3-2. Opening, closing and locking the doors
●Interior buzzer sounds continuously
■Battery-saving function
The battery-saving function will be acti-
vated in order to prevent the electronic
key battery and the vehicle battery from
being discharged while the vehicle is not
operated for a long time.
●In the following situations, the smart
entry & start system may take some
time to unlock the doors.
• The electronic key has been left within
approximately 3.5 m (11 ft.) of the out-
side of the vehicle for 2 minutes or
longer.
• The smart entry & start system has
not been used for 5 days or longer.
●If the smart entry & start system has
not been used for 14 days or longer,
the doors cannot be unlocked from
any door except the driver’s door. In
this case, hold the driver’s door han-
dle, or use the wireless remote control
or mechanical key to unlock the
doors.
■Electronic key battery-saving func-
tion
●When battery-saving mode is set, bat-
tery depletion is minimized by stop-
ping the electronic key from receiving
radio waves.
Press twice while pressing and holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set,
the smart entry & start system cannot be
used. To cancel the function, press any
of the electronic key buttons.
●Electronic keys that will not be used
for long periods of time can be set to
the battery-saving mode in advance.
■Conditions affecting operation
The smart entry & start 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 entry &
start system, wireless remote control
and engine immobilizer system from
operating properly. (Ways of coping:
→P.399)
●When the electronic key battery is
depleted
●Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise
●When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device
●When the electronic key is in contact
with, or is covered by the following
metallic objects
• Cards to which aluminum foil is
attached
• Cigarette boxes that have aluminum
foil inside
• Metallic wallets or bags

3-2. Opening, closing and locking the doors
Before driving
• 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 digi-
tal 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
parking spot where radio waves are
emitted
If the doors cannot be locked/unlocked
using the smart entry & start system,
lock/unlock the doors by performing any
of the following:
●Bring the electronic key close to either
front door handle and operate the
entry function.
●Operate the wireless remote control.
If the doors cannot be locked/unlocked
using the above methods, use the
mechanical key. (→P.400)
If the engine cannot be started using the
smart entry & start system refer to
P.400.
■Note for the entry function
●Even when the electronic key is within
the effective range (detection areas),
the system may not operate properly
in the following cases:
• The electronic key is too close to the
window or outside door handle, 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 cover or 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 recep-
tion conditions, it may be detected by
the antenna outside the cabin and the
door will become lockable from the
outside, possibly trapping the elec-
tronic key inside the vehicle.
●As long as the electronic key is within
the effective range, the doors may be
locked or unlocked by anyone. How-
ever, 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 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 automatically be locked after
approximately 30 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 pos-
sibility that the door may not be
unlocked by the entry function. (Use
the wireless remote control to unlock
the doors.)
●Touching the door lock or unlock sen-
sor while wearing gloves may prevent
lock or unlock operation.
●When the lock operation is performed
using the lock sensor, recognition sig-
nals will be shown up to two consecu-
tive times. After this, no recognition
signals will be given.
●If the door handle becomes wet while
the electronic key is within the effec-
tive range, the door may lock and
unlock repeatedly. In that case, follow
the following correction procedures to

3-2. Opening, closing and locking the doors
wash the vehicle:
• Place the electronic key in a location 2
m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key
is not stolen.)
• Set the electronic key to battery-sav-
ing mode to disable the smart entry &
start system. (→P.124)
●If the electronic key is inside the vehi-
cle and a door handle becomes wet
during a car wash, a message may be
shown on the multi-information dis-
play and a buzzer will sound outside
the vehicle. To turn off the alarm, lock
all the doors.
●The lock sensor may not work prop-
erly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor
and attempt to operate it again.
●A sudden handle operation or a han-
dle operation immediately after enter-
ing the effective range may prevent
the doors from being unlocked. Touch
the door unlock sensor and check that
the doors are unlocked before pulling
the door handle again.
●If there is another electronic key in the
detection area, it may take slightly lon-
ger 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 2 m (6
ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance. (→P.422)
●Setting the electronic key to battery-
saving mode helps to reduce key bat-
tery depletion. (→P.124)
■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 vehi-
cle when operating the system from the
outside of the vehicle.
Depending on the position and holding
condition of the electronic 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 prevention function may not
operate.)
