3-2. Opening, closing and locking the doors
Before driving
The system can be operated when the
electronic key is inside the vehicle.
■Effective range (areas within which
the electronic key is detected)
(wagon)
When locking or unlocking the
doors
The system can be operated when the
electronic key is within about 0.7 m (2.3
ft.) of an outside front door handle and
back door. (Only the doors detecting the
key can be operated.)
When starting the engine or chang-
ing engine switch modes
The system can be operated when the
electronic key is inside the vehicle.
■Alarms and warning messages
A combination of exterior and interior buzzers as well as warning messages
shown on the multi-information display
are used to prevent theft of the vehicle and accidents resulting from erroneous
operation. Take appropriate measures
based on the displayed message. ( P.520)
When only an alarm sounds, circum-
stances and correction procedures are as follows.
●Exterior buzzer sounds once for 5 seconds
●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.

1383-2. Opening, closing and locking the doors
■Electronic key battery-saving func-
tion
When battery-saving mode is set, bat-
tery depletion is minimized by stopping
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.
■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.554)
●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 •Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wirele ss 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.555)
If the engine cannot be started using the smart entry & start system refer
to P.555.
■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.

3-2. Opening, closing and locking the doors
Before driving
• 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.
●Some models: When the lock opera-
tion is performed using the lock sen- sor, 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 effec-
tive range, the door may lock and unlock repeatedly. In that case, follow
the following correction procedures to
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.138)
●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
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 2 m (6
ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance. ( P.577)
●Setting the electronic key to bat- tery-saving mode helps to reduce key
battery depletion. ( P.138)
■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
