your belongings to get caught.

may cause death or serious injury.
●Check the safety of the sur-
rounding area to make sure
there are no obs tacles or any-
thing that could cause any of
your belongings to get caught.
●Exhaust gasses cause the
exhaust pipes to become quite
hot. When operating the Hands
Free Power Back Door, be care-

pipe.

1323-2. Opening, closing and locking the doors
■Effective range (areas within
which the electronic key is
detected)When locking or unlocking the
doors
The system can be operated when
the electronic key is within about 2.3
ft. (0.7 m) of an outside front door
handle and back door. (Only the
doors detecting t he key can be
operated.)
When starting the engine or
changing engine switch modes
The system can be operated when
the electronic key is inside the vehi-
cle.
■Alarms and warning messages
A combination of e xterior and inte-
rior alarms as well as warning mes-
sages shown on the
multi-information display are used to
prevent theft of the vehicle and acci-
dents resulting from erroneous
operation. Take appropriate mea-
sures in response to any warning
message on the multi-information
display. ( P.442)
When only an ala rm sounds, cir-
cumstances and c orrection proce-
dures are as follows.
●When an exterior alarm sounds
once for 5 seconds
●When an interior alarm sounds
continuously
■Battery-saving function
The battery-saving function will be
activated in ord er to prevent the
electronic key battery and the vehi-
cle battery from being discharged
while the vehicle is not operated for
a long time.
●In the following situations, the
smart key system may take some
time to unlock the doors.
• The electronic key has been left in
an area of approxi mately 6 ft. (2
m) of the outside of the vehicle for
10 minutes or longer.
• The smart key system has not been used for 5 days or longer.

■Turning an electronic key to
battery-saving mode
When battery-savi ng mode is set,
battery depletion is minimized by
stopping the electronic key from
receiving radio waves.
Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator flashes 4 times.
While the battery-saving mode is
set, the smart key system cannot be
used. To cancel the function, press
any of the electronic key buttons.
■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 engine immobilizer sys-
tem from operating properly. (Ways
of coping: P.463)
●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 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 wirel
ess keys (that
emit radio waves) are being used
nearby
●When carrying the electronic key
together with the following devices
that emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless
communication devices
• 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 wit h 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 on the instru-
ment panel, luggage compart-
ment, floor, or in the door pockets
or glove box when the 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 out-

1343-2. Opening, closing and locking the doors
side the cabin and the door 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 electronic key is not
inside the vehicle, it may be possi-
ble to start the engine if the elec-
tronic 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 w ithin the effec-
tive range. (The doors will auto-
matically 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 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 or unlock
sensor while wearing gloves may
prevent lock or unlock 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 that
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 bat- tery-saving mode to disable the
smart key system. (
P.133)
●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 vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it comes into contact
with ice, snow, m ud, etc. Clean
the lock sensor and attempt to
operate it again, or use the lock
sensor on the lower part of the
door handle.
●A sudden handle operation or a
handle operation immediately
after entering the effective range
may prevent the doors from being
unlocked. Touch the door unlock
sensor and check that the doors
are unlocked befo re 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. ( P.494)
●Setting the electronic key to bat-
tery-saving mode helps to reduce
key battery depletion. ( P.133)
■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 vehi-
cle.
Depending on the position and hold-
ing condition of the electronic key,
the key may not be detected cor-
