Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again. (How-
ever, depending on the location of the electronic key, the key may be
detected as being in the vehicle. In this case, vehicle may be unlocked.)
Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the vehicle battery from being discharged while the
vehicle is not in operation 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 in an area of approximately 2 m (6 ft.)
of the outside of the vehicle for 10 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 at any doors except the driver’s door. 
In this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

Notes for locking the doors
Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
On hybrid vehicle, when the lock operation is performed using the lock
sensor, recognition signal 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. Place the key
in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, 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.
Notes for the unlocking function
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.
Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the handle
again.
If the door handle becomes wet while the electronic key is within the
effective range, the door may lock and unlock repeatedly. Place the key
in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
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. 679)

Security feature
If a door is not opened within approximately 30 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again.
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 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.)
If the smart entry & start system does not operate properly
Locking and unlocking the doors: Use the mechanical key. (P. 616)
Starting the engine (except hybrid vehicle) or the hybrid system (hybrid
vehicle): P. 617, 619
Electronic key battery depletion
The standard battery life is 1 to 2 years.
If the battery becomes low, an alarm will sound in the cabin when the
engine (except hybrid vehicle) or the hybrid system (hybrid vehicle)
stops. (P. 571)
As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. (P. 501)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps

Note for the push-button start system
Even when the electronic key is within the effective range (detection
areas), the system may not operate properly.
For example, the electronic key is on the instrument panel, luggage
cover, floor or in the glove box when the hybrid system is started or
“POWER” switch modes are changed.
Even if the electronic key is not inside the vehicle, it may be possible to
start the hybrid system if the electronic key is near the window.
To operate the system properly
Make sure to carry the electronic key when operating the system.
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.
