■Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic 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 key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m)
of the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key 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.

Conditions aff ecting operation
The smart key system, wireless remote control and immobilizer system use
weak radio waves. In the following situations, the communication between
the electronic key and the vehicle may be affected, preventing the smart key
system, wireless remote control and immobilizer system from operating
properly. (Ways of coping: P. 594)
● 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 generates strong radio waves or electri-
cal noise
● When carrying a portable radio, ce llular phone, cordless phone or other
wireless communication devices
● 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 key (that emit radio waves) is 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 window

If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 594)
● Starting the hybrid system: P. 595
■ 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. 118)
● 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. 496)
• The smart key 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 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Charging cellular phones or cordless phones
• Induction cookers
• Table lamps

■ 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.
(The door lock prevention may not operate.)
■ Note for the smart key 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 door pockets or 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.
