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 immobilizer system from operating properly. (Ways of coping: P.407)
●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 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
●I f w i n d o w t i n t w i t h a m e t a l l i c c o n t e n t o r
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.408)
If the hybrid system cannot be started
using the smart entry & start system, refer to P.408.
■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 hybrid system is started or power

3-2. Opening, closing and locking the doors
Before driving
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 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 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 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.141)
●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.431)
●Setting the electronic key to battery-
saving mode helps to reduce key bat- tery depletion. ( P.141)
■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

●When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady on, as steady means the vehicle is
able to move.
●When the hybrid battery (traction bat-
tery) is extremely cold (below approxi-
mately -30°C [-22°F]) under the
influence of the outside temperature, it may not be possible to start the hybrid system. In this case, try to start the
hybrid system again after the tem- perature of the hybrid battery increases due to the outside tempera-
ture increase, etc.
