Operation of each component
■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key
battery and the 12-volt battery from being discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of theoutside of the vehicle for 10 minutes or longer.
• The smart access system with push-button start has not been used for 5 days or longer.
●If the smart access system with push-button start 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.

■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the follow-
ing situations, the communication between the electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and immobilizer system from operating properly. (Ways of coping: →P. 76 7 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular 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 digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear

Operation of each component
■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 near the ground or in a high place, or too close to the rear bumper center when the trunk is opened.
• The electronic key is on the instrument panel, rear package tray or floor, or in the door pockets or glove box when the hybrid system is started or power 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 condi-
tions, it may be detected by the antenna outside 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 possible to start the
hybrid system if the electronic key is near the window.
●The doors may unlock or lock if a large am ount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the effec-
tive range. (The doors will automatically 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 possibility that the door may not be unlocked by the
entry function. (Use the wireless remote control to unlock the doors.)

■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 hybrid system
stops. (→P. 74 6 )
●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 neces-
sary. ( →P. 668)
• The smart access system with push-button start 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 3 ft. (1 m) 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
• Table lamps
•Glass top ranges
■When the electronic key battery is fully depleted
→ P. 668
■Customization
Settings (e. g. smart access system with push-button start) can be changed.
(Customizable features: → P. 807)
■If the smart access system with push-button start has been deactivated in a cus-
tomized setting
●Locking and unlocking the doors and opening the trunk:
Use the wireless remote control or mechanical key. ( →P. 1 3 4 , 76 7 )
●Starting the hybrid system and changing power switch modes: →P. 76 8
●Stopping the hybrid system: →P. 1 9 0
